作业

  1. <?php
  2. //定义数组
  3. $filename = ['QQ','PS','webchat'];
  4. ?>
  5. <ol>
  6. <!--开始遍历循环输出数组-->
  7. <?php foreach ($filename as $softname): ?>
  8. <li><?php echo $softname ?></li>
  9. <?php endforeach ?>
  10. </ol>

PS:PHP遍历数组是把数组的多个值通过FOREACH函数给遍历循环输出出来。
刚进班级,之前的JS还没有学习,所有只做了今天学的PHP中的遍历数组。

运行结果如下


课堂笔记

  1. php指令分隔符;
  2. 1、功能执行语句必须加指令分隔箱
  3. 2、结构定义语句
  4. for 遍历
  5. forEach(JS)
  6. foreach(php)
  7. PHP变量$美元符 =是赋值符号
  8. 1PHP变量的类型是由内容所决定
  9. 2、变量的命令要具有一定的意义
  10. 3、变量命名 多个单词使用驼峰法命名
  11. 输出方式
  12. var_dump();
  13. echo ();
