Initializing lots of numeric variables to 0 -- best way to code?

[mrherman]

If I have a whole bunch of numeric variables that I need to initialize to 0, is there a "wholesale" way of coding this, other than $var1 = 0, $var2=0, etc...

 

Thanks!

What do the variable names look like?

I guess the easiest way would be to use:

 

<?php
$num_of_vars = 10;
$prefix = 'var';

for ($i = 0; $i <= $num_of_vars; $i++) {
  ${$prefix . $i} = 0;
}
?>

Oh, sorry, I was using $var as an example...The actual variables have names of different length, such as...

 

$totalcorrect

$totalitems

$pctcorrect

$appcount

 

I was wondering if you can do something like (although I know this will not work):

 

Store 0 to $totalcorrect, $totalcnt, $....... ;

 

[Wolphie]

The only way to do that would be to make an array which stores the variable names.

 

<?php
$var_name = array('totalcorrect', 'totalitems', 'pctcorrect', 'appcount');

foreach ($var_name as $name) {
  ${$name} = 0;
}
?>

 

So this still involves a bit of manual work.

Wolphie -- that is helpful.  It does help a little.  Thanks!!
