Error System...simple (I think)

[Anon]

Ok, this is the basic idea I thought of (not really, I saw it in some other scripting a while back). The idea is to have error messages stored in a file or another part of a script. Each error will have its own id (so to speak). I dont remember if the errors were stored in a class, function, or whatever, but when an error occured in a certain script, it would call to that function (or whatever it was), and then it would dynamiclly get the error message.

Something like this:

$num = "2";
if($num = 4)
{
do something here //actual php code would be here
}elseif($num != 4)
{
call error 101 //actual php code would be here
}

Make that error a function. And you can make include it in a different php file. Like so....

Include("error.php");

$num = 2;
if($num = 4) {
echo "nice job";
}
elseif ($num != 4) {
error18();
}

//end

---

//error.php

function error18() {
echo "Error 18: Value was not equal.";
exit();
}

if($num = 4) {

should be

if($num == 4) {

ok, thats the general idea. Now instead of having a function for each error, how could I go about having one function, and have all the different errors under that?

Have one function that takes an argument:

function error($id) {
switch ($id) {
case 1:
print "Error 1: Cannot connect to db";
break;
case 2:
print "Error 2: Could not open file";
break;
default:
print "An unknown error occured";
}
}
