PHP: syntax error, unexpected '[' when using array_map

Question

I've been creating a php script for a project and have been running it on my development server which is running PHP 5.4.17

I need to move it over to my production server which is running PHP 5.4.19

When using the array_map function on my development server I got the results I needed with no problem.

On my production server I get the parse error:

Parse error: syntax error, unexpected '[' in /path/to/script/ on line 219

My code used was:

$arr = array_map(
    function($results_titles, $results_image, $results_summary, $results_dates, $results_links) {
        return ['title' => $results_titles, 'image' => $results_image, 'summary' => $results_summary, 'date' => $results_dates, 'link' => $results_links];
    },
    $results_titles, $results_image, $results_summary, $results_dates, $results_links
);

You've confused PHP and JS syntax) In PHP array initialized with: array(...), not [...] — hindmost

I don't remember since which version using [array_elements] was valid, maybe the problem is there, try using the classic structure: return array('title => $result_titles, etc...); I would keep using that syntax for a while, just in case xD — aleation

@hindmost since 5.4.0 you can use [] directly for the arrays too. OP, I think you are on a version prior to 5.4.0, check this link, your code should be valid on >5.4 php.net/manual/en/migration54.new-features.php — aleation

The new array syntax comes up with PHP 5.4.

So make sure your php version in your server is >= PHP 5.4

Note: the cli and the web server(eg: apache) could run different version of php.
