PHP 数组

         // 这里用数字来作为索引
         $myArray = array(2012, 'blue', 5, 'BMW');

         // 这个用关键字作为索引
         $myAssocArray = array('year' => 2012,
                         'colour' => 'blue',
                         'doors' => 5,
                         'make' => 'BMW');

         // This code will output "blue".
         echo $myArray[1];
         echo '<br />';
         echo $myAssocArray['colour'];
         //循环输出数组结果
         foreach ($myAssocArray as $ingredient=>$include) {
         echo $include . ' ' . $ingredient . '<br />';
       }

         //数组里面有数组
         $deck = array(array('2 of Diamonds', 2),
                       array('5 of Diamonds', 5),
                       array('7 of Diamonds', 7));
             //输出  You have the 7 of Diamonds!
           echo 'You have the ' . $deck[2][0] . '!';
