// One more cautios way of extracting all input fields at once is: | |
extract( $_POST, EXTR_OVERWRITE, "form_" ); | |
// This way all your input variables will be called $form_foo and $form_bar at least. | |
// Avoid doing that in the global scope - not because global is evil, but because nobody ever cleans up there. | |

// Thanks to Sergej Müller @wpSEO | |
// you know this how you are doing: | |
$username=$_POST["username"]; | |
$age=$_POST["age"]; | |
$age2=$_POST["age2"]; | |
$age3=$_POST["age3"]; | |
// etc. | |
// This is how to initialize the whole Array | |
$expected=array('username','age','city','street'); | |
foreach($expected as $key){ | |
if(!empty($_POST[$key])){ | |
${key}=$_POST[$key]; | |
} | |
else{ | |
${key}=NULL; | |
} | |
} | |
