Reading variable names

[andyg2]

Can I simplify this?

if($name1!=""){
array_push ($stack, array("$name1"=>"$email1"));
}

if($name2!=""){
array_push ($stack, array("$name2"=>"$email2"));
}

etc etc.

The serialised $name and $email variables are posted from a form and may go up as high as $name200 and $email200.

Can a function be written to cycle through the post data?
I think I may be able to solve this if I could get the variable name into a string.

Any help will be appreciated.

If thisis post data you can cycle through the $_POST array

you might want to use a html-php trick

instead of naming your form inputs

<... name="input100" />
<... name="input101" />
<... name="input102" />

you can name them as if they were php arrays, and php will make them into an array for you

<... name="input[]" value="1" />
<... name="input[]" value="2" />
<... name="input[]" value="3" />

will translate into php as

$input = array();
$input[] = "1";
$input[] = "2";
$input[] = "3";

and will show up in the post as

$_POST = array(
    'input' => array(
        0 => "1",
        1 => "2",
        2 => "3",
     )
);

and in that form you can simply

foreach ( $_POST['input] as $value ) {
/// do whatever with value
}

does that make sense, and is that what you were looking to do?

[edit]
P.S.
if the keys are very important you can always just say

<input type="text" name="input[101]" value="0" />

and it will show up as

$input = array( '101' => '0' );

which is exactly what you had cobbled together above.

:eek: You don't know how many problems, past, present and future you have just solved!

Thank you so much!🙂
