In PHP I’m getting the following warning whenever I try to connect to a database (via mysql_connect)
Warning: mysql_connect(): Headers and client library minor version mismatch. Headers:50162 Library:50524
In my php -i output I have the following values listed under mysqli
Client API library version => 5.5.24
Client API header version => 5.1.62
I’ve tried updating php5-mysql and php but I’m already at the latest version of both of them. How do I go about updating the header version so I stop seeing this warning?
EDIT
My MySQL files should all be updated to be the latest version:
$ apt-get install mysql.*5.5 . . . mysql-client-5.5 is already the newest version. mysql-server-core-5.5 is already the newest version. mysql-server-5.5 is already the newest version. mysql-testsuite-5.5 is already the newest version. mysql-source-5.5 is already the newest version.
Removing old versions
$ apt-get remove mysql.*5.1 . . . Package handlersocket-mysql-5.1 is not installed, so not removed Package mysql-cluster-client-5.1 is not installed, so not removed Package mysql-cluster-server-5.1 is not installed, so not removed Package mysql-client-5.1 is not installed, so not removed Package mysql-client-core-5.1 is not installed, so not removed Package mysql-server-5.1 is not installed, so not removed Package mysql-server-core-5.1 is not installed, so not removed Package mysql-source-5.1 is not installed, so not removed

Answer
Your PHP was compiled with MySQL 5.1 but now it is linking a mysql library of 5.5.X family. You have to upgrade PHP to a version compiled with MySQL 5.5 or revert back mysql client libraries to 5.1.x.
