PHP循环...需要一些建议

Question

I have the following code:

$q1 = $_POST["q1"];
$q2 = $_POST["q2"];
$q3 = $_POST["q3"];
$q4 = $_POST["q4"];
$q5 = $_POST["q5"];
$q6 = $_POST["q6"];
$q7 = $_POST["q7"];
$q8 = $_POST["q8"];

At the moment, this is hard coded and I need to manually change it each time, I'd like to use variables instead so that it's not a manual process.

Is it a case of using a loop, while or foreach?

If I had the the information $q and q in an array would that help?

Thanks,

Homer.

Answer 1

Consider adjusting your forms to use Array notation, e.g.

<ul>
    <li><input name="q[]" /></li>
    <li><input name="q[]" /></li>
    <li><input name="q[]" /></li>
    <li><input name="q[]" /></li>
    ...
</ul>

This would make $_POST['q'] contain an array with all input values given for 'q', which you can then easily iterate over with foreach like this:

foreach($_POST['q'] as $q) {
    // do something with $q
}
