There are three functions in PHP that can remove the first and last characters of a string: The
trim() function removes blank characters or other predefined characters on both sides of the string.
ltrim() - Removes whitespace characters or other predefined characters on the left side of a string.
rtrim() - Removes whitespace characters or other predefined characters on the right side of the string.

<?php $str = "Hello World!"; echo $str . "<br>"; echo trim($str,"Hed!"); ?>
Remove the characters on the right side of the string:
<?php $str = "Hello World!"; echo $str . "<br>"; echo rtrim($str,"World!"); ?>
