move_uploaded_file()返回false.

我的文件是230,000个字符(224 ko)的文本文件

但是,如果我尝试将文件减少到4500个字符,那么效果很好.

是否有最多的字符数？

<?PHP

$host="";
$user="";
$pass="";
//$db = MysqL_connect($host,$user,$pass);
//MysqL_select_db('paul_biaudet',$db);
$DOSsier = 'update-';

$fichier = basename($_FILES['avatar']['name']);

$taille_maxi = 100000;
$taille = filesize($_FILES['avatar']['tmp_name']);
$extensions = array('.txt','.doc');
$extension = strrchr($_FILES['avatar']['name'],'.'); 
//security
if(!in_array($extension,$extensions)) 
{
     $erreur = 'Vous devez uploader un fichier texte';
}
if($taille>$taille_maxi)
{
     $erreur = 'too Big';
}
if($_FILES['avatar']['name']!='Shapes.txt' && $_FILES['avatar']['name']!='routes.txt' ){
    $erreur='...';
}
if(!isset($erreur)) //no error :  upload
{

     $fichier = strtr($fichier,'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ','AAAAAACEEEeiIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy');
     $fichier = PReg_replace('/([^.a-z0-9]+)/i','-',$fichier);
     if(move_uploaded_file($_FILES['avatar']['tmp_name'],$dossier . $fichier)) 
     {
     ...
    }
else 
 {
      echo 'fail';
 }

而且……这是一个失败
