Is it normal for开发者_开发问答 the Submit button to show in $_POST data?

I have a form and when I var_dump the $_POST data the submit button is showing up. I'm sure I have never had this before, but, I could also be losing it.

Yes. Submit buttons are regular controls in HTML forms.

The button's value will be transmitted along with the form data.

It is normal and expected. all inputs, (text, button, submit) should be present, except for checkboxes that are off, and disabled fields.

It is normal, because submit button also has it's value atribute like all other input elements (it is a text which you see on the button, like 'OK' or 'Submit')..
