Question

My goal is to put some numeric text in a text box, for example, if I entered “3”, it will come out:

Hello 1

Hello 2

Hello 3

My problem is that it keeps going until the loop entirely finishes (well 74 times), and not adhere to the entered value, and stop at 3 or some digit that I enter.

<div class="Container">
        <h2>Hello Page</h2><hr>
        <form>
            <p>Enter a number:</p>
            <input type="text" name="number">
            <input type="submit" value="Enter">
        </form>

        <?php
        $digit = $_GET['number'];

        if (empty($digit))
            $digit= "";
        elseif (!empty($digit)) {

            for ($digit= 1; $digit< 75; $digit++) {
                if ($digit== TRUE) {
                    echo 'Hello ' . $digit. '<br>';

                } elseif ($digit== $digit) {
                    break;
                }
            }
        }
        ?>

    </div>

Answer 1

Your $digit variable is the maximum, use it that way.
Change your for loop in this

for ($x= 1; $x <= $digit; $x++) {
    echo 'Hello ' . $x. '<br />';
}

Then you will get what you want.
