Mac系统 Visual Studio Code PHP7 xDebug 调试配置

一直没用过xDebug，习惯于用echo、log调试好多年。
今日研究Laravel，了解其原理、设计模式后，依旧看不懂调用顺序，所以还是装个xDebug，用单步跟一下来进一步了解。

一、mac系统，直接brew安装

Molsen$ brew install homebrew/php/php71-xdebug

安装后提示：

To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php71/homebrew.mxcl.php71.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php71.plist
...
brew services start homebrew/php/php71

// 看下版本
Molsen$ php -v
PHP 7.1.11 (cli) (built: Oct 27 2017 11:00:43) ( NTS )

// 看下 php.ini 文件的位置
Molsen$ php -i | grep php.ini
Cannot load Xdebug - it was already loaded
Configuration File (php.ini) Path => /usr/local/etc/php/7.1
Loaded Configuration File => /usr/local/etc/php/7.1/php.ini

// 查看xdebug安装目录
Molsen$ cat /usr/local/etc/php/7.1/conf.d/ext-xdebug.ini
[xdebug]
zend_extension="/usr/local/opt/php71-xdebug/xdebug.so"

// 编辑php.ini，增加配置
Molsen$ vim /usr/local/etc/php/7.1/php.ini

php.ini 增加以下配置

zend_extension="/usr/local/opt/php71-xdebug/xdebug.so"
xdebug.profiler_enable = on
xdebug.trace_output_dir = "/data/logs/xdebug"
xdebug.profile_output_dir = "/data/logs/xdebug"
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_host = "localhost"
xdebug.remote_port = 9000
xdebug.idekey = "phpStorm"

保存并退出，重启php-fpm brew services restart homebrew/php/php71

// 查看 xdebug 的php扩展是否安装成功
Molsen$ php -i |grep xdebug
Cannot load Xdebug - it was already loaded
/usr/local/etc/php/7.1/conf.d/ext-xdebug.ini
xdebug
xdebug support => enabled
...
// 能看到这些就是装好了

二、VS Code 配置

1. 安装 PHP Debug 扩展
2. 左侧调试按钮 - 左侧顶部调试[Listen for XDebug]，设置

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9000
        }
    ]
}

查看9000端口的监听情况

Molsen$ lsof -i:9000
COMMAND     PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
php-fpm   70380 Molsen    6u  IPv4 0xc7008b2dba54edf9      0t0  TCP localhost:cslistener (LISTEN)
php-fpm   70383 Molsen    0u  IPv4 0xc7008b2dba54edf9      0t0  TCP localhost:cslistener (LISTEN)

我是在配置 Visual Studio Code 多次失败的情况下，已经放弃了它，然后转向配置phpstrom的时候，突然发现VS Code已经可以用了。。。没找到原因。
