Support for PHP extended mysqli in Linux systems

Note: The MYSQLI expansion Library is designed to work in conjunction with MySQL 4.1.3 or later

The first two days a site to transfer over, because there are problems to my database, I did not carefully deal with this site. Today the database is ready, found still not use, reported errors are as follows: Fatal error:class ' mysqli ' not found in. Originally I was compiling PHP before, did not put mysqli support compiled in, the solution to the problem is to recompile

To install the mysqli extension of PHP, add--with-mysqli=mysql_config_path/mysql_config when configured. Where Mysql_config_path represents the path to the Mysql_config program, which is released with MySQL greater than 4.1 version

CD php-5.2.8//There's a mysqli in the Ext folder underneath.
CD Ext/mysqli

Linux will be the source file compiled should have configure it, but here is not, after we have installed PHP, php5 folder in the command directory bin there is a file called phpize, use it can generate configure files, continue to

/usr/local/php5/bin/phpize//Here Enter the run, after the execution of the Configure file,
./configure–prefix=/usr/local/mysqli–with-php-config=/usr/local/php5/bin/php-config–with-mysqli=/usr/local/ Mysql/bin/mysql_config

Direct return, no problem will continue.

Make
Make Test
Make Install//(no error will show installing shared extensions:/usr/local/php5/lib/php/extensions/no-debug-non-zts-20041030/)

Now the mysqli.so file is coming out.

It's OK to load this file directly in the php.ini.

Extension_dir= "/usr/local/php5/ext"
Extension=mysqli.so

Find the first line above to change to this, and then add the second line. Wq Save exit.

mysqli.so this file CP to/usr/local/php5/ext.

Restart Apache.
