Needed depth of the dimension for arrays might be different by cases, so I made this. The default
of switch might not be 'max' though.
<?php
function array_dimension($array, $option = null) {
if(!is_array($array)) {
return 0;
} elseif(!$array) { // if the element does not exist
return 1;
} else {
switch(strtolower($option)) {
case 'first':
$keys = array_keys($array);
return array_dimension($array[$keys[0]], $option) + 1;
case 'last':
$keys = array_keys($array);
return array_dimension($array[$keys[count($keys) - 1]], $option) + 1;
case 'min':
foreach($array as $key => $val) {
$dems[$key] = array_dimension($val, $option);
}
return min($dems) + 1;
case 'max':
default:
foreach($array as $key => $val) {
$dems[$key] = array_dimension($val, $option);
}
return max($dems) + 1;
}
}
}
?>
