a debug technique enquiry

[vito]

Dear all,

when i add

include('abc.php');

in the last line of 'def.php',

the codes in abc.php were once executed. now after series of changes
(including setting php.ini), i don't know which one makes a bug.

here is the starting lines of abc.php:
<?php
// indicate test version or public version.
// 0: prompt 1: test 2: Web
$type = 2;

print "<h2>Welcome to this page</h2>\n";

exit;

....

the print is to see if it works or not but it even doesn't print out.
permission of abc.php hasn't been changed and every time i run def.php, the
timestamp of abc.php shows an update accordingly.

What can i do in abc.php to debug?

thanks a lot.

Start by fixing the syntax at the end of the file. It's "?>" not simply
">".

a typo only. the original files each have that one.

First of all: You have display errors on, and error_reporting set to E_ALL?

Second, it's probably def.php that needs to be debugged. Try a simple
include file:

<?php print("untill here it works"); ?>
And move it up in your def.php untill it works, the error is somewhere
below.

Cutting out large pieces of code in a copied version untill you can
reproduce the problem with a minimal amount of code is always very
clarifying.

The '?>' is often reduced to '>' by newsreaders, highly probable it was in
the code you sent :-)
