Removing Specific End Characters in PHP

In certain scenarios, it may be necessary to modify the end of a string by removing specific characters. This article addresses the common question of removing all instances of a particular character at the end of a string using PHP.

Removing a Period at the End

Often, the task involves removing the last character only if it is a period (.). For instance, consider the following string:

$string = "something here.";

To remove the period only if it's present, PHP provides the rtrim() function:

$output = rtrim($string, '.');

The rtrim() function removes all instances of the specified character (second argument) from the end of the string ($string). In this case, it will remove the period if it exists. The result is stored in the $output variable:

$output = 'something here';

The modified $output string now contains the original text without the trailing period. This approach can be applied to remove other specific characters at the end of a string using rtrim.
