PHP中将查询字符串解析到数据及逆操作

parse_str() 函数把查询字符串解析到变量中

<?php
parse_str("id=23&name=John%20Adams",$myArray);
print_r($myArray);
?>

输出结果：

Array
(
[id] => 23
[name] => John Adams
)

http_build_query 生成 URL-encode 之后的请求字符串

<?php
$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data) . "\n";
echo http_build_query($data, '', '&amp;');

?>

输出结果：

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&baz=boom&cow=milk&php=hypertext+processor
