[RESOLVED] Function for RGB2Hex/Hex2RGB

Hi,
Where i can find function for RGB2Hex/Hex2RGB(Complete)?
Also what is difference between @fsockopen V.S. fsockopen?
Thanks for help ;).

1. A search engine.

2. The '@' symbol is the error-suppression operator. It allows you to execute a statement or expression and disregard any errors that occur. It is not generally good practice except for dealing with functions which throw warnings instead of returning status codes.

Thanks Penagate.
Resolved! ;)
