如何从我的服务器 [PHP] 读取 .txt 文件？

Question

I'm creating a Telegram Bot in PHP. My aim now is read from a .txt file a integer and put him in a variable. This text.txt is uploaded in a server. I tryed to do this:

$filename = "http://<MY HOST NAME>/test_bot/file/text.txt";
$fp = fopen($filename, "r+");
$send = fgets($fp);
fclose($fp);

echo $send;

But when I try to open my index.php, nothing comes out written. am I doing something wrong?

Since you are opening from a remote host you can't open for read/write, just read. Try this instead:

$fp = fopen($filename, "r");

If you are trying to open a file on the same server as the PHP script then do not use the "http://..." path but instead the local file path and then you can open it for read/write. In the case of your script it does not appear you need write access so "r" should be sufficient.

To access without http just use the path to the file:

$filename = '/path/to/file/text.txt';
$fp = fopen($filename, "r+");

Or if you want a relative path from the script itself I prefer:

$filename = dirname(__FILE__) . '/../some/relative/path/text.txt';
