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

Removing Specific Characters at String End in PHP

One common task in string manipulation is removing specific characters from the end of a string. For instance, you may need to delete a period if it's the final character.

Let's consider an example:

$string = "something here.";
$output = "something here";

Solution Using rtrim

To remove a specific character from the end of a string, you can use the rtrim function. This function removes any trailing characters specified in its second argument from the input string.

In the given example, to remove a period from the end of the string, you can use:

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

This operation would assign the trimmed string to the $output variable, resulting in:

$output = 'something here';
