WordPress清除$ GLOBALS吗？

问题描述：

What I want to do is to include one of my PHP scripts in a Word Press theme. The problem is that after I include the script file I can't access, inside functions in the theme file, variables declared in the script file .

I have created a new file in the theme folder and added the same code as in header.php and if I open that file it works just fine. So as far as I can tell it's something Word Press related.

/other/path/wordpress/wp-content/themes/theme-name/header.php // this is broken
/other/path/wordpress/wp-content/themes/theme-name/test.php   // this works

/var/www/vhosts/domain/wordpress/ ->(symlink)-> /other/path/wordpress/
                                                /other/path/wordpress/wp-content/themes/theme-name/header.php
/var/www/vhosts/domain/include_file.php

Content of: /var/www/vhosts/domain/include_file.php

$global_var = 'global';
print_r($GLOBALS);  // if I open this file directly this prints globals WITH $global_var;
                    // if this file is included in header this prints all the WP stuff WITHOUT $global_var;

Content of: /other/path/wordpress/wp-content/themes/theme-name/header.php require '/path/to/include_file.php';

print $global_var; // this prints 'global' as expected
function test()
{
    global $global_var;
    print $global_var; // this is NULL
}
test();
print_r($GLOBALS); // this prints all the WP stuff WITHOUT $global_var in it

我想要做的是在Word Press主题中包含我的一个PHP脚本。问题是，在我包含脚本文件后，我无法访问，在主题文件中的内部函数，脚本文件中声明的变量。 p>

我在主题中创建了一个新文件文件夹并添加了与header.php中相同的代码，如果我打开该文件它就可以正常工作。因此，据我所知，Word Press与之相关。 p>

  /other/path/wordpress/wp-content/themes/theme-name/header.php // this 破坏了
 / other / path / wordpress / wp-content / themes / theme-name / test.php //这个工作
 
 / var / www / vhosts / domain / wordpress /  - ＆gt;（符号链接） -  ＆GT;  / other / path / wordpress / 
 /other /path/wordpress/wp-content/themes/theme-name/header.php
/var/www/vhosts/domain/include_file.php
  code>  
 
 内容：/var/www/vhosts/domain/include_file.php
nn$global_var ='global'; 
print_r（$  GLOBALS）;  //如果我直接打开这个文件，打印全局符号$ global_var; 
 //如果这个文件包含在头文件中，这将打印所有WP内容而不用$ global_var; 
  code>  pre> 
 
  内容：/other/path/wordpress/wp-content/themes/theme-name/header.php
 require'/path/to/include_file.php';
nn  print $ global_var;  //按预期打印'全局'
 
函数测试（）
 
 
 
 \ {
 
 
 
 
 
全局$ global_var; 
打印$ global_var;  //这是NULL 
} 
test（）; 
print_r（$ GLOBALS）;  //这会在其中打印所有没有$ global_var的WP内容
  code>  pre> 
  div>

I'm not promoting the use of $GLOBALS, but anyway... define your variable using:

$GLOBALS['varname'] = 'value';

That should work. I suspect you're not actually in global scope like you think you are. That file is probably being include by a function, in which case you're in function-scope.
