You'd need to put this code in a directory that contains a directory named "images". The directory named "images" also needs to have files in a <code>*.*</code> name format. There are definitely better ways to do what you're trying to do. Such would be using a database that contains all the images that you want to display.

If that doesn't suit what you want to do, you'd have to be much more descriptive. I have no idea what you want to do and all I'm getting from the code you showed us is to render every file in a directory called "images" as an image.

However, if this point of this post was to simply ask "How do I execute PHP?", please do some searching and never bother us with a question like that.

Another thing @zerkms noticed was that your <code>for ..</code> loop starts at iteration 1 (<code>$i = 1</code>). This means that a result in the array will be skipped over.

<pre><code>for ($i = 0; $i &lt; count($files); $i++) {
</code></pre>

This code snippet iterates over the files in the directory images/ and echos their filenames wrapped in <code>&lt;img&gt;</code> tags. Wouldn't you put it where you want the images?

blocks|key|4129665|text|这将放入images文件夹的父目录中的一个PHP文件(例如images.php)中，您将从中列出图像。您还可以使用以下语法来简化循环(并更正它，因为数组索引应该从0开始，而不是从1开始)：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4129666|<?php

This would go into a PHP file (<code>images.php</code> for example) in the parent directory of the <code>images</code> folder you are listing the images from. You can also simplify your loop (and correct it, since array indexes should start at <code>0</code>, not <code>1</code>) by using the following syntax:

<pre><code>&lt;?php
foreach (glob("images/*.*") as $file){
 echo '&lt;img src="'.$file.'" alt="random image"&gt;&amp;nbsp;&amp;nbsp;';
}
?&gt;
</code></pre>

Try this on for size. Comments are self explanatory.

I'm trying to get a webpage to show images but it doesn't seem to be working.

here's the code:

<pre><code> &lt;?php
$files = glob("images/*.*");
for ($i=1; $i&lt;count($files); $i++)
{
 $num = $files[$i];
 echo '&lt;img src="'.$num.'" alt="random image"&gt;'."&amp;nbsp;&amp;nbsp;";
 }
?&gt;
</code></pre>

If the code should work, where do i put it?
If not, is there a better way to do this?

Where do I put this PHP code?

我正在尝试让网页显示图像，但它似乎不起作用。代码如下： <?php$files = glob("images/*.*");for ($i=1; $i<count($files); $i++){ $num = $files[$i]; echo '<img src="'.$num.'" alt="random image">'."&nbsp;&nbsp;"; }?>如果代码可以
