Check if String ends with a Letter in PHP

This tutorial will discuss about a unique way to check if string ends with a letter in PHP.

Suppose we have a string and we want to make sure that string ends with any letter. It can be uppercase correct letter or a lower case letter. For this, we can use the regular expressions.

The regex pattern: ‘/[A-Za-z]$/’, matches string if it ends with a character. This can be capital character from A to Z or a lower case character from a to z. Now we can pass this regular expression in the preg_match() function along with the string. If the string ends with the letter that it will match the given regex pattern and it will return one.

We have created a separate function for this,

function endsWithLetter($str)
{
    return preg_match('/[A-Za-z]$/', $str) === 1;
}

It accepts a string is an argument and returns true if the string ends with the letter today.

Let’s see the complete example,

<?php
/**
 * Checks if a string ends with any letter
 * using regular expressions (preg_match()).
 *
 * @param string $str The string to check.
 * @return bool True if the string ends with any letter, false otherwise.
 */
function endsWithLetter($str)
{
    return preg_match('/[A-Za-z]$/', $str) === 1;
}

$strValue = "Last Coder";

// check if string ends with any letter
if (endsWithLetter($strValue)) {
    echo "The string ends with a letter.";
} else {
    echo "The string does not end with a letter.";
}
?>

Output

The string ends with a letter.
