Looks to me like your monitor needs adjusting, and it's just not
showing that column of pixels.
Dink around with the little buttons on your monitor.
You could also try a different font with a fatter [ symbol if it lets
you choose font. Or even just bump the font size up by point.

I think it's more a case of grubby font display in Java apps running on
Mac OS X (leopard at least).
when is the last time you saw a Mac (iMac or MacBook) with dodgy monitor settings?

If it would be a problem caused by the monitor, then the screenshot
would show the brackets!

Samy is correct. I'm able to replicate this on 3 different monitors.
Also, as far as changing the Editor Font and Size in the IDE -- I need

The result type of curl_exec should always be string, except when it
fails, when it's FALSE (bool) (Or maybe it's 0 (int) ??? rtfm)
The error message is not actually part of $result nor gettype. It is
being spewed out to stderr (pipe 2) and splatted to your terminal
screen in the middle of stdout (pipe 1) confusing you, perhaps.
I'm not sure where the 0 and 11 bit is coming from, but if you want
the first part only:
$data = (int) $result;
should get only the first portion of the integral result.

Use yum to remove PHP.
Compile PHP from source; No more yum.
At the ./configure stage, you can use something like:
--with-sqlite=/full/path/to/sqlite/dir/that/has/both/include/and/lib
./configure will "dig down" inside the directory looking for the
"include" dir (headers) and "lib" dir (libraries) in order to compile
in your version of sqlite.
You can also use:
--with-sqlite=shared,/usr/local
(for an example)
and then it builds the sqlite extension "shared" which means it can be
upgraded independently of PHP itself, to save a few minutes' compile
time if sqlite source changes...
This might be good if your sqlite provider is changing it often.
sqlite may be one of the extensions that can NOT be compiled as
"shared" though, for all I know.

You'll need about 3X as much code for proper error checking, but

It's not a new function, really...
It's a new function that didn't work out well, and is deprecated and
only lived from PHP 5.0.0 to PHP 5.0.4
Probably not something you'll want to rely on.

Guys,
I've been asked to build a performance report for a PHP app. I can't profile
it using automated tools as I don't have full access to the server, only to
the application itself.
It's a PHP4 Object-Oriented app, which uses ADODB as abstraction layer with
a Oracle 8i databse. The system also uses a VB.NET socket server for some
data manipulation.
As for migrating to PHP5 I think it's crucial, but I need facts that it
really runs faster than PHP4. Anyone? :)
Any ideas on what might be the bottleneck?
Thanks guys

Try and get a copy of the files and database, then set it up on your
dev machine. Then profile using Xdebug.
If you're looking for comparison numbers maybe look at:
http://sebastian-bergmann.de/archives/745-Benchmark-of-PHP-Branches-3.0-through-5.3-CVS.html
Just FYI, using ADODB will slow down the performance of your app. Any
function calls cost against you and it all adds up.

I have a copy of the files and database, but setting it up is not that
simple. This vb.net is licensed and we don't have license for.
If I could profile the app I'd be more than happy, but that's not going to
happen anytime soon.
Thanks for those numbers, they'll be handy :)
ADODB removal will be studied, thanks for the hint!

Hi Thiago,
I think it depends on what the application does. You can't just point
out a bottleneck just by saying which parts are used.
You can however put little timing functions here and there to measure
which part of an application is taking too long.
Like this:
$s = microtime();
do_some_stuff();
do_some_more_stuff();
$f = microtime();
echo ($f - $s)."\n";
This is very simple benchmarking and you need a lot of these steps to
really get some idea where the bottleneck could be. A good start would
be nearby query execution and results another would be with file access
or remote connections. Also good to investigate are huge loops, huge
arrays that are iterated over etc.
Do this step by step so you are sure which part you are investigating.
Otherwise you have 10 steps, 10 results and you don't know anymore where
to look.
Good luck.

If you remove it, then you remove functionality - so before you go and
rip it out, check whether it's the bottleneck using xdebug.
I use an abstraction layer all the time and the benefits far outweigh
the 'costs'.

