what's the diff b't @include_once and include_once?

[vidago]

As per subject, what is the diff b't them? and what's the usage of the '@' added when include or require a file?

Thanks
Louis

The "@" character silences all warning/error output from the function.

e.g. if the file you are intending to include is missing, you'll generally get an error message.

If you add the "@" character, nothing will be printed to the browser. This works for other functions as well.

e.g. @opendir("some secret folder");

A little word of advice: handle errors, don't hide them.
