This is because of this line <code>foreach ( $fullimages as $fimages)</code> which is triggering inner loops.

Since you probably have 3 images and both array hold three items array, loop will run 3 times inside a bigger loop which will also execute 3 times. So you have 9 items.

On your code

<pre><code>foreach ( $fullimages as $fimages) //Because of this loop next statement executes
foreach ( $images as $image) {
 echo "&lt;li&gt;&lt;a class='thumb' href='{$fimages['url']}'&gt;&lt;img src='{$image['url']}' /&gt;&lt;/a&gt;&lt;/li&gt;";
}
</code></pre>

What you probably want is?

<pre><code>foreach ( $fullimages as $k =&gt; $fimages) {
 // ^ Get the index of the array
 echo "&lt;li&gt;&lt;a class='thumb' href='{$fimages['url']}'&gt;
 &lt;img src='{$images[$k]['url']}' /&gt;&lt;/a&gt;&lt;/li&gt;";
 // ^ Use that key to find the thumbnail from $images array
}
</code></pre>

You could use <a href="http://www.php.net/manual/en/control-structures.for.php" rel="nofollow">for</a> and iterate over 

<pre><code>for ($i=0;$i&lt;count($images);$i++){
 echo $images[$i]['url'], $fullimages[$i]['url'];
}
</code></pre>

Or use <a href="http://php.net/array_map" rel="nofollow">array_map</a>

<pre><code>array_map(function($image, $fullimage){
 echo $image['url'], $fullimage['url'];
}, $images, $fullimages);
</code></pre>

blocks|key|811745|text|我建议像这样存储图像：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|811746|$images+=+array(
+'fullpath'+=>+'...'
+'thumbpath'+=>+'...'++++
)|code-block|syntax|javascript|811747|而不是两个独立的数组。只需循环遍历一个数组。|811748|或者使用像next($array)，current($array)这样的迭代器函数来同时迭代两个数组。|offset|length|style|CODE|811749|entityMap^0|0|0|0|5|C|I|F|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]|$K|W|L|X|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

I'd recommend storing images like this:

<pre><code>$images = array(
 'fullpath' =&gt; '...'
 'thumbpath' =&gt; '...' 
)
</code></pre>

instead of two separate arrays. and just loop over one array.

or use iterator functions like <code>next($array)</code>, <code>current($array)</code> to simultaneously iterate over two arrays.

I´m not an advanced php coder so I need some help here.

I´m trying to echo list items with a link pointing to the full image and the thumnail.

This is the desired result:

<pre><code>&lt;li&gt;
 &lt;a href="fullimagepath1"&gt;
 &lt;img src="thumnailpath1" /&gt;
 &lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;
 &lt;a href="fullimagepath2"&gt;
 &lt;img src="thumnailpath2" /&gt;
 &lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;
 &lt;a href="fullimagepath3"&gt;
 &lt;img src="thumnailpath3" /&gt;
 &lt;/a&gt;
&lt;/li&gt;
...
</code></pre>

This is the code I'm using

<pre><code> &lt;?php
 $images = rwmb_meta( 'product_gallery', 'type=image&amp;size=press-thumb' );
 $fullimages = rwmb_meta( 'product_gallery', 'type=image&amp;size=productfull-thumb' );
 foreach ( $fullimages as $fimages)
 foreach ( $images as $image)
 {
 echo "&lt;li&gt;&lt;a class='thumb' href='{$fimages['url']}'&gt;&lt;img src='{$image['url']}' /&gt;&lt;/a&gt;&lt;/li&gt;";

 } ?&gt;
</code></pre>

The problem is that I'm getting the thumbnails but multiplied by the number of real results. If I have 3 thumbnails for my gallery the result will be 9 thumbnails, if I have 5 will get 25.

How can I fix the code?
Thanks in advance!
