Symfony2 on php 5.4

Question

I need to change my Symfony2 website to a new server and I've noticed that the new server is currently installed php 5.4, when Symfony2 need a minimum of 5.5.9. By doing some tests they are taking place some errors like:

php.CRITICAL: Fatal Parse Error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) {"type":4,"file":"/home/admin/web/websitename.com/app/vendor/doctrine/common/lib/Doctrine/Common/Proxy/ProxyGenerator.php","line":62,"level":6143,"stack":[]} []

which is probably product of the version. I wonder if anyone has had this problem and has installed a Symfony2 in php 5.4, maybe down to an older version of the framework. I know that the easy way it would be to update the version of php but currently that's not an option.

Thanks in advance

Its actually Symfony3 that uses 5.5.9, Symfony2.8 still uses 5.3.9. — Flosculus, Feb 09 '16 at 17:01
after composer install you should get messages about incompatibility — john Smith, Feb 09 '16 at 17:08
I just upload the source code, installation was in localhost with a 5.5.11 version. — abdiel, Feb 09 '16 at 17:17
@DevDonkey preferably a dedicated or virtual private server :P — Flosculus, Feb 09 '16 at 17:22
@Flosculus apparently symfony 2.8 was not the problem, instead Doctrine use the function ::class that appears after php 5.5. — abdiel, Feb 10 '16 at 13:59

Moving a Symfony2 project to another server which have a different version of php (especially when it's a lower version) causes recurrently an error like yours.

Try to remove your vendor directory, maybe backup your composer.lock and redo a fresh installation by running composer install .

Also, manually remove all in the cache directory and verify the permissions of your server directories are the first things to do.

Since the problem seems to be in doctrine common bundle I try with some old version of it, looking for some one compatible with php 5.4, specifically someone when the function::class is not used. Finally it work with the next combination:

"doctrine/common": "2.4.2",
"doctrine/dbal": "2.4.4",
"doctrine/orm": "2.4.7",
"doctrine/doctrine-bundle": "~1.2"

Update composer and done.
