Can anyone help me to convert csv contact to vcard format?

Hello friends,
I need to convert 15 million email contacts immediately. I have all the contacts in csv format. But my client needs it in vcard format. I've been searched all over the internet. I couldn't find a converter or script to convert csv file into vcard format.
I found a site that offering this conversion online. But it is not possible to convert all these 15 million online. So can anyone help me. Or tell me is there any product available online.
Or please give me some ideas to convert it immediately. Thanks to everyone who willing to help me. Waiting for your reply

 

This could be done with PHP.
So you basically need to convert a file, such as

Firstname,Lastname,first@last.com
John,Smith,john@smith.com

Code (markup):

into 2 separate files

BEGIN:VCARD
VERSION:3.0
N:Lastname;Firstname
FN:Firstname Lastname
EMAIL:first@last.com

Code (markup):

and

BEGIN:VCARD
VERSION:3.0
N:Smith;John
FN:John Smith
EMAIL:john@smith.com

Code (markup):

or am I wrong?

 

Yes you are right. Can you give the code?. I'll be very thankful to you

 

<?php
$file = file("contactlist.cvs", FILE_IGNORE_NEW_LINES); // Open the original CVS file (change contactlist.cvs to your filename, keep the quotes)
    foreach ($file as $line) { // Process each line
    $exp = explode(",",$line); // Explode by commas
    $vcard_file = fopen($exp[0]." ".$exp[1].".vcf","w"); // Open VCard file for reading (Format: Firstname Lastname.vcf)
    $vcard_contents = "BEGIN:VCARD
VERSION:3.0
N:$exp[1];$exp[0]
FN:$exp[0] $exp[1]
EMAIL:$exp[2]
END:VCARD"; // That's the block for the VCard file contents
    fwrite($vcard_file,$vcard_contents); // Write contents to VCard file
    fclose($vcard_file); // Close VCard file
}
?>

PHP:

Change the 2nd line, be sure not to process all 15 million lines by once if you don't have plenty of RAM and CPU power.
PS: Running this script requires PHP, since it could also be run as a CLI script (not tested though), you don't necessarily need a web server installed, but just PHP.

EDIT: Here's the CLI version, you only need PHP installed

Thanks dude, I'll check it and tell you the result

 

Okay, feedback would be appreciated!

 

Hey thank you dude. Your code works perfectly. Thankyou once again. It took me 2 hours to convert the whole 30 million contacts. But all my efforts are wasted. I delivered my product. But my client cheated me without making payment. I'm really upset.

 

okies but you now have a ready database of 30 million , use these to send cpa offers and make a million out of that

may be this is the way some idiot buyer learn a lesson

 

Ya, i'll try that
