        $i++;
       }
     } while($i<=60);

* Exercise.

1)Write any program using if condition with for loop.

  <?php
    for($i=0;$i<=60;$i++)
    {
        if($i%2==0){
            echo $i,"<br>";
        }
    }
    ?>


2)Write a program to display pyramids of star/patterns using increment/decrement.

    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Star Pattern </title>
    </head>
    <body>
    <?php
       
        $size = 5;
        for($i = 0; $i < $size; $i++) {
           
            for($j = 0; $j <= $i; $j++) {
                echo "*";
            }
            echo "<br>";
        }

* Practical Related Questions.

1)When for loop will be terminated?
Ans => 1) When the break statement is encountered inside a loop, the loop is immediately terminated, and the program control resumes at the next statement following the loop
             
2) Difference between for and for-each loop
Ans=>             for                                                      for each 
         1)   The iteration is clearly visible            The iteration is hidden.

         2) Good Performance                                Better Performance

        3) Stop condition is specify                        stop condition has to be explicitly specify
