传递URL中的数据与使用GET通过表单提交

Question

I have written a small php (test.php) that reads and displays the data passed to it.

<?php $name = $_GET['name']; echo $name;?>

When I execute the following URL http://localhost/test.php?name=Géo

The text that gets displayed is: G�o

However, when I submit "Géo" from another webpage:

<form method="get" action="test.php"> <input type="test" name="name"> <input type="Submit"> </form>

the URL changes to http://localhost/test.php?name=G%C3%A9o

and now the correct text is displayed:Géo

In the first scenario, only when I add utf8_encode( $_GET['name']), the correct text (Géo) gets displayed.

My question: Is it possible to know how the data was passed, submitting via a form or directly from the URL. If not then what changes should I make to the webpage so that both the scenarios are handled correctly i.e. display Géo in both the cases.

Thanks for your help.

Answer 1

You can add a reg. expression that will check if the parameter contain %. Because that the encoded parameter probably contains a %.

But, if you'll execute url that for some reason contains a %, the problem will comeback...
