c++ - 如何查看php内核的调度顺序,不想每次编译然后看看是否执行了自己想要的分支

Jun 06, 2016 pm 08:19 PM
c c++ php

问题是这样的,我想调试一下看看php内核的具体文件调用,大体的调用结构自己大概也知道了,但是具体的不知道如何方便的调试

我目前所用的方法就是手动的去php_printf一些信息,然后重新编译php来看看是否走到了这一步,但是这样每次花好长时间重新编译。

所以想问大家有没有好的办法可以调试!

编译 phpconfigure 中添加 --enable-debug 即可打开 php 调试模式,这时候编译的 php 是带有调试信息的,可以通过 gdb 进行断点调试。不知道这样能不能满足你的需求?

不知道你使用的是什么IDE,我只是介绍一下我的经验。我开发PHP扩展使用 CLion ,使用 debug 模式的 php ,在 Clion 中直接使用 gcc 编译扩展运行,断点可以直接在编译器中打,调试运行、步进都正常使用。如果 php 的源码仍然保留着,可以把断点直接打到源码中。编译到开始调试一步完成。

C# vs. C  : History, Evolution, and Future Prospects C# vs. C : History, Evolution, and Future Prospects Apr 19, 2025 am 12:07 AM

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.
