This is a function that you can embed in your PHP applications that will help you extract email addresses from a given piece of text.
Tested on a string of (actually 4 - 5 paragraphs) text and this has performed very well.
Please feel free to use this code in your applications and let me know if you face any issues (http://www.navioo.com)
<?
$text = ' Montreal based PR firm seeking staff to work events, promotions and marketing campaigns. All candidates must be bilingual, work well with others, outgoing, charismatic, and energetic.(Experience is an asset).
<br><br>
For consideration kindly forward a copy of your CV and a recent photo of yourself to mybest@bizcaf.com ';
function parseTextForEmail($text) {
$email = array();
$invalid_email = array();
$text = ereg_replace("[^A-Za-z._0-9@ ]"," ",$text);
$token = trim(strtok($text, " "));
while($token !== "") {
if(strpos($token, "@") !== false) {
$token = ereg_replace("[^A-Za-z._0-9@]","", $token);
//checking to see if this is a valid email address
