PHP Question

Headers and client library minor version mismatch

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.
