Alternate to 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_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;
}
}
