modifying a property of an object from a different class

[The Little Guy]

I have 2 classes:

- Math

- Distance

 

in my math class, I have this line:

$distance = new Distance($this->query, $this->distances);

and this property:

public $special = array();

 

in my Distance class, when it is created, it has a method that is run called "parse". In the parse method, I want to modify the property shown above in Math, and add values to that array. How can I do this?

 

 

Here is a more advanced version of my code:

 

search.php

$math = new Math($_GET['q'], $distances);
print_r($math->special);

I would like to be able to use $math->special in the code above, but the array is empty...

 

In the following code, I create a new distance class within the class.

Math.php

class Math{
public $query = "";
public $result;
public $distances;
public $special = array();
public function __construct($string = "", $dist){
	$this->query = $string;
	$this->distances = $dist;
	$this->result = $this->parse();
}
public function parse(){
	if(preg_match("~(".implode("|", $this->distances).")~", $this->query)){
		// Create a new distance class:
		$distance = new Distance($this->query, $this->distances);
		$this->info = $distance->info;
		return $distance->final;
	}
}
}

 

In the parse method, I would like to modify the special of $math, but I am not sure how, I assume that it is saving it to my $distance instance, instead of my $math instance which I created in search.php how can I modify $math (in search.php) instead of $distance (in Math.php)?

Distance.php

class Distance extends Math{
public $query = "";
public $distances;
public function __construct($string = "", $dist){
	$this->query = preg_replace("~,|\.~", "", $string);
	$this->distances = $dist;
	$this->final = $this->parse();
}
public function parse(){
	preg_match_all("~".implode("|", $this->distances)."~", $this->query, $matches);
	$this->special[0] = $matches[0][0];
	$this->special[1] = $matches[0][1];
}
}

 

I hope all this makes sense, it is hard for me to explain.

 

Thanks!!!
