We will demonstrate the regular expression to count the total number of occurrences of a specified substring within the string using the preg_match_all() function.
<?php
$str = "India is a country located in asia";
$pattern = "/in/i";
$count = preg_match_all($pattern, $str);
printf("Total occurrences of are: %d", $count);
?>
