PHP regex - removing chars after

I have PHP strings like 

$str1 = "hello ... this is the rest of the line"

or

$str1 = "ASDFDF ... this is also the rest of the line";

I am trying to right a regex statement that will extract the text after "..." appears in the string. I am not able to do this reliably..

so in the above cases, i want to...

 $extract = "this is the rest of the line";

... you get the point.

Why use regex? Just explode the string and pick up the second element in the result:

$str = "hello ... this is the rest of the line";
list(, $rest) = explode(" ... ", $str, 2) + array(, '');

It's basically the same thing, and the regex for this is no faster.

There are multiple ways to do it.

Using strpos and substr:

function rest_of_line($line){
  $loc = strpos($line, '...');
  if($loc !== FALSE){
      return substr($line, $loc+3);
  }
  return $line;
}

$str1 = "hello ... this is the rest of the line";
$str2 = "ASDFDF ... this is also the rest of the line";
echo rest_of_line($str1);
echo rest_of_line($str2);

Or using explode:

$rest = explode('...', $str1, 2); // the 2 ensures that only the first occurrence of ... actually matters.
echo $rest[1]; // you should probably check whether there actually was a match or not
