Use the following function if you are using PHP 5.4 or lower.
It is a complete simulation of array_column() in PHP 5.5 created by me.
<?php
if(!function_exists('array_columns')){
/*
* array_column() for PHP 5.4 and lower versions
*/
function array_columns($input,$column_key,$index_key=''){
if(!is_array($input)) return;
$results=array();
if($column_key===null){
if(!is_string($index_key)&&!is_int($index_key)) return false;
foreach($input as $_v){
if(array_key_exists($index_key,$_v)){
$results[$_v[$index_key]]=$_v;
}
}
if(empty($results)) $results=$input;
}else if(!is_string($column_key)&&!is_int($column_key)){
return false;
}else{
if(!is_string($index_key)&&!is_int($index_key)) return false;
if($index_key===''){
foreach($input as $_v){
if(is_array($_v)&&array_key_exists($column_key,$_v)){
$results[]=$_v[$column_key];
}
}
}else{
foreach($input as $_v){
if(is_array($_v)&&array_key_exists($column_key,$_v)&&array_key_exists($index_key,$_v)){
$results[$_v[$index_key]]=$_v[$column_key];
}
}
}
}
return $results;
}
}
$testArray=array(
array(0=>'Girl','name'=>'Judy'),
array(0=>'Boy','name'=>'Jerry')
);
echo '<pre>';
print_r(array_columns($testArray,'name'));
print_r(array_columns($testArray,0,'name'));
?>
