练习post传值(手写)
<!doctype html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title></head><body><form action="" method="post"> 账号：<input type="text" name="name" value="33703259"> 密码：<input type="password" name="pass" value="123456"> <button>提交登陆</button></form><?php echo '<hr>'; echo $_POST[name]; echo '<hr>'; echo $_POST[pass]; echo '<hr>';?></body></html>
函数自学
<?php//ceil进一取整计算 echo ceil(9.4);//floor舍去一取整计算 echo floor(9.4);//round四舍五入计算 echo round(9.5446); echo round(9.4446);//取数组内最大数 echo max(1, 2, 8, 100);//取数组内最小数 echo min(1, 2, 8, 100);//mt_rand取范围内随机值echo mt_rand(1, 1000);//strtolower字母转小写echo strtolower('WDASDASD');//strtoupper字母转大写echo strtoupper('xzcxzczxc');//md5编码加密echo md5('PHP中文网');//取当前时间echo date(Y年m月d日h时i分s秒);
