问题描述
我基本上是在寻找http_build_query()
的反面.
I'm basically looking for the opposite of http_build_query()
.
我将以下内容作为字符串:
I have the following as a string:
foo=bar&bar[var]=foo
我想要以下内容(传递给http_build_query
):
And I want the following (to pass into http_build_query
):
array(
'foo' => 'bar',
'bar' => array(
'var' => 'foo',
)
)
推荐答案
You want parse_str()
. Pass it an array as the 2nd parameter and it will extract variables from the query string you give it into the array:
<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz
请注意,这是 http_build_query
上列出的第一个相关功能. 页面.
Notice this is the very first related function listed on the http_build_query
page.
