PHP HTTP上下文选项
介绍
下面给出的是 http：//和https：//传输的上下文选项列表
以下示例从http：//URL获取标头和内容
示例
<?php
$url = "http://localhost/testscript.php";
$opts = array('http' =>
array(
'method' => 'GET',
'max_redirects' => '0',
'ignore_errors' => '1'
);
$context = stream_context_create($opts);
$stream = fopen($url, 'r', false, $context);
var_dump(stream_get_meta_data($stream));
?>输出结果
这将显示标题信息和元数据，如下所示-
