You have to wait for PHP6 if you need Unicode support.
[2006-09-07 18:46:57] ashabi at yahoo dot com
Description:
When I explode a URL it does not display the hebrew character in my URL
properly.
Reproduce code:
---
$page = explode("/", $_SERVER['PATH_INFO']);
$letter = $page[7];
echo $letter;
$page[7] is a hebrew letter.
Expected result:
For example: à
Actual result:
--
For example: ×
FYI - If I were to use the $_REQUEST function then it would display the
hebrew letter properly.

#38766 [NEW]: Nonbreaking whitespace breaks parsing
From: a at b dot c dot de Operating system: Windows XP SP2 PHP version: 5.1.6 PHP Bug Type: Feature/Change Request Bug description: Nonbreaking whitespace breaks parsing Description: In most (Windows) fonts, character 0xa0 renders as a blank (nonbreaking) space. Some people use text editors that for whatever reason like to use 0xa0 at random locations instead of ordinary spaces. The result is code that _looks_ correct, but when run can trigger a parse error for no apparent reason. In zend_language_scanner.l, 0xa0 is recognised as a LABEL character (which means, among other things, that you could have a variable called "$ ");. Assuming no-one is perverted enough to do something like that, it should be safe to reassign it to WHITESPACE (will this cause grief in other character sets?). Reproduce code: --- Expected result: Hello, World Hello, World Hello, World Hello, World Hello, World Actual result: -- Parse error: parse error, unexpected T_ECHO in C:\test.php on line 5 -- Edit bug report at http://bugs.php.net/?id=38766&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38766&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38766&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38766&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38766&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38766&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38766&r=needtrace Need Reproduce Script:http://bugs.php.net/fix.php?id=38766&r=needscript Try newer version:http://bugs.php.net/fix.php?id=38766&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38766&r=support Expected behavior:http://bugs.php.net/fix.php?id=38766&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38766&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38766&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38766&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38766&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38766&r=dst IIS Stability:http://bugs.php.net/fix.php?id=38766&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38766&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38766&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38766&r=nozend MySQL Configuration Error:http://bugs.php.net/fix.php?id=38766&r=mysqlcfg

doh, submit too quickly
all you have to do:
imagecolortransparent($thumb, 0);
imagealphablending($thumb, false);
the fist to set the bgd color, the second function to keep the alpha
information while copying (no blend ops).
[2006-09-09 22:13:18] [EMAIL PROTECTED]
There is no bug.
You copy an image to a another image. The destination image has no
transparent color defined. True color images are "filled" with black by
default, that's why you see black instead of the transparent color.
short version: all you need to do is:
ImageColorTransparent($thumb, 0);

The bug is in imagecopyresampled() AND imagecopyresized()!!
[2006-09-09 21:45:27] markg852 at hotmail dot com
Description:
This bug can be found when trying to make a thumbnail from a url
(example: http://promote.opera.com/logos/Opera5_t.png) the png isn`t
even transperant anymore unless these 3 lines of code are also added:
$background = imagecolorallocate($thumb, 0, 0, 0);
ImageColorTransparent($thumb, $background); // make the new temp image
all transparent
imagealphablending($thumb, false); // turn off the alpha blending to
keep the alpha channel
i tried everything i could thing of but the quality stays different..
What the code below does is the following:
1. It downloaded the opera logo png image and makes a thumbnail of the
URL!!
2. (after hitting F5) the code will make another thumbnail from the
downloaded full scale image.
3. (after hitting F5 2nd time) the code will show both thumbnails and
look at the quality difference!! and without the 3 lines posted above
the "ugly" image has a black background!!
Reproduce code:
---
';
echo "Thumbnail made from URL";
echo '';
echo "This one is made from a PATH";
exit;
}
elseif (file_exists('./Opera5_t.png'))
{
$filename = 'Opera5_t.png';

There is no bug.
You copy an image to a another image. The destination image has no
transparent color defined. True color images are "filled" with black by
default, that's why you see black instead of the transparent color.

ImageColorTransparent($thumb, 0);

