Evaluating Strings...

[number1.email]

In php, I have an array called "q". The elements are:

$q[0] = 2
$q[1] = 4
$q[2] = 5
$q[3] = 3

I'd like to be able to loop through this array via a While loop, and
echo the contents of these array elements back to the screen.

When I try something like:

for($i = 0; $i < 4; $i++) {
echo $q[i];
echo eval("$q[i]");
echo eval("\$q[" . i . "]");
}

I get the "String" instead of the "Contents". For example, the output
is $q[0] instead of 2, $q[1] instead of 4, etc.

How can I fix this? Thanks.

Use echo $q[$i].

Add this code on top of your script:

error_reporting(E_ALL);

It will warn you that you're using an undefined constant called "i".
