I have blocks of free text that contain phone numbers and multiple 6 digit numbers that I need to capture. The 6 digit number has an optional ','.
我有*文本块,包含我需要捕获的电话号码和多个6位数字。 6位数字有一个可选的','。
examples of the 6 digit numbers could be 123456, or 123,456, but I need to differentiate from a phone number like 1 234 456 8901
6位数字的例子可能是123456,或123,456,但我需要区分电话号码,例如1 234 456 8901
I have :
我有 :
preg_match_all(",\[\W_][0-9]{3}(?:,)[0-9]{3}[\W_][\D]\d",$html, $value);
Is there a better way to do this?
有一个更好的方法吗?

It's a bit difficult to review the regex without the sample input but couple of observations:
在没有样本输入的情况下查看正则表达式有点困难,但有几点观察:
-
[0-9]can be replaced with\d(since, you're already using it at the end)[0-9]可以替换为\ d(因为,你最后已经在使用它了)
-
[\D]is exactly the same as\D. It's a character class itself and unless you have some more characters to include it'ss fine without being enclosed in[].[\ D]与\ D完全相同。它本身就是一个角色类,除非你有更多的角色要包含它,否则不会被包含在[]中。
-
(?:,)should simply be,because you neither want to capture it nor it has any quantifiers.(?:,)应该只是,因为你既不想捕获它也不想有任何量词。
-
,\[\W_]Here it seems you want to use the character class but the\would escape the first[. If you actually need a literal\there; you need to escape it as\\since it's a special character.,\ [\ W_]这里似乎你想要使用字符类但是\会逃脱第一个[。如果你真的需要文字\那里;你需要把它作为\\来逃避它,因为它是一个特殊的角色。
