在PHP

Question

拥有以下字符串：

"[{"name":null,"value":"","target":null,"alias":"","required":1,"showNull":0}]"

如何从1部分获取required？我只需要1。

提前致谢。

Answer 1

假设字符串始终为JSON，请使用json_decode()：

$array = json_decode('[{"name":null,"value":"","target":null,"alias":"","required":1,"showNull":0}]');

现在您可以按如下方式访问required选项：

$array[0]->required;

Answer 2

您可以使用json_decode：

<?php
$string = '[{"name":null,"value":"","target":null,"alias":"","required":1,"showNull":0}]';
$string_array = json_decode($string, true);
echo $string_array[0]['required'];
?>

Answer 3

使用函数json_decode和current：

在单行中

$str = '[{"name":null,"value":"","target":null,"alias":"","required":1,"showNull":0}]';
$required = current(json_decode($str))->required;
