[SOLVED] Need some quick help in PHP. :)

[Guest Xanza]

I usually do this kinda stuff where I find something interesting about PHP, and try to replicate it... And recently I got into here-doc - and I came up with this just to test it out and play with it:

 

<?php

class info{
var $name;
var $age;
var $group;

function info(){
	$this->name = "Hello, my name is {$name}, ";
	$this->age = "and I am {$age} year's old";
	$this->group = array("1","2","3","4","5");
	}
}
$info = new info();

echo <<<EOT
{$info->name}{$info->age}, and am in group {$info->group[1]}!
EOT;
?>

 

Then I friggin' realized that I know nothing about classes really... lol! I've been reading up in the php docs but I can't really find a solution to my question, which would be what's the easiest way to add an array to the other two variables that I have in this script: "name" and "age". Any help would be appreciated!

 

Thanks again,

class info{

var $name = array();

var $age = array();

var $group;

That's what I originally had, but unfortunately it dident work.. Any specific reason why?

 

<?php

class info{
var $name = array("Jeff","Ducky","Zach");
var $age = array("18","19","20");
var $group;

function info(){
	$this->name = "Hello, my name is {$name}, ";
	$this->age = "and I am {$age} year's old";
	$this->group = array("1","2","3","4","5");
	}
}
$info = new info();

echo <<<EOT
{$info->name[0]}{$info->age[0]}, and am in group {$info->group[1]}!
EOT;
?>

 

And this outputs: http://xanza.info/test.php

[hansford]

function info($num){

$name = "Hello, my name is " . $this->$name[$num];

$age = "and I am " .  $this->$name[$num] . " year's old";

$this->group = array("1","2","3","4","5");

}

Hmm... it seems your objective here is very strange. You are trying to instanitiate the object with an initiation function that messes with the variables, yet you want to echo a value from an array of which you have changed in the past. Your best idea would be to do the following:

 

<?php

class info
{
var $name   = array ("Jeff", "Ducky", "Zach");
var $age    = array ("18", "19", "20");
var $group  = array ("1", "2", "3", "4", "5");

function info($num)
{
	$this->name = "Hello, my name is ". $this->name[$num] .", ";
	$this->age = "and I am ". $this->age[$num] ." year's old";
	$this->group = $this->group[$num];
}
}

$info = array();
$info[0] = new info(0); // Object 1
$info[1] = new info(1); // Object 2

echo <<<EOT
{$info[0]->name}{$info[0]->age}, and am in group {$info[0]->group}!
EOT;
?>

You are kind of missing the point of a class. Classes allow you to use multiple functions and variables without having to set global values and keep passing variables from function to function.

<?php

class info{
var $name;
var $age;
var $group = array();

function info(){
	$part[] = "Hello, my name is ".$this->name.", ";
	$part[] = "and I am ".$this->age." year's old";
	$part[] = $this->group;
    return $part;
    }
}
// call the class
$info = new info();
// Set your variables
  $info->name = "John";
  $info->age = "32";
  $info->group = array(1,2,3,4,5);
// assign a variable to your class function
  $part = $info->info();

echo <<<EOT
{$part[0]}{$part[1]}, and am in group {$part[2][1]}!
EOT;
?>

Thanks a ton guys, I'm learning tons about classes just from this thread.

If you're using PHP 5, stop using the deprecated syntax that you're currently using.  Use visibility keywords and use the proper constructors and stuff.  (Sorry, I'm pretty strict when I do OOP.  Damned Java and C++. D: )
