Further to loreiorg's script
in order to preserve duplicate keys when combining arrays.
I have modified the script to use a closure instead of create_function
Reason: see security issue flagged up in the documentation concerning create_function
<?php
function array_combine_($keys, $values){
$result = array();
foreach ($keys as $i => $k) {
$result[$k][] = $values[$i];
}
array_walk($result, function(&$v){
$v = (count($v) == 1) ? array_pop($v): $v;
});
return $result;
}
?>
