请问:mysql数据库有个游标吗
大哥, 我想做个PHP文件, 访问一次这个PHP文件, 从数据库取一条记录, 第二次访问, 取下一条,

如何才能实现呢?游标怎么用法,?不太会写SQL语句.  谢谢了
------解决方案--------------------

引用:
改了所有的PHP.INI,  重启服务,  还有一样错误, 奇怪了, 
我先试试将变量保存于数据库、文件、共享内存等中, 不知道哪个简单 些


那就是你服务器没有配置好了,如果先测试,可以把变量写文件吧。

$file='session.txt';
if(!file_exists($file)){
    $cursor = 0;
    file_put_contents($file, 0, true);
}else{
    $cursor = file_get_contents($file);
    $cursor ++;
    file_put_contents($file, $cursor, true);
}
  
$query="select id,title,email from cmsecms_custinfo where LIMIT $cursor, 1";
$sql=$empire->query($query);

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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: Identifying and Fixing BottlenecksPHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

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.
