A substr_count() example <?php $text = 'This is a test'; echo strlen($text); // 14 echo substr_count($text, 'is'); // 2 // the string is reduced to 's is a test', so it prints 1 echo substr_count($text, 'is', 3); // the text is reduced to 's i', so it prints 0 echo substr_count($text, 'is', 3, 3); // generates a warning because 5+10 > 14 echo substr_count($text, 'is', 5, 10); // prints only 1, because it doesn't count overlapped subtrings $text2 = 'gcdgcdgcd'; echo substr_count($text2, 'gcdgcd'); ?>
