Question

I’m trying to insert XML data into mysql database. Issue I’m having is that there are multiple id’s within each tag so my script loads the first only. How do I re-write my script to load all id’s to the db, one id per row.

<?php

 require_once 'db-functions.inc.php' ; //custom database functions

 $xmldata = 'http://api.twitter.com/1/followers/ids.xml?cursor=-1&screen_name=aplusk';
 $open = fopen($xmldata, 'r');
 $content = stream_get_contents($open);
 fclose($open);
 $xml = new SimpleXMLElement($content);

 foreach ($xml->ids as $data) 

 {

 $id = $data->id;

 mysql_query("INSERT INTO data (id) 

 VALUES ('$id')");

 };


 // sample of xml I want to insert
 // <id_list>
 // <ids>
 // <id>275168965</id>
 // <id>28245852</id>
 // <id>15112249</id>
 // </ids>
 // <next_cursor>0</next_cursor>
 // <previous_cursor>0</previous_cursor>
 // </id_list>

Here’s how you should do it:

$xml = new SimpleXMLElement( file_get_contents( 'http://api.twitter.com/1/followers/ids.xml?cursor=-1&screen_name=aplusk' ) );
foreach ( $xml->ids[ 0 ] as $data ) 
{
    echo( $data . "<br>" );
}

It’s not at all intuitive but the ids are hiding inside $xml->ids[ 0 ].
Your SQL statement seems fine.
