php – Tweak在电话号码上使用Preg_Match()

问题：我的模式很接近,但我需要一些帮助来摆脱电话号码之前的任何文字.如何摆脱前面的字符串“嘿我的手机是”？

PHP代码

$pattern = '/.*?(?:1(?:[. -])?)?(?:((?=d{3})))?([2-9]d{2})'
    .'(?:(?<=(d{3})))? ?(?:(?<=d{3})[.-])?([2-9]d{2})'
    .'[. -]?(d{4})(?: (?i:ext).? ?(d{1,5}))?.*?/';;

$subject = 'Hey my phone is 911-628-4539,call me tonight at 9:16:00pm,my room is 122-1001';

preg_match($pattern,$subject,$match);

print_r($match);

产量

Array ( [0] => Hey my phone is 911-628-4539 [1] => 911 [2] => 628 [3] => 4539 )
