Problem z zapisem daty Opcje

[RoysoN]

Witam problem dość banalnie, lecz troche trudu przy nim jest:

[PHP] pobierz, plaintext 
date(d.m.Y);
[PHP] pobierz, plaintext 

[PHP] pobierz, plaintext 
<?php 
 
$pole1 = trim($_POST['pole1']); 
$pole2 = trim($_POST['pole2']); 
$pole3 = trim($_POST['pole3']);
 
$pop = date('d-m-Y');
 
if(empty($pole1) and empty($pole2) and empty($pole3)) { 
 
echo '<form action="" method="post"> 
<input type="text" name="pole1" style="width: 200px;" value="Nazwa aktualności" />
<input type="text" name="pole2" style="width: 200px;" value="Treść" />
<select name="pole3">
<option>'.$pop.'</option>
</select>
 
<input type="submit" value="Zapisz" /> 
</form>'; 
}
else { 
 
$dane = $pole1."`".$pole2."`".$pole3."\n"; 
$file = "baza.txt"; 
$fp = fopen($file, "x"); 
flock($fp, 2); 
fwrite($fp, $dane); 
flock($fp, 3); 
fclose($fp);
 
    echo "ZAPISANO!"; 
} 
 
?>
 
<?php 
 
$file = file("baza.txt"); 
foreach($file as $value) { 
$exp = explode("`",$value); 
echo $exp[0]."<br />".$exp[1]."<hr />"; 
} 
 
?>
[PHP] pobierz, plaintext 

Skrypt działał w porządku, dopóki nie dopisalem tam kolejnego pola z datą. wywala mi błąd przy próbie zapisu:
Warning: fopen(baza.txt) [function.fopen]: failed to open stream: File exists in /var/www/sites/yoyo.pl/r/o/rod-karolina/adminzero.php on line 25

Ma ktoś pomysł by rozwiązać ten problem?
