我正在努力从摄影师提供给我的客户的JPEG中提取一些信息。
在Windows下检查时,所有图像都包含名为Tags:
的字段中的数据
首先进行一些测试我制作了以下脚本,并使用下面的代码迭代二进制文件头中的条目。
有时我会获得ImageDescription的值。通常是版权和作者中的文本,但标签内容永远不会出现在这里,它是客户最想要自动化的内容的捕获。
有人可以告诉我如何访问Tags字段内容吗?
上传的文件副本为here。
更新 - 将每个Tiger-222的响应更改IDF0更改为ANY_TAG并将第3个arg true 添加到exif_read_data()。还在帖子末尾添加了print_r输出
更新2 添加了请求的error_display()和ini_set()调用,并且还尝试了exif_read_data()第二个arg为0代替每个https://php.net/manual/en/function.exif-read-data.php的“ANY_TAG”
<?php
ini_set('display_errors', 1);
ini_set('exif.encode_unicode', 'UTF-8'); // To see WINXP values
error_reporting(-1);
$n = (intval($_GET['n'])) ? $_GET['n'] : 99;
echo "ANI_$n.jpg:<br />\n";
$exif = exif_read_data("ANI_$n.jpg", 'ANY_TAG', true);
echo $exif===false ? "No header data found.<br />\n" : "Image contains the following headers:<br><br />\n";
if ($exif) {
foreach ($exif as $key => $section) {
if (is_array($section)) {
foreach ($section as $name => $val) {
echo "$key.$name: $val<br />\n";
}
} else {
echo "$key: $section<br>\n";
}
}
}
?>
以下是脚本为who who起重机图像转储的内容:
ANI_69.jpg:

答案 0 :(得分:8)
在三个点(感谢jerrygarciuh的耐心和帮助)。
1)要查看额外信息,只需将第三个参数传递给true
:
$exif = exif_read_data("ANI_$n.jpg", 'IFD0', true);
正如here所解释的那样,它会强制转换为数组以避免各节之间发生冲突。您会在IFD0.Keywords
关键字下找到代码。
WINXP.Keywords
的2) There is an issue。要正确显示这些信息,只需将编码设置为UFT-8:
ini_set('exif.encode_unicode', 'UTF-8');
3)感谢this question from Ferdy,可以使用iptcparse读取Lightroom设置的额外信息。这是完整的脚本:
ini_set('exif.encode_unicode', 'UTF-8'); // To see WINXP values
// Exif informations -- limited by PHP
$exif = exif_read_data("ANI_$n.jpg", 'ANY_TAG', true);
print_r($exif);
// Additionnal informations from Lightroom
getimagesize("ANI_$n.jpg", $infos);
if ( isset($infos['APP13']) ) {
print_r(iptcparse($infos['APP13']));
}
输出:
