In this article, we will see how to get the length of the string using strlen() function in PHP, along with understanding its implementation through the examples.
The strlen() is a built-in function in PHP which returns the length of a given string. It takes a string as a parameter and returns its length. It calculates the length of the string including all the whitespaces and special characters.
Syntax:
strlen($string);
Parameters: The strlen() function accepts only one parameter $string which is mandatory. This parameter represents the string whose length is needed to be returned.
Return Value: The function returns the length of the $string including all the whitespaces and special characters.
Below programs illustrate the strlen() function in PHP:
Example 1: The below example demonstrates the use of the strlen() function in PHP.
PHP
<?php // PHP program to find the // length of a given string $str = "neveropen"; // prints the length of the string // including the space echo strlen($str);?> |
Output:
13
Example 2: This example demonstrates the use of the strlen() function 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 $str = "\n neveropen Learning;"; // here '\n' has been counted as 1 echo strlen($str);?> |
Output:
25
