Function similar to in_array() but it recursively searches a multi-depth array.
<?php
function deep_in_array($value, $array, $case_insensitive = false)
{
foreach($array as $item)
{
if (is_array($item))
{
$output = deep_in_array($value, $item, $case_insensitive);
}
else
{
$output = ($case_insensitive) ? strtolower($item)==$value : $item==$value;
}
if ($output)
{
return $output;
}
}
return false;
}
?>
