[SOLVED] PHP fatal error 'Undefined class constant MYSQL_ATTR_USE_BUFFERED_QUERY'?

Sarika.k | | 1 min read

While settings up local installation in my system I came across this error (PHP fatal error 'Undefined class constant MYSQL_ATTR_USE_BUFFERED_ QUERY'). I tried a lot to fix it. Finally got the solution as follows. The reason for this error is missing pdo_mysql extension in my PHP installation.

Install the php5-mysql on Ubuntu using the following command:

sudo apt-get install php5-mysql

Restart apache using the command:

 sudo service apache2 restart

Notes:

'MYSQL_ATTR_USE_BUFFERED_QUERY' is to store the whole recordset in memory. If this is set to TRUE then the MySQL driver will use the buffered versions of the MySQL API.
