判断远程文件是否存在代码如下:
排除重定向的实例代码如下:
代码如下:
function get_real_headers($url,$format=0,$follow_redirect=0) {
if (!$follow_redirect) {
//set new default options
$opts = array('http' =>
array('max_redirects'=>1,'ignore_errors'=>1)
);
stream_context_get_default($opts);
}
//get headers
$headers=get_headers($url,$format);
//restore default options
if (isset($opts)) {
$opts = array('http' =>
array('max_redirects'=>20,'ignore_errors'=>0)
);
stream_context_get_default($opts);
}
//return
return $headers;
}
?>
