 if(!function_exists('your_function_name')) {     function your_function_name() {         //....�p�G�] �I function_exists �] ' your_function_name ' �^ �^ �]�\��your_function_name �] �^ �] //.... Function code     } }�\��N�X�^ �^ 

It is a good idea to always define and consistently use a namespace.�o�O�@�Ӧn�D�N�A�n�l�ש�T�M�@�e�ϥΪ��W�r�Ŷ��C For example we name all our plugin functions prefixed with tg, to identify our company.�Ҧp�ڭ̪��W�r�ڭ̩Ҧ�������\��A�e��PTG �A�H�T�w�ڭ̪����q�C
