This library provides functions to emulate the infamous and deprecated mysql extension,
using the modern mysqli extension behind the scenes.
The purpose is to allow legacy applications using the mysql extension
to function adequately in PHP 7.0 and beyond,
where the mysql extension will not be available.
All functions are designed to behave as similarly as possible
to the way the original mysql extension does.
There may be minor differences, however, in unusual cases.
Please report any discrepancy that you find.
The only difference that cannot be fixed is that
the mysqli connection is an object, not a resource.
So if you use is_resource($var) to test whether a connection is active,
you should change it to is_object($var) or $var instanceof mysqli.
Access all advanced mysqli features,
such as transactions and prepared statements, can be accessed
by calling the corresponding methods directly on the connection object.
This library should not be taken as a justification
for writing new applications using the mysql extension.
Legacy applications using the mysql extension
should be ported to mysqli or PDO as soon as possible.
Please feel free to consult the inner workings of this library
to learn how to port mysql code to mysqli code that behaves in the same way.
