如何在两次迭代后中断foreach循环,如下所示:
foreach($posttags as $tags){
$tag1 = $tags->slug;
} --- this is the first iteration, stored in the variable $tag1
foreach($posttags as $tags){
$tag2 = $tags->slug;
} ---- this is the second iteration, stored in the variable $tag2
brake; --- brake the foreach loop
任何想法?
如果不想遍历每个条目,最明显的答案是不要使用foreach循环。使用一些其他的循环结构,或者手动抓取第一和第二项,如果这是你真正想要的。
