| Posted by WebCobra, 02-11-2010, 07:55 PM | | Hi im curious. What is the difference with preg and ereg?
and then i find in the php manual that ereg and eregi are bad. In the future, would ereg won't exist?

Plus its depreciated, so using it would cause your scripts to become broken in the future (just depreciated as of 5.3.0 it looks like, so it will be the the not so distant future that it will no longer work at all).

ereg is the POSIX compliant regex library
The preg functions are often faster and you can do much more complex things with them. So I wouldn't waste your time with ereg at this point since it's deprecated and is being removed from PHP.
