Regular Expression in PHP to extract all possible combination of phone/mobile numbers using one Regex

Question

i am using php and wants to extract phone/mobile numbers from string, i have string with multiple format of phone numbers like

$str = '(123) 456-7890 or (123)456-7890 and 1234567890 test "123.456.7890" another test "123 456 7890"';

i had write one RE as,

$phoneMatches = '';
$str = '(123) 456-7890 or (123)456-7890 or 1234567890 or "123.456.7890" or "123 456 7890"';
$phonePattern = '/\b[0-9]{3}\s*[-]?\s*[0-9]{3}\s*[-]?\s*[0-9]{4}\b/';
preg_match_all($phonePattern, $str, $phoneMatches);
echo "<pre>";
print_r($phoneMatches);
exit;

but it gives me output like this,

Array
(
    [0] => Array
        (
            [0] => 1234567890
            [1] => 123 456 7890
        )
)

Means only two, but i want all the possible combination of phone numbers and mobile numbers from string of text by using only ONE Regular expression.

Thanks

Only from *this string of yours*? Or are there any other test cases? Note you forgot to match optional `(` and `)` (and the `.`, I guess) — Wiktor Stribiżew, Oct 13 '16 at 09:43
i think you can follow this http://stackoverflow.com/questions/123559/a-comprehensive-regex-for-phone-number-validation — Ashok Chandrapal, Oct 13 '16 at 09:43
Ok, try [`'/(?:\b|$)[0-9]{3}$?\s*[.-]?\s*[0-9]{3}\s*[.-]?\s*[0-9]{4}\b/'`](https://ideone.com/XftZDP). — Wiktor Stribiżew, Oct 13 '16 at 09:44
thanks @Wiktor Stribiżew, It works for me, can it handle other possible combinations? — Dr Magneto, Oct 13 '16 at 09:48
:) I do not know, you have not provided other scenarios, nor the actual pattern specs. — Wiktor Stribiżew, Oct 13 '16 at 09:50
ok can you pls modify it to extract phone/mobile numbers with any country code ? Thanks — Dr Magneto, Oct 13 '16 at 09:52

I know I'm late, and I'm not sure if this is what you wanted, but I came up with this solution:

[+()\d].*?\d{4}(?!\d)

Demonstration: regex101.com

Explanation:

[+()\d] - We start by matching anything that might represent the start of a phone number.
.*?\d{4} - Then we match anything (using a lazy quantifier) until we reach four ending digits. Just a little note: I considered this as a rule, but it might not always apply. You'd then need to modify the regex to include other cases.
(?!\d) - This is a negative lookahead and it means that we don't want any matches followed by a digit character. I used this to avoid some half-matches.

Another observation is that this regex doesn't validate any phone number. You could have anything in between the matches, mainly because of this part: .*?\d{4}. This will work depending on what kind of situation you intend to use it.
