I've encountered issue with checking $_POST['submit']
if(isset($_POST['submit'])) {}
If the form consists of checkbox/radio and text field, some of my forms can
be submitted by just press [ENTER] at the end of one of the text field. In
this case, the $_POST['submit'] is set even the submit button was not
clicked.
However, in some of my forms, $_POST['submit'] will not be set if I submit
the form by pressing [ENTER] in one of the text field.
So, if the later case happen, I need to remind the user to explicitly click
the [Submit] button.
I don't know why or in what condition that pressing [ENTER] will not submit
the whole form include the $_POST['submit'].

Sorry copied and pasted the wrong line (long day)
if (array_key_exists('username',$_POST))

The best way I've found is to do something like this:
if(isset($_POST['submit']))
{}
Note that in-place of submit you can put the name of any form element. I
chose submit here, because every form should have a submit button. Note
also that this will only work if you have given your submit button a
name:
<input type="submit" name="submit" value="Submit"/>
