REGEX question.

[solidcodes]

Hi guys

I want to scrape emails addresses in my own website.
http://czone01.com/

using REGEX while i'm formulating my own REGEX.
Please i dont need DOM this time i only need REGEX.

Please assume that these email addresses will change someday.

Thank you in advance,

First of all, pretending that it's for your own site isn't really going to get you anywhere - we all know that scraping is for OTHER sites

Maybe would have persuaded us if there was more than one email address on the entire site...

I assume that you know how to use the preg functions.

If you want a simple email pattern:

$Regex = "/[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}/"; 

Or if you want a better but more complicated pattern:

$Regex = "/a-z0-9!#$%&'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+\/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/";

Capturing email addresses with Regular Expressions

We all know that capturing email addresses with regular expressions can be tricky but I think, in this case at least, the following might be useful. If not, you can at least use it as a building block to tweak and make suitable for your particular needs.

Description
array capture_email( string $sSubject)
Searches sSubject for email addresses present within it.

Function Definition

function capture_email($sSubject)
{
    static $sRegexFu = '
        /
        
        (?# --
          # This pattern captures
          # only real and proper 
          # email address!
          # -- )
        
        
        \b(?:[\!"#\$%\'\(\)\*\+,\-\&
        \:;@                    \?\^
        _`  \{                \|  \}
        \]    \*             \?   \[
        \!      \#         $%     ])
        *\K  (?:  [a-z0-9]+  @[   {}
        &\' *+                 \/ =?
        ^`a-z~-]+(?:\.[a-z0-9]+)?)\b
        
        
        (?# -- End of Email Capture --)
        
        /x';

    // Return the array of emails (which may be empty!)
    if (preg_match_all($sRegexFu, $sSubject, $aEmails) !== FALSE)
        return array_shift($aEmails);
    
    return FALSE;
} 

Returns
An array of email addresses present within the sSubject string (an empty array if none) or FALSE on error.

Example

print_r(
    capture_email('
        Get in touch at email@domain.com 
        but make sure not to be a silly 
        person by spamming nospam@domain.com!
    ')
); 

The above example will output:

Array
(
    [0] => email@domain.com
    [1] => nospam@domain.com
)
