php获取图片的exif信息。
在php语言中，有一个自带的exif_read_data函数可以用来读取图片的exif信息，具体使用方法请参考php手册中的相关内容。
例子：
复制代码 代码示例:
<?php
/**
* 获取图片的exif信息
* edit: www.jb200.com
*/
echo "test1.jpg:<br />n";
$exif = exif_read_data('tests/test1.jpg', 'IFD0');
echo $exif===false ? "No header data found.<br />n" : "Image contains headers<br />n";
$exif = exif_read_data('tests/test2.jpg', 0, true);
echo "test2.jpg:<br />n";
foreach ($exif as $key => $section) {
foreach ($section as $name => $val) {
echo "$key.$name: $val<br />n";
}
}
?>
输出结果：
