如果没有提供 callback 函数,array_filter() 将删除 input 中所有等值为 FALSE 的条目。
删除数组中为空值的元素就可以使用这个函数。

复制代码 代码如下:


//删除数组中的一个元素
function array_remove_value(&$arr, $var){
foreach ($arr as $key => $value) {
if (is_array($value)) {
array_remove_value($arr[$key], $var);
} else {
$value = trim($value);
if ($value == $var) {
unset($arr[$key]);
} else {
$arr[$key] = $value;
}
}
}
}
