我需要帮助编写与某些数据中的电话号码匹配的常规表达式。Somin格式如下:
XXX-XXX-XXXX
XXX-XXX-XXXX Ext. XXX
XXX-XXX-XXXX Ext. XXXX
(XXX) XXX-XXXX
XXX-XXX-XXXX (Text)
XXX.XXX.XXXX
还有一个专门针对这一行的正则表达式:
XXX-XXX-XXXX (Text & Special Chars.); XXX-XXX-XXXX (Text)
我已经搜索了几个问题,并尝试了一般的0-9匹配,但到目前为止都无济于事。我最近也尝试过这种方法来获取正常的电话号码:
preg_match_all('/^(('('d{3}') ?)|('d{3}-))?'d{3}-'d{4}$/', $a3, $n);
print_r($n);
有人能给我指正确的路吗?感谢
此模式将与您在任何文本中提供的示例相匹配。
((?:'d{3}[.-]|'('d{3}')'s+)'d{3}[.-]'d{4})(?:'s+Ext'.'s+('d+)|'s+'(.*?'))?
如果你能提供一些样本数据或更详细地解释主题的样子,这种模式可能会得到改善。例如,所有的数字都在单独的一行上(就像你的模式所建议的那样),还是它们是文本的一部分?
示例脚本和解释的模式:
$string = <<<EOT
123-456-7890
123-456-7890 Ext. 321
123-456-7890 Ext. 4321
(123) 456-7890
lorem ipsum
123-456-7890 (Text)
123.456.7890
foo bar baz
EOT;
//preg_match_all("/((?:'d{3}[.-]|'('d{3}')'s+)'d{3}[.-]'d{4})(?:'s+Ext'.'s+('d+)|'s+'(.*?'))?/i", $string, $matches);
preg_match_all("/
( # open capturing group to hold the phone number
(?: # open non-capturing group
'd{3}[.-] # match 3 digits followed by a . or -
| # OR, if the previous part of this group did not match
'('d{3}')'s+ # match 3 digits between parentheses folowed by one or more spaces
) # close non-capturing group
'd{3}[.-] # match 3 digits followed by a . or -
'd{4} # match 4 digits
) # close capturing group
(?: # open non-capturing group
's+Ext'.'s+ # one or more spaces followed by Ext. followed by one or more spaces
( # open capturing group to hold the extension number
'd+ # match one or more digits
) # close capturing group
| # OR, if the previous part of this non-capturing group did not match
's+'(.*?') # one or more spaces and then anything, except newline, between (the smallest) pair of parentheses
)? # close non-capturing group, the ? makes the whole non-capturing group optional
/ix", $string, $matches);# the i flag makes the matches case insensitive and x allows for the comments and spacing
echo "<pre>'n";
print_r($matches);
输出:
Array
(
[0] => Array
(
[0] => 123-456-7890
[1] => 123-456-7890 Ext. 321
[2] => 123-456-7890 Ext. 4321
[3] => (123) 456-7890

)
)
对于另一行,上面的模式也会与那一行匹配,但如果你确实需要它,它是
$string = "123-456-7890 (Text & Special Chars.); 123-456-7890 (Text)";
preg_match_all("/('d{3}[.-]'d{3}[.-]'d{4})'s+'(.*');'s+('d{3}[.-]'d{3}[.-]'d{4})'s+'(.*?')/i", $string, $matches);
echo "<pre>'n";
print_r($matches);
输出:
Array
(
[0] => Array
(
[0] => 123-456-7890 (Text & Special Chars.); 123-456-7890 (Text)
)
[1] => Array
(
[0] => 123-456-7890
)
[2] => Array
(
[0] => 123-456-7890
)
