How to get String Length in PHP ?

In this article, we learn how to find the length of the string in PHP. 

Approach: This task can be done by using the built-in function strlen() in PHP. This method is used to return the length of the string. It returns a numeric value that represents the length of the given string. 

Syntax:

strlen($string)

Example 1: 

PHP

<?php
// PHP program to count all
// characters in a string
$str = "GeeksforGeekslover";

// Using strlen() function to
// get the length of string
$len = strlen($str);

// Printing the result
echo $len;
?>

Output:

18

Example 2: Below code demonstrates the use of strlen() function in PHP where the string has special characters and escape sequences.

PHP

<?php
// PHP program to find the length of
// a given string which has special
// characters
$str = "\n LuckyGeeks ;";

// Here '\n' has been counted as 1
echo strlen($str);
?>

Output:

14
