当我尝试在我的网站上为全尺寸图像添加水印时,我在PHP中面临一个非常烦人的问题。水印工作正常几周,但突然间它开始出现这个错误:图片“bla bla”无法显示,因为它包含错误
我查了一切,一切似乎都运转得很好!我被困住了,我不知道该怎么做。
这是我的水印php文件:
require_once "maincore.php"; if (isset($_GET['photo_id']) && isnum($_GET['photo_id'])) { $result = dbquery("SELECT td.*, tc.* FROM ".DB_PRODUCTS." td LEFT JOIN ".DB_PRODUCT_CATS." tc ON td.product_cat=tc.cat_id WHERE product_id='".$_GET['photo_id']."'"); $data = dbarray($result); define("PHOTODIR", BASEDIR."downloads/images/"); $parts = explode(".", $data['product_image']); $wm_file1 = $parts[0]."_w1.".$parts[1]; $wm_file2 = $parts[0]."_w2.".$parts[1]; if (!isset($_GET['full'])) { $wm_file = PHOTODIR.$wm_file1; } else { $wm_file = PHOTODIR.$wm_file2; } header("Content-type: image/jpg"); $img = PHOTODIR.$data['product_image']; $cop = BASEDIR.$settings['photo_watermark_image']; if (preg_match("/.jpg/i", strtolower($img)) || preg_match("/.jpeg/i", strtolower($img))) { $image = imagecreatefromjpeg($img); } else if (preg_match("/.png/i", strtolower($img))) { $image = imagecreatefrompng($img); } else if (preg_match("/.gif/i", strtolower($img))) { $image = imagecreatefromgif($img); $sizeX = imagesx($image); $sizeY = imagesy($image); $image_tmp = imagecreatetruecolor($sizeX, $sizeY); $ica = imagecolorallocate($image_tmp, 255, 255, 255); imagefill($image_tmp, 0, 0, $ica); if ($settings['thumb_compression'] == "gd2") { imagecopyresampled($image_tmp, $image, 0, 0, 0, 0, $sizeX, $sizeY, $sizeX, $sizeY); } else { imagecopyresized($image_tmp, $image, 0, 0, 0, 0, $sizeX, $sizeY, $sizeX, $sizeY); } $tmp = PHOTODIR.md5(time().$img).'.tmp'; imagejpeg($image_tmp, $tmp); imagedestroy($image_tmp); $image = imagecreatefromjpeg($tmp); unlink($tmp); } if (file_exists($cop) && preg_match("/.png/i", strtolower($cop)) && $settings['photo_watermark']) { $image2 = false; $image_dim_x = imagesx($image); $image_dim_y = imagesy($image); $copyright = imagecreatefrompng($cop); $copyright_dim_x = imagesx($copyright); $copyright_dim_y = imagesy($copyright); $where_x = $image_dim_x - $copyright_dim_x - 5; $where_y = $image_dim_y - $copyright_dim_y - 5; imagecopy ($image, $copyright, $where_x, $where_y, 0, 0, $copyright_dim_x, $copyright_dim_y); $thumb_w = 0; $thumb_h = 0; if (!isset($_GET['full'])) { if ($image_dim_x > $settings['photo_w'] || $image_dim_y > $settings['photo_h']) { if ($image_dim_x $image_dim_y) { $thumb_w = $settings['photo_w']; $thumb_h = round(($image_dim_y * $settings['photo_w']) / $image_dim_x); } else { $thumb_w = $settings['photo_w']; $thumb_h = $settings['photo_h']; } } else { $thumb_w = $image_dim_x; $thumb_h = $image_dim_y; } $image2 = imagecreatetruecolor($thumb_w, $thumb_h); if ($settings['thumb_compression'] == "gd2") { imagecopyresampled($image2, $image, 0, 0, 0, 0, $thumb_w, $thumb_h, $image_dim_x, $image_dim_y); } else { imagecopyresized($image2, $image, 0, 0, 0, 0, $thumb_w, $thumb_h, $image_dim_x, $image_dim_y); } imagedestroy($image); } } //create image if ($settings['photo_watermark_save']) { imagejpeg(($image2 ? $image2 : $image), $wm_file); } imagejpeg((isset($image2) && $image2 ? $image2 : $image)); imagedestroy((isset($image2) && $image2 ? $image2 : $image)); if (isset($copyright) && is_resource($copyright)) { ImageDestroy($copyright); } } else { redirect("index.php"); }
请帮助我!谢谢!

php.ini是否设置了display_errors?如果是这样,您的代码可能会发出警告或通知,这些警告或通知会被合并到二进制图像数据中并破坏它。 检查PHP错误日志以获取新条目。
另一种可能性是,包含文件通过在结束的PHP标记下方底部有多个空白行来输出空白。
