php - preg_match_all使用

我有一个始终遵循以下格式的字符串:

This Fee Name :  *  Fee Id  * Fee Amount  $* is required for this activity

例:

This Fee Name :  STATE TITLE FEE  Fee Id  2 Fee Amount  $5.50 is required for this activity

我想使用PHP进行的操作是传递字符串并获取结果

STATE TITLE FEE

2

5.50

我很确定preg_match_all是我想要的，但是无法弄清楚如何正确使用正则表达式。

最佳答案

请尝试以下操作:

$a = 'This Fee Name :  STATE TITLE FEE  Fee Id  2 Fee Amount  $5.50 is required for this activity';
$regex = '/This Fee Name :  (.+)  Fee Id  (.+) Fee Amount  \$(.+) is required for this activity/';
$matches = array();
preg_match($regex, $a, $matches);
var_dump($matches);

输出:

array(4) {
  [0]=>
  string(91) "This Fee Name :  STATE TITLE FEE  Fee Id  2 Fee Amount  $5.50 is required for this activity"
  [1]=>
  string(15) "STATE TITLE FEE"
  [2]=>
  string(1) "2"
  [3]=>
  string(4) "5.50"
}