even transperant anymore unless these 3 lines of code are also added:
$background = imagecolorallocate($thumb, 0, 0, 0);
ImageColorTransparent($thumb, $background); // make the new temp image
all transparent
imagealphablending($thumb, false); // turn off the alpha blending to
keep the alpha channel
i tried everything i could thing of but the quality stays different..
What the code below does is the following:
1. It downloaded the opera logo png image and makes a thumbnail of the
URL!!
2. (after hitting F5) the code will make another thumbnail from the
downloaded full scale image.
3. (after hitting F5 2nd time) the code will show both thumbnails and
look at the quality difference!! and without the 3 lines posted above
the "ugly" image has a black background!!
Reproduce code:
---
';
echo "Thumbnail made from URL";
echo '';
echo "This one is made from a PATH";
exit;
}
elseif (file_exists('./Opera5_t.png'))
{
$filename = 'Opera5_t.png';
$mid = 'van_path';
}
else
{
$filename = 'http://promote.opera.com/logos/Opera5_t.png';
$mid = 'van_url';
imagepng(imagecreatefrompng('http://promote.opera.com/logos/Opera5_t.png'),
'Opera5_t.png');
}
$percent = 0.1;
// Get new sizes
list($width, $height) = getimagesize($filename);
$newwidth = $width * $percent;
$newheight = $height * $percent;
// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefrompng($filename);
$background = imagecolorallocate($thumb, 0, 0, 0);
ImageColorTransparent($thumb, $background); // make the new temp image
all transparent
imagealphablending($thumb, false); // turn off the alpha blending to
keep the alpha channel
// Resize
imagecopyresampled($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight,
$width, $height);
// Output
imagepng($thumb, 'thumb_' . $mid . '.png');
echo '';
// Content type

Previous Comments: [2006-09-09 02:05:01] davidb at pins dot net Well, I tried with the latest 5.2b snapshot, and now it's broken for my PC at home also. Appears to be the identical problem - php just silently stops processing after it reads in the POST data, closes the socket, and then waits for the next request, throwing a 500 server error. Please.

I'm currently observing a reproducible version of bug #26647 in the PHP 5.1 train. For a subset of users running mostly Mac but some PC browsers, the PHP process unceremoniously exists witout comment when the form is POST'ed. A truss of the PHP FastCGI process shows PHP reading in the text (incidently, it's also pointed out a performance issue where php's doing a read() of 8 bytes at a time from the FastCGI stream instead of 8kB at at a time, but I digress). The problem appears to go away when I switch to a non-FastCGI version. The broken users are broken consistently - it would be possible (and easy) to gdb trace it and see why it's exiting. Here's the start/end of the truss: accept(0, 0xFFBEDA50, 0xFFBED99C, 1)= 4 fcntl(0, F_SETLK, 0xFFBEDA28) = 0 poll(0xFFBED8F0, 1, 1000) = 0 shutdown(4, 1, 1) = 0 recv(4, "0101\001\0\b\0\0", 8, 0) = 8 recv(4, "\001\0\0\0\0\0\0", 8, 0) = 8 recv(4, "0104\001\015\0\0", 8, 0) = 8 recv(4, "0E05 C O N T E N", 8, 0) = 8 recv(4, " T _ L E N G T H", 8, 0) = 8 recv(4, " 8 3 5 1 90104\0", 8, 0) = 8 recv(4, "01\0 d\0\0\f V C", 8, 0) = 8 recv(4, " O N T E N T _ T", 8, 0) = 8 recv(4, " Y P E m u l t i", 8, 0) = 8 recv(4, " p a r t / f o r", 8, 0) = 8 recv(4, " m - d a t a ; ", 8, 0) = 8 recv(4, " b o u n d a r y", 8, 0) = 8 recv(4, " m L b O u N d A", 8, 0) = 8 (many many lines) recv(4, " r Y - -\r\n0105", 8, 0) = 8 recv(4, "\001\0\0\0\0", 8, 0) = 6 recv(4, 0xFFBEDA28, 8, 0) = 0 close(4)= 0 fcntl(0, F_SETLKW, 0xFFBEDA28) = 0 accept(0, 0xFFBEDA50, 0xFFBED99C, 1) (sleeping...) Bam. Goodbye. No error, no nothing. Reproduce code: --- Expected result: The response.php should work - note, however, that php never even attempts to open the response.php file, which is just a trivial "file uploaded" message, no attempt to save. Actual result: -- See above truss - php just exits. -- Edit this bug report at http://bugs.php.net/?id=38757&edit=1

#38759 [Csd]: PDO sqlite2 empty query causes segfault
ID: 38759
User updated by: jcd+php at psu dot edu
Reported By: jcd+php at psu dot edu
Status: Closed
Bug Type: SQLite related
Operating System: Solaris 9 / Ubuntu Linux 6.06
PHP Version: 5.1.6
New Comment:
Thanks for committing this.
It did seem pretty murky if this was more an SQLite or PHP issue due to
the language used for sqlite_step() in the version 2 API docs on
http://sqlite.org/c_interface.html, section 2.2. Though, I agree
functions should check pointer arguments before dereference. Thanks
again!

