使用PHP从字符串或文件中提取多个电话号码

I have a huge text file that is a copy and paste job from a PDF phone bill. I need to extract each phone number and put it in an array so that I can insert the numbers into a DB table and run some queries on it.

我有一个很大的文本文件，它是从PDF电话费中复制粘贴过来的。我需要提取每个电话号码，并将其放入一个数组中，这样我就可以将数字插入到数据库表中并对其运行一些查询。

I am using preg_match_all to try and match all of the numbers and failing miserably. Here is the code I have:

我正在使用preg_match_all来尝试匹配所有的数字，并不幸地失败。下面是我的代码:

$phone_list = "13:26 [phone] 13:49 [phone] 13:56 [phone] 14:17 [phone] 14:23 [phone] 14:28 [phone] 14:34";
preg_match_all('/^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$/',$phone_list,$matches);

...Which returns nothing. If I shorten the $phone_list to:

…它返回。如果我将$phone_list缩短为:

$phone_list = "[phone]";

...I get a result. What am I missing?

…我得到一个结果。我缺少什么?

Thanks for your help!

谢谢你的帮助!

Remove the anchors ^ and $ - they force the regex to match the entire string.

删除锚点^和$——他们迫使正则表达式匹配整个字符串。

^ means "Assert that the match starts at the start of the string".

^意味着“断言,比赛从字符串的开始”。

$ means "Assert that the match ends at the end of the string".

$表示“断言匹配在字符串的末尾结束”。
