You may use

preg_replace('~\[\[((?:(?!\[\[).)*?)\|(.*?)]]~s', '<a href="$1">$2</a>', $string)

See the regex demo

Details

  • \[\[ - a [[ substring
  • ((?:(?!\[\[).)*?) - Group 1 ($1 in the replacement pattern refers to the value inside this group): any char (.), 0 or more occurrences but as few as possible (*?), that does not start a [[ char sequence ((?!\[\[))
  • \| - a | char
  • (.*?) - Group 2 ($2):
  • ]] - a ]] substring.

See the PHP demo:

$string = "[[some_non-matching_text]] [[https://example.com|link]] [[this is not matching either]] [[http://example2.com|link2]]";
echo preg_replace('~\[\[((?:(?!\[\[).)*?)\|(.*?)]]~s', '<a href="$1">$2</a>', $string);
// => [[some_non-matching_text]] <a href="https://example.com">link</a> [[this is not matching either]] <a href="http://example2.com">link2</a>