Hi Chris,
These 'benefits' you talk about really only matter if you switch your
databases. If this app is written against Oracle and they never plan
to change it, then it isn't a bad idea to cut out that fat and just
deal with the native interface. Even writing wrapper functions that
are very basic that abstract mysql_query or mssql_query end up adding
a lot of overhead over lots of requests. Look at some of the PDO
benchmarks. It is slower than the native functions too because it is
just a wrapper.
Even further if you are writing an app where you care about
performance you should be writing your SQL to the point where it
really isn't portable using all the little vendor specific features so
that you get the most out of it.
From my personal profiling most of my application time is spent in
data access. So the less layers you have there the faster it runs.
But that is just my 2cents on it. :)

Using native functions all over the place, how would you log all the
database queries that a page is running (especially if you don't have
server-level access, only ftp access - ie a clients server on a shared
host) ?
Using wrapper functions/classes it's easy to add an error_log call in to
the 'Query' method to see where everything comes from, and/or how long
each query takes to run.
Obviously that stuff is disabled by default but with a code change it's
doing what you need.

Depends on the app I guess, though I haven't seen an app that vendor
specific (apart from anything to do with full text searching).
Using xdebug is the first step to working out where your real bottleneck
is - I highly doubt it'll be the wrapper class/functions.

What does the vb.net stuff do? Is it the frontend (eg for data-entry) or
is it used on the server-side of things?
Can you profile the php app separate to the vb.net stuff?
First step is usually the database.
Get adodb (either hack it or see if it has an on/off setting for this)
to log all of your db queries and see if any are missing indexes or need
attention.

Hello everyone,
sorry for the crosspost. But recent discussions about:
'[RFC] Replace the flex-based scanner with an re2c [1] based lexer'
revealed one big issue. During the development of said RFC we dropped
--enable-multibyte-support and interaction between engine and ext/mbstring
using declare(encoding=..). Now neither of the two is documented anywhere,
nor does any of the core developers happen to know how it works, what it is
supposed to do or how to test it.
Since we do not want to drop this feature we need some test code, best in
the form of .PHPTs. You can find information on how to write tests here:
http://qa.php.net/write-test.php and
http://talks.somabo.de/200703_montreal_need_for_testing.pdf
If you are interested in this further you are of course also more than
welcome to help in any other form. Apart from the proposal below, there
is also my blog entry to help you getting started:

This may not be exactly what you think, but I didn't know how else to word
the title. I basically need to make a script that will go through every
possible color combination and print them to look just like (or similar) to
the windows color picker. I need it in the format X-Y-Z. For example:
255-255-255
255-254-254
255-253-253
What I have so far is this:
***********************
<?php
$break = print"<br>";
$n1 = "255";
$n2 = "12";
$n3 = "186";
$output = print"
\$drawrect(\$get(color_x),\$get(color_y),\$get(color_w),\$get(color_h),brushColor-$n1-$n2-$n3
penColor-$n1-$n2-$n3)
\$button2(\$get(color_x),\$get(color_y),0,0,\$get(color_w),\$get(color_h),,,PVAR:SET:colorize_global:brushcolor-$n1-$n2-$n3
pencolor-$n1-$n2-$n3,TOOLTIP:\"$n1-$n2-$n3\")
";
$output
?>
***********************
The $drawrect, $button2, and $get are NOT php functions, but to be printed
as actual text (which is why I have escaped them with the backslash).
Anyways, I thought it would be easiest to separate each R-G-B value into its
own variable ($n1, $n2, and $n3). That way I could just use some code
(regex?) to cycle through the numbers 0 to 255.
The HARD part (that I can't seem to even think of a way to make it possible)
is to change JUST the G and B values while keeping the R value at 255. Then
when the G and B values both hit 0, the R value is set to 254 and repeated
until it also hits 0 with the other two. I think (?) that will do every
possible color? I also need to print each string with the individual color
output, and I don't know how to do that either.
In short, I would like something that looks just like the windows color
picker, and when each pixel of it is clicked, it will show me the R-G-B
value in the format I would like.
If anyone understands what I am after,and could help, that would be awesome!

There are plenty of free ones available, try:

But to answer part of your question, this will give you the over
16,000,000 million colors. Example only, I wouldn't run this :-)
for($n1 = 255; $n1 >= 0; $n1 = $n1--) {
$h1 = base_convert($n1, 10, 16);
for($n2 = 255; $n2 >= 0; $n2 = $n2--) {
$h2 = base_convert($n2, 10, 16);
for($n3 = 255; $n3 >= 0; $n3 = $n3--) {
$h3 = base_convert($n3, 10, 16);
echo "$n1-$n2-$n3 ".sprintf("#%06s\n","$h1$h2$h3");
}
}
}
This example will give you the web safe color pallet, 200 and some odd
colors:
for($n1 = 255; $n1 >= 0; $n1 = $n1 - 51) {
$h1 = base_convert($n1, 10, 16);
for($n2 = 255; $n2 >= 0; $n2 = $n2 - 51) {
$h2 = base_convert($n2, 10, 16);
for($n3 = 255; $n3 >= 0; $n3 = $n3 - 51) {
$h3 = base_convert($n3, 10, 16);
echo "$n1-$n2-$n3 ".sprintf("#%06s\n","$h1$h2$h3");
}
}
}

