this may be the dumbest loving question ever, but you mean don't save image files into a database, right? Or do you mean "don't save image data like file names and alternate text, etc. into a database"?

Sorry if this is a waste of Internet, but I'm trying to teach myself object-oriented php for developing data driven sites. That said, are there any good books on this that I could look at (to supplement my lurking and poo poo posting ITT)?

Don't save the actual image data itself in a db. Save the image as a file, store the path to that file in the db.

But don't save images into a database. Databases are for data, the filesystem is for files.

imagejpeg with a NULL as the second parameter will displayooooooooooooh I see. ... That's pretty smart. :eng99:

As for saving the images to the database, I generally agree, but in this case we're probably doing worse things with image storage than that. (See a page or two ago where I admitted to storing image data in a session variable)

There's also php's extract() which will dump array variables into the current context as individual variables. It's like unpacking array items with ** in Python.

I just installed a php 5.2.14 and set the extension_dir to c:\PHP\ext, but when I run a page that calls phpinfo it says extension_dir is still C:\php5

I don't have any other ini files except the one that's in the php folder, I even copied that one to the same directory where the php file is that calls phpinfo, and still no luck.

more info Im running IIS 6 and the application mapping for the .php extension is to php5isapi.dll

I tried renaming php.ini to php5.ini but it's still using the default values

mik: Oct 16, 2003; oh

I'm sick and tired of this. Can someone please tell me why I keep getting a Fatal memory error when I run this script?

I have a function that scrapes data from Yahoo Finance and puts the data into a table in my database. Because I'm grabbing almost 4000 stocks (i.e the function runs 4000 times) in order to avoid timeouts I have the script do 100 at a time, then the page reloads, the script gets the next 100 and so on.

However, nine times out of ten, at some point during the procedure I get the following error:

code:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4194304 bytes) in
 /home/username/domains/domain.net/public_html/opg/functions.php on line 122

Sometimes it's large like 4mb above and sometimes it's just trying to allocate 71 bytes or something tiny.

The function itself is as follows:

php:

<?

for(i=0;$i<100;$i++){

      getyahootickerdata($tickers[$i],"2010-01-01","2010-08-13");

}


// when this completes the page reloads and loops through 100 more tickers




function getyahootickerdata($ticker,$startdate,$enddate){

    list($start_year,$start_month,$start_day)    =    split("-",$startdate);
    list($end_year,$end_month,$end_day)            =    split("-",$enddate);

    $yurl        =    "http://ichart.finance.yahoo.com/table.csv?s=".trim($ticker)."&a=".($start_month-
1)."&b=".$start_day."&c=".$start_year."&d=".($end_month-
1)."&e=".$end_day."&f=".$end_year."&g=d&ignore=.csv";

    if(url_exists($yurl)){

        $fname             = fopen($yurl,'r');

        while(($csv_line = @fgetcsv($fname,500,",")) !== FALSE){
                $date_array[]    =    $csv_line[0];
                $open_array[]    =    $csv_line[1];
                $close_array[]    =    $csv_line[4];
                $volume_array[]    =    $csv_line[5];
                $adj_close_array[]    =    $csv_line[6];
        }
        fclose($fname);

        $csv_line_count    =    count($date_array);
    
        for($lc=$csv_line_count-1;$lc>0;$lc--){
            $gap    =    ($open_array[$lc]/$adj_close_array[$lc+1]-1);
            $chg    =    ($close_array[$lc]/$open_array[$lc]-1);
            $clscls    =    ($adj_close_array[$lc]/$adj_close_array[$lc+1]-1);    
        
            $input_array[]    =
    "(NULL,'".$ticker."','".$date_array[$lc]."','".$open_array[$lc]."','".$close_array[$lc]."','".$gap."',
'".$volume_array[$lc]."','".$chg."','".$clscls."')";
        
        }
        
        
        dbconnect();
        $query    =    'INSERT INTO yahoo_data VALUES'.implode(',',$input_array);
        mysql_query($query);        
        dbclose();
        
        $csv_line = null;
        $input_array = null;
        $date_array = null;
        $open_array = null;
        $close_array = null;
        $volume_array = null;
        $adj_close_array = null;    
        
        
        
        unset($csv_line);
        unset($input_array);
        unset($date_array);
        unset($open_array);
        unset($close_array);
        unset($volume_array);
           unset($adj_close_array);
                
    }    

}

?>

The error, when it happens (as I said 90% of the time) always happens on one of the following lines:

php:

<?
                $date_array[]    =    $csv_line[0];
                $open_array[]    =    $csv_line[1];
                $close_array[]    =    $csv_line[4];
                $volume_array[]    =    $csv_line[5];
                $adj_close_array[]    =    $csv_line[6];
?>

I've played with the line length parameter of fgetcsv, I've tried only doing 5 tickers at once, but i keep getting out of memory errors. I'm using a fast host (https://www.medialayer.net) so I don't suspect the server itself is overloaded by other people, it happens at all times of the day.

