问题描述

PHP中的正则表达式，用于获取数组中用"{{}}"引用的文本.

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

例如:

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

需要像下面的数组一样输出

Need output as like below array,

array(value1,value2,value3);

推荐答案

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"
}
