Question

I am recieving the error:

Deprecated: Function eregi() is deprecated in C:\wamp\www\registration\class.register.php on line 75

with my code::

if(empty($this->email) || !eregi('^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]{2,4}$',$this->email))

What alternative should I use and how can I implement it????

Answer 1

Yes ereg family functions have been deprecated, you need to use preg family functions instead. In your case, you should use preg_match instead.

That piece of code is equivalent to:

if(empty($this->email) || 
    !preg_match('~^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]{2,4}$~i',
    $this->email))

It can also be compacted to:

if(empty($this->email) || !preg_match('~^[\w.-]+@[\w.-]+\.[a-zA-Z]{2,4}$~i',
    $this->email))
