如何将字符串作为查询读取,就像转到https://www.youtube.com/get_vide_info?v= {{video_id}}
一样它将提供一个信息作为查询(如果你把它放在$ _GET中),PHP将手动读取它!
如果没有在$ _GET中传递它,如果有一个函数
,我怎么能读它示例:
<?php
$s = file_get_contents('https://www.youtube.com/get_vide_info?v={{video_id}}');
// for example it returned status=failed&error=404&reason=copyright
//how can read status and error and reason
// for example
echo "reject reason $s->reason ";
echo "status $s->status ";

一个简单的选择是使用parse_str()
,你可以将其作为数组访问,如果你想作为对象,你必须将它转换为对象。
// arg1 => query string
// arg2 => output array
parse_str($your_string_response, $output);
echo $output['reason'];
echo $output['status'];
测试结果:
$ cat test.php
<?php
$string = "status=failed&error=404&reason=copyright";
parse_str($string, $output);
print_r($output); // as array
print_r((object)$output); // as object
?>
输出:
$ php test.php
Array
(
[status] => failed
[error] => 404
[reason] => copyright
)
stdClass Object
(
[status] => failed
[error] => 404
[reason] => copyright
)

你可以用魔术字段$ _GET ['NameOfQuery']读取queryString;
$s=array("status"=>$_GET['status'],
"error"=>$_GET['error'],
"reason"=>$_GET['reason']);
// out
echo "reject reason:".$s['reason'];
echo "status :".$s['status'];
echo "error :".$s['error'];;
