$cookie = $_COOKIE['name'];//接收指定cookie
$header = 'test=';
//没有找到指定的内容
if( strpos($cookie,$header) === false){
echo '我不知道';
//重新设置过期时间
$_COOKIE('name',值,过期时间);
}
$cookie = $_COOKIE['name'];//接收指定cookie
$header = 'test=';
//没有找到指定的内容
if( strpos($cookie,$header) === false){
echo '我不知道';
//重新设置过期时间
$_COOKIE('name',值,过期时间);
}
这里的cookie不指定怎么做?上面JS的cookie就是打开浏览器有cookie而已 不需要值
凡事都有个度,php 不能代替 js 完成的工作
你的那段 js 代码完成的是这样的工作:如果名为 test 的 cookie 变量不存在,则创建他
等价的 php 代码是 if(! isset($_COOKIE['test'])) setcookie('test', 'yes', time()+60);
但是 js 是运行于 2 次 php 之间的,于是效果也是不一样的

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.
