if size of array is greater than 1
提问by livinzlife
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.
我有一个链接集的结尾，但我只想使用一部分，除非数组的大小大于 1。
$closeLink='</a>'.'<a target="_blank" href="'.implode('" rel="lightbox['.
$post->ID.']" class="single_image" title="'.$lightHtml.'<br /><a href="'.
$desclinkurl.'">'.$desclink.'</a>"></a><a href="',$custgalarr).'"
rel="lightbox['.$post->ID.']" class="single_image" title="'.$lightHtml.'<br /><a
target="_blank" href="'.$desclinkurl.'">'.$desclink.'</
a>"></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，下面显示的隔离部分之后的所有内容只需要显示数组 $custgalarr 的大小是否大于 1：
$closeLink='</a>'
I figure I need to use something like this after the closing a tag
我想我需要在关闭标签后使用这样的东西
if (sizeof($custgalarr) > 1){
Help me out, thanks in advance!
帮帮我，先谢谢了！

foreach($words as $v)
{
if(strlen($v) > $limit)
{
return true;
}
}
return false;
}
$txt = "1";
if(!wordlength($txt, 1))
{

}
