I normally use this to validate user input which can be "empty" but not really empty:
function vazio(&$var){
if (!isset($var)){
return true;
}elseif($var === 0){
return false;
}elseif($var === '0'){
return false;
}elseif($var === false){
return false;
}elseif(trim($var) === ''){
return true;
}elseif($var === NULL){
return true;
}elseif(empty($var)){
return true;
}else{
return false;
}
}
