Help with deprecated eregi

[9999]

Could someone help me with these 2 lines.  Many thanks in advance!

 

 

 

        if(!eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $_POST['email'])) { 


          if(!eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $value)) {

A quick search for "differences between eregi and preg php" yielded, amongst lots other, these two results:

Just use preg_match instead, and be aware that eregi was case insensitive, while preg_match is case sensitive.

It just means you need to add A-Z next to every time you use a-z, that is if you want to allow A-Z, but I suppose you do, because you were allowing that before.

 

"^[a-zA-Z0-9\._-]+@+[a-zA-Z0-9\._-]+\.+[a-zA-Z]{2,3}$"

 

Like that.

 

I don't think it's a safe code to validate input, because $ only match end of line, not end of string. \Z I think is end of string, and you should also use \A at the beginning instead of ^.

 

 

I also think there exists a function to validate emails without needing to use regex for it:

Thanks.  I got this from some old free script.
