两次迭代后打破foreach循环 [英] Breaking a foreach loop after two iterations

问题描述

  foreach（$ posttags as $ tags）如何在两次迭代之后制止foreach循环，如下所示： {
 $ tag1 = $ tags-> slug; 
}这是第一次迭代，存储在变量$ tag1 
 
 foreach（$ posttags as $ tags）{
 $ tag2 = $ tags-> slug ; 
} ----这是第二次迭代，存储在变量$ tag2 
 
 brake中; ---制动foreach循环
  

有什么想法？

解决方案

最明显的答案是不使用foreach循环，如果你不想循环每个项目。使用其他循环结构，或者手动抓取第一个和第二个项目，如果这是你真正想要的。

How can I brake a foreach loop after two iterations, something like this:

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

Any ideas?

解决方案

The most obvious answer is not to use a foreach loop if you don't want to loop through each item. Use some other looping structure, or grab the first and second items manually if that's what you really want.
