Hello Friends Today, through this tutorial, I will tell you How to Use `substr_count()` function using PHP, PHP 8, PHP 8.1, PHP 8.2 With Example. In PHP, the `substr_count()` function is used to count the number of occurrences of a substring within a string. It has been available since PHP 4 and remains relevant in PHP 8.1 and 8.2. Below is an example demonstrating how to use `substr_count()` in PHP 8.1 and 8.2:
<?php // Example string $string = "Hello, hello, hello, how are you?"; // Substring to count occurrences of $substring = "hello"; // Count the occurrences of the substring in the string $count = substr_count($string, $substring); // Display the count echo "Number of occurrences of '$substring' in the string: $count"; ?>
This script will output:
Number of occurrences of 'hello' in the string: 3
In this example, the `substr_count()` function is used to count the occurrences of the substring “hello” within the string “Hello, hello, hello, how are you?”. It returns the count of occurrences, which is then displayed using `echo`.
