无法从php中访问全局数组 - Not being able to access global array from in php

Not being able to access global array from in php

本文关键字：访问全局数组 php | 更新日期: 2023-09-27

我在一个wordpress主题中有以下情况，我想在一个名为navigation.php的文件中修改

$array_test = array (1,2,3,4);
function func1()
{
  global $array_test;
  echo "test"; // to ensure that the function has been called
  echo $array_test[2]; // this writes nothing, though the function is being called
}

在header.php文件中，函数func1正在被调用，但$array_test[2]的值仍然无法访问，

你有什么想法吗?

编辑:我怀疑这是wordpress或主题的问题，但我不确定主题是免费的health_care_wp_theme

在navigation.php中(如果该文件中没有类，则定义一个)

class Nav
{ 
     public $array_test = array(1,2,3,4);
     public function func1()
     {  
       echo "test"; // to ensure that the function has been called
       return $this->array_test[2]; 
     }
     public function access_within_class()
     {   
       print_r($this->array_test); 
     }     
}

在header。php

include 'path/to/navigation.php';
$nav = new Nav();
$the_array = $nav->func1(); 
echo $the_array;
