# ./configure --with-php-config=/usr/local/php5/bin/php-config --with-mysql=/usr/local/mysql
 (/usr/local/mysql For the installation directory of mysql)

make && make install

5. After compilation, mysql.so is automatically placed in the default php extension directory (phpinfo can be viewed, here is /usr/local/php5/lib/php/extensions/no-debug-zts-20090626), then modify php.ini and remove the semicolon in front of;extension=php_mysql.so. Note: The name of the generated module is mysql.so, which is inconsistent with the name of php_mysql.so in php.ini. Mysql.so must be renamed to php_mysql.so. Remember~! 6. Restart apache:

# service httpd restart

Note: If step 3 passes but an error is reported in step 4, it may be a problem with the source code. You can download a new file from php.net and recompile it.
