There is such a sentence in the log

PHP Startup: Unable to load dynamic library 'd: \ myserver \ php \ ext \ php_mysql.dll'

PHP Fatal error: Call to undefined function is prompted when the php_mysql file is not loaded successfully.

Mysql_connect (), which means that mysql is not connected successfully, that is, loading mysql database fails. according to the analysis, there are two possible causes:

Yes, this problem does not exist because I used to decompress this php package. 2 is a server environment variable problem. if it is an environment variable, there are two solutions.

Solution

1. add environment variables directly in windows.

2. find php5ts. dll in d: PHP and copy libmysql. dll to c:/winnt/system32 (winNT/2000 ),

WinXP/2003 is copied to c:/windows/system32.

Remember to record the apache environment after copying the file to the system directory. for example, you can test http: // localhost/a. php again.

The output is related to phpinfo. the Source www. bKjia. c0m is reprinted in the original article on this site.
