parse_str

(PHP 4, PHP 5)

parse_strParses the string into variables

说明

void parse_str ( string $str [, array &$arr ] )

Parses str as if it were the query string passed via a URL and sets variables in the current scope.

Note:

To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on variables from external sources.

Note:

The magic_quotes_gpc setting affects the output of this function, as parse_str() uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables.

参数

str

The input string.

arr

If the second parameter arr is present, variables are stored in this variable as array elements instead.

返回值

没有返回值。

更新日志

版本 说明
4.0.3 The arr parameter was added

范例

<?php
$str 
"first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo 
$first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz

parse_str($str$output);
echo 
$output['first'];  // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz

?>
