Question

This is my code that is working nice on my localhost:

<?php
$list = array();
array_map(function($var){}, $matches_array_1);
foreach ( $matches_array_1 as $value ) {
    $key = $value['team'];

    if (array_key_exists($key, $list)) {
        $list[$key]['team_points'] += $value['team_points'];
        $list[$key]['team_occurrences'] ++;
    } else {
        $list[$key] = $value;
        $list[$key]['team_occurrences'] = 1;
    }
}
usort($list ,function($a, $b){ $a = $a['team_points'] ; $b = $b['team_points'] ; return ($a == $b) ? 0 : (($a < $b) ? 1 : -1 ) ;});

?>

But on the server it throws an error:

Parse error: syntax error, unexpected T_FUNCTION, expecting ‘)’

for this line:

array_map(function($var){}, $matches_array_1);

My localhost WAMP PHP version is 5.4.3

My server PHP version is 5.2.17

I would like to change th code so it works on both environments.

Thanks for any advice.
