php exif_read_data()不是utf-8格式
php exif_read_data()不是utf-8格式
提问于 2018-08-19 03:58:15
所以我使用foreach中的glob()函数来渲染我站点上的文件夹中的图像，我想在里面有标题，所以我把标题放在图像的元数据中，但是当我通过exif_read_data()执行这些元数据时，它将不会以utf-8格式执行，它会显示POL‘T?XE而不是这个POLŠTáŘE。这是我的代码，试图解决这个问题
header("Content-Type: text/html; charset=utf-8");
ini_set('exif.encode_unicode', 'UTF-8');
iconv_set_encoding('input_encoding', 'UTF-8');
iconv_set_encoding('output_encoding', 'UTF-8');
iconv_set_encoding('internal_encoding', 'UTF-8');
$dirs = array_filter(glob('img/*'), 'is_dir');
foreach ($dirs as $dir) {
$files = glob($dir.'/*.{jpg,png,JPG,PNG,jpeg,JPEG}', GLOB_BRACE);
foreach($files as $file) {
$meta_data = exif_read_data($file, 0, true);
echo '
<img src="'.$file.'" title="'.$meta_data['IFD0']['Title'].'" />
';
}
}所有这些都不起作用，即使我使用exiftools。即使是使用utf8_encode()也不能使用mb_convert_encoding($meta_data['IFD0']['Title'], 'UTF-8')。当我使用这个mb_detect_encoding()函数时，它会执行UTF-8。
我尝试使用exiftool将编码设置为utf-8，但也不起作用。你能帮帮我吗?

经过几个小时的字面上寻找答案，没有找到任何东西(没有为我工作)，我想像这样:我把整个正常字母表和特殊字符字母表到该图片的元数据，然后我输出它与$meta_data['IFD0']['Title']到bin2hex()函数，并使和array为每个字母和特殊字母，然后用str_replace替换代码与正常字符。
$hex = array('0000','6100','6200','6300','6400','6500','6600','6700','6800','6900','6a00','6b00','6c00','6d00','6e00','6f00','7000','7100','7200','7300','7400','7500','7600','7700','7800','7900','7a00','4100','4200','4300','4400','4500','4600','4700','4800','4900','4a00','4b00','4c00','4d00','4e00','4f00','5000','5100','5200','5300','5400','5500','5600','5700','5800','5900','5a00','e100','0d01','0f01','e900','1b01','ed00','4801','f300','5901','6101','6501','fa00','6f01','fd00','7e01','c100','0c01','0e01','c900','1a01','cd00','4701','d300','5801','6001','6401','da00','6e01','dd00','7d01','2c00', '2000','3100','3200','3300','3400','3500','3600','3700','3800','3900','3000','2d00','2100','2b00');
$letters = array('', 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','á','č','ď','é','ě','í','ň','ó','ř','š','ť','ú','ů','ý','ž','Á','Č','Ď','É','Ě','Í','Ň','Ó','Ř','Š','Ť','Ú','Ů','Ý','Ž', ',', ' ','1','2','3','4','5','6','7','8','9','0','-','!','+');然后
str_replace($hex, $letters, bin2hex($meta_data['IFD0']['Title']))之前的输出：aY45Y5~1a534Y68Y
输出后：šěř45čř5ž1š53čě4ř6ě8ř (与元数据相同)
注意:即使在$letters示例中，每个字符也必须与$hex中的字符位于相同的位置：
$letters = array('a', 'b', 'c', 'd');
$hex = array('6100','6200','6300','6400'); //'a', 'b', 'c', 'd'页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
