<?php
$items = array (
    'item1' => array('1001', 'Apple', 'Red Apple', 18),
    'item2' => array('1002', 'Orange', 'Sweet Orange', 17),
    'item3' => array('1003', 'Strawberry', 'Class A Strawberry', 30),
    'item4' => array('1004', 'Mango', 'Yellow Mango', 20),
);

echo '<form method = "post" action = "" class = "df">';
echo '<table width = "800" border = "0">';
echo '<tr>';
echo '<th width = "500" align = "center">ID</th>
      <th width = "500" align = "center">Name</th>
      <th width = "500" align = "center">Description</th>
      <th width = "500" align = "center">Price</th>
      <th width = "500" align = "center">ADD</th>
      ';
echo '<tr>';

foreach ($items as $item){
    foreach ($item as $s1){
        echo '<td height="30" width = "90" align = "center">'.$s1.'</td>';
    }
    echo '<td align = "center" ><input type="checkbox" name="checked[]" value="ch_'. $item[0] .'" id="checkbox"/> Check me out</td>';
    echo '</tr>';
}
echo '</table><br>';

echo '<input type="submit" name="button" id="button" value="Submit" class="sub"/>';

    if ($_SERVER['REQUEST_METHOD'] == 'POST') {
        $checked = @$_POST['checked'];
        if (is_array($checked)) {
            foreach ($checked as $item) {
                $itemId = substr($item, 3);
                $key = 'item' . $itemId;
                print_r($items[$key]);
                echo "<br />checked item $itemId";

            }
        }
    }
