我的表格有问题。当我使用按钮时,它使用post方法到当前地址而不是在表单中指定的地址。我不知道那种形式有什么问题。我真的很感激一些帮助。

答案 0 :(得分:1)
看起来你有一个错字:
$a = [
['value' => 1, 'text' => '1 Hour'],
['value' => 12, 'text' => '12 Hour'],
['value' => 24, 'text' => '1 Day'],
];
$b = [
['value' => 12],
];
function comparator($a, $b)
{
return $a['value'] - $b['value'];
}
$c = array_udiff($a, $b, 'comparator');
print_r($c);
