 Bug Type:         Scripting Engine problem
 Operating System: Linux Fedora 8
 PHP Version:      5.3.0
 New Comment:

Ok, I aborted trying to use <?= expression ?>. Then I look through your
latest documentation. No mention at all about this change. Finally I
found something in the php.ini file:

short_open_tag = Off

Turned that On and all the tests started working and blank pages were
gone!

Then I looked into you latest 5.3.0 docs again. It says:

List of php.ini directives
[name]            [default]
short_open_tag "1" 

But that's now what got installed. It's default is now Off.

This explains a whole bunch of confused users out there wondering why
they get blank screens!!! 

I would like to very much point out that as you upgrade, it would be in
the very best interest of your users not to get surprised like this.
Please try to keep things backward compatible. I waisted a whole  day on
this and time is $MONEY$. Please DO NOT DEPRECATE old syntax. Keep
moving ahead. Nothing more kills a project than not keeping backward
compatibility.

Your printf() changing with %<before>.<after>f to %<width>.<after> and
no where documenting this has cause trouble for many users. I have to
change EVERY LINE of printf's like that and keep SEPARATE versions for
older host sites that have not upgraded. A real nightmare.

Finally tested your integer wrapping and yes, it does work with 5.3.0.

as you indicated.

You may now close this issue.

I will report a few more bugs that still exist in 5.3.0 as separate
issues.

Ok, still working on this.
I purposely changed php.ini to force error.
Apache definitely reading it.
I also made not accept file type and shows raw PHP code as text on
browser then put back as should be and just get blank page or pieces of
text.

Then, I tried to run the simplist thing with php command line:

---
<html><head></head><body>

<?= "hi<br>" ?>

</body></html>
---

On box with 5.2.4, get this (it works):

# php hi.php
---
<html><head></head><body>

hi<br>
</body></html>
---

On box with 5.3.0 (removed 5.2.4, installed 5.3.0), get this (it does
not work!):

# php hi.php
---
<html><head></head><body>

<?= "hi<br>" ?>

</body></html>
---

BTW, It never did work (when I said sometimes correctly shown - I
accidentally hit the swtich on the working computer and saw it on the
working computer).

Ok, now I will concentrate on just the php command line see why it not 
working with expression  <?= ... ?> ??? is that still valid PHP code or
did that change in 5.3.0??

Hi, I've been trying all day to install 5.3.0 on Fedora 8. Apache
starts up no problem (as it did for 5.2.4). Config looks ok. But output
is mostly blank pages and sometimes shows correct results. But reload
and blank page again. This server still works for all other languages. I
was trying to confirm issue here with latest version but can't get
latest version to work. 5.2.4 worked just before rpm -ev and then rpm
-ivh 5.3.0 rpms. I installed:
php-common-5.3.0-1.fc8.remi.i386.rpm
php-cli-5.3.0-1.fc8.remi.i386.rpm
php-5.3.0-1.fc8.remi.i386.rpm
php-devel-5.3.0-1.fc8.remi.i386.rpm
Resulted in Apache starting without error but complaining about <? when
blank page occurs. But will produce output randomly (even exactly
correct output). Simple test of hello does not work.
Other users on internet complain similarly to blank page problem for
5.3.0.

Here is the simplist I could attach as example:
----
<? error_reporting (E_ALL); ?>
<html><head></head><body>

<?= "hi<br>" ?>

</body></html>
----
Either blank page or 
" ?>
is output.

At first, I thought it was just not mapping .php but the config file
seems ok and syntax chk and module php5_module shows up in apache chk.
/etc/httpd/conf.d was updated with php.conf and so on. 

Puzzled, since 5.2.4 worked a charm just before this install.

Please don't report bugs in ancient versions. We only support the
latest releases.

Ok, I tried that exact code even though results must be same.
That worked on 4.2.2.
That did not work on 5.2.4.
I will download the latest I can find for Fedora 8.
If I can't test 5.3.0, I will get latest Fedora and try again.
Get back to you as soon as I can.

I couldn't find that apparent fix on you lists? Do you know of a fix
that you made? One difference I noted between those 2 versions is that
printf() rounds differently. It now rounds with half-even logic instead
of half-up rounding. Also, it is more in-line with all other languages
now in that your old %5.2f use to mean 5 before, 2 after instead of the
expected (and your now current impl of) 5 is width, with 2 decimal
places after decimal. This good guys, but I couldn't find a note about
this fix. Fortunately my tests picked this up right away.

half-up:   1<-->-->2<-->-->3  (1.5, 2.5 -> always up to 2 and 3)
half-even: 1<-->-->2<--<-->3  (1.5, 2.5 -> even of 2 and 3 -> 2 for
both)

C/C++ on linux uses half-even so you are in-line with C/C++ now. You
must have had some custom printf() thing before.

My point is that you made several changes to some major module? Or is
this related in someway to a new GCC?

Ok, I'll upgrade in steps (first to php5 latest for Fed 8) and then
make another HD with latest Fedora just to confirm what fixes the
issue.

Cheers, Ron Lentjes, LC CLS.

Works for me in 5.3.0

<?php
$n = 2147483647;
$n = (int) ($n + 1);
var_dump($n);
$n = (int) ($n - 1);
var_dump($n);
?>

Produces
int(-2147483648)
int(2147483647)
