A practical implementation of this function: creating a standardised error-checking process.
// check some fields
if(strlen(trim($username))<3){
$errormessage[]="You need to enter a username";
}else{
$errormessage[]=0;
}
if(strlen(trim($password))<3){
$errormessage[]="You need to enter a password";
}else{
$errormessage[]=0;
}
// check to see if there were any errors (an error-free submission will have a sum of 0)
if(array_sum($errormessage)!=0){
print "error!"; // (I use a separate error display function)
}else{
// no errors found, proceed with submission
}
