echo "<hr>";
//定义数组的多种方法
//方法一
$array=array(&#39;orange&#39;,&#39;apple&#39;,&#39;banana&#39;);
var_dump($array);//打印数组array
//方法二
$array[]=&#39;orange&#39;;
$array[]=&#39;apple&#39;;
var_dump($array);//打印数组array
//方法三
$array=[];//这种不常见，但我觉得很简洁，类似于$array=array();
var_dump($array);//打印数组array
//定义索引数组
//方法四
$array=array(
  &#39;orange&#39;=>12,
  &#39;apple&#39; =>18,
);
var_dump($array);//打印数组array
//方法五
$array[&#39;apple&#39;]=18;
