Parsing vCard in php - php

Question

Hi i want to parse vCard format to a array. User may upload vCard 2,1 or vCard 3.0 i should be able to parse it. I just want the email with names in the vCard in to a php array.
i have tried vcardphp.sourceforge.net.
<?php
require("vcard.php");
$cards = parse_vcards(file('sample.txt'));
print_r($cards);
function parse_vcards($lines)
{
$cards = array();
$card = new VCard();
while ($card->parse($lines)) {
$property = $card->getProperty('N');
if (!$property) {
return "";
}
$n = $property->getComponents();
$tmp = array();
if ($n[3]) $tmp[] = $n[3]; // Mr.
if ($n[1]) $tmp[] = $n[1]; // John
if ($n[2]) $tmp[] = $n[2]; // Quinlan
if ($n[4]) $tmp[] = $n[4]; // Esq.
$ret = array();
if ($n[0]) $ret[] = $n[0];
$tmp = join(" ", $tmp);
if ($tmp) $ret[] = $tmp;
$key = join(", ", $ret);
$cards[$key] = $card;
// MDH: Create new VCard to prevent overwriting previous one (PHP5)
$card = new VCard();
}
ksort($cards);
return $cards;
}
?>
Undefined index: ENCODING in H:\www\vcardphp\vcard.php on line 146
Notice: Undefined index: CHARSET in H:\www\vcardphp\vcard.php on line 149
and the sample code given doesnt work at all Too many Undefined index: errors

Answer 1

I would take a look at the open source project vCard PHP. Has worked for me!
http://vcardphp.sourceforge.net/

It's just that the http://vcardphp.sourceforge.net/ sample doesn't work with the given code. You can modify the code to make it work (so it doesn't fail on missing data - first from vbook.php:
See the added: if (!empty($n[*])) $tmp[] = $n[*];
function parse_vcards(&$lines)
{
$cards = array();
$card = new VCard();
while ($card->parse($lines)) {
$property = $card->getProperty('N');
if (!$property) {
return "";
}
$n = $property->getComponents();
$tmp = array();
if (!empty($n[3])) $tmp[] = $n[3]; // Mr.
if (!empty($n[1])) $tmp[] = $n[1]; // John
if (!empty($n[2])) $tmp[] = $n[2]; // Quinlan
if (!empty($n[4])) $tmp[] = $n[4]; // Esq.
$ret = array();
if (!empty($n[0])) $ret[] = $n[0];
$tmp = join(" ", $tmp);
if ($tmp) $ret[] = $tmp;
$key = join(", ", $ret);
$cards[$key] = $card;
// MDH: Create new VCard to prevent overwriting previous one (PHP5)
$card = new VCard();
}
ksort($cards);
return $cards;
}
And modify the vcard.php parse function to accomodate not having the expected parameters.
function parse(&$lines)
{
while (list(, $line) = each($lines)) {
$line = rtrim($line);
$tmp = split_quoted_string(":", $line, 2);
if (count($tmp) == 2) {
$this->value = $tmp[1];
$tmp = strtoupper($tmp[0]);
$tmp = split_quoted_string(";", $tmp);
$this->name = $tmp[0];
$this->params = array();
for ($i = 1; $i < count($tmp); $i++) {
$this->_parseParam($tmp[$i]);
}
$encoding_defined = array_key_exists('ENCODING', $this->params);
if ($encoding_defined && $this->params['ENCODING'][0] == 'QUOTED-PRINTABLE') {
$this->_decodeQuotedPrintable($lines);
}
$charset_defined = array_key_exists('CHARSET', $this->params);
if ($charset_defined && $this->params['CHARSET'][0] == 'UTF-8') {
$this->value = utf8_decode($this->value);
}
return true;
}
}
return false;
}
