This is my array.

code:

Array
(
    [0] => Choose type...
    [1] => english
    [2] => science
    [3] => history
)

Is there any way i can get the array to look like this:

code:

Array
(
    [] => Choose type...
    [english] => english
    [science] => science
    [history] => history
)

Yes, although why do you want it to look like that?

PHP code:

$myarray = array (
    '' => 'Choose type...',
    'english' => 'english',
    'science' => 'science',
    'history' => 'history'
);

Working specifically from what given, and assuming "0" will always end up being blank:

PHP code:

$output = array();
foreach ($array AS $key => $value)
{
    if (!$key) { $output[''] = $value; }
    else { $output[$value] = $value; }
}

I was surprised you can have a blank string ('') for an array key, but here we are.

From the interactive prompt:

code:

php > $horror = array( '' => 'empty string', 0 => 'zero', null => 'null, lol');
php > 
php > 
php > print_r($horror);
Array
(
    [] => null, lol
    [0] => zero
)

Looks like the null got stringified. At least that's ... something approaching sane.

IIRC all array keys are strings. Even the default numeric keys are really the decimal string representations of the nonnegative integers.

Thanks for this.

Hammerite, The reason I wanted to do it this way is because I'm getting the arra values from a database and i wanted to populate the select box with these values. The thing is, what gets submitted to the form is '0' or '1' or '2' etc, and I wanted to submit a more friendly string.

Hammerite posted:

Looks like it's the other way around - numeric strings are cast to integers. Can't say this makes me happy. The bit about floats being cast to ints ... hasn't bitten me in the past but that doesn't mean I don't like it.

Here's the documentation:

PHP.net posted:

Additionally the following key casts will occur:

Strings containing valid integers will be cast to the integer type. E.g. the key "8" will actually be stored under 8. On the other hand "08" will not be cast, as it isn't a valid decimal integer.
Floats are also cast to integers, which means that the fractional part will be truncated. E.g. the key 8.7 will actually be stored under 8.
Bools are cast to integers, too, i.e. the key true will actually be stored under 1 and the key false under 0.
Null will be cast to the empty string, i.e. the key null will actually be stored under "".
Arrays and objects can not be used as keys. Doing so will result in a warning: Illegal offset type.

We're getting 5.3 this weekend! And MySQL 5.5! :holy:

I've been trapped in a 5.1 gulag for years. What massive stuff do I need to know about from 5.2 and 5.3? The short list I've come up with in the last 30 seconds is:
1) Array dereferencing, gently caress yeah.
2) Namespaces. Know nothing about them or why they're useful. What is the point?
3) Frameworks. Oh god, frameworks. I so very much want to move our site to a framework. But, being in 5.1, my only experience is with an old version of Zend. What is the current hotness?
4) InnoDB. This is MySQL, but it also means I have to change many many many of our queries to handle transactions. We're not converting from MyISAM immediately but it's something we'll be doing.
4a) mysqli or PDO. Oh gently caress me I've been wanting this for so long, it's not that I couldn't but I always wondered if there was any point without a framework. ... There probably is, actually, and I could just shoehorn one in, but eh. This point is more e/n than anything else.
5) I will be using the poo poo out of the datetime objects.

Anything else? I'm excited! :woop:

1) That didn't happen until PHP5.4, so don't go using it yet.
2) I love them. Instead of having a long class named Zend_Db_Something_Or_Other_Factory, you could throw that in the Zend\Db\Something\Or\Other namespace, and your class would just be named Factory. Then to use it, you can do: use Zend\Db\Something\Or\Other\Factory; $f = new Factory;

You can also alias Factory to another name to avoid conflicts: use Zend\Db\Something\Or\Other\Factory as ZendFactory; $f = new ZendFactory.
3) Symfony2 and Zend2 just released new versions of their frameworks. I'm partial to Symfony2 personally but I have no experience with Zend2.
4) Good, hopefully you'll be using PDO (or an ORM which will use PDO).
4a) Always use PDO. "But mysqli is nice!" Nope, just use PDO.
5) DateTime is a great library.

I urge you to just upgrade to 5.4. That way you can get array dereferencing and you get the built in server which is awesome. No more setting up vhosts for small projects. Symfony2 has it built into their console:

php app/console server:run

Bam, go to http://localhost:8000/ and your Symfony2 app is running right there. So nice.

Edit: Oh yeah, 5.4 also has short JavaScript style arrays which are nice (but harder to grep for):

$a = ['a', 'b', 'c'];

. 5.3 at least is a huge step up from (I'm guessing 5.1.6 which is what shipped with RedHat/CentOS forever).

