如何使用PHP显示目录中的图像？

Question

I need to display images from a directory. Currently, two blank images are displayed first before my images are shown.

I was told to put the condition if($files>2), and it seemed to be working

<?php
$dir="imagesbu";
$files=scandir($dir);
if($files)
{
?>
<div class="row">
<?php

foreach($files as $file)
{


?>
<div class="col s6 m3 l3">
<div class="card" style="height:100px; width:150px;">
<div class="card-image">
<img src="imagesbu/<?php echo $file;?>" alt="" style="height:100px; 
width:150px;" >
</div>
</div>
</div>

<?php

}
}
?>
</div>

Answer 1

because you get the first directories:

• (.) current directory
• (..) parent directory

and then get your files
