foreach($_POST as $index=>$valeur){

can someone explain to me what it means roughly?

for each elements of the array $_POST...

then I am lost

$index => $value just tells the loop to store the key of the post variable into $index and the value of the key into $value

let's say you're $_POST variable looks like so:



and you loop through it with for each printing out the $index and $value for each iteration.



your output would be:

Thanks, that's very clear actually, I appreciate a lot your answer!

Is it possible to use a foreach and still not show the name of the ' submit ' button?

I just want to know if it's possible, I don't want to know how though.

If I'm understanding your question correctly, yes it is

yea, I am talking about the name:

When using foreach it'll show all the previous but since the input submit is a name too, it'll show the index and the value of it since that's what I am telling PHP to do when I write this echo

Well thanks, I just wanted to know if it was possible to remove the submit name and its value, now I will try to figure it out on my own.

I wondered, is there a reason anyone would use $_GET when apparently $_POST is 100 time more secure?

If you want to send someone link to this topic, how would you do it if the forum used POST and not GET?


Also it's not more secure really

After reading that, it's a lot clearer.
