新手,刚接触php,麻烦各位大神了

Customer:

Product | Unit Price | Quantity Ordered | Item Cost |
---|---|---|---|
Unpopped Popcorn | $3:00 | ||
Caramel Popcorn | $3:50 | ||
Caramel Nut Popcorn | $4:50 | ||
Toffey Nut Popcorn | $5:00 | ||
Unpopped Popcorn | $3:00 |
print("You odered $total_items popcorn items

printf("Your total bill is:$ %5.2f

print("Your chosen method of payment is:$payment

回复讨论(解决方案)
500是个内部错误...原因多面. 换个apache 吧
这代码错误
这是什么东东?
$unpop=$_post["unpop"];
$caramel=$_post["caramel"];
$caramelnut=$_post["caramelnut"];
$toffeynut=$_post["toffeynut"];
$name=$_post["name"];
$street=$_post["street"];
$city=$_post["city"];
$payment=$_post["payment"];
你们都没看到这段代码会报未定义变量警告吗?
如果未开启错误显示,那自然就是 500 错了
$_post 应写作 $_POST
嗯嗯,POST要大写。
一楼:apache没有问题的,刚刚写了另外一个表单的的代码,能够正常运行。
至于二楼和三楼:你们说的这段代码原本是调试用的,没有成功,就被注销了。但是没有被删除
POST,大写之后,还是有错误
在浏览中直接运行当然不行,你得要提交
php.ini 中令 display_errors=On ,然后重启服务器再运行看看。
改了之后,apache,浏览器重启还是这样的。郁闷。。。我的apache版本比较低,难道是版本的问题。但是这个代码就行得通
//if ($Submit=="提交") {
$username=$_POST[username];
$password=$_POST[password];
//}
?>

刚刚又试下就好了。不知道是什么原因,可能还是改php.in后好的,display_errors=On有什么用了?是错误能够显示在浏览器上面吗?
对!错误能够显示在浏览器上

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