The reason I populate the arrays then loop through them to put the info in the database is because the .csv file i read the data from is in descending date order and I need my table to be in ascending order. I could do some wizardry and flip my table after all the data is in, but the script still shouldn't be running out of memory seeing as how the files that are read are only 20KB. Sometimes the error happens early on like stock 400, sometimes it dies almost at the end like stock 3500.

Where am I leaking memory? Feel free to mock my code.

What do you care what order the data hits the db in? Number it appropriately as it goes in, and use ORDER BY when pulling it out later. Rather than using a php script to buffer the whole output.

phpinfo() shoul tell you where it it loading php.ini from. I've seen it try C:\php (or C:\program files\php) and C:\windows. Try naming it php-isapi.ini, php-cgi.ini or pnp-fcgi.ini. When php DOES load an ini, phpinfo() tell you which one it loaded.

I usually run php5 trough fastcgi, so in myu case php-fcgi.ini is the one it looks for.

It's not exactly a php question per se, but I'm trying to find the best way to address this in PHP:

I'm doing up a program to handle scheduling for a setup managing adverts. This means that an entire day has to be broken up into 10 second segments, with long, feature length items and then some short adverts - with the option to move these around if necessary. At first I considered setting up the appropriate table with an entry for each 10 second gap (longer features could span multiple rows), but discarded this a it led to massive tables and slow db access times. I then considered simply using a text field, writing the times and items to play into there, and processing the information accordingly when it came in or out.

I then ran into the problem of displaying this information nicely on the scheduling page - pretty much any way I do it, that many segments ends up scrolling across the page, even at a high resolution. I'd use GD to generate a nice image representing the data, but then moving items around becomes problematic.

Ultimately, I can make it all work with tables and forms, but I can't help but feel I'm missing some better way of doing this, and am at a loss. Any ideas?

Well if you're displaying one day then 10 second segments could be 6*60*24=8640 rows so how do you expect to present that in a user interface? It's almost like you want to deal with groups of information at different resolutions of detail.

As far as storing events (timestamp+duration) in a database then I've used Postgres 8.4 with timestamps and intervals. You can then select an event and join its timestamp against a dynamically generated table of dates at an arbitrary resolution by using generate_series().

I don't know if this is the most efficient way of doing it but it's fast enough for me.

Those are some great points - Breaking down the times into smaller sections (and hell, using GD to give birds eye view of larger segments of data) would work well as although it might require more page refreshes, these could at least be done reasonably quickly.

I'm using MySQL, but it appears that it also allows date calculations as you've described, which would be more sensible than trying to run the same processes through PHP - though I will have to study up on it, as it's not something I've ever considered doing with a database before.

Thank you for your help!

It's trying the windows dir, I'm running ISAPI, so I tried renaming it php-isapi, php5 even php-cgi, but it's still looking in windows. I put a copy of php.ini in the windows dir, but it's still loading all the defaults and telling me it's not loading an ini file.

I even put an ini_set('extension_dir','C:/PHP/ext'); before the phpinfo call, but it seems to be ignoring that too.

Solved: apparently php run in ISAPI only loads its ini file when w3wp.exe is run, so recycling its application pool in IIS fixed the problem (http://forums.iis.net/t/1134052.aspx)

You could use GROUP BY in your sql select, then you dont have to bother with any logic in PHP.

So my PHP installation now knows where to look for my MySQL extensions, and the lines telling it to load them have been un commented, but PHP will only load mbstring, it ignores the mysql extensions

When I attempted group by with this select stament only one row for each 'class' was returned.

However when changed to order by, all were displayed.

I got bored the other day and decided to test some things I had read about string handling in PHP.

