Windows Process Description:

The module that compiles MySQL clients is known as the libmysql.dll library. The MySQL software technology from MySQL AB provides developers with a fast, multi-threaded, multi-user and robust SQL (Structured Query Language) database server. The MySQL Server was specifically designed for mission-critical, heavy-load production systems and even for embedding into mass-deployed software.

As many MySQL client programs can be written in many languages, the DLL libmysql.dll implements the client library written in C. The functions in this DLL can be used for clients written in C or C++, or for any language that provides C bindings. MySQL Server allows client connection using several protocols, such as TCP/IP sockets, on any platform.

When compiling MySQL clients on Windows, the libmysql.lib library should be linked with the my_global.h code on the libmysql.dll file. The libmysql.lib library is actually just a wrapper to load in the DLL libmysql.dll on demand. Another way is to link the code with the static mysqlclient.lib library. Because MySQL client libraries are compiled as threaded libraries, the code to be used should also be compiled as multi-threaded.

While MySQL supports all PHP (Hypertext Preprocessor) versions, changes in PHP 5 had been incorporated such that the client library is no longer bundled. One reason given by MySQL developers is that most systems popularly used today already have installed client libraries. Not bundling the client library with PHP avoids the mess of having multiple versions in the system. There are assurances that this modification will not actually affect many users.

For example, Unix users usually tend to build PHP against their system's libmysql.dll by simple adding the code -with-mysql=/usr option when building PHP. It is always good to check if the libmysql.dll is available to systems PATH. The libmysql.dll file as well as other PHP related files exists in the PHP folder. Hence, the user should add the PHP folder to the systems PATH to get the client library going.
