$s = <<< TEXT
在字符串里找这样一个字符串，数字没有规律也没有长度规律
7|23|63|14|51|65……
你不能说清楚一点吗？总是要人猜你的意图，这样不好
TEXT;
preg_match_all('/[\d|]+/', $s, $r);
print_r($r[0]);Array
(
    [0] => 7|23|63|14|51|65
)
上面那些正则都有问题的找出来会变成
Array ( [0] => 1|2|39|40|41|42 [1] => 41| )
这个错了
重写一个$str = <<<STR
就是这样？7|23|63|14|51|65……在字符串里找这样一个字符串，数字没有规律也没有长度规律
STR;
preg_match_all('/(\d+\|?)+/', $str, $matches);
print_r($matches[0]);
/*
Array ( [0] => 7|23|63|14|51|65 )

14楼你写的也是会多找出一个的
Array ( [0] => 1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31|38|39|40|41|42 [1] => 41| )
更正一下，2个以上的匹配会形如下面
Array
(
    [0] => Array
        (
            [0] => 7|23|63|14|51|65
            [1] => 7|23|63|14|51|68
        )    [1] => Array
        (
            [0] => 51|
            [1] => 51|
        ))
