If mail returns true, it doesn't mean that the email was sent properly, just that it was passed off to the host os or some sort of mail server. This might be sendmail or something else depending on how php and your webserver is configured. It could be that the messages are getting passed successfully to sendmail, but then sendmail is eating them. You should work to get mail() so that it successfully sends a message to an account, then go from there. Check out how your server is setup.

Are there any decent PHP CSS "compilers"? The only thing I could really find is the following and it's not very feature filled... http://interfacelab.com/variables-in-css-via-php/

supster posted:Are there any decent PHP CSS "compilers"? The only thing I could really find is the following and it's not very feature filled... Interesting idea, but it seems kind of over-engineered in my opinion. I'm pulling this out of my rear end, but would something like this work? Sorry if I'm missing your point by a mile: style.css.php php:<?php $red = "#f00"; $column1_width = 400; $column2_width = 300; header('Content-type: text/css'); ?> .fart_container {width: <?php echo ($column1_width + $column2_width); ?>px;} .fart {color: <?php echo $red; ?>;}

Why does ++$i execute faster than $i++?

BondGamer posted:Why does ++$i execute faster than $i++? What do you mean by faster? Like take less processor time? Or do you mean that with ++$i you will see $i incremented within the statement, while $i++ sees the value incremented afterward? If you mean the latter that is by design and how it works in all languages that support the ++ operator.

A few days ago I decided to see what type of neat text encryption PHP can do. I stumbled upon this and within the same execution cycle it works fine: php:<? //encrypt3.php?key=balls&text=i like to move it move it $key_value = $_REQUEST["key"]; $plain_text = $_REQUEST["text"]; echo "key = '$key_value' and text = '$plain_text'<br>"; $encrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $plain_text, MCRYPT_ENCRYPT); echo "encrypted text = '$encrypted_text'<br>"; $decrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $encrypted_text, MCRYPT_DECRYPT); $decrypted_text = trim($decrypted_text); echo "decrypted text = '$decrypted_text'";?> code:Comparing the output of my test script with the output from my main form, it's encrypting fine. It just seems the special characters aren't being transmitted to the server correctly when deycrpting. Could anybody please give me pointers why?

I wouldn't spit out raw binary to a browser for it to resubmit, you should probably encode it somehow (base64, for example).

I'm trying to graph Hard Drive utilization by partitions for a project I am working on. My goal is to allow user input of partitions of a server. From that point forward they can track changes in partition free space by entering the amount of free space on each partition at any given point of time. It can the be plotted out on a line graph. Here is some sample data: code:All I want is a good recommendation on a PHP graphing Class or package and maybe a push in the right direction.

DarkLotus posted:I would like to dynamically create a line graph that supports multiple partitions. Using the initial partition size and free space along with the date the partition was added give us a baseline for each partition. Each entry will then have a new date and freespace for the given partition. This should allow graphing by Date on the X axis and Size on the Y axis. The scale would be simple Y minimum would be ZERO, Y maximum would be the largest available partition size out of all of the partitions. In this example we are looking at one partition so the Y max would be 30 GB. The X axis would be by date, so the farthest to the left would be partition_create_date and the farthest on the right would be the last partition_entry_date. Have a look at jpgraph if you just want to generate images, but have you considered using either flash or javascript to do the plotting? Obviously it depends on what the client is and what it might support/be reasonable.

I also looked at PHP/SWF Charts which definitely looks much nicer but also more involved. I like the idea of displaying an image or a swf, and not having the browser draw the plots with javascript. This will all be web based obviously so IE / FF / Safari support is required.

Pinging this question again, and also a new one: When I use mysqli->bind_result and the result is a MySQL NULL, is the variable set to null or "NULL"?Golbez posted:Because of duz, I looked into using __get and __set, and kind of like them.

Golbez posted:Pinging this question again, and also a new one: When I use mysqli->bind_result and the result is a MySQL NULL, is the variable set to null or "NULL"? I am not sure, I think its either null or an empty string, but its certainly not a string with the word NULL in it. Execute the query "SELECT NULL AS myTestResult". Bind the result, then do var_dump on it to see what it spits out. As far as your other question. You are creating some whackiness by passing in overloaded properties that may or may not exist as far as the compiler is concerned. When you use bind_param you are binding a reference to the variable, not passing the value stored in the variable. That way you can modify the value of the variable right up until you call execute. When execute is called it then pulls the values. When you pass in the overloaded property it may not exist when execute is called. You can fix this by doing $val1 = $this->val1; $val2 = $this->val2; etc then bind $val1 and $val2 to the query. You could also switch to PDO and use bindValue instead. IMO PDO is easier to use anyways. Begby fucked around with this message at 20:47 on Jul 16, 2009 |

Yeah, I was hoping to avoid the extra variable settings but I'll probably end up doing that just for the sake of avoiding notices. (The code works as-is, just with notices)

I've started working on a CSS preprocessor writte in in PHP (and intended to be used in PHP applications) but I am a little unsure about which route to go regarding syntax. My initial thought was to borrow heavily from CleverCSS and Python to have syntax like this: code:So I figured that perhaps syntax like the following may be more fitting: code:I wanted to get some opinions from other PHP developers that may have less Python bias than I do and see what they might prefer. I am also open to suggestions for a different type of syntax than the above two. supster fucked around with this message at 01:09 on Jul 17, 2009 |
