PHP的理解是新手最难迈过的一道门槛，不过你应该感到幸运的是PHP已经最大极限的为了新手而努力了，如果你学过其他的语言，也许会觉得PHP的确相当的简单，但是如果你之前什么都没学过，那么阿弥陀佛，硬着头皮琢磨吧。 中文体例显示照片EXIF信息，显示图片中所略图 这器材除一些php服装论坛复杂显示三两信息，他人的lb5000服装论坛上看到过显示，asp的也有不外好久没接触看着晕。
不想反复休息，搜过谷歌，除asp没找到其他开源的显示exif的，所以收拾整顿出来也许有效。
没甚么手艺含量，根基只是汉化和材料收拾整顿的任务，以下代码为次要局部，一切文件在紧缩包内，可以普遍用于相册和服装论坛显示图片信息的插件，但愿熟习相干常识的伴侣找找bug或加以优化。
今朝应当缺很多信息，假如单单利用应当足够了。

看到过他人传过去的照片外面有缩略图，Photoshop做的，然而不晓得怎样加出来，有人晓得么
缩略图可以显示：）

兴趣可能会慢慢消亡，所以适当培养兴趣会激发自己无线的乐趣，有了乐趣，编程有啥难的。 |
