Accessing Variables From A Class Function Include

[Coyote6]

Hi,

I was curious if there is a way to access variables that are in an include inside of a class function from within a script that was included inside another class function... Kind of hard to explain but hopefully the example helps. The following example produces an undefined variable: var error in the programming file, which it should as it doesn't have access to the variable. Is there a way to pass that to the next script without making it a global variable or using a definition?

Example:

Data file to include

PHP Code:


$var = 'test'; 


Programming file to include

PHP Code:


echo $var; 


PHP Code:


 class Test {

  public function __construct() {
    self::load_data();
  }

  public function load_data() {
    include 'data-file.php';
  }

  public function process_data() {
    include 'programming-file.php';
  }

}

$test = new Test;

$test->process_data();

Well unfortunately you, as far as I know, need to either declare it in the global scope or use a definition. That doesn't mean you can't use some tricks to make it easier, though. Let's take a look at the not example:

Say your file programming-file.php has three variables:

PHP Code:

<?php

$apples = "fruit";
$oranges = "delicious";
$pasta = "noodle";

?>

In your process_data method you'll need to do:

PHP Code:

<?php

public function process_data() {
     global $apples, $oranges, $pasta;
     include 'programming-file.php';
}

?>

However that doesn't mean you need to spend a bunch of time declaring variables in the global scope. Since I use a custom template system I often need to send output to a file. So what I'll do is store everything in an array. Example:

Instead of the way we saw above, we do this:

PHP Code:

<?php

$globalVars['apples'] = "fruit";
$globalVars['oranges'] = "delicious";
$globalVars['pasta'] = "noodle";

?>

Then all we need to do in process_data is:

PHP Code:

<?php

public function process_data() {
     global $globalVars;
     include 'programming-file.php';
}

?>

Other than that the only thing that I think will accomplish it is something like a register_globals() which is a very insecure method to use.

Hope this helps!

Thanks for the reply... That's what I kind of figured. I was trying to add custom modules into my CMS I made. I will probably do something like that. Possible add this to the Test class just was hoping for another way.

PHP Code:


public function module_vars ($mod_name, $array) {
    $this->mod_vars[$mod_name] = $array;
}
