检查图像文件名是否存在php循环(Check if Image file name exists php loop)

我的根文件夹/images/filename.here上有多个图像。 图像文件名是这样的(电子邮件): you@gmail.jpgyou@gmail.jpgyou@gmail.jpgyou@gmail.jpg

如果存在me@yahoo.jpgyou@gmail.jpg我的代码只显示一个用户图像:

<? 
$email= $data['payment']['email'];
$receipts = "images/".$email;
     if (file_exists($receipts)) { ?>
                <img src="<?=($receipts)?>" width:"100px" height="50px"/>
                <? } else {
                    echo "no receipt";
    } ?>

这只显示“没有_x ”文件名。 如何使用循环_1_2_3显示用户的其他图像(例如me @ yahoo)...它应显示属于用户的所有图像。


I have multiple images on my root folder /images/filename.here. Image filenames are like this (email): me@yahoo.jpg, me@yahoo_1.jpg, me@yahoo_2.jpg, you@gmail.jpg.

My code on showing only one image of user if exist me@yahoo.jpg and you@gmail.jpg:

<? 
$email= $data['payment']['email'];
$receipts = "images/".$email;
     if (file_exists($receipts)) { ?>
                <img src="<?=($receipts)?>" width:"100px" height="50px"/>
                <? } else {
                    echo "no receipt";
    } ?>

this only show the "without _x" filename. How can I show other images of a user(e.g me@yahoo) using loop _1 ,_2, _3... It should display all images that belong to a user.

最满意答案

info.table.td表示带有类tabletd<info>元素(这是无意义的)。

你可能是指table.info td ,这意味着任何td是一个带有类infotable的孩子。


info.table.td means an <info> element with the classes table and td (which is nonsense).

You probably mean table.info td, which means any td that is a child of a table with the class info.
