如果数组的大小大于1。

I have an end of a link set, but I only want a portion to be used UNLESS the size of an array is greater than 1.

我有一个链接集的末尾，但是我只希望使用一部分，除非数组的大小大于1。

$closeLink='</a>'.'<a target=&quot;_blank&quot; href="'.implode('" rel="lightbox['.
$post->ID.']" class="single_image" title="'.$lightHtml.'<br />&lt;a href=&quot;'.
$desclinkurl.'&quot;&gt;'.$desclink.'&lt;/a&gt;"></a><a href="',$custgalarr).'"
rel="lightbox['.$post->ID.']" class="single_image" title="'.$lightHtml.'<br />&lt;a 
target=&quot;_blank&quot; href=&quot;'.$desclinkurl.'&quot;&gt;'.$desclink.'&lt;/
a&gt;"></a>';

So everything after the part shown isolated below needs to only show if the size of the array $custgalarr is greater than 1:

因此，下面显示的独立部分后面的所有内容只需要显示数组$custgalarr是否大于1:

$closeLink='</a>'

I figure I need to use something like this after the closing a tag

我想我需要在结束标签之后使用类似的东西

if (sizeof($custgalarr) > 1){

Help me out, thanks in advance!

先帮我一下，谢谢!
