How to get String Length in PHP

John on December 09, 2020

You can get the length of a string in PHP using the built-in strlen() utility. It takes one required argument, a string, and returns its length.

Let's try this out on a couple of strings and see what the output is.

$str = 'text';

$result = strlen($str);

dd($result);

4

If the string is empty 0 will be returned by strlen().

$str = '';

$result = strlen($str);

dd($result);

0

Note - if anything other than a string is supplied an exception will be thrown.

Conclusion

You now know how to use the strlen() utility to get string lengths in PHP.
