detect email address in string

ThE_WiZ

Hello, Until recently I was an ASP programmer and I'm now starting with PHP. I want to write a function that takes a string, finds an email address by searching for the @, and then add the HTML tags for making an email link. I've written a function, but when I use it on a string from my MySQL DB, the result is: 0. I'm a real Newbie, can anyone help? Thanks!:

function huntemail_string ($string) {
for ($tel1 = 1; $tel1 <= strlen($string); $tel1++) {
if (substr($string,$tel1,1)=="@") {
for ($tel2 = $tel1; $tel2 <= 1; $tel1--) {
if (substr($string,$tel2,1)==" ") {
$final=subst($string,1,$tel1);
$final=$final&"<a href=\"mailto:";
$startmail=$tel1;
break;
}
}
for ($tel3 = $tel1; $tel3 <= strlen($string); $tel3++) {

			if (substr($string,$tel3,1)==" ") {
				$final=$final&substr($string,$startmail,$tel3-$startmail-1);
				$endmail=$tel3;
				$final=$final & "\">";
				$final=$final & substr($string,$startmail,$endmail-$startmail);
				$final=$final & "</a>";
				break;
			}
		}
		break;
	}
}
$final=$final & substr($string,$endmail,strlen($string)-$endmail);
return ($final);

}

ow, I forgot, a string that is injected in this function is for example:

For more support mail me mailadres@domain.com with support in the subject line.

Hmm, in my previous post, the email address is transformed to incliude the email link. Anyone got the code? 🙂

Welcome to the forums here.

I think you need to take a look at PHP's support for regular expressions: http://www.php.net/preg_match

And be sure to read the comments at the bottom of the page...

( i would give you more advice, but I am just learning regular expressions myself...)

I use the following when checking emails with regular expressions. It takes a while to figure out regular expressions - it is almost it's own language.

eregi('^{[a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9]+(.[a-z0-9-]+)$',$email);}

Sorry guys, I'm not looking for validating an emailadres, I just want to make it clickable (mail link). So, if there's an email address anywhere in the text, I want the function to add the html, so visitors on my site can click on the emailaddres...

You can find an email adress by validating and using a if else statement to make sure he does something with the email adres.

Start bij checking a text on the @/. and for/middle/back text, to find the email adresses. Create an array to make sure u get them al.

Make one basic link for click on and use the array between { } and make sure you repeat it untill u had 'm all..

Don;t know if this is what u mean..and im a newb to..
