Writing an unpredictable number of variables into an Array

[adder]

In normal circumstances if I have two variables, I can write them into an array like this

$var1 = 3;
$var2 = 4;
$myarray = array($var1, $var2);

What if I don't know in advance how many variables I will have? Variables are sent via form input from another script with method="POST". I can get 4 variables now but a few minutes later someone else might send 14 variables.

All I really need is to save the variables in an array.

Could you please point me in the right direction?

foreach($_POST as $name => $value) {
print "$name : $value<br>";
}

You can use [] to append to an array:

$myarray = array();
foreach($_POST as $k => $v)
{
 $myarray[] = $v;
}

@dmorison, @StoutFiles great stuff, I didn't know you could do that!

I realised that I can use this function and avoid defining the &_POST variables. It will automatically grab everything that is $_POSTed to this script and write into an array. Brilliant! Thank you very much!
