pasrsing text for email and http links

[dominant]

I have the following code

function format_links($chk_str){

$final_arrays  = array();

$large_array = explode("<br>", $chk_str);

foreach($large_array as $line){

$final_arrays[] = explode(" ", $line);
}



for($i=0; $i<count($final_arrays); $i++){

  $b =  preg_replace("#([url]http://[/url]([^\s]+))|(www\.[^\s]+)#i", "<a href=\"http://$2$3\">$2$3</a>", $final_arrays[$i]);


$pos = strpos($final_arrays[$i], "@");
if($pos === false){
$email = false;
} else {
print "@ Yeas";
    $email = true;
	}

if($email){
	$final_arrays[$i] = "<a href='mailto:$final_arrays[$i]'>$final_arrays[$i]</a>";
		}
	}



	foreach($final_arrays as $inner_array){
$inner_strings[] = join(" ", $inner_array);
  }

$new_large_string = join("<br>", $inner_strings);

//		$chk_str = implode(" ", $a);
	$chk_str=preg_replace("#([url]http://[/url]([^\s]+))|(www\.[^\s]+)#i", "<a href=\"http://$2$3\" target=_blank>$2$3</a>",	$new_large_string);

	return $chk_str;
}

The problem is that i can see now email link eventhough i have many within my text

Your preg_replace() function's are a bit of a mess and are certainly the problem ... let us know what replacement you want to make so it's easier to see what's wrong.

I fixed them all. I treat every word as an element of an array

It works perfect

function format_links($chk_str){

 $counter=0;

$final_arrays  = array();

$large_array = explode("<br>", $chk_str);

foreach($large_array as $line){

$final_arrays[] = explode(" ", $line);
$counter++;
}

$j=0;	

	for($i=0; $i<$counter; $i++){

		foreach($final_arrays[$i] as $word)


		   {
 // $b =  preg_replace("#([url]http://[/url]([^\s]+))|(www\.[^\s]+)#i", "<a href=\"http://$2$3\">$2$3</a>", $final_arrays[$i]);

  $allthestring[$i][$j]=preg_replace("#([url]http://[/url]([^\s]+))|(www\.[^\s]+)#i", "<a href=\"http://$2$3\" target=_blank>$2$3</a>",	$word);



	if($allthestring[$i][$j]==$word) {
	$pos1 = strpos($word, "@");
	$pos2 = strrpos($word, ".");

//			if($pos1&&($pos2<=(strlen($word)-3))){
    			if(($pos1&&$pos2)&&$pos2<=(strlen($word)-3)){
        $email = true;
			} else {

    $email = false;
		}

		if($email){

			  $allthestring[$i][$j] = "<a href='mailto:$word'>$word</a>";
		}

}
$j++;


}
$j=0;	
}	


	foreach($allthestring as $inner_array){
$inner_strings[] = join(" ", $inner_array);
  }

$new_large_string = join("<br>", $inner_strings);

//		$chk_str = implode(" ", $a);
//	$chk_str=preg_replace("#([url]http://[/url]([^\s]+))|(www\.[^\s]+)#i", "<a href=\"http://$2$3\" target=_blank>$2$3</a>",	$new_large_string);

return $new_large_string;
	//return $chk_str;
}
