【散分】exit()与die的区别
1、关于exit()与die的本质区别是什么?
2、你在平时编码或项目中调试时经常用到哪个?
3、用exit()或die是为方便还是其他原因?
各位说说吧!
顺便散点分!
------解决方案--------------------
手册说的很清楚了把
die — 等同于 exit()
------解决方案--------------------
都是中断没啥区别吧,顺便接分
------解决方案--------------------
die() 函数输出一条消息,并退出当前脚本。
该函数是 exit() 函数的别名。
这无意义的事情为何要纠结
------解决方案--------------------
用exit(),die()看着难听~~
结贴给分吧~~
------解决方案--------------------
一般用exit(),die偶尔用用,实质区别还没深究。
------解决方案--------------------
die() 函数输出一条消息,并退出当前脚本。
该函数是 exit() 函数的别名。
如果 status 是字符串,则该函数会在退出前输出字符串。
如果 status 是整数,这个值会被用作退出状态。退出状态的值在 0 至 254 之间。退出状态 255 由 PHP 保留,不会被使用。状态 0 用于成功地终止程序。
如果 PHP 的版本号大于等于 4.2.0,那么在 status 是整数的情况下,不会输出该参数。

结吧,我是来接分的。其实我也不知道,新手路过。
------解决方案--------------------
exit 和 die 是一样的
exit 是从 c 言中沿袭的,die 是 php 特有的
php 建议你使用 die,但是 php 手册的编撰者把他们弄反了
把 exit 是 die 的同义词,变成了 die 是 exit 的同义词
主次颠倒了,使人感到 die 可有可无的样子
其实不然。
php 业者中有不少是 asp 转行过来的,exit 在 vbs 中是跳出循环的指令,而不是终止程序
继续沿用 exit 不利于这批人对 php 的认同
------解决方案--------------------
楼上正解哦~~~~~~~~~
------解决方案--------------------
来接个分吧

徐版主威武!
------解决方案--------------------
一增用exit习惯了
------解决方案--------------------
接分赶紧结帐

------解决方案--------------------
别名,没区别

我比较惯用die

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
