Function to load vars in PHP?

[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.

Why the separate vars? Could pass the $systemvars array to the functions that need it.

Because of a function's scope, the array passed (unless passed by reference or globalized) will not be changed outside of the function.



$systemvars['var1'] = 'something';
$systemvars['var2'] = 'isgoingon';

function valid($sysarray) {
if (isset($sysarray['var1']))
echo "hi!";
}

//Call
valid($systemvars);



May or may not be what you need depending on what you're trying to accomplish. (I'm assuming there's more to that function).

This is probably the way you were thinking it:


function SystemVars() {
$sys['var1'] = 'foo';
$sys['var2'] = 'bar';
$sys['var2'] = 'moo';
return $sys;
}

function valid() {
$vars = SystemVars();
if (isset($vars['var1'])) {
echo 'Hi';
}
}


Not that it's going to matter a whole bunch, but that's a function call and array init every time another function calls it. My first example is faster, but we're only talking thousandths of a second so no big diff.

Never mind. I figured it out.


$var = "\$var = \"Hey!!!!!!!\"";
eval($var);
