How to include new line in PHP regex

Question

I have a php script that reads a text file. This text file looks like this.

09/27/17 
3:00p  
sam1, 
sam  
15 
(999) 
999-9999
M:(888) 
888-8888 
17  
09/27/17  
3:30p   
mark1, 
marke  
asd
15 
(777) 
777-7777 
M:(666) 
666-6666 
17

What I need to do is extract the phone number but the problem is the phone number is splitted in two line as you see so

My PHP script:

    $string = ""; 
    $date=array();
    $data1 = file("data.txt"); 
    for($i =0; $i < count($data1);$i++)
 { 
    $data = explode(" ",$data1[$i]); 
    $line = $data[0]; 
    //$string .=$line; 

    if (preg_match('^[M:]\([0-9]{3}\)[0-9]{3}-[0-9]{4}/s^',$line)) {
        $string .= $line."\n"; 
    }

    if (preg_match('^\([0-9]{3}\)[0-9]{3}-[0-9]{4}/s^',$line)) {
        $string .= $line."\n"; 
    }

 }

I need it to be like so:

   (999)999-9999,M:(888)888-8888  
   (777)777-7777,M:(666)666-6666

but I am not getting any result because the regex is not valid

What is the correct regex to achieve this? thanks

Try this Regex. The required mobile number can be formed by concatenating what is present in Group1 and Group2 of each of these matches.

^((?:M:)?\(\d{3}\))\s*(\d{3}-\d{4})

Click for Demo

Explanation:

((?:M:)?\(\d{3}\)) - Capturing group 1
- (?:M:)? - Matches 0 or 1 occurrences of the letter M
- \( - matches ( literally
- \d{3} - matches 3 digits
- \) - matches ) literally
\s* - matches 0 or more white space characters
(\d{3}-\d{4}) - 2nd Capturing group containing the sequence of 3 digits followed by a - followed by another 4 digits

(+1) but consider using anchors as well, it reduces the steps needed dramatically: regex101.com/r/4mU8kv/2

Updated. You are correct. The no. of steps were less when I used the ^ anchor.
