php 链接 clickhouse

一、通过pypclickhouse插件连接ck数据库
　　　博主用的1.1.2因为我们公司使用的php5点几版本，这是最高支持
　　   插件地址：https://github.com/smi2/phpClickHouse/tree/e27b04d482e9922df8bf1ea0880bf2985d2e06d0
　　
 
使用默认配置去连接 clickhouse
错误：Fatal error: Call to undefined function curl_init()
解决：在php.ini 文件中 将 extension=php_curl.dll 前的分号去掉
错误：Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_curl.dll
因为刚才php.ini文件引入的 php_curl.dll 文件系统默认在 ‘C:/php/ext/’下去找
两种解决方式，把该文件拷贝过去，或者php.ini中配置查找路径：
; extension_dir = "./"
; On windows:
extension_dir = "ext" #将此行前面分号去掉
