Variable in a Variable ?

[Dragomancer]

Hi,
I'm currently working with a html-form, and I've got a lot of variables to work through. Because the form is generated dynamicly, I don't know how many variables I'll get. My code is looking like this:

PHP Code:

if($test1==1){
 ...}
if($test2==1){
 ...}
if($test3==1){
 ...}
if($test4==1){
 ...}
if($test5==1){
 ...} 


Could someone please help by tell me how to combine '$test' into a "double" variable, so it would somehow look like this:

PHP Code:

$count=1;
while(isset($test$count)){
 if ($test$count==1){
  ....
 }
 $count++;
} 


Thanks for your help.

If your talking about arrays, this is what you would do -

$test[$count]

If your talking about combining the string, this is what you would do -

$another_variable = ($test).($count)

Hope that helped.

PHP Code:

$count=1;
while(isset(${"test".$count})){
 if (${"test".$count}==1){
  ....
 }
 $count++;
}

Since it's a POSTed form, you can also use the $_POST array ($HTTP_POST_VARS for older PHP versions).

PHP Code:

foreach ($_POST as $variable => $value) {
    // $variable would be 'test1', 'test2', 'test3', 'test4' etc.
    // And $value would be whatever the user entered in the form
} 


Use print_r() to see exactly what the $_POST array contains, and see how it can be useful:

PHP Code:

print_r($_POST);