What version of 5.3? If you use any XML-RPC libraries, 5.3 earlier than 5.3.8 has a bug with them. That was the biggest (and only) thing that got me with 5.3.

Man, reading this thread really makes me want to get my teeth back into a bit of PHP. The last time I really touched it was with the release of PHP 5 and the whole OOP thing.

I create apps in .Net at work but there's something about PHP which makes it much more enjoyable to code in.

Are there any must read articles I should look at to talk me through the major new features in the last few years? Or just feel free to throw some words at me and I'll look them up.

Also, this has probably been asked a million times but what's generally considered the best template system these days? Last thing I used was smarty.

# ? Sep 21, 2012 21:04

musclecoder: Oct 23, 2006; I'm all about meeting girls. I'm all about meeting guys.

PHP has matured, but still has years and years of lovely history you have to put up with.

Most of the things that you find in PHP you find in other competent development teams:

* Automated testing of all types
* Builds with Phing
* Continuous integration
* Continuous deployment
* Database migrations
* Vendored code
* http://www.12factor.net/ is a great site by Heroku showing what a good web app is made up of.

Definitely not Smarty. I use Symfony2 which uses Twig and I find it enjoyable. One nice construct I like is the {% for %} {% else %} block:

code:

{% for var in list %}
    <strong>{{ var }}</strong><br>
{% else %}
    <strong>Sorry nothing to list!
{% endfor %}

That's always a construct I wish a language would have. PHP is still very verbose compared to Python and Ruby. And if you're gonna use a database, use Postgres.

Experto Crede: Aug 19, 2008; Keep on Truckin'

I'm pretty drat new to php, and I'm trying to wrap my head around php's read_exif_data function. As a test, I want it to read the data's "Make" tag and echo text depending on if the make is a certain one.

So far I have this:

php:

<?php
$image = "IMG_20120922_125625.jpg";
$exif = exif_read_data($image,"Make", 0, false);
if ($exif == "HTC"){
    echo "HTC";
}
else{
    echo "Not HTC";
}
?>

But regardless of the image (I have a test image from a samsung and htc camera), it just echoes "HTC". I know it's probably something really simple I'm doing wrong (Getting a bit confused by the info on the php manual), but I can't see it :downs:

Any advice?

This. exif_read_data returns an array, or false if it can't find anything.

If you print_r($exif) you'll see how you need to reference the returned array to get what you want. (It'll probably be something like $exif['Make'])

Yeah, PDO makes sense, especially since we are open to switching away from MySQL in the future.

As for late static binding, it seems useful, but my objects are so pedestrian and simple as to only barely inherit, let alone do anything complex enough for that. :sigh:

McGlockenshire: Dec 16, 2005; GOLLOCKS!

If you're new to MVC, Zend Framework is the worst possible choice. Especially version 1.

Not that there's anything wrong with it, really. The problem is that ZF is a horribly complex beast that takes hints from Java's way of doing things. It's a bad place for beginners to start.

You don't need a framework to follow the principals of MVC.

However, I've been casually looking at jobs and a lot of them require knowledge of Zend. Not all, but a lot so I thought it would give me an advantage.

You also want to stop using the word Zend without a qualifier.

Zend is a company. They produce an IDE (Zend Studio), an integrated server product (Zend Server), and sponsor but do not control the development of an open source library (Zend Framework). None of the three require the others, and knowing one does not teach you anything about the others. When talking about the framework, just "ZF" is enough to give context to most people that know it.

Thanks for this - I hadn't heard of Laravel and it looks quite interesting.

Edit:

So I've been looking into Laravel, playing around with it a bit, and I'm struggling to get the hang of the Eloquent ORM. In my schema I have a USERS table and a TEAMS table, each user record has a TEAM_ID (which may be null) representing the football team they support.

I must be misunderstanding something, because I would call this a one to many (one team can be linked to any number of users, but each user will be linked to just one team). According to the docs I would reflect a one-to-many relationship in the code by saying:

PHP code:

function teams()
{
    return $this->has_one('team');
}

But when I do this it looks for a 'USER_ID' in the TEAMS table. I don't understand why it would do that - surely if I'm saying the USER model has_one TEAM it would imply a foreign key of TEAM_ID in the USER table.

I'm clearly misunderstanding something fairly fundamental, someone please help!

Laravel comes with the Auth stuff built-in, it seems like it's going to be the next big thing in my opinion as it's incredibly well made and actually makes good use of the improved OO in PHP 5.3
