PHP中可以自动分割查询字符的Parse_str函数使用示例

   这篇文章主要介绍了PHP中可以自动分割查询字符的Parse_str函数使用示例,小编也没见过的一个函数,这下分割URL中的查询字符串就方便了,需要的朋友可以参考下

  直接上代码:

  代码如下:

  $str = "1&errid=1&fee=2&balance=2582&fails=&msgid=634541149212681528&msg=全部发送成功。";

  parse_str($str, $output);

  echo $output['msgid']; //输出 634541149212681528

  定义和用法

  parse_str() 函数把查询字符串解析到变量中。

  语法

  parse_str(string,array)

  参数 描述

  string 必需。规定要解析的字符串。

  array 可选。规定存储变量的数组名称。该参数指示变量存储到数组中。

  提示和注释

  注释:如果未设置 array 参数,由该函数设置的变量将覆盖已由同名变量。

  注释:php.ini 中的 magic_quotes_gpc 设置影响该函数的输出。如果已启用,那么在 parse_str() 解析之前,变量会被 addslashes() 转换。

  例子

  例子 1

  代码如下:

  parse_str("id=23&name=John%20Adams");

  echo $id."

  ";

  echo $name;

  ?>

  输出:

  代码如下:

  23

  John Adams

  例子 2

  代码如下:

  parse_str("id=23&name=John%20Adams",$myArray);

  print_r($myArray);

  ?>

  输出:

  复制代码 代码如下:

  Array

  (

  [id] => 23

  [name] => John Adams

  )
