These aren't functions, they arrays. You could look at them like this,
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" >
<input type='text' name='aname' />
<input type='text' name='age' />
<input type='submit' name='submit' />
<br><br><br>
<?php
if(isset($_POST['submit']))
{
foreach($_POST as $key => $value)
{
# $this->$key = $value;
echo "$key = $value<br>\n";
}
}
?>
</form>
If you enter "hello" and "45" it will output
aname = hello
age = 56
submit =
