我已经有一个小功能，但无法正常工作。:-)

     function getInbetweenStrings($start, $end, $str){
       $matches = array();
       $regex = "/$start([a-zA-Z0-9_]*)$end/";
       preg_match_all($regex, $str, $matches);
       return $matches[1];
    }

调用方法为

        $start = "Consolation Prize- Rs. 8,000\/-";
        $end = "2nd Prize- Rs :500,000\/-";
        $consold = $this->getInbetweenStrings($start, $end, $content1);
        print_r($consold);

您刚刚错过了角色类中的空间。

$regex = "/$start([a-zA-Z0-9_ ]*)$end/";
#                    here ___^

$explode2 = explode($end_pahrase, $explode1_data);

echo $result = $explode2[0];

上面的代码经过测试和工作。

它会导致你

NN 189822 NO 189822 NP 189822 NR 189822 NS 189822 NU 189822 NV 189822 NW 189822 NX 189822 NY 189822 NZ 189822

我希望这能帮到您。

谢谢
