1. Check if String Ends with Punctuation

In this example, we will take a string, “Hello World!”, in $string variable. We will get the last character using $string[-1]. We shall then pass this last character as argument to ctype_punct() function. We can use the ctype_punct() as a condition in PHP If statement. If ctype_punct() returns true, then our string ends with punctuation.

PHP Program

<?php
$string = "Hello World!";
$lastchar = $string[-1];
if ( ctype_punct($lastchar) ) {
    echo "\"{$string}\" ends with punctuation.";
} else {
    echo "\"{$string}\" does not end with punctuation.";
}
?>
