只顯示前2條結果正在使用foreach

Question

我如何使這個foreach線只經過結果0到1？

<?php foreach ($categories as $forum_category) { ?> 

我不想顯示所有結果只是第2個。

任何幫助，將不勝感激。

Answer 1

foreach (array_slice($categories, 0, 2) as $forum_category){ 
    //do something 
} 

Answer 2

<?php for($i=0;$i<2;$i++){you can do anything with $categories[$i]}?>

或者您可以在foreach語句之前添加參數$i=0和：

$i=0; 
<?php foreach ($categories as $forum_category) { $i++; if($i>2) return }?> 

Answer 3

<?php $i = 0; 
    foreach ($categories as $forum_category) { 
    if($i < 2) { 
     // display result 
    } 
    $i++; 
    } 
?> 

Answer 4

這是一種方法。

<?php 

    $count = 0; 
    foreach ($categories as $forum_category) { 
      if($count == 2) 
       break; 
      else { 
        // Your Code 
      } 
     $count++; 
    } 

?> 

Answer 5

只要保留一個櫃檯。 根據您所提供的有限的結構中，所有我可以建議是：

<?php 
    $categoryNumber = 0; 
    foreach ($categories as $forum_category) { 
     $categoryNumber++; 
     if($categoryNumber > 2){ 
      continue; 
     } 
     //... 
    } 
?> 

Answer 6

for ($i = 0; $i < 2; $i++) { 
    $categories[$i]; 
} 

或

foreach ($categories as $forum_category) { 
    if($i < 2) { 
     $categories[$i]; 
    } 
    $i++; 
} 

或只是

$categories[0]; 
$categories[1]; 

Answer 7

<?php $i = 0; 
    foreach ($categories as $forum_category) { 
    if($i <= 1) { 
     //code 
    } 
    $i++; 
    } 
?> 

Answer 8

試試這個：

$i = 0; 
foreach ($categories as $forum_category) { 
    echo $forum_category; 
    if($i == 1) break; 
$i++; 
}
