vscode配置php-src源码调试

虚拟机安装PHP

先下载一个Linux镜像，我选择Ubuntu镜像server版

基于上述镜像添加虚拟机，按提示填写地区和用户信息

登录服务器安装远程连接软件

#安装ssh服务
apt install openssh-server
systemctl start ssh
ufw allow 22
#virtual box添加端口映射2222->22

虚拟机添加共享文件夹

D:\VirtualBox VMs\php8.4\share，共享名sharephp840，共享到/home/xiao/share

xiao# sudo mount -t vboxsf sharephp840 ./share
xiao# vim /etc/fstab # 添加 sharephp840 /home/xiao/share vboxsf defaults 0 0

下载php源码拷贝到共享文件夹

tar -zxvf php-8.4.0.tar.gz
sudo apt update
sudo apt install build-essential libxml2-dev libssl-dev libcurl4-openssl-dev libjpeg-dev libpng-dev libfreetype6-dev libzip-dev libsqlite3-dev
./configure --prefix=/home/codes/php/php-8.4.0/output/ --enable-fpm --enable-debug CFLAGS="-g3 -O0"# -g3 保留宏信息，-O0 禁用优化
make
make install

配置vscode

安装Remote-SSH扩展

按住ctrl+shift+p打开命令面板，找到remote-ssh:connect to host…，输入上述虚拟机连接信息，连接成功后打开虚拟机上的PHP源码目录。

在vscode侧边栏，点击run and debug，创建一个launch.json，添加配置信息如下：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug PHP Core",
            "type": "cppdbg",
            "request": "launch",
            "program": "/home/codes/php/php-8.4.0/output/bin/php",
            "args": [
                "/home/xiao/share/php/array.php"
            ],
            "cwd": "/home/xiao/share/php-8.4.0",
            "environment": [],
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

下面就可以在php源码设置断点调试了
