<?php
function error_handle($level, $message, $file = '', $line = 0){
array_multisort($a, SORT_ASC, $b);
}
set_error_handler('error_handle');
$data = [['aa'=> 'bb',], ['aa'=> 'bb',],];
$fusion = $data;
class classWithToString {
}
class classWithoutToString { }
$inputs = array(
'instance of classWithToString' => new classWithToString(),
'instance of classWithoutToString' => new classWithoutToString(),
'undefined var' => @$fusion,
);
var_dump(array_multisort($inputs, SORT_NUMERIC));Resulted in this output:
