windows下安装xdebug记录

查看php适合哪个版本

我在这里是踩过坑的，始终不行，确定了php版本，是否线程安全，32位还是64架构，都对上了，但是还是不对。提示如下错误：

[23-Mar-2022 09:24:46 UTC] PHP Warning:  Failed loading Zend extension 'xdebug-3.1.3-7.4-vc15-x86_64' (tried: D:/laragon/bin/php/php-7.4.19-Win32-vc15-x64/ext\xdebug-3.1.3-7.4-vc15-x86_64 (找不到指定的模块。), D:/laragon/bin/php/php-7.4.19-Win32-vc15-x64/ext\php_xdebug-3.1.3-7.4-vc15-x86_64.dll (找不到指定的模块。)) in Unknown on line 0

文件位置及配置都没问题，但是一直报错。

正确的做法是，在命令行输入：

php -i > phpinfo.txt

拿到php的所有信息，然后把上面信息输入到方框中：
​​​https://xdebug.org/wizard​​

结果我这边提示：

瞬间感觉很坑爹，部分版本由于缺少组件，不能支持。。。

于是，我们需要换个版本的php。

下载8.1版本和7.4.28版本，都下下来试试。

安装配置xdebug

换了版本以后，提示就很明晰拿了，需要下载那个版本的xdebug，怎么配置。
