限制循环运行在php中的次数 [英] limiting number of times a loop runs in php

问题描述

我有一个foreach循环，我需要限制到前10个项目然后突破它。

我会怎么做呢？

  foreach（$ butters->用户 - >用户为$ user）{
 $ id = $ user-> id ; 
 $ name = $ user-> screen_name; 
 $ profimg = $ user-> profile_image_url; 
回显事物; 
} 
  

请详细解释一下。
如果你想使用foreach，你可以添加一个额外的变量来控制迭代的次数。例如：

  $ i = 0; 
 foreach（$ butters-> user->用户为$ user）{
 if（$ i == 10）break; 
 $ id = $ user-> id; 
 $ name = $ user-> screen_name; 
 $ profimg = $ user-> profile_image_url; 
回显事物; 
 $ i ++; 
} 
  

I have a foreach loop that i need to limit to the first 10 items then break out of it.

How would i do that here?

foreach ($butters->users->user as $user) {
    $id = $user->id;
    $name = $user->screen_name;
    $profimg = $user->profile_image_url;
    echo "things";    
} 

Would appreciate a detailed explanation as well.

解决方案

If you want to use foreach, you can add an additional variable to control the number of iterations. For example:

$i=0;
foreach ($butters->users->user as $user) {
    if($i==10) break;
    $id = $user->id;
    $name = $user->screen_name;
    $profimg = $user->profile_image_url;
    echo "things";  
    $i++;  
}
