我已經使用CodeIgniter爲我的個人網站編寫了一個系統，並根據我的需要使用了GD2庫來處理圖像。在localhost和我用於測試的免費託管時它工作得很好。但是現在我正在從不同的提供商處獲得付費託管服務，它不適用於jpg文件。它顯示了破碎的圖像圖標。但在PNG文件中工作得很好。我試圖顯示操作錯誤，但沒有顯示。CodeIgniter圖像處理JPG錯誤
這是我的媒體控制器，它操縱圖像;
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Media extends CI_Controller
{
function sandbox($imageName , $width)
{
if(!is_file('uploads/sandbox/'.$width.'-'.$imageName)) {
$config['image_library'] = 'gd2';
$config['source_image'] = 'uploads/original/'.$imageName;
$config['new_image'] = 'uploads/sandbox/'.$width.'-'.$imageName;
$config['dynamic_output'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'width';
$config['width'] = $width;
$config['height'] = $width;
$this->image_lib->initialize($config);
return $this->image_lib->resize();
} else {
return true;
}
}
public function covers($imageName)
{
if($this->sandbox($imageName, 920)) {
$config['image_library'] = 'gd2';
$config['source_image'] = 'uploads/sandbox/'.'920-'.$imageName;
$config['dynamic_output'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 920;
$config['height'] = 450;
$this->image_lib->initialize($config);
$this->image_lib->crop();
}

你記得在服務器上安裝GD嗎？我被那一次抓住了。 –
它調整大小並保存到另一個文件（上面的沙箱功能）時工作正常。無論是JPG還是PNG。 – SuperioREX
是自動加載的image_lib庫嗎？如果沒有，那麼在你給他們打電話之前你必須加載庫。我認爲錯誤報告已關閉。嘗試開啓錯誤報告功能 –
