无法使用cURL打开本地文件

Question

Hi,

I am using this code:

$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL, SITE_PATH . '../../blog/index.php');
$xml_file = curl_exec($curl_handle);
preg_match("/<title>(.*)<\/title>/i", $xml_file, $matches);
$title= $matches[1];
curl_close($curl_handle);
$title= $matches[1];

This code is supposed to open one local file and search for the title tag to have it as a variable value. But despite no error is displayed I am getting nothing as $title. What could be wrong?

Thank you.

Why not just use existing file handlers for this, such as file_get_contents() or fopen(). cURL is for external HTTP requests, not internal directory requests.

$xml_file = file_get_contents(SITE_PATH . '../../blog/index.php');
preg_match("/<title>(.*)<\/title>/i", $xml_file, $matches);
$title= $matches[1];

Although your path doesn't seem correct. More than likely it's either ../../blog/index.php, or, SITE_PATH .'/blog/index.php'
