I am using spatie library with xpdf in laravel to fetch pdf information uploaded by user. pdftotext is working for me. I am seperating whatiwant from pdf with colonusing preg_match function of php.

$re = '/\b:\s*\'\K[\w-]+/i';
$str = "Some text as: 'Nerad'";
if (preg_match($re, $str, $match)) {
    echo $match;
}

Suppose my pdf contain same data with multiple times. Like I have one column with team_leader_name . But there can be more than 1 or 2 team leaders for user.

and my data comes into array. i am just looping that array and getting my data with index[] and storing into database.

But if i get same data with 2 times how to recognize them.

PDF demo:

Employee Details

Director's Data Director Name : ABC

Director Address : XYZ

Team leader Info

1. Team leader name : ghi

   Team leader address : kji

2. Team leader name : asx

   Team leader address : kji

3. Team leader name : plk

   Team leader address : kji

Now i have to send director's data into separate table and team leaders data into separate table. Above pdf will convert into text and data will come in below format:

Array
(
    [0] => Array
        (
            [0] => ABC
            [1] => XYZ
            [2] => ghi 
            [3] => kji
            [4] => asx 
            [5] => kji
            [6] => plk 
            [7] => kji
        )

)

Now, I have this much info only. It will be ok If i am not having multiple data of same keywords from pdf. But what if i have duplications in pdf.Is there any other preg_match or other solution. Because my words before colon will not be changed.
