php 数组操作

1、 过滤或删除数组中的某个值

<?php
$template_from_id_list = [
    1,2,3,'','the formId is a mock one',5
];
$template_from_id_list = array_filter($template_from_id_list,function($v){
    if($v == 'the formId is a mock one' || empty($v)){
        return false;
    }
    return true;
});
sort($template_from_id_list);    ////重新生成索引下标
print_r($template_from_id_list);
?>

 2、过滤或删除二维数组中的指定字段数组

<php 

$data = [
            [
                'id'=>1,
                'delete_status'=>2,
            ],
            [
                'id'=>2,
                'delete_status'=>1,
            ]
        ];
        $data = array_filter($data,function($vv){
            if($vv['delete_status'] == 2){
                return false;
            }
            return true;
        });
        sort($data);
        print_r($data);

?>
