Question

I am in a situation .

My php folder structure is like

UI
  user
    login.php
    logout.php
  jquery
    somejs

  css
    somecss
blah.php
blah.php

Now to import any css ,js or any php file i am using the file path like

localhost/UI/user/index.php  // example  

Now i am trying to define a global variable on any page like

 <?php
    $somevar = "localhost";
    GLOBAL $somevar;
    ?>   

So that i could import any css js like

<?php echo $somevar ;?>/UI/user/index.php  // example  

Problem : It is working on that page only where i declared the variable as GLOBAL

I want to use the variable on each page and don’t want to use include

Is there any other alternative to define a variable for files folder in php ?

Answer 1

You do not declare variable with global. You just make it available within you method or function body even it was set (or using your terminology “declared”) outside of it. So there’s no way to have the variable unless it is declared. And there’s no way to do that without running the PHP code (simplification, but it does not matter here). And code is not coming from nowhere, hence the need of include or require of said code that sets variable.

You may try to use php.ini‘s auto_include_file to have your variables auto-included, but still, the PHP code needs to be used for that.

But you generally doing it wrong. move all global variables into class, set autoloader and access i.e. statically. The code will be much cleaner.
