PHP REGEX：PREG_SPLIT（）需要帮助以获取邮政编码

Question

I have content like

San Clemente, CA 92673

or

Arlington, TX 76012-3693

And I need to split it into CityAndState and Zip.
Some

I'm trying:

$moreAddressInfo = preg_split('^[0-9.]{5,}^', $row2['cityAndZip'],null,PREG_SPLIT_DELIM_CAPTURE);

(also tried without the flag)
... the CityState portion is getting returned just fine, but the main Zip info is missing
(for the above two examples, $moreAddressInfo[1] would equal '' and '-3693', respectively).

Any pointers ?

Answer 1

Try this:

$moreAddressInfo = preg_split('~\s+(?=[0-9]{5})~', $row2['cityAndZip']);

• \s+ matches one or more whitespace characters.

• (?=[0-9]{5}) is a positive lookahead; it asserts that the next part of the string is five digits, but doesn't consume them.

So your delimiter is some whitespace that's followed by five digits.
