使用ini_set文件定義的最大大小不提交 – user2590163

if(isset($_FILES['uploaded_file'])) { 
    $errors  = array(); 
    $maxsize = 2097152; 
    $acceptable = array(
     'application/pdf', 
     'image/jpeg', 
     'image/jpg', 
     'image/gif', 
     'image/png' 
    ); 

    if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) { 
     $errors[] = 'File too large. File must be less than 2 megabytes.'; 
    } 

    if(!in_array($_FILES['uploaded_file']['type'], $acceptable)) && (!empty($_FILES["uploaded_file"]["type"]))) { 
    $errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.'; 
} 

if(count($errors) === 0) { 
    move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file'); 
} else { 
    foreach($errors as $error) { 
     echo '<script>alert("'.$error.'");</script>'; 
    } 

    die(); //Ensure no more processing is done 
} 
}

試試這個代碼。
