How to replace all last occurrence of specific character of a string? for example if I want to replace all the characters (say "-") from the end of a sentence?

eg. "Hello world--- This is me----"

I only need the end all "-" characters to be removed, so string will finally be just

"Hello world--- This is me"

Is there a php function like trim() or please suggest how can I do this?

You may use the "rtrim" for this purpose.

$mytext = "Hello world--- This is me----";

echo rtrim($mytext,"-");

This will replace all the occurrence of the said character to the right end of the string.

Please try preg_replace('/-*$/', '', $var);