This is actually SQLite problem, but I agree, a workaround is
required.
Fixed in 5_2 and HEAD.
[2006-09-09 00:50:45] jcd+php at psu dot edu
Description:
Empty, whitespace and/or comments only query strings passed into the
query method of a PDO object for a 'sqlite2' database appear to cause
segmentation faults. PDO 'sqlite' (SQLite 3) objects appear immune as
does the older sqlite extention (sqlite_query()).
The function pdo_sqlite2_stmt_execute() in
ext/sqlite/pdo_sqlite2.c does not appear to catch a case when
sqlite_compile() returns SQLITE_OK but sets the sqlite virtual machine
pointer to NULL. This seems to occur for empty query strings (0
length, whitespace and/or comments). When passed unchecked into
sqlite_step(), as it appears to be in pdo_sqlite2_stmt_execute(),
sqlite_step() attempts to dereference the pointer, causing a
segmentation fault. The equivalent function (sqlite_query()) in
ext/sqlite/sqlite.c appears to catch this.
This occurs on both:
- Solaris 9, Sun Forte Developer 7 C compiler
- Ubuntu Linux 6.06, gcc 4.0.3 (Ubuntu 4.0.3-1ubuntu5)
Using both PHP versions:
- php-5.1.6
- php5.2-200609072030
The shorter configure line (ubuntu) was:
./configure \
--with-apxs2=/usr/bin/apxs2 \
--prefix=/usr/local/php-5.1.6 \
--with-pdo-sqlite \
--with-sqlite \
--with-libxml-dir=/usr
I triggered it in both mod_php + Apache (1 and 2) and on the command
line. The traces are for the cli.
The solaris version had some php.ini customizations, the ubuntu install
had none.
Reproduce code:
---
query(" ");
?>
Expected result:
Not crash. Either return an error to indicate the fact that the query
was empty or do nothing.
I found that the patch at
http://www.personal.psu.edu/jcd/patches/php-5.1.6_pdo_sqlite2_empty_query.patch
fixed the segfaults for me on both platforms I tested.
Actual result:
--
I can reproduce a segfault with every try. With my patch, I have yet
to trigger a crash.

I think this is a bug because if in a script you open an sqlite query ex: update ... and you start a proc_open the proc_open will have the fd to the db dans the parent process will have a lock on the database. Any childs process must not herit the parent fd's ! I use php cli version and start a lot of process system from an php script parent and all child get all fd's from the parent ( connection to database, files opened ... ). This is not clean because all process are new process started by proc_open and not pcntl_fork. See You.

#38759 [Opn->Csd]: PDO sqlite2 empty query causes segfault
ID: 38759
Updated by: [EMAIL PROTECTED]
Reported By: jcd+php at psu dot edu
-Status: Open
+Status: Closed
Bug Type: SQLite related
Operating System: Solaris 9 / Ubuntu Linux 6.06
PHP Version: 5.1.6
New Comment:
This is actually SQLite problem, but I agree, a workaround is
required.
Fixed in 5_2 and HEAD.
Previous Comments:
[2006-09-09 00:50:45] jcd+php at psu dot edu
Description:
Empty, whitespace and/or comments only query strings passed into the
query method of a PDO object for a 'sqlite2' database appear to cause
segmentation faults. PDO 'sqlite' (SQLite 3) objects appear immune as
does the older sqlite extention (sqlite_query()).
The function pdo_sqlite2_stmt_execute() in
ext/sqlite/pdo_sqlite2.c does not appear to catch a case when
sqlite_compile() returns SQLITE_OK but sets the sqlite virtual machine
pointer to NULL. This seems to occur for empty query strings (0
length, whitespace and/or comments). When passed unchecked into
sqlite_step(), as it appears to be in pdo_sqlite2_stmt_execute(),
sqlite_step() attempts to dereference the pointer, causing a
segmentation fault. The equivalent function (sqlite_query()) in
ext/sqlite/sqlite.c appears to catch this.
This occurs on both:
- Solaris 9, Sun Forte Developer 7 C compiler
- Ubuntu Linux 6.06, gcc 4.0.3 (Ubuntu 4.0.3-1ubuntu5)
Using both PHP versions:
- php-5.1.6
- php5.2-200609072030
The shorter configure line (ubuntu) was:
./configure \
--with-apxs2=/usr/bin/apxs2 \
--prefix=/usr/local/php-5.1.6 \
--with-pdo-sqlite \
--with-sqlite \
--with-libxml-dir=/usr
I triggered it in both mod_php + Apache (1 and 2) and on the command
line. The traces are for the cli.
The solaris version had some php.ini customizations, the ubuntu install
had none.
Reproduce code:
---
query(" ");
?>
Expected result:
Not crash. Either return an error to indicate the fact that the query
was empty or do nothing.
I found that the patch at
http://www.personal.psu.edu/jcd/patches/php-5.1.6_pdo_sqlite2_empty_query.patch
fixed the segfaults for me on both platforms I tested.
Actual result:
--
I can reproduce a segfault with every try. With my patch, I have yet
to trigger a crash.

AFAIK, LFS support is not working properly and IIRC last time I saw
developer response, this is scheduled to be fixed only in PHP6.
somebody can correct me If I wrong.
