Function to load vars?

[aximbigfan]

I made an app in PHP, where a large string of vars is loaded (and can be reloaded in certain instances to validate them).

 

Basically, I want to have a function where vars are loaded, but I don't want them to be global, because they need to stay in the validation functions.

 

So, I know this won't work, but this is what I want to do:

 

INSTEAD of this:

$var1 = $systemvars['var1']
$var2 = $systemvars['var2']
ect.....

 

I WANT to do this:

function load_vars()
{
$var1 = $systemvars['var1']
$var2 = $systemvars['var2']
ect.....
}

function valid()
{
load_vars);
if (isset($var1 ))
echo "hi!";
}

 

Thanks.

sounds like you want to work within a class,

 

though hard to tell based on your question, rather vague

You could use constants if the values don't change.

Pardon my possibly wrong terminology, but constants are basically in the same scope and globals; they can be used anywhere.

 

<?php
define('system_var1', 'valuehere');
//Then to call it..
echo system_var1;  //You don't use $ with constants.  And can't be called from within string, gotta concatenate em...
echo 'System Var1='.system_var1;
?>

I did kind of think about having a class.

 

How do classes work? I can't find a straight explanation.

 

Like I said, it can't be global. The values do change.

foreach will take care of this: http://ca.php.net/foreach

<?php
function load_vars()
{
return array('arg1' => 'Arg 1', 'arg2' => 'Arg 2');
}

function my_sub()
{
extract(load_vars());
echo "$arg1<br>$arg2";
}

my_sub();
?>

So..... Thats how you ret arrays...

One more thing...

 

Say I want to inject this into something:

$var = "var"
$var2 = "var"

 

is there some way I could make just a one line solution to this? For example

 

function test()
{
<one line code to inject var "table" here>

echo $var;

Never mind! Laffin solved my problem in a differnt thread.

 

Basically, I created a var with my vars in it, and when I am ready to parse those vars...

eval($vars);

 

I would hit the "topic solved" button, but I think it ran away  :'(.
