EmailDetect Library - A simple solution to detect emails into strings.

Hi CI Masters!
I'm here to share a library that i write to find valid emails into string datas. It's a simple (really simple!) library, that you can use to work with various emails at the same time.

So... Let's to the code.

Code:

<?php

/**
* EmailDetect
*
* Provide methods to crawling some string and find valid emails.
*
* @author    Joel Wallis <[email protected]>
* @version    1.0
*
* @access    public
* @param    string    $str    The string that contain or not valid emails.
* @return    void
*/

class EmailDetect {
    
    private        $ci;
    public        $input;
    public        $list = array();
    public        $qtd;
    private        $regex = '/[^\da-zA-Z@\.-]/mi';
    
    
    public function __construct($str = null)
    {
        $this->ci =& get_instance();
        $this->ci->load->helper('email');
        
        if($str)
        {
            $this->input = $str;
            $this->run();
        }
    }
    
    
    /**
     * run
     * void run() - Run the crawling.
     *
     * @access    private
     * @return    void
     */
    
    public function run($str = null)
    {
        $this->input .= $str;
        $this->split();
    }
    
    
    /**
     * split
     * void split() - Split the string with any that isn't a letter, a number or the '@', '_' and '.' chars.
     *
     * @access    private
     * @return    void
     */
    
    private function split()
    {
        $this->input    = strtolower($this->input);
        $input_list        = preg_split($this->regex, $this->input);
        
        foreach($input_list as $item)
        {
            if(valid_email($item) && count(array_keys($this->list, $item)) == 0)
            {
                $this->list[] = $item;
            }
        }
        
        $this->qtd = count($this->list);
        $this->input = "";
    }
}

?&gt;

To use it, is very simple...

Code:

<?php
class MyController extends Controller
{
    function index()
    {
        $this->load->library('emaildetect');
        $this->emaildetect->run($this->input->post('textarea_emails'));
        
        /*
            You can take your emails into the list array property ($this->emaildetect->list).
            You can load the library and inserting data to the crawling at same time.
        */
        
        $this->load->library('emaildetect', $this->input->post('textarea_emails'));
        
        /*
            For example, you can print the emails...
        */
        
        print "<h2> Printting the emails ! </h2>";
        
        foreach($this->emaildetect->list as $id => $email)
        {
            print "<p> list[$id] : $email </p>";
        }
    }
}
?&gt;

Sorry for the weak english, i'm trying my best! uhauhauhuhaa
