Fatal error: Call to undefined function mssql_connect() 这种提示是证明php与mssql数据库连接不成功,并且mssql_connect()这个函数不能使用
现在我们来看看解决方法:
第一步:查看你c:\php\目录下有ntwdblib.DLL这个文件吗?如果有再看查看你c:\windows\system32\目录下有没有这个文件ntwdblib.DLL如果还是有,但还是同样的提示错误就再看看c:\windows\system32\目录下有没有php_mssql.dll这个文件,如果没有就在你的php目录下C:\php\ext\找到php_mssqll.dll文件,如果有就找其它原因,看看你的php.ini里的;extension=php_ming.dll
;extension=php_mssql.dll
前面的;去了没,如果没有去了,重起apahce 试试看,大多数据这个时间会成功了,如果还是不行,就看看你php目录下的ntwdblib.dll版权是不是和你mssql server的版本相同,如果不同就把mssql目录下的拷贝到上面那几个寺主就行了.
这些方法都是我在实际中得来了,请各位转载注明来自:www.111cn.net
