PHP Array - accessing specific elements

本文关键字：元素访问数组 PHP | 更新日期: 2023-09-27

是否有一种方法可以访问php下面的特定数组元素?我试过这些代码，但似乎没有工作:1)数组美元[0]("描述")2)数组->

描述

array (size=5)   'question0' => 
    array (size=7)
      'description' => string 'Lorem ipsum' (length=11)
      'strCorrectResponse' => string 'Lorem ipsum;' (length=11)
      'strStatus' => string 'incorrect' (length=9)
      'strUserResponse' => string 'Lorem ipsum' (length=1)
      'nWeight' => string '1' (length=1)
      'nPoints' => string '0' (length=1)
      'nQuestionNumber' => string '1' (length=1)   'question1' => 
    array (size=7)
      'description' => string 'Lorem ipsum' (length=11)
      'strCorrectResponse' => string 'Lorem ipsum' (length=11)
      'strStatus' => string 'incorrect' (length=9)
      'strUserResponse' => string 'Lorem ipsum' (length=11)
      'nWeight' => string '1' (length=1)
      'nPoints' => string '0' (length=1)
      'nQuestionNumber' => string '2' (length=1)

跟着钥匙进入兔子洞:

$arr = array ('question0' => array('description' => string 'Lorem ipsum' (length=11) 
  |                |                      |
$arr        ['question0']           ['description']

$arr['question0']['description'] => Lorem ipsum
