I've been using a script to check submissions for proper email formatting. It looks like this:

 

eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)

 

Note, that I didn't write this script, it was provided by someone else.

 

It's worked fine for years, but now I'm getting an error message saying the function has been deprecated. I think my host must have installed a new version of PHP, 5.3.2.

 

That's cool, I just need to figure out what to replace this code with. I've done a little research and it seems there are several ways to approach this, including:

 

1. just replace "eregi" with "preg_match."

2. use "filter_var" and "FILTER_VALIDATE_EMAIL" instead.

 

Any advice as to what would be the best way to update this script would be greatly appreciated.

 

Thanks!

Thanks, Larry. I'm going to give that a try. Out of curiosity, do you know exactly what the filter "filters?" I looked around on the web and couldn't find any specific information about this. I found that as long as I entered anything with an @ in it it worked. I thought it would also require some sort of .com/.net, etc. at the end, but it doesn't seem to. For example:

 

swilkison (this triggers an error)

swilkison@comcast (this works fine, even though there is no .net at the end)
