Question

How to set a = 0 value for each checkbox unchecked

Error:

Warning: array_combine() [function.array-combine]: Both parameters should have an equal number of elements in

PHP:

$combined = array_combine($_POST['name'], $_POST['day']);

foreach($combined as $name => $value) {
     echo $name.' => '.$value;
}

HTML:

  <form method="post" action="result.php">
  <p>
        <input type="text" name="name[]" value="seth" />
        <input type="checkbox" name="day[]" value="7" />
  </p>

  <p>
        <input type="text" name="name[]" value="jack" />
        <input type="checkbox" name="day[]" value="4" />
  </p>

  <p>
        <input type="text" name="name[]" value="david" />
        <input type="checkbox" name="day[]" value="3" />
  </p>

 </form>

PS:
I won’t use:

        <select name="day[]" size="1">
           <option value="0"> Non </option>
           <option value="1"> Yes </option>
        </select>

Here you go. Hope this works for you. It’s a bit more work then what you were hoping for probably.

result.php

<?PHP

$days = array();
$namecount = count($_POST['name']);
for($i = 0; $i < $namecount; $i++){
    $days[$i] = isset($_POST['day'][$i]) ? $_POST['day'][$i] : 0;
}

$arr = array_combine($_POST['name'], $days);
print_r($arr);

?>

form.html

<form method="post" action="result.php">
    <p>
        <input type="text" name="name[]" value="seth" />
        <input type="checkbox" name="day[0]" value="7" />
    </p>

    <p>
        <input type="text" name="name[]" value="jack" />
        <input type="checkbox" name="day[1]" value="4" />
    </p>

    <p>
        <input type="text" name="name[]" value="david" />
        <input type="checkbox" name="day[2]" value="3" />
    </p>
    <input type='submit' value='Submit' />
</form>
