php获取图片的exif信息,php自带一个exif_read_data函数可以用来读取图片的exif信息,代码来自php手册

<?php
echo "test1.jpg:
\n"; $exif = exif_read_data('tests/test1.jpg', 'IFD0'); echo $exif===false ? "No header data found.
\n" : "Image contains headers
\n"; $exif = exif_read_data('tests/test2.jpg', 0, true); echo "test2.jpg:
\n"; foreach ($exif as $key => $section) { foreach ($section as $name => $val) { echo "$key.$name: $val
\n"; } } ?>

输出结果如下

test1.jpg:
No header data found.
test2.jpg:
