I found empty() useful at the beginning of user defined functions, in which I check to make sure any
necessary variables are present before going into any logic. This makes it easier for me to control
some errors.
function foo_bar($var1,$var2){
...if (empty($var1) or empty($var2)){
......echo "You must pass var1 and var2 to this function";
......exit();
...{
...<other logic>
}
Seems to do the job :-)
