php foreach loop only display the first letter of array [duplicate]

You did create a single level array, while what you need is a multidimensional array (i.e. an array in an array):

$cs1_array = array();
$cs1_array[] = array(
    'item' => $item,
    'price' => $price
);

Compare this:

// wrong
array(2) {
  ["item"]=>
  string(13) "stackoverflow"
  ["price"]=>
  string(5) "30.00"
}

vs.

// right
array(1) {
  [0]=>
  array(2) {
    ["item"]=>
    string(13) "stackoverflow"
    ["price"]=>
    string(5) "30.00"
  }
}

You don’t need the loop at all if you have only one item and one price in your array:

$item= "stackoverflow";
$price = "30.00";

$cs1_array = array();
$cs1_array['item'] = $item;
$cs1_array['price'] = $price;

    if(sizeof($cs1_array) > 0){
            echo "<table>";
            echo "<tr>";
            echo "<td>{$cs1_array['item']}</td><td>{$cs1_array['price']}</td>";
            echo "</tr>";
            echo "</table>";
    }

However, if you’d like to have multiple instances of item and price, you need an array of arrays:

$cs1_array = array();
$cs1_array[] = array(
    "item" => "stackoverflow",
    "price" => "30.00"
);
$cs1_array[] = array(
    "item" => "superuser",
    "price" => "40.00"
);
$cs1_array[] = array(
    "item" => "serverfault",
    "price" => "20.00"
);
// and so on

As a more concise alternative to the above code, you may create the array and fill it with values in a single statement:

$cs1_array = array(
    array(
        "item" => "stackoverflow",
        "price" => "30.00"
    ),
    array(
        "item" => "superuser",
        "price" => "40.00"
    ),
    array(
        "item" => "serverfault",
        "price" => "20.00"
    ),
    // and so on
);

Then the foreach loop will work correctly:

if(sizeof($cs1_array) > 0){
    echo "<table>";
        foreach($cs1_array as $item){
        echo "<tr>";
        echo "<td>{$item['item']}</td><td>{$item['price']}</td>";
        echo "</tr>";
        }
    echo "</table>";
}
