VSCode 配置集成 PHP IntelliSense 时报错：Error spawning PHP: Command failed: php --version

我使用 VS Code 进行PHP开发，安装了 PHP IntelliSense 扩展插件，并按照VSCode官方文档的指引设置了PHP的相关参数。

我在 VSCode 的配置文件settings.json中，进行了如下的配置：

{
	"php.executablePath": "E:/xampp/php/php.exe",
	"php.validate.enable": true,
	"php.validate.executablePath": "E:/xampp/php/php.exe",
}

路径配置都是对的，但是在 VSCode 中打开PHP文件时，软件右下角还是提示如下信息：

Fatal error: Unable to start standard module in Unknown on line 0

请问，这种问题该如何解决呢？

根据你给出的错误提示信息，归纳一下，其实就是下面两个错误：

Unable to load dynamic library 'bz2' (tried: \xampp\php\ext\bz2 (找不到指定的模块。), \xampp\php\ext\php_bz2.dll (找不到指定的模块。)) in Unknown on line 0
Cannot open '/xampp/php/extras/browscap.ini' for reading in Unknown on line 0

究其本质，这两个错误其实是同一个错误，就是php.exe无法按照PHP配置文件（php.ini）中指定的路径找到对应的扩展模块和其他配置文件（这里是browscap.ini）。

看得出，你用的就是XAMPP。

这是因为XAMPP中PHP配置文件（php.ini）的许多路径配置都是相对路径，相对的是当前磁盘的根目录：

; 以下是配置的片段
[PHP]
extension_dir = "\xampp\php\ext"

[browscap]
browscap = "\xampp\php\extras\browscap.ini"

你的VSCode安装目录应该不在E盘，所以它执行php.exe时，根目录相对的当前磁盘就不是你的XAMPP所在的E盘，自然就无法正确找到对应的文件。

你可以将上述相对路径配置修改为绝对路径，如以下配置所示：

; 以下是配置的片段
[PHP]
extension_dir = "E:\xampp\php\ext"

[browscap]
browscap = "E:\xampp\php\extras\browscap.ini"
