字符串:
TKPC10090987TKPC10098M9YTKMR120990U9TKMR10059E56

要求:
1、截取每一个TKPC和TKMR后的连续5位数。(例中的截取出来就应该是TKPC有11090,12098,TKMR有12099,11059)
2、将截取后的数字按照如下条件对比,为真的echo yes。
      2.1   TKPC的两组数字,如果有小于等于11069的话, ECHO满足条件的每组TKPC+后8位。
      2.1   TKMR的两组数字,如果有小于等于10999的话, ECHO满足条件的每组TKMR+后8位。

$str = "TKPC10090987TKPC10098M9YTKMR120990U9TKMR10059E56";for ($i = 0, $len = strlen($str); $i < $len; $i++){    if (substr($str, $i, 4) == 'TKPC'){        if (substr($str, $i+4, 5) <= 11069){            echo 'TKPC' . substr($str, $i+4, 8) . "\n";        }    }    if (substr($str, $i, 4) == 'TKMR'){        if (substr($str, $i+4, 5) <= 10999){            echo 'TKMR' . substr($str, $i+4, 8) . "\n";        }    }}
