My Multidimentional Array

brooky

Howdy folks,

I have the following array which has been parsed out of an XML document.

The array is stored as $feedArray.

How can I echo each product attributes?

Burp. 😃

foreach($feedArray['catalog']['product'] as $product){
	foreach($product as $key => $value){
		echo "$key is ".$value[0]."<br>";
	}
}

Thanks for your reply.

I got this error:

Warning: Cannot use a scalar value as an array in /usr/local/www/vhosts/htdocs/xml/TMP430kyzgglh.php on line 12

Warning: Invalid argument supplied for foreach() in /usr/local/www/vhosts/htdocs/xml/TMP430kyzgglh.php on line 12

This is the code:

<?php
// parsing the filename.xml file for IPAddress and it's owner
   $filename = "feed.xml";
   $xmlC = new XmlC();
   $xml_data = file_get_contents( $filename );

   $xmlC->Set_XML_data( $xml_data );

   echo( "<pre>\n" ); // shows output in browser
   $feedArray = $xmlC->obj_data;

   foreach($feedArray['catalog']['product'] as $product){ 
    foreach($product as $key => $value){ 
        echo "$key is ".$value[0]."<br>"; 
    } 
}


   echo "<hr>";
   print_r($feedArray);
   echo( "</pre>\n" );

   class XmlC
   {
     var $xml_data;
     var $obj_data;
     var $pointer;

 function XmlC()
 {
 }

 function Set_xml_data( &$xml_data )
 {
   $this->index = 0;
   $this->pointer[] = &$this->obj_data;

   $this->xml_data = $xml_data;
   $this->xml_parser = xml_parser_create( "UTF-8" );

   xml_parser_set_option( $this->xml_parser, XML_OPTION_CASE_FOLDING, false );
   xml_set_object( $this->xml_parser, $this );
   xml_set_element_handler( $this->xml_parser, "_startElement", "_endElement");
   xml_set_character_data_handler( $this->xml_parser, "_cData" );

   xml_parse( $this->xml_parser, $this->xml_data, true );
   xml_parser_free( $this->xml_parser );
 }

 function _startElement( $parser, $tag, $attributeList )
 {
   foreach( $attributeList as $name => $value )
   {
     $value = $this->_cleanString( $value );
     $object->$name = $value;
   }
   eval( "\$this->pointer[\$this->index]->" . $tag . "[] = \$object;" );
   eval( "\$size = sizeof( \$this->pointer[\$this->index]->" . $tag . " );" );
   eval( "\$this->pointer[] = &\$this->pointer[\$this->index]->" . $tag . "[\$size-1];" );

   $this->index++;
 }

 function _endElement( $parser, $tag )
 {
   array_pop( $this->pointer );
   $this->index--;
 }

 function _cData( $parser, $data )
 {
   if( trim( $data ) )
   {
     $this->pointer[$this->index] = trim( $data );
   }
 }

 function _cleanString( $string )
 {
   return utf8_decode( trim( $string ) );
 }

   }
//retriving information stored in Address and Owner arrays

$counting=count($xmlC->obj_data->DATA[0]->IP_RECORD); //to find out the number of elements in the array
$IPADDR=""; 
$OWNER="";

for($i=0;$i<$counting;++$i)
   { 
       $IPADDR[$i]=$xmlC->obj_data->DATA[0]->IP_RECORD[$i]->ADDRESS[0];
       $OWNER[$i]=$xmlC->obj_data->DATA[0]->IP_RECORD[$i]->OWNER[0];
   }
?>

Ah I misread the depth of the array.

foreach($feedArray['catalog'] as $catalogue){
	foreach($catalogue['product'] as $product){
		foreach($product as $key => $value){
			echo "$key is ".$value[0]."<br>";
		}
	}
}

If the depth gets even deeper you might want to think about recursion rather than tonnes of foreach()'s 🙂

brooky

Cool thanks.

That still gives me an error but its a great help.

Not sure how to do recursion but I'll try and figure it out. Thanks. 😃

Hmm odd, perhaps I am still reading the array incorrectly. Here's what I see:

<?php
$array = array(
	'catalog' => array(
		0 => array(
			'product' => array(
				0 => array(
					'price' => array(
						9.98
					),
					'artist' => array(
						'test'
					)
				),
				1 => array(
					'price' => array(
						9.98
					),
					'artist' => array(
						'test'
					)
				)
			)
		)
	)
);
foreach($array['catalog'] as $catalogue){
	foreach($catalogue['product'] as $product){
		foreach($product as $key => $value){
			echo "$key is ".$value[0]."<br>";
		}
	}
}
?>

brooky

Hmm...

Your example works wich is wierd...

Maybe the stdClass Object has somehing to do with it??

I cant even get say:

echo $feedArray['catalog'][0]['product'][0]['price']['0'];

to work. 🙁

Shrike

Did you know that Expat (which your class uses) has a native function to create an array from XML data? 🙂

brooky

I had no idea. 😕

I'll look it up over at php.net :p
