#Loops

<?php
    #loops execute code a set number of times
    /*
    Types of loops
    1-For
    2-While
    3-Do..while
    4 Foreach
    */

    # For Loop usually use if you know the number of times it has to execute
    # @params -it takes an init, condition, increment
    #for($i =0;$i<=11;$i++){
    #echo 'Number: '.$i;
    #echo '<br>';
    #}
    #While loop
    # @ prams - condition
    #$i = 0;
    #while($i < 10){
    #    echo $i;
    #    echo '<br>';
    #    $i++;
    #}
    # Do...while loops
    #@prapms - condition
    /*$i = 0;
    do{
        echo $i;
        echo '<br>';
        $i++;
        }
        while($i < 10);*/
    # Foreach  --- is for arrays
    
    # $people = array('Brad', 'Jose', 'William');
    #     foreach($people as $person){
    #     echo $person;
    #     echo '<br>';
    # }
    $people = array('Tony' => '[email protected]',
        'Jose' => '[email protected]','William' => '[email protected]');

    $b = 0;
 for( $i = 0; $i<5; $i++ )
    {
        $a += 10;
        $b += 5;
    }    
echo ("At the end of the loop a = $a and b = $b" );
?>
//.......................................//
  do {
   code to be executed;
}
while (condition);
//Example
<?php
     $i = 0;
    $num = 0;
         
  do {

3 * @ParamConverter("program", class="App\Entity\Program", options={"mapping": {"program_id": "id"}})
4 * @ParamConverter("comment", class="App\Entity\Comment", options={"mapping": {"comment_id": "id"}})
5 */
6public function showProgramComment(Program $program, Comment $comment): Response
7{
8  return $this->render('comment.html.twig', [
