exactly as included previously:
case_test1.php:
---------------
<?
$i=1;
switch ($i) {
case 0:
print "i equals 0";
break;
case 1:
print "i equals 1";
break;
case 2:
print "i equals 2";
break;
default:
print "i is not equal to 0, 1 or 2";
}
?>
case_test2.php
--------------
<?
for ($i==0; $i<4; %i++)
{
switch ($i) {
case 0:
print "i equals 0";
break;
case 1:
print "i equals 1";
break;
case 2:
print "i equals 2";
break;
default:
print "i is not equal to 0, 1 or 2";
}
}
?>
runnning on win2k pro - sp3 - iis5 (all current security patches)
and just in case it makes any difference, I am NOT running any Zend
compiler/speed products currently

Whilst converting what was turning out to be an increasingly lengthy
and untidy set of IF statements, i found this error. Similar in effect
to http://bugs.php.net/bug.php?id=1812
When a switch case structure is used inside a for loop, the execution
of the PHP script is NULL (or sometimes a page header is created)
example1:
$i=1;
switch ($i) {
case 0:
print "i equals 0";
break;
case 1:
print "i equals 1";
break;
case 2:
print "i equals 2";
break;
default:
print "i is not equal to 0, 1 or 2";
}
this script works correctly and outputs as you would expect. However,
if the switch statement is enclosed in a for loop like so:
for ($i=0; $i<4; $i++)
{
switch ($i) {
case 0:
print "i equals 0";
break;
case 1:
print "i equals 1";
break;
case 2:
print "i equals 2";
break;
default:
print "i is not equal to 0, 1 or 2";
}
}
the script does not seem to execute at all.
I deliberately introduced bad syntax into the program, leaving off
terminating ; and not using $ but the script does not even output
errors. It would appear the the script is not even getting to an error
reporting stage.
This has been tested on 4.2.1 and 4.2.3 versions od PHP
