[SOLVED] Get a variable from a function

[jackpf]

Hi all,

Just wondering if it's possible to get a variable from within a function, something like this:

 

<?php
class blah
{
public $blah;
function blah()
{
	$this->blah = $this->blah2()->blah2;
}
function blah2
{
	$blah2 = 'this string should appear in the public var $blah';
}
}
?>

 

But it doesn't seem to work that way - $blah remains empy.

Any ideas on how to do this would be greatly appreciated,

Thanks,

Jack.

I guess I am asking the impossible then...

Variables should be setup within a classes __construct, $blah2 is not a property of the blah2() method. Your code doesn't really make allot of sense.

 

<?php
class blah {
  public $blah;
  function __construct() {
    $this->blah = $this->blah2();
  }
  function blah2 {
    return 'this string should appear in the public var $blah';
  }
}

$blah = new blah;
echo $blah->blah;
?>

Yeah...I know that's how I should do it, but I already have a function which has an array which I'd like to extract without having to modify it.

 

Ahh well, I guess I'll have to re-write it. Thanks anyway.

why not post the code with the array in it and we'll be able to see what the deal is...

I wouldn't want to post my entire code, as it's a super-cool syntax highlighter and someone might nick it

 

Basically , a simplified version is this:

 

<?php
class code
{
	function geshi($code)
	{
		$exist = array(
		'code to be highlighted',
		'more code'
		);
		$replace = array(
		'replacements',
		'more replacements'
		);

		return preg_replace($exist, $replace, $code);
	}
}
?>

 

And I wanted to extract the $exist and $replace arrays to use elsewhere. I took thorpe's advice and got round it by doing this, however:

 

<?php
class code
{
	var $exist, $replace;
	function code() // construct
	{
		$this->exist = array(
		'code to be highlighted',
		'more code'
		);
		$this->replace = array(
		'replacements',
		'more replacements'
		);

		//now I can access the $exist and $replace arrays upon calling the class
	}
	function geshi($code)
	{
		return preg_replace($this->exist, $this->replace, $code);
	}
}
?>

 

It doesn't look as neat, as the actual code is massive, but it works better.

 

So yeah, thanks for your help.
