Is there a PHP function to convert a query string to an array?
提问by Darryl Hein
I'm basically looking for the opposite of http_build_query().
我基本上是在寻找http_build_query().
I have the following as a string:
我有以下字符串：
foo=bar&bar[var]=foo
And I want the following (to pass into http_build_query):
我想要以下内容（传递到http_build_query）：
array(
'foo' => 'bar',
'bar' => array(
'var' => 'foo',
)
)

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:
你要parse_str()。将数组作为第二个参数传递给它，它将从您提供给数组的查询字符串中提取变量：
<?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
Notice this is the very first related function listed on the http_build_querypage.
请注意，这是http_build_query页面上列出的第一个相关功能。
