Possible Duplicate:
PHP detecting request type (GET, POST, PUT or DELETE)

I want to display a warning when people submit a form more than one time, and when he use GET to request a page the count variable reset to 0;

I’m using this technique:

<input type="hidden" name="submissioncount" value="<?php echo $subCount; ?>" />

But it seems to me $_GET and $_POST alway exist:

<?php
if(isset($_GET)){
  $warning = "GET exist";
}else{
  $warning = 'GET not exist';
}
if(isset($_POST)){
  $warning2 = "POST exsit";
}else{
  $warning2 = 'POST not exist ';
}


?>
<!DOCTYPE html>
<html>
<head></head>
<body>
<?php
  echo $warning;
  echo $warning2; 
?>
<form acion='<?php echo $_SERVER['PHP_SELF']?>' method='POST' >
<input type='submit' />
</form>
</body>
</html>

It turns out it aways return exist? Where I did wrong or any other work round for it?

    $_GET and $_POST superglobals exist whether passed or not, so checking for them will return true. Check entries within them to ascertain if they exist.

    if(isset($_POST['submissioncount']) or
    if(isset($_GET[some_GET_variable])

    Alternately,

    $meth = $_SERVER['REQUEST_METHOD'];
if($meth == 'GET')
//do something
else if($meth == 'POST')
//do something else
