Write a program which will count the “t” characters in the text “techstudy”

Introduction

PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following example.

<?php
$text="techstudy";
$searchchar="t";
$count="0";
for($x="0"; $x< strlen($text); $x++)
  { 
    if(substr($text,$x,1)==$searchchar)
    {
    $count=$count+1;
     }
  }
echo $count;
?>

Result

Write a program which will count the "t" characters in the text "techstudy"
Write a program which will count the “t” characters in the text “techstudy”
