php - work with string

Remove Trailing Slash From String PHP

if(substr($string, -1) == '/') {
    $string = substr($string, 0, -1)
}

Alternative way:

$string = rtrim($string, '/');

• ltrim - Strip whitespace (or other characters) from the beginning of a string
• rtrim - Strip whitespace (or other characters) from the end of a string
• trim - Strip whitespace (or other characters) from the beginning and end of a string
