php提取json变量值

……{"pid":"PR18","order":21,"title":"xviii","h":893},{"pid":"PA1","order":22,"title":"1","h":898},{"pid":"PA3","order":24,"title":"3","h":895}……

要提取的是PR18、PA1、PA3……放到一个数组变量里

可以使用正则，也可以使用split（explode），下面是用正则的例子：

<?php
$s='……{"pid":"PR18","order":21,"title":"xviii","h":893},{"pid":"PA1","order":22,"title":"1","h":898},{"pid":"PA3","order":24,"title":"3","h":895}……';
if (preg_match_all('|"pid":"(\S+?)"|', $s, $reg)) print_r($reg[1]);
?>

代码测试通过，输出结果如下：

Array
(
[0] => PR18
[1] => PA1
[2] => PA3
)
