Switch won't work under 4.2.3

[sde21]

I use the following method for switching between functions within php:

e.g.

<?php
function Step1(){
print "Hello";
print "<a href=?mode=step2>Step2</a>";
}

function Step2(){
print "Hello again";
}

switch ($mode){
case "";
Step1();
break;
case "step2";
Step2();
}

This has worked fine until I started to use PHP versions higher than 4.1.2. Any help would be greatly appreciated as I have no idea why this code no longer works.

in your code :

<?php
...
switch ($mode){
case "";
Step1();
break;
case "step2";
Step2();
}

the case instruction is meant to be followed by : and not ;

Thanks for the prompt reply!! I have tried putting : instead of ; after the case instruction, but the code still does not work. The code will work under 4.1.2 whether there is colon or a semi-colon after the case instruction.

When I define $mode=print2 within the code, the program will go to function step2.

Could it be something to do with the way I am trying to switch case from the hyperlink? i.e. <a href=?mode=step2>Step 2</a>?

I am still confused!

It's probably got very little to do with the switch statement and more to do with the register_globals directive, which is switched off by default in PHP 4.1.x+

<?php
function Step1()
{
	print "Hello";
	print "<a href='?mode=step2'>Step2</a>";
}

function Step2()
{
	print "Hello again";
}

switch ($_REQUEST['mode'])
{
	case "":
		Step1();
		break;
	case "step2":
		Step2();
}

?>

Yes!! That works now. Thank you for taking the time to reply to my post.
