Question

我这里有一个数组但是我想要回显数组中第8个键的single_name，我只是想知道我该怎么做呢？

      $stm_listings_update_options = array (

Answer 1

直接回显数组值

echo $stm_listings_update_options[8]['single_name'];

或循环获取第8个元素

foreach(  $stm_listings_update_options as $key =$value){

  if ($key = 8  ){
      echo $value['single_name'];
  }

}

Answer 2

快速基本方法： echo $stm_listings_update_options[7]['single_name'];

更好：

$i = 7; // Using a variable
$k = 'single_name';
echo $stm_listings_update_options[$i][$k];

我意识到OP可能没有零作为第一个索引。如果数组以'1'作为第一个索引，那么$ i应为8。

Answer 3

$i = 7; // The array to pick data from
foreach(  $stm_listings_update_options as $data){
//if array number is same as $i then echo Slug
if ($data = $i ) {
echo $data["slug"];
}
}

如何在循环中回显特定数组的slug
