            return serverResponseCode; 

        } // End else block 
    } 

}

Und hier ist der PHP-Skript :

<?php
    $file_path = "uploads/";

    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
 ?>

1Alan C. @

Haben Sie sichergestellt, dass der Benutzer apache ( oder welche Benutzer PHP als ausgeführt wird) über Berechtigungen auf das Verzeichnis im angegebenen schreiben $file_path ?

Setzen Sie den folgenden Code in das gleiche Verzeichnis wie die PHP -Skript ist, und besuchen Sie dann es in Ihrem Web-Browser.

<?php

$file_path = 'uploads/';

$success = file_put_contents($file_path . "afile", "This is a test");

if($success === false) {
    echo "Couldn't write file";
} else {
    echo "Wrote $success bytes";
}

?>

Bedeutet dies geben eine Erfolgsmeldung oder eine Fehlermeldung ?

Wenn es gibt eine Fehlermeldung aus und versuchte Änderung der Eigentümer des Verzeichnisses uploads .
