";图像损坏或被截断”;PHP调整大小后


"Image corrupt or truncated" after PHP resize

在将图像存储为MySQL中的BLOB之前,我正在尝试调整图像的大小。FireBug告诉我"图像已损坏或被截断",尽管我可以在运行后打开"tmp.jpg"。这是我的代码:

    $fileName = $image['name'];
    $tmpName  = $image['tmp_name'];
    $img_orig = imagecreatefromstring(file_get_contents($tmpName));
    $orig_width = imagesx($img_orig);
    $orig_height = imagesy($img_orig);
    $max_width = $max_height = 500;
    if ($orig_width > $orig_height && $orig_width > $max_width) {
        $new_height = $orig_height/$orig_width*$max_width;
        $new_width = $max_width;
    }
    else if ($orig_height > $max_height) {
        $new_width = $orig_width/$orig_height*$max_height;
        $new_height = $max_height;
    }
    $resized = imagecreatetruecolor($new_width,$new_height);
    imagecopyresampled($resized,$img_orig,0,0,0,0,$new_width,$new_height,$orig_width,$orig_height);
    ImageJPEG($resized,'tmp.jpg', 80);
    $instr = fopen('tmp.jpg', "r+");
    $img = addslashes(fread($instr, filesize('tmp.jpg')));
    $imginfo = getimagesize('tmp.jpg');

在调整大小代码之后,我用以下查询插入MySQL:

$query = sprintf(
        "insert into images (filename, mime_type, file_size, file_data, category, priority)
            values ('%s', '%s', %d, '%s', '%s', 1)",
        mysql_real_escape_string($fileName),
        mysql_real_escape_string($imginfo['mime']),
        filesize('tmp.jpg'),
        mysql_real_escape_string($img),
        mysql_real_escape_string($_POST['category'])
        );

如有任何想法或建议,我们将不胜感激。

首先使用addslashes(),然后使用mysql_real_escape_string(),我认为这会损坏文件数据
