How to remove the last character of a string if it is "-" ?

 

In replacing some elements in strings, sometimes "-" remains at the end. How to trim the string by removing "-", if it is at the end of the string?

str_replace("~", "", $string)

this should work

function trimdash($string){
if($string{strlen($string)-1} == '-'){
$string = substr($string,0,-1);
}
return $string;
}

Use rtrim()

<?php
$test = 'string with-';
echo rtrim($test,'-');
?>
