Based on the previous post, I've found this code even more useful:
<?php
function isset_sum(&$var, $val) {
if (isset($var)) $var += $val;
else $var = $val;
}
?>
Now instead of:
<?php
if (isset($foo[$bar][$baz][$fooz])) $foo[$bar][$baz][$fooz] += $count;
else $foo[$bar][$baz][$fooz] = $count;
?>
No more "Undefined variable" warnings, and you save your fingers and sanity! Thanks to
the previous poster for inspiration.
