wampserver安装多php 版本切换出错
一个就行了安装那么多干嘛 肯定要端口冲突的，全部卸载重新安装一个就成。
几种centos下php安装报错原因分析与解决
解决方案
[root@rh-linux software]# rpm -qa |grep libxml2
libxml2-2.6.26-2.1.12
libxml2-python-2.6.26-2.1.12
重新安装libxml2和libxml2-devel包, yum安装的时候发现新版本会提示更新，需要更新的可以更新，不要跳过就行了。
# yum install libxml2
# yum install libxml2-devel -y
安装完之后查找xml2-config文件是否存在
# find / -name "xml2-config"
/usr/bin/xml2-config
