Parsing xml with php, children

PHP
1

Hello I successfully created my parser based on this article http://articles.sitepoint.com/article/php-xml-parsing-rss-1-0

Everything is working great except one thing since my xml is formated a little different and I am totally lost on how to assign variable to the children of <photos>.

xml portion

<item>
  <url /> 
  <name /> 
- <photos>
  <photo>1020944_0.jpg</photo> 
  <photo>1020944_1.jpg</photo> 
  <photo>1020944_2.jpg</photo> 
  </photos>
  <user_id /> 
 </item>

PHP code

<?
global $insideitem, $tag, $name, $photos, $user_id;

global $count,$db;

$db = mysql_connect("localhost", "user","pass");
mysql_select_db("db_name",$db);
$result = mysql_query("SELECT user_id FROM table,$db);
while ($myrow = mysql_fetch_array($result)){
$uid=$myrow['user_id'];
$UN_ID[$uid]=$uid;

}



$count=1;
$count2=1;


// ##########################################################
// ************* START ELEMENT FUNCTION *********************
// ##########################################################


function startElement($parser, $name, $attrs) {

global $insideitem, $tag, $name, $photos, $user_id;

if ($insideitem) {
$tag = $name;
} 

elseif($name == "ITEM"){
$insideitem = true;
}

}


function endElement($parser, $name) {

global $insideitem, $tag, $name, $photos, $user_id;

global $count,$count2,$db,$UN_ID;

if ($name == "ITEM") {


if(!$UN_ID[$unique_id]){


$name=addslashes($name);
$photo1=addslashes($photo);
$photo2=addslashes($photo);
$photo3=addslashes($photo);
$photo4=addslashes($photo);
$user_id=addslashes($category);


$sql = "INSERT INTO table 
(
name,
photo1,
photo2,
photo3,
photo4,
user_id
)
 
VALUES 

(
'$name',
'$photo',
'$photo',
'$photo',
'$photo',
'$user_id',
)";



$resultupdate = mysql_query($sql);
}
$name='';
$photos='';
$user_id='';

	
}
}



function characterData($parser, $data) {

global $insideitem, $tag, $name, $photos, $user_id;


if ($insideitem) {

switch ($tag) {

case "NAME":
$name .= $data;
break;

case "PHOTOS":
$photos .= $data;
break;

case "USER_ID":
$user_id .= $data;
break;

}

}

}


$xml_parser = xml_parser_create(); 


xml_set_element_handler($xml_parser, "startElement", "endElement"); 

xml_set_character_data_handler($xml_parser, "characterData"); 

$fp = fopen("../myfile.xml","r") 
       or die("Error reading RSS data."); 


while ($data = fread($fp, 4096)) 

// Parse each 4KB chunk with the XML parser created above 
xml_parse($xml_parser, $data, feof($fp)) 

// Handle errors in parsing 
or die(sprintf("XML error: %s at line %d",  
xml_error_string(xml_get_error_code($xml_parser)),  
xml_get_current_line_number($xml_parser))); 


fclose($fp); 


// ##########################################################
// *********************** FREE MEMORY **********************
// ##########################################################

xml_parser_free($xml_parser);
?>

The number of <photo> tags can range between 1-4. I have tried searching everywhere for info on how to do this and tried everything but I just cant get it. After several days of this giving me headaches I really hope some one can enlighten me.

Hi Fread!

Welcome to Sitepoint Forums!

It would be really easier to parse any types of XML to any depth nodes if you use SIMPLEXML.
