Php 如何加载上次上载的哪个图像？,php,Php,我正在加载一个jpg图像，但是如果用户上传一个png文件或jpeg文件作为个人资料图像，而他已经有一个jpg文件，该怎么办同名示例：abc@mail.com_profileimage.ext 我通过url直接链接得到这张图片 <img style="width: 100%" src="http://proconstruct.co.in/upload_images/<?php echo $email.'_profileimage.jpg';?>" onerror="this.s

我正在加载一个jpg图像，但是如果用户上传一个png文件或jpeg文件作为个人资料图像，而他已经有一个jpg文件，该怎么办

同名示例：abc@mail.com_profileimage.ext

我通过url直接链接得到这张图片

<img style="width: 100%" src="http://proconstruct.co.in/upload_images/<?php echo $email.'_profileimage.jpg';?>" onerror="this.src = 'http://proconstruct.co.in/images/noimage.jpg'; ">

你需要调用递归函数，请查看此url我了解你的要求，你能不能也发布你的代码。Lalit Sharma:ctime不是创建时间，它的更改时间我需要创建时间用户：有我更新过的代码
