Hi guys,

I have read many tutorials on eval for php and its just getting any
clearer. Im used to javascript and flash eval.

I have 5 text boxes answer1...answer5 that will be submited to insert
into a
database. When I retreive the form values I would like to put them
into a variable ($answer1,$answer2 ...) like this:


$i++;
//update actions for 5 answers
$sAnswer = eval("$answer".$i);


So I would like $sAnswer to equal and evaluate $answer1...$answer5

I cant seem to figure out how the heck to create the syntax.

Thanks for your help in advanced.

Here is a simple fix...

Change all the textbox names's to something like this answer[1],answer[2],answer[3] etc.

Then change your code to something like

PHP Code:

<?php

while(list($key, $val) = each($answer)) {

 echo "$key - $val<br>";

}

?>

That code will output something like

1 - Answer for Q1
2 - Answer for Q2
