How to Output Messages from PHP page to another?

[olddocks]

what is the best way to output error messages from one page to another?

i currently send the messages to display using header() with GET

[PHP]header("Location: /file.php?msg=Invalid Login)[/PHP]

Is there any good workarounds? or a standard way of doing it?

I've done it two different ways.
on the first page that produces the error I will do something along the lines of
[PHP]

if(//whatever produces your error)
{
print "Invalid Input";
include 'file.php';
}[/PHP]

OR

the other way would be to do something like this on the first page.
[PHP]// assign it to a variable like
$errormsg ="Invalid Input";
// add it to a hidden variable
print "<input type='hidden' value=$errormsg name='message'>
[/PHP]

then on the second page
[PHP]$errormsg = $_POST['message']; //to get the value from the posted page
print $errormsg; //to print the message[/PHP]

to output the message to the other page try to look the $_REQUEST
