PHP Startup: Unable to load dynamic library_PHP教程

Yesterday, I helped a friend configure the server and found that there was a PHP Warning: PHP Startup: Unable to load dynamic library prompt in the apache log. Then when debugging the database connection, I found a Call to undefined function mysql_connect() error, so I thought of it. The problem is that mysql did not load successfully. Let's take a look at the solution to the problem.

Connection code

echo 'a';
$cn = mysql_connect("localhost",'www.bKjia.c0m','your mysql user password') or die(mysql_error()) ;
if( $cn )
{
echo phpinfo();
}
else
{
echo 'mysql connect fail';
}
?>

Because the server uses a secure php.ini and no errors are displayed, Yu Shixiang looked at the errors.log log text in the logs of the apache installation directory

The following error was found

PHP Warning: PHP Startup: Unable to load dynamic library

'D:myserverphpextphp_mysql.dll' - xd5xd2xb2xbbxb5xbdxd6xb8xb6xa8xb5xc4xc4

There is this sentence in the log

PHP Startup: Unable to load dynamic library 'D:myserverphpextphp_mysql.dll' This means

The php_mysql file was not loaded successfully. Another point is the prompt PHP Fatal error: Call to undefined function

mysql_connect(), this means that mysql is not connected successfully, that is, loading the mysql library fails. According to analysis, there are two possibilities: one is that the file is not

Exists, this problem does not exist because I used this php decompression package before, 2 is the problem of server environment variables, if it is environment variables, there are two solutions

Solution

1, add environment variables directly in windows

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

For winXP/2003, just copy it to c:/windows/system32

Remember that after copying to the system directory, you must remember the apache environment. If I test http://localhost/a.php again, you can see
