How to Remove a Period from the End of a String in PHP?

Eliminating Specific Characters from a String's Termination in PHP

In PHP, the efficient removal of specific characters at the end of a string is a common task. One scenario commonly encountered is the selective removal of a period (.) at the end of a string. To address this specific issue, let's explore a solution using PHP's built-in functions.

Using rtrim to Remove a Period

To selectively remove a period at the end of a string, the rtrim() function can be utilized. It takes two parameters: the string to be manipulated and the characters to be trimmed from the right end.

Example:

$string = "something here.";
$output = rtrim($string, '.');

// Result: $output = 'something here'

By invoking rtrim() with the string and '.' as arguments, any trailing periods in the string are eliminated, leaving behind the desired output.
