Function emailvalidate

Hi Guys,

I am new in PHP and have an issue with emailvalidate function see my code below. This works for any other email validation but except for .africa domain. if I put for example it get rejected with an alert “emails is invalid” see my reg expression code below and advise
This @"^[-a-zA-Z0-9][-.a-zA-Z0-9]@[-.a-zA-Z0-9]+(.[-.a-zA-Z0-9]+).

Both do not work.
Please assist



The regular expression to validate an email is enormous; I’d recommend you use PHP’s built in functions to do it instead.

filter_var($email, FILTER_VALIDATE_EMAIL);

will return false if $email is not a valid email. Note that this doesn’t check that the email actually exists; the only way to do that is to send a message to the address and ask the recipient to respond.

If you do want to use a regular expression to validate the email, here are the ones used by PHP internally.

Thanks for your quick response skawid,

All I need is just to get the email address to be accepted on the input form am not really worried if the email address exist or not.
I know in C# there is something similar to the below which works but as am new on PHP am not sure what is the equivalent of this in PHP?


If you just need to validate the email, I would use:

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // handle invalid email here

where $email is the email that has been submitted.

As stated, you don’t need the regex, use the function.
