访问PHP数组元素 [英] Access PHP array element

问题描述

我很难访问我的PHP数组中的特定项目，该数组是这样创建的: array('expected'=> array('form'，'title'))

I struggle to access specific item within my PHP array, which is created like this array('expected' => array('form', 'title'))

.Array
(
    [expected] => Array
        (
            [0] => form
            [1] => title
        )

)

我想访问第一个数组的标题( expected )以及该数组中元素的值( form 和 title )我尝试了诸如 array_values()或 key 之类的方法，但我从未获得正确的结果.

I would like to access the title of the first array (expected) as well as the value of the element within this array (form and title) I tried methods such as array_values()or key but I never get the right results.

编辑多亏了Aamir，这个问题得以解决.实际上，这是因为我将数组作为参数传递给方法，并且默认情况下将其设置为null.是的，我知道，愚蠢的东西.

EDIT Thanks to Aamir, this problem is solved. In fact, it was because I pass the array as a parameter into a method and I set it to null by default. Yes I know, dumb stuff.

推荐答案

foreach($array as $key => $value){
 echo $key; //expected
 echo $value[0]; //form
 echo $value[1]; //title

 //OR if you have more values then 
foreach ($value as $key1 => value1){
  echo $value1; //form in 1st iteration and title in 2nd iteration
 }}
