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; } }
