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] . '!';
