Extend library with own class

[eluser]imn.codeartist[/eluser]
There are two ways you can create custom library class

1) create a class and place at system\libraries

if you are placing your class here then make sure your Class has prefix of CI_

for example:

Code:

class CI_Payment
{

}

2) create a class and place at system\application\libraries

if you are placing your class here then make sure your filename name has following prefix MY_

for example:

MY_library.php

Code:

class AnyClassName
{

}

now you can use your custom library and extend them
