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 = "zambiateklover"; 
      
// Using strlen() function to 
// get the length of string 
$len = strlen($str); 
  
// Printing the result 
echo $len; 
?> 

Output:

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); 
?>
