给数组增加元素_PHP

---

 $Cities[] = "北京"; //等同于$Cities[0] = "北京"
 $Cities[] = "天津"; //等同于$Cities[1] = "天津"
 $Cities[] = "上海"; //等同于$Cities[2] = "上海"
 $Cities[] = "深圳"; //等同于$Cities[3] = "深圳"
 /*
 ** 统计元素个数
 */
 $indexLimit = count($Cities); //把数组中元素的个数赋给$indexLimit
 /*
 ** 打印所有数组
 */
 for($index=0; $index  {
  print("第 $index 个城市是 $Cities[$index]。
\n");
 }
