<form action="#" method="post">
<input type="checkbox" name="box[]" value="C/C++"><label>C/C++</label><br/>
<input type="checkbox" name="box[]" value="Java"><label>Java</label><br/>
<input type="checkbox" name="box[]" value="PHP"><label>PHP</label><br/>
<input type="submit" name="submit" value="Submit"/>
</form>

I am using php code to fetch checked box values, how can I save each checked values in different variable out of loop?

<?php
if(isset($_POST['submit'])){
    if(!empty($_POST['box'])){

        foreach($_POST['box'] as $selected){
            echo $selected."</br>";
        }
    }
}
?>

Where and why you save it depends upon what you want to do with it later! – RiggsFolly Oct 01 '16 at 22:21
Because i have to pass theme on mail function – Tauqeer Oct 01 '16 at 22:21

So use POST data itself, why to create so many variables? – Alive to die - Anant Oct 01 '16 at 22:21
@Anant now thats an inteligent suggestion at last – RiggsFolly Oct 01 '16 at 22:22

`if(!empty($_POST['box']))` use `isset()` for checkboxes. – Funk Forty Niner Oct 01 '16 at 22:22

The point @Fred-ii- is making is that UNCHECKED checkboxes are not actually passed to the PHP script, so you should not assume that any of them are actually in $_POST – RiggsFolly Oct 01 '16 at 22:24
@Anant through that method i just get the last selected value not all,i have tried that one. – Tauqeer Oct 01 '16 at 22:24
@Anant Nope; it should get the values from the selected checked inputs. Edit: unless they pass a key value. – Funk Forty Niner Oct 01 '16 at 22:26
When PHP fills and gives you $_POST its all yours. Why do people thinks they must move $_POST values into other locations. Use $_POST as it is, its all yours to do with as you like. You can even add to it, for the suration of the script you are running – RiggsFolly Oct 01 '16 at 22:28
@Anant ONLY if the checkbox is checked, so it could be completely MISSING from $_POST if non of the checkboxes are checked – RiggsFolly Oct 01 '16 at 22:29

@Tauqeer please make yourself clear by some expected outcome? that will help you and us.At-least i am not clear about what you are trying to achieve (meanwhile in conversation it's confusing to me) – Alive to die - Anant Oct 01 '16 at 22:36
