Global variables -- a quick question

[dico]

Hello,

I have a small script with a function... rather than say global $var_a, $var_b; etc.... is there a way i can set all variables to global? Its a small script so I'm not going to get lost in the variables... it would make things a lot easier in this case.

Alternatively, if I have something like $variable[$x][$y], how can I set that as global -- or even pass it to the function?

Thanks,

Depending on the structure of your code, you might try just storing all variables into an array and then you'd simply need to globalize that single array. For example:

$cfg_user = 'blah';
$cfg_pw = 'blah2';
$cfg_db = 'blah3';

function yourFunction() {
global $cfg_user, $cfg_pw, $cfg_db; // etc. etc. takes too long, right?
}

$cfg = array('user' => 'blah', 'pw' => 'blah2', 'db' => 'blah3');

function myFunction() {
global $cfg;

echo $cfg['user']; // blah
echo $cfg['pw']; // blah2
// etc.
}

To globalize items in arrays, just globalize the array itself.

function myFunction($x, $y) {
global $variable;
echo $variable[$x][$y];
}
