jquery array push to php foreach

I'm getting this error in php:

Invalid argument supplied for foreach()

I am tring to create an array in jquery for the input values

<input type="text" class="passenger">
<input type="text" class="passenger">
<input type="text" class="passenger">

Then the js is :

var passengers = new Array();

$('.passenger').each(function(){
    if($(this).val() == " "){
        passengers.push(JSON.stringify($(this).val()));
    }
});

Then after i post it to php, i am wanting it so i displays all the passengers

at the moment, this is not working. Why not

foreach($passengers as $pass){
    $each_passengers = json_decode($pass);
}

Actually you don't need to stringify each input. What you need to do first, is create a grouping name attribute in your form inputs:

<input type="text" name="input[]" class="passenger" value="test1" />
<input type="text" name="input[]" class="passenger" value="test2" />
<input type="text" name="input[]" class="passenger" value="test3" />

Then, in your $.post(). Just feed them as serialized using $(form).serialize():

$.post('myphp_process.php', $('#form_values').serialize(), function(response){

Then of course the PHP that will process it, just treat it as normal POST:

$inputs = $_POST['input']; // this will return an array of inputs and to access this you need a loop.

// for clarity print_r($_POST['input']);

Check this out. This should give you the basic idea.
