php - Regular expression to get the value inside double curly braces "{{ }}"

Question

Regular expression in PHP to fetch the text quoted inside with "{{ }}" in an array.

For eg:

$str = "This is sample content with a dynamic value {{value1}} and also have more dynamic values {{value2}}, {{value3}}";

Need output as like below array,

array(value1,value2,value3);

Answer 1

This will work:

$str = "This is sample content with a dynamic value {{value1}} and also have more dynamic values {{value2}}, {{ value3 }}";
if (preg_match_all("~{{s*(.*?)s*}}~", $str, $arr))
   var_dump($arr[1]);

OUTPUT:

array(3) {
  [0]=>
  string(6) "value1"
  [1]=>
  string(6) "value2"
  [2]=>
  string(6) "value3"
}
