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 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 $len;
?>
<?php// PHP program to count all// characters in a string$str = "GeeksforGeekslover"; // Using strlen() function to// get the length of string$len = strlen($str);// Printing the resultecho $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 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);
?>
<?php// PHP program to find the length of// a given string which has special// characters$str = "\n LuckyGeeks ;"; // Here '\n' has been counted as 1echo strlen($str);?>Output:
14
