Count occurrences of a character in a String in PHP

Here is another simple example for - for loops. Thsi PHP code shows how to search for a particular character in a String and count the number of occurrences of that character in that string.

<?php
$text="Welcome to PHP";
$searchchar="e";
$count="0"; //zero
for($i="0"; $i<strlen($text); $i=$i+1){
  
    if(substr($text,$i,1)==$searchchar){
          $count=$count+1;
    }
}
echo $count
?>

this will count how many times the character "e" occurs in that text (Welcome to PHP).
