php - Split text on some, but not all spaces


I am working on a php project for cooking recipes and am stuck a bit of finding a decent way to split every ingredient from a text area box using PHP.

Here is an example of ingredient lines:

100 grams almonds (preferrably raw) or 1 egg

The text above should be split as follows:

almonds (preferrably raw) && 1,

Bear in mind, that some lines have just two words (spaces) but some would have more. I tried to split the words before the space into an array, however on lines with two words I am getting an error: Undefined offset...




Match words starting composed of[A-Za-z0-9_], then optionally continue matching for your specified occurrences. If you come to realise there are more trailing substrings to cover, just add to the non-capturing group. Demo

$string = '100 grams almonds (preferrably raw) && 1 egg';

        '/\w+(?: && \d+| \([^)]+\))*/',
    ? $m[0]
    : []


array (
  0 => '100',
  1 => 'grams',
  2 => 'almonds (preferrably raw) && 1',
  3 => 'egg',
