About the parameters of php foreach

Question

Can you give me some detailed explanation about the parameters in foreach? I’m new to PHP and there are a lot of things I don’t understand!

<{foreach item=adv key=key from=$cList.adv}>

 <{if $key!=3}>
           <p class="adsimg"><a target="_blank" href="<{$adv.link}>"><img width="<{$adv.width}> " height="<{$adv.height}>" src="<{$adv.product_pic}>"></a></p>
           <{/if}>
           <{/foreach}>
