The PHP STRLEN Function: Getting the PHP String Length

Have you ever needed to get the length of a string? PHP makes the process of getting string length easy with the PHP STRLEN (PHP string length) function. Today, we’re going to look at the PHP STRLEN function, when you would use it, and what other functions you might need to use to manipulate strings in PHP.

What is the PHP string length Function?

In PHP, the STRLEN function will simply return the length of a string. PHP strings, like most code strings, are really arrays. So, the PHP string “Hello, World!” is an array of 13 characters, starting with the number 0. The built-in function PHP STRLEN returns the number of characters in the string.

The following code:

<?PHP
	print(strlen("Hello, world!"));
	?>

Will return the following result:

	13

So, you use STRLEN any time you need the length of a string. The STRLEN string can also pass as a variable:

	<?PHP
		$hello = "Hello, world!";
		print(strlen($hello));
	?>

And since the PHP STRLEN function has a function return and returns the number, you don’t need to print the STRLEN. You could also save the number of characters to a variable, like so:

<?PHP
		$hello = "Hello, world!";
		$string_length = strlen($hello);
	?>

This doesn’t print anything, but it does store the STRLEN string’s length into the variable $string_length for use later.
