How to check remote file...

[sree]

Hi,


i want to check whether a file from remote server is existed or
not.

The file_exists() checks for local server only. But i want a function
that checks the remote server.


If anyone knows please help..

thanks in advance...

Actually, starting at PHP5 it will work on some url's.

But i want a function
that checks the remote server.

I'm not sure exactly how. You could possibly use fsockopen en send a HTTP HEAD
request, and check the response. There may be better options in curl available.

This will do the trick:

if(@fopen($url, "rb")) {
}

Hi,

No probs. I got the solution for this.

that is,

<?php
$TheImage = "http://www.uk-present.co.uk/images/logo.gif";
if (@fclose(@fopen ("$TheImage" , "r"))) {
$TheImage = "$TheImage" ;
}
else {
$TheImage = "http://www.uk-present.co.uk/images/120x60-noimage.gif";
}
?>

The first if loop tells you that the image exist, else it does not
exist



However it works only when the server gives you 404 error

You shouldn't call fclose() on a file handle which never opened. It's
an error - which you're hiding with the @. But the error still occurs,
is still logged and still takes system resources to handle. Better would be:

<?php
$TheImage = "http://www.uk-present.co.uk/images/logo.gif";
if (($fh = fopen("$TheImag e", "r"))) {
$TheImage = "$TheImage" ;
fclose($fh);
}
else {
$TheImage = "http://www.uk-present.co.uk/images/120x60-noimage.gif";
}
?>

Generally, if you have to use '@' you should look at why you need to use it.

Call stream_get_meta _data() on the file handle returned and parse the
wrapper_data array. That contains the HTTP response header, with the
status code in first element.
