Alternate (polyfill) for array_column()

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_column 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;
    }
}
