你没确定脚本有问题?
单独跑脚本确定没问题?
先确定脚本的问题吧。
报错误不一定是内存不够用,可能是你逻辑问题,给你多少内存都会崩。
你这是死循环 改其他方案
file_put_contents函数是一直占用内存的
用linux的定时任务去执行php脚本
使用sleep(2)
,将程序休息几秒钟
我用的oracle job 存储过程,只不过频率低. 或者在使用订单时条件触发.毕竟只有使用时才需要考虑是否有效
用nodejs来跑
了解到你的目的是:能够自动关闭超时未支付的订单
可以试着换个思路来解决:
把定时任务改为: 每次用户点击订单相关页面时,检测下是否有超时未支付的订单。如果有,则将它们关闭。
crontab
拆分放到任务队列执行
1.你需要把程序改成php-cli方式运行,即试用php命令来执行。例如:/usr/local/php/bin/php index.php
2.把脚本里面while循环更改掉,试用crontab来执行该脚本,当php脚本执行完后,整个php脚本的运行内存就被回收就不会出现内存溢出的问题了。

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
