php - 正则表达式获取双花括号内的值 "{{ }}"

Question

PHP 中的正则表达式，用于在数组中获取用“{{ }}”引用的文本。

例如:

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

需要输出如下数组，

array(value1,value2,value3);

Answer 1

这将起作用:

$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]);

输出:

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