I am designing a calendar using PHP, and I want to fill in the lines until I get to number 31. But this does not happen by changing the condition. How can I do this?

<body>

    <table border="1">

        <tbody>

            <?php



            $day=array("sat","sun","mon","tue","wed","thu","fri");



            echo('<th>'.$day[0].'</th>');

            echo('<th>'.$day[1].'</th>');

            echo('<th>'.$day[2].'</th>');

            echo('<th>'.$day[3].'</th>');

            echo('<th>'.$day[4].'</th>');

            echo('<th>'.$day[5].'</th>');

            echo('<th>'.$day[6].'</th>');



            for($i=1;$i<=31;$i){

            echo("<tr>");

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

                echo('<td>'.$i++.'</td>');

            echo("</tr>");



        }



        ?>

    </tbody>

</table>



</body>

My Answer:
To achieve the specific number 31 in the calendar, you need to modify the for loop condition in your PHP code. Currently, you are incrementing the value of $i multiple times within each iteration of the loop, which is causing the loop to run indefinitely.

You can update your for loop condition to check if $i is less than or equal to 31 before incrementing it. Here is the updated code:

php

for($i=1;$i<=31;$i++){

    echo("");

    echo(''.$i.'');

    echo(''.$i++.'');

    echo(''.$i++.'');

    echo(''.$i++.'');

    echo(''.$i++.'');

    echo(''.$i++.'');

    echo(''.$i++.'');

    echo("");

}

With this change, the for loop will run until $i reaches the number 31, and the calendar will be filled with the numbers from 1 to 31.
