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

Answer 1

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})

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
