[PHP-DEV] Bug #14278 Updated: Analyzed: Probably OCI related? string-int type casting problem for sure!
ID: 14278
User updated by: [EMAIL PROTECTED]
Old Summary: % and / bug with INTEGERs!
Reported By: [EMAIL PROTECTED]
Old Status: Closed
Status: Open
Bug Type: Math related
Operating System: Linux 2.2.19
PHP Version: 4.0.6
New Comment:
After some more investigation on this bug I noticed following:
I have an OCI insert statement executed with a 'RETURNING INTO' clause.
The value which is returned is a oracle DB entry of type NUMBER. I
expected to have the returned value in PHP to be a number as well. BUT
it is a string!
Some more output I produced in my script is:
? echo($num (type: .gettype($num).[.strlen($num).] -
.($num*1).)); ?
The result (when the error occures):
106851 (type: string[6] - 1068514)
As you can see the value of the $num variable changes while automatic
type casting from string to int is executed.
The reason for the NEW (bigger) value is possibly a not null terminated
string value returned by the OCI interface.
My suggestion: While typecasting from string to int an extra check
should be done (e.g. detect if there is a null terminated string and if
not: terminate it).
Thanks for your patch!

No matter how many times I run this script I always get this. Also
tested it on Linux (2.4), with PHP 4.2.0-dev and it works.
Please try a newer version and see if that fixes the problem you're
having. http://www.php.net/~zeev/php-4.1.0RC3.tar.gz or

Sometimes (1 - 10 times a day) I get a strange error on one of my
production servers. See this function:
function MakeHash($num) {
$ret = ;
$ca = array();
for ($i = 0; $i 6; $i++) {
$c = $num % 26;
$ca[] = $num $c;
$ret = sprintf(%c, 65+$c).$ret;
$num = ($num-$c)/ 26;
}
// Send $ca array via email to me (removed)
return $ret;
}
Sometimes calling this function with an INT it calculates wired
results... If that happens I mail the $ca array to myself and see what
it does:
101110 19 (MEANS: 101110 % 26 is 19!? That's wrong, it is 22)
3588 24 (MEANS 101110 / 26 is 3588, but it is 3888)
1495714 12...
57527 15

What goes wrong? In the beginning the % result is wrong, and then the
division result is wrong too... any suggestions!?

[PHP-DEV] Bug #10905: ImageGif (ImagePNG) output uncompressed
From: [EMAIL PROTECTED] Operating system: Linux PHP version: 4.0.5 PHP Bug Type: Output Control Bug description: ImageGif (ImagePNG) output uncompressed Using the compression ob_gzhandler all HTML Pages get compressed well. But dynamic generated Images don't get compressed. Header of the output says, it is compressed, but the data following the header isn't. So those images can't be displayed (by at least netscape) Thanks for the patch, ;-) mike PS: Don't tell me that it isn't useful to gzip images, but if you have switched compression to 'enabled' in your php.ini file and you are creating images on the fly, you'll need it to handle this case correctly. -- Edit Bug report at: http://bugs.php.net/?id=10905edit=1 -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
