Php parse error in Drupal 7 application

Question

I tried to run a Drupal 7 installation on my local environment which previously worked totally fine. I use Mac OS X. When requesting the website locally the browser shows:

Parse error: parse error in /Library/WebServer/Documents/.../xxx.module on line 7

Line 7 is

$variables['path'] = $base_url . "/sites/default/files/" . explode('public://',$file->uri)[1]

OR it returns an error with the code:

ERR_EMPTY_RESPONSE

The apache error file shows:

child pid 2114 exit signal Segmentation fault (11)

php -v returns

PHP 5.3.26 (cli) (built: Jul 7 2013 19:05:08) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies

The code seems not to be wrong. It's exactly the same running on another machine.

Answer 1

Array dereferencing was added in PHP5.4. Your server has v5.3.26, so this

explode('public://',$file->uri)[1];

isn't valid syntax.

You either need to upgrade to 5.4 (Homebrew makes that easy), or change your code:

$parts = explode('public://',$file->uri);
$variables['path'] = $base_url . "/sites/default/files/" . $parts[1];

Answer 2

Why don't you use file_create_url.

$variables['path'] = file_create_url($file->uri);
