What version of PHP is Symfony using?

Question

I have been struggling with this for a few hours now. I am running CentOS 6.6. A few hours ago I was having issues with a Symfony project that required PHP 5.4+ because of some libraries required. So I installed version 5.4 and I used to have PHP 5.3.3.

PHP 5.4 allows some new features. Such as array shorthand declaration and binary data strings. Like this:

//array shorthand declaration
$arr = [1, 2, 3, 4]; //PHP +5.4

$arr = array(1, 2, 3, 4); //PHP 5.3.3

//binary data strings
0b001 //PHP +5.4

This is on the official documentation so here's a link to the source: https://secure.php.net/manual/en/migration54.new-features.php

However when executing those scripts I am getting errors as if I was not running PHP 5.4 for example I would get this one:

PHP Parse error:  syntax error, unexpected '[' in /vendor/wisembly/elephant.io/src/Engine/AbstractSocketIO.php on line 44

And the line of code would be:

//does not work
$data = [$event, $args]; //PHP 5.4 syntax

//it works
$data = array($event, $args); //PHP 5.3.3 syntax

This is the output of running php -v on the terminal

PHP 5.4.43 (cli) (built: Jul  8 2015 12:08:50)  
Copyright (c) 1997-2014 The PHP Group  
Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies

So based on this output I know I am running PHP version 5.4, the only thing that occurs to me is that somehow there is a configuration error somewhere and it is still using PHP 5.3.

So my question is how do I know what version of PHP is Symfony using? Thanks.

run `phpinfo()` on one of your pages and see what that gives you. its possible for you to have one version of php for the cli and one running from apache — castis, Jul 17 '15 at 23:39
Just to "confirm" that it isn't a Symfony configuration, why don't you write a simple php with an array and try to execute it? — Mindastic, Jul 17 '15 at 23:40
http://symfony.com/doc/current/reference/requirements.html says 5.3.9 — qooplmao, Jul 17 '15 at 23:49

When you run php -v, it show you the CLI's php version. Not the php version used for your script (run by your webserver).

You have multiple solutions to get the version used by your webserver.

Example with the function phpinfo(); in a .php page.

<?php
    phpinfo(); // Outputs information about PHP's configuration

Example directly from the command line (show you the same information displayed with an phpinfo())

php -i

Thanks, but strangely it says PHP Version => 5.4.43 – Leo Jul 18 '15 at 00:32
Which version did you tried (`phpinfo()` or `php -i`) ? – zilongqiu Jul 18 '15 at 00:47

Can you try to execute the `phpinfo();` in a php page ? please – zilongqiu Jul 18 '15 at 00:57
I was going to suggest something similar. Chances are that Apache is still pointing at another version of PHP on the machine. Checkout `phpinfo();` to make sure. – Kevin Nagurski Jul 20 '15 at 14:02

You can use the command symfony console about, which displays the PHP version near the end:
