Get strings which are inside double braces

Question

I have a string where some part of the string is inside braces, and I would like to get them in an array.

The string is for example: Lorem {{ipsum}} dolor sit amet, {{consectetur}} adipiscing elit.

And I would like to get: array("ipsum", "consectetur")

I tried this:

$regExp = "/\{\{([^)]+)\}\}/";
$result = preg_grep($regExp, array("Lorem {{ipsum}} dolor sit amet, {{consectetur}} adipiscing elit."));

but I get back the given string as result

Answer 1

You are using the wrong function, you should use preg_match_all().

You should also use lazy instead of greedy matching to avoid the result being ipsum}} dolor sit amet, {{consectetur. You can do that by adding a ? after your quantifier:

$regExp = "/\{\{([^)]+?)\}\}/";
                      ^ here
preg_match_all($regExp, "Lorem {{ipsum}} dolor sit amet, {{consectetur}} adipiscing elit.",
               $result);

var_dump($result);

A working example.
