pourquoi pour certains fichiers texte cela fonctionne et certains il ne va pas

Question

J'utilise cela pour ouvrir une option de chargement, mais pour certains fichiers texte cela fonctionne et pour certains, il doesnt. s'il vous plaît aider

$fp = fopen($savingFolder.'/'.$fileName, 'r'); 
header('Content-type: '.$savingFolder.'/'.$fileName); 
header('Content-Disposition: attachment; filename="'.$savingFolder.'/'.$fileName.'"'); 
fpassthru($fp); 

Je fait que le fichier est là et le contenu est le même que tout autre fichier .... esprit souffle

Answer 1

Vous devez définir votre type MIME correctement

$fp = fopen($savingFolder.'/'.$fileName, 'r'); 
header('Content-type: '.getMimeType($fileName)); 
header('Content-Disposition: attachment; filename="'.$fileName.'"'); 
fpassthru($fp); 

function getMimeType($file) { 
     // MIME types array 
     $mimeTypes = array(

Answer 2

Je ne peux pas croire que cette ligne est correcte:

header('Content-type: '.$savingFolder.'/'.$fileName); 

Certes, cela devrait être

header('Content-type: text/plain'); 

si vous servez des fichiers texte, et un type MIME approprié autre sinon .

Answer 3

Essayez:

$fp = fopen($savingFolder.'/'.$fileName, 'r'); 
header('Content-type: application/octet-stream'); 
header('Content-Disposition: attachment; filename='.$fileName); 
fpassthru($fp); 

Cela permettra d'assurer votre fichier sera téléchargé. Si vous souhaitez un traitement spécial pour chaque type de fichier, utilisez la fonction getMimeType(ext) que Phill Pafford a publiée ici.
