mass feeding with CSV

Greetings

I’m trying to write a class to create post from a csv

I have no problem to turn my csv content into an array

my problem is that while it feeds pretty well the database, I have a problem with the user, it keeps on using the details of the first csv line’s author, while other posts have differents author..

I have tried to unset($_POST[‘user_ID’]) in my for loop.. when I do an echo on the $_POST[‘user_ID’], it shows the correct value, but it look like the wp_write_post(); don’t use it

any idea?

at the bottom part of my code

thank you VERY much in advance

$postFill is my array from my csv

for($i=0;  $i<count($postFill);$i++)
		{

		$_POST['edit_date']=	$postFill[$i][0];	

		$_POST['post_title']= $postFill[$i][2];
		//$_POST['post_title']= $this->cleanInsert($_POST['post_title']);
		$_POST['post_title']=  wp_specialchars( stripslashes( $_POST['post_title'] ));
		$_POST['post_title']= funky_javascript_fix( $_POST['post_title'] );
		$_POST['post_title']= apply_filters( 'default_title', $_POST['post_title'] );

		$_POST['content']=$postFill[$i][3];
		//$_POST['content']= $this->cleanInsert($_POST['content']);
		$_POST['content']= wp_specialchars( stripslashes( $_POST['content'] ));
		$_POST['content']= apply_filters( 'default_content', $_POST['content']);

		$_POST['tags_input'] = $postFill[$i][4];

		$catlist =$postFill[$i][5];
		$metas[toto_name]=$postFill[$i][1];

		$userName =$postFill[$i][6];
		$userUrl =$postFill[$i][7];
		$_POST['user_ID'] = username_exists($userName);
		if (!isset($_POST['user_ID']))
			{
			$userdata = array('user_login' => $userName,'user_pass' => $userPassword, 'user_email' => $userEmail, 'user_url' => $userUrl, 'role' => $userRole);
			$_POST['user_ID'] = wp_insert_user($userdata);
			}

		$_POST['jj']= substr($_POST['edit_date'], 0, 2);
		$_POST['mm']= substr($_POST['edit_date'], 3, 2);
		$_POST['aa']= substr($_POST['edit_date'], 6, 4);
		$_POST['hh']= substr($_POST['edit_date'], 11, 2);
		$_POST['mn']= substr($_POST['edit_date'], 14, 2);
		$_POST['ss']= substr($_POST['edit_date'], 17, 2);

		$_POST['tags_input'] = explode(",", $_POST['tags_input']);

		$categories = explode(",", $catlist);

		$post_ID = wp_write_post();
		echo "the user id is ".$_POST['user_ID']." <br />";

		wp_create_categories($categories, $post_ID);

		if (isset($metas))
			{
				foreach ($metas as $key => $value)
				{
				$_POST['metakeyselect']=$key;
				$_POST['metavalue']=$value;
				add_meta( $post_ID );
				unset($_POST['metakeyselect']);
				unset($_POST['metavalue']);
				}
				unset($value);
				unset($key);
			}

		unset($_POST['user_ID']);
