The basic syntax of the strrchr() function is given with:

strrchr(string, char);

The following example shows the strrchr() function in action.

Warning: Prior to PHP 8.0, if char is not a string, it is converted to an integer and applied as the ASCII value of that number. This behavior has been deprecated since PHP 7.3.0, and no longer supported since PHP 8.0. Therefore, don't rely on it.
