Alternate to array_column()

Question

I have used array_column() in a project, and after uploading I found out that only PHP 5.5 or above support this function, and I think the hosting I use don't support PHP 5.5 or above.

So I want to know if is there any alternate to fix this error?

This is how I am using array_count in my project:

array_count_values(array_column(json_decode(json_encode($queryResultArray), true), $idForBar)); 

This is working fine in my local xampp and wampp also, but on server it is giving issue. Looking any alternate function or solution.

Add your own function array_column if you PHP version does not support it:

<?php if (! function_exists('array_column')) {     function array_column(array $input, $columnKey, $indexKey = null) {         $array = array();         foreach ($input as $value) {             if ( !array_key_exists($columnKey, $value)) {                 trigger_error("Key \"$columnKey\" does not exist in array");                 return false;             }             if (is_null($indexKey)) {                 $array[] = $value[$columnKey];             }             else {                 if ( !array_key_exists($indexKey, $value)) {                     trigger_error("Key \"$indexKey\" does not exist in array");                     return false;                 }                 if ( ! is_scalar($value[$indexKey])) {                     trigger_error("Key \"$indexKey\" does not contain scalar value");                     return false;                 }                 $array[$value[$indexKey]] = $value[$columnKey];             }         }         return $array;     } }
