 * Hello,
    I’m experiencing a problem with the following snippet : It works properly
   as a script (case 1) but when I put the exact same code into a function body,
   it always prints the same id (case 2) !
 * Case 1 code :
 *     ```
       <?php
       require('./wp-blog-header.php');
   
       function br()
       {
       	echo '<br />'.'--------------------------------------------'.'<br />' ;
       }
   
       //return an associative array of all wp int post : master_translation_id => master_translated_modification_date
   
       	$args = array(
           'numberposts'     => 1000,
           'offset'          => 0,
           'orderby'         => 'post_date',
           'order'           => 'DESC',
           'post_type'       => 'post',
           'post_status'     => 'publish' ); 
   
       	$list_master_id_date =array() ;
       	$lastposts = get_posts( $args );
       	foreach($lastposts as $post)
       	{
       		setup_postdata($post);
       		the_title();
       		br();
       		//the_content();
       		the_id() ;
       		br();
       		//var_dump($post) ;
       		$id=the_id();
       		$post_custom_fields= get_post_custom($id) ;
       		var_dump($post_custom_fields);
       		br();
       		//echo 'master_translation_id : '.$post_custom_fields["master_translation_id"][0].'<br>';
       		//echo 'master_translated_modification_date'.$post_custom_fields["master_translated_modification_date"][0].'<br>';
   
       		$list_master_id_date[$post_custom_fields["master_translation_id"][0]]=$post_custom_fields["master_translated_modification_date"][0] ;
       	}
       	//var_dump($list_master_id_date);
   
       	//return $list_master_id_date ;
   
       ?>
       ```
   
 * Case 2 code:
 *     ```
       <?php
       require('./wp-blog-header.php');
   
       function br()
       {
       	echo '<br />'.'--------------------------------------------'.'<br />' ;
       }
   
       //return an associative array of all wp int post : master_translation_id => master_translated_modification_date
       function test()
       {
       	$args = array(
           'numberposts'     => 1000,
           'offset'          => 0,
           'orderby'         => 'post_date',
           'order'           => 'DESC',
           'post_type'       => 'post',
           'post_status'     => 'publish' ); 
   
       	$list_master_id_date =array() ;
       	$lastposts = get_posts( $args );
       	foreach($lastposts as $post)
       	{
       		setup_postdata($post);
       		the_title();
       		br();
       		//the_content();
       		the_id() ;
       		br();
       		//var_dump($post) ;
       		$id=the_id();
       		$post_custom_fields= get_post_custom($id) ;
       		var_dump($post_custom_fields);
       		br();
       		//echo 'master_translation_id : '.$post_custom_fields["master_translation_id"][0].'<br>';
       		//echo 'master_translated_modification_date'.$post_custom_fields["master_translated_modification_date"][0].'<br>';
   
       		$list_master_id_date[$post_custom_fields["master_translation_id"][0]]=$post_custom_fields["master_translated_modification_date"][0] ;
       	}
       	//var_dump($list_master_id_date);
   
       	//return $list_master_id_date ;
       }
   
       test() ;
       ?>
       ```
   
 * Case 1 output :
 *     ```
