fopen to specific url path

[soma56]

I'm researching fopen and found this example which works fine:

 

<?php
$filename = 'test.txt';
$somecontent = "Add more to the file\n";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

    // In our example we're opening $filename in append mode.
    // The file pointer is at the bottom of the file hence
    // that's where $somecontent will go when we fwrite() it.
    if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
    }

    // Write $somecontent to our opened file.
    if (fwrite($handle, $somecontent) === FALSE) {
        echo "Cannot write to file ($filename)";
        exit;
    }

    echo "Success, wrote ($somecontent) to file ($filename)";

    fclose($handle);

} else {
    echo "The file $filename is not writable";
}
?>

 

However, when I attempt to write to a specific domain path it doesn't work:

 

$filename = 'http://www.myodmain.com/php/test.txt';

 

I've chmod the file to make it writable - just curious as to what the cause could be.

You can't write to the interwebs.

Thank you - just needed to hear it to make sure.
