根据生成正则表达式以匹配任意数值范围,并在Regex_For_Range为您的示例生成此类正则表达式之后:
\b0*(1[1-9][0-9]|[2-9][0-9]{2}|1[0-9]{3}|2[01][0-9]{2}|22[0-2][0-9]|223[0-4])\b
会做的伎俩.
该过程将(仍然遵循该Regex生成器):
首先,分成相等的长度范围:
110 - 999
1000 - 2234
其次,闯入产生简单正则表达式的范围:
110 - 199
200 - 999
1000 - 1999
2000 - 2199
2200 - 2229
2230 - 2234
将每个范围转换为正则表达式:
1[1-9][0-9]
[2-9][0-9]{2}
1[0-9]{3}
2[01][0-9]{2}
22[0-2][0-9]
223[0-4]
折叠相邻的10:1 [1-9] [0-9] [2-9] [0-9] {2} 1 [0-9] {3} 2 [01] [0-9] {2 22 [0-2] [0-9] 223 [0-4]
结合上面的正则表达式产生:
0*(1[1-9][0-9]|[2-9][0-9]{2}|1[0-9]{3}|2[01][0-9]{2}|22[0-2][0-9]|223[0-4])
接下来我们将尝试使用树来分解公共前缀:
根据正则表达式前缀解析为树:
. 1 [1-9] [0-9]
+ [0-9]{3}
+ [2-9] [0-9]{2}
+ 2 [01] [0-9]{2}
+ 2 [0-2] [0-9]
+ 3 [0-4]
将解析树转换为正则表达式产生:
0*(1([1-9][0-9]|[0-9]{3})|[2-9][0-9]{2}|2([01][0-9]{2}|2([0-2][0-9]|3[0-4])))
我们选择较短的一个作为结果.
\b0*(1[1-9][0-9]|[2-9][0-9]{2}|1[0-9]{3}|2[01][0-9]{2}|22[0-2][0-9]|223[0-4])\b

\n您可以将以下范围的正则表达式放在一起：
1[1-9]\d = 110-199
[2-9]\d\d = 200-999
1\d\d\d = 1000-1999
2[0-1]\d\d= 2000-2199
22[0-2]\d = 2200-2229
223[0-4] = 2230-2234
来形成：
(1[1-9]\d|[2-9]\d\d|1\d\d\d|2[0-1]\d\d|22[0-2]\d|223[0-4])
\d 表示 [0-9]，但少三个字符
虽然你可以用一些看起来很荒谬的正则表达式来做到这一点（正如 VonC 回答的那样），正则表达式真的不应该这样做..为什么不将数字检查推迟到重定向到脚本？
如果号码110-2234转到SCRIPT1，以及1-109转到SCRIPT2，这将是很多简单以指导所有数字router脚本，并将其重定向到正确的位置（通过HTTP重定向）..
在.htaccess：
RewriteRule ^view/([0-9]+)/?$ router.php?page=$1 [L]
..then in router.php，类似于：
<?PHP
if(
int($_GET['page']) > 110 &&
int($_GET['page']) < 2234
){
header("Status: 301 Moved Permanently\nLocation: /script1");
}else{
header("Status: 404 Not Found");
}
?>
