类型分为:AAAAA     AAAA     AAA     AABBCC     AABB     AAABBB     AABBB     AAABB     ABABAB     ABAB     AAAAB     升序ABCD     降序DCBA

我通过文本(手机号一个一行)将一组手机号导入到数据库里,需写一个算法,可以得到手机号的类型如手机号(15836998812)这样的为AABB(因为有9988是AABB型的,只要是两个相同的连在一起就可以如1133也是AABB的),15836888812,这样的就是AAAA型的,一共分为
AAAAA型的(如:15836999992,判断依据:99999)
AAAA型的(如:158365111152,判断依据:1111)
AAA型的(如:15836222712,判断依据:222)
AABBCC型的(如:15877889912,判断依据:778899)
AABB型的(如:15866779912,判断依据:6677)
AAABBB型的(如:15811122212,判断依据:111222)
AABBB型的(如:15855666212,判断依据:55666)
AAABB型的(如:15811122712,判断依据:11122)
ABABAB型的(如:15823232312,判断依据:22323)
ABAB型的(如:15836368963,判断依据:3636)
AAAAB(如:15811112569,判断依据:11112)
升序ABCD(如:158123478963,判断依据:1234)
降序DCBA(如:15843215698,判断依据:4321)

递归算看看

请说下详细的算法啊

那请问能否提供下升降序的思路也可以的

'AAAAA' => '(\d)\\1{4}' 这段正则是什么意思呢

'AAAAA' => '(\d)\\1{4}' 这段正则是什么意思呢
(\d) 表示匹配到一个数字
\\1{4} 表示前面匹配到的数字要重复4次

于是他可以匹配
11111、22222、33333、44444、55555、66666、77777、88888、99999、00000

升降序不能用正则表示出来,需要另行判断

$ar = array('15811112569','158123478963','15843215698',);foreach($ar as $tel) {  $u = 0;  $d = 0;  $t = str_split($tel);  for($i=1; $i<count($t); $i++) {    $u = $t[$i] == $t[$i-1]+1 ? $u+1 : 0;    $d = $t[$i] == $t[$i-1]-1 ? $d+1 : 0;    if($u >= 3) {      echo "升序 $tel\n";      break;    }    if($d >= 3) {      echo "降序 $tel\n";      break;    }  }}

此算法有点问题啊  如果是一个  15877998917这样的 应该也是AABB型的 但是他并不能分析出来哎

7楼不错,学习啦
