PHP rtrim “.php”

Question

I want to remove \".php\" from the end of a string if it exists. Consider this:

$filename = \'index\';
rtrim($filename,\".php\");//returns \"index\"

$filena         


        

Answer 1

if you're simply trying to remove the extension, why not use this: $filename = 'index.php'; $name = strstr($filename, '.', true);

Answer 2

The second argument to rtrim is a string with a list of characters. In this case, it will strip off any P, H, and . in your string, so returning searc.

Answer 3

rtrim accepts a list of characters as the second argument, so in this case, it will trim not just the .php extension, but any ., p, or h characters found in the rest of the string.

Try using preg_replace("/(.+)\.php$/", "$1", $filename); instead, or basename($filename, '.php') if you have the file on the server, not just in a string.
