/eat (apple|pear)/
/I like/

and text

\"I like to eat apples on a rainy day, but on sunny

Please keep in mind that if you use preg_match, and a group isn't matched then not an array will be returned, but an empty string. You can use T-Regx and use cleaner API:

$o = pattern('eat (apple|pear)')->match($text)->offsets()->all();
$o // [10, 14]

Or if you want some more advanced matches

pattern('eat (apple|pear)')
  ->match($text)
  ->iterate(function (Match $m) {
      $m->text();   // your fruit here
      $m->offset(); // your offset here
  });
