我正在使用下面的正则表达式来验证电话号码。但是下面列出的某些格式应该无效。
+ 5-555-555-5555，+ 5.555.555.5555，+ 5 555 555 5555，+ 5（555）555 5555，+ 55555555555，
PHP代码：
$phone_numbers = array(
'555-555-5555',
'5555425555',
'555 555 5555',
'1(519) 555-4444',
'1 (519) 555-4422',
'1-555-555-5555',
'1-(555)-555-25555',
'555 555 5555',
'(555) 555-5555',
'(555)555-5555',
'555-555-5555',
'555.555.5555',
'5555555555',
'5-555-555-5555',
'5.555.555.5555',
'5 555 555 5555',
'55555555555',
'+5-555-555-5555',
'+5.555.555.5555',
'+5 555 555 5555',
'+5 (555) 555 5555',
'+55555555555'
);
$regex = "/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i";
foreach( $phone_numbers as $number ) {
echo $number . ': ' . ( preg_match( $regex, $number ) ? 'valid' : 'invalid' ) . '<br/>';
}
结果 ：
555-555-5555: valid
5555425555: valid
555 555 5555: valid
1(519) 555-4444: valid

1-(555)-555-25555: invalid

(555) 555-5555: valid
(555)555-5555: valid

555.555.5555: invalid

5 555 555 5555: valid

+5-555-555-5555: invalid-------------- Should be true

$regex = "/^\+?(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3}[\s-]?\d{4}$/i";