I made this in order to do that. (linked because it's kind of long)

Now I'm wondering how valid are these tests are because I'm getting some odd results - on PHP 5.2.5 on Windows (using Apache), this king of loop:

php:

<?
for($i = 0; $i < count($array); ++$i){
   $something .= $array[$i];
}
?>

is consistently about 100 times faster than this:

php:

<?
$count = count($array);
for($i = 0; $i < $count; ++$i){
   //same as above

Notes:

obviously I'm not bothering to measure the memory usage, and I'm probably straight up using less memory than you. But my results (1and1 shared linux server) are, as I said, more what you would expect - unless the windows php interpreter is optimising that particular construction (possible?)

Constants are slow?!?

foreach is fast; if you really have to loop through 300k element arrays, use foreach + break

Been working on this site in my free time, I am by no means good at php/html as this is the first site I have built. What is a good way to approach the difference in browser/screen resolutions that a page may be viewed in. For example when I view this page on my laptop there is a scroll bar on the bottom.

btw I am using absolute positioning, which may make this more difficult.

I'm doing the tests primarily because it's a very common idiom at my company to do poo poo like this:

php:

<?
while($something == true){
  //20 or so lines of
  $buffer .= "blah blah ".$whatever." the end\n";
  //lather, rinse, repeat 500 times - maybe 10000+
}

echo $buffer; //$buffer can be pretty long at this point
?>

Usually I try to replace it with an array or array of arrays, then a foreach and/or implode, but I wanted to make sure I wasn't creating a new problem based on bad information from random blogs. Of course, I try to get the data out of PHP and into Apache's buffer as quickly as possible.

The same tests on my Dreamhost account have the pre-counted loop just 50 times slower than the naive loop. I suppose I could dig through the byte code - woo

Given that it looked like your code was building some large strings in its tests; have you tried running the tests in isolation, or even just in the opposite order?

I mean; if you want to test the faster way to create longish strings in a large loop, you first test the faster loop method in isolation (doing something constant and simple that doesn't chew up memory), then the faster concatenation method in isolation (by using the same loop method throughout)

I think you'll get a result of foreach + implode being best.

i.e.

php:

<?
function format_huge_data($data, $formatter, $pre, $post, $between)
{
  $output = array();
  foreach($data as $datum)
    $output[] = $formatter($datum);
  return $pre . implode($between, $output) . $post;
}
?>

Note: in which case its worth testing array_map() as well?

Anyone can recommend an S3 library for PHP ? There's two dozens of them out there and it is hard to pick which one is the correct one to use in a big project, they all look like some basic proof of concept not maintained anymore.

The project runs PHP 5.3.3 on IIS 7. I don't need advanced features like user creation or manage access rights, all I really need is to store backups of files uploaded by my users.

Thanks !

DOH, forgot to say I need reduced redundancy storage. That one doesn't support it. It would also be a nice indication that the library is still actively maintained.

I'll look into it to see if I can add it myself.

EDIT: Yeah it was easy to add RRS support, that library will be perfect. Thanks !

Hungarian notation in PHP: The best idea, or the bestest idea? (or probably not) New work has me doing it, and after a while it becomes second nature, but I'm pretty sure it's not actually useful. At the very least, it's now given me a standard $b for a throwaway boolean, stands out a little more than my previous $x. :v:

Stupid question, I'm sure, but I'm calling an SQL stored procedure in PHP using sqlsrv_query. I'm providing an out parameter which receives a string, but it seems I have to initialise it in order to get anything sensible out. The problem is that the returned value is truncated to the length of the string I use to initialise the variable. Is there any way to avoid this or will I just have to initialise the variable as

code:

$var = "                                    ";

etc...

My PHP is rusty so I wasn't sure if there was a way to initialise a string as an empty string of a given length...

I don't know how sqlsrv_query works, but you could use str_pad.

code:

$var = str_pad('', 1000);

Would create a string with 1000 spaces.

Awesome. Thanks. Should've thought about padding. I'm sure there's a better way to initialise the parameter, but I'm just prototyping right now.

KuruMonkey's str_repeat is probably an ever-so-slightly 'purer' solution. But this sounds like a very strange error on sqlsrv_query's part.

Hm. Just wondering, is it necessary to run a mysql_num_rows > 0 before doing a while $x = mysql_fetch_assoc? I suppose it might be cleaner, but if zero rows were returned, then the while wouldn't even attempt to run it, right?
