Description

A simple script to add IP addresses to a file called ip.txt - Can be easily expanded, but is mainly used to show how to open files, read from them, and add on to them.

More Info

PSCode may screw up the formatting. If so, just either remove the comments or I'll come by and fix it by uploading, but it's such a small bit of code that I wouldn't want to do that.

<?						// Quick IP log thing for SonicBlue by Davus
ignore_user_abort(1);				// In case the user closes the page first, it won't screw up
$f = fopen("ip.txt", "r");			// Open the file for reading
$l = fread($f, filesize("ip.txt"));		// Read from point 1 to the end (file size)
fclose($f);					// Got the data, enough for that
if (!strstr($l, $_SERVER['REMOTE_ADDR'])) {	// If the IP address is not already there....
$f = fopen("ip.txt", "a");			// Open for append (adds to end of file)
fwrite($f, $_SERVER['REMOTE_ADDR']."\n");	// Write their IP address to the logfile followed by new line
fclose($f); }					// Writing done, save/close the file
