How to find number of characters in a string in PHP

Use the PHP strlen() function

You can simply use the PHP strlen() function to find the number of characters in a string of text. It also includes the white spaces inside the specified string.

Let's take a look at the following example to understand how it basically works:

<?php
$my_str1 = 'The quick brown fox jumps over the lazy dog.';
echo strlen($my_str1); // Outputs: 44
 
$my_str2 = '    The quick brown fox jumps over the lazy dog. ';
echo strlen($my_str2); // Outputs: 49
?>
