PHP Snippet: Display Last X Characters of a URL

Had a request to return the last 23 characters of a url. I am WAY not a coder, but was able to help modify this function to work. Of course, you probably won’t just want to echo the output, but use it as a variable for something else. 

<?php function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
 $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
 $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
 }
 echo substr(curpageURL(),-23);?>

Solving FTP Deletion Error “550 Prohibited file name”

Trying to delete a file via FTP and unable to? Getting a “550 Prohibited file name” error? Annoying! But also very easy to fix. Create a php file called “unlink.php” with this code, replacing the “YOUR-FILENAME-HERE” with–what else?–your undeleteable file name. 

<?php unlink('YOUR-FILENAME-HERE');?>

Upload it to the directory with the file in question, and visit the script in your web browser. It will remove the previously unruly file. ((Thanks to irasmith’s forum post for this solution.))

PHP noobs, please remember to have NO blank spaces before or after the beginning of your code in PHP files, or you’re liable to get a “Cannot modify header information/Headers already sent” error. You can create the file in a text program and simply rename it with a .php extension.