Email editing bug. The first example the loops should be $n1-- , $n2--
, $n3-- , not $n1 = $n1-- , etc...
for($n1 = 255; $n1 >= 0; $n1--) {
$h1 = base_convert($n1, 10, 16);
for($n2 = 255; $n2 >= 0; $n2--) {
$h2 = base_convert($n2, 10, 16);
for($n3 = 255; $n3 >= 0; $n3--) {
$h3 = base_convert($n3, 10, 16);
echo "$n1-$n2-$n3 ".sprintf("#%06s\n","$h1$h2$h3");
}
}

This is a very Bad Idea[tm], because it's going to generate
16,777,216 lines that the browser needs to receive, parse, and
display. This is going to be over 2,516,582,400 bytes (yes, 2.5GB!)
of data to be served. There are several better ways of doing it,
including using an HTML image map that has all of the colors laid-out
by pixel coordinates, reducing the number of colors you want to
display, using Flash, or any number of alternatives.
In any case, here's the code:
<?php
if($_GET['r'] && $_GET['g'] && $_GET['b']) {
if(
!preg_match('/^[0-9]{1,3}$/',$_GET['r'])
|| !preg_match('/^[0-9]{1,3}$/',$_GET['g'])
|| !preg_match('/^[0-9]{1,3}$/',$_GET['b'])
) {
die('Incorrect parameters specified. Please try again.');
} else {
echo "You chose the following:\n";
echo "<b>R</b>: ".$_GET['r']."<br />\n";
echo "<b>G</b>: ".$_GET['g']."<br />\n";
echo "<b>B</b>: ".$_GET['b']."<br />\n";
echo "<br />\n";
}
}
$newline = 63;
for($i=255;$i>0;$i--) {
for($j=255;$j>0;$j--) {
for($k=255;$k>0;$k--) {
echo "<span
style=\"background:rgb(".$i.",".$j.",".$k.");padding:0px;height=5px;width=5px;\">";
echo "<a href=\"?r=".$i."&g=".$j."&b=".$k."\"";
echo "
style=\"color:rgb(".$i.",".$j.",".$k.");\">X</a></span>";
if($newline === 0) {
echo "<br />\n";
$newline = 63;
} else {
echo "\n";
$newline--;
}
}
}
}
?>

I personally found the Sam's "Teach yourself Apache, PHP, MySQL in 24 hours" as a good book to learn and keep around as a reference.

$SESSION is the session variable created with

I don't think it's a change in OO handling, maybe it's a change in the
error_reporting level for the new version and you hadn't noticed the
problem before.
The problem is that $SESSION['cart'] isn't an object - you'll have to
work out why.
It could be that $SESSION['cart'] is getting overridden at some point
with another type of variable.

Its a Fatel Error not a warning. Dont see how level off error
reporting could be relevant.

Fair enough :P
What type of variable is 'cart' when this error happens?
Have permissions been screwed on the session_save_path folder? (check a
phpinfo for where this is if you're not setting it explicitly).

Make sure that you are defining the class before you initialize the session.
I have seen this happen with others on the list, and it has sometimes been that
they are initializing the session, which tries to recreate the object, but the
actual class definition has not happened yet.
make sure you include all your classes before you initialize your session, see
if that works.

I am trying to use this:
imap_setflag_full($imap, $uid, "\\\\Seen", FT_UID) or die("Unable to
mark message as \\Seen");
to mark a message as "read"
It does not seem to have any effect on the return values in
imap_fetch_overview.
Nor does it appear as "read" when I view it with my email client.
The "unseen" count on the mailbox also does not decrease, which I
would expect if it was "working"
Is there some kind of trick I'm missing?
Is there some OTHER flag/function I'm supposed to be using to mark a
message as "Read"? I sure can't find it in tfm so far...
The $imap stream is valid, and I can fetch the headers and body just
fine.
The $uid is from imap_uid and, again, is used to fetch the header and
body just fine.
I've tried imap_close($imap, CL_EXPUNGE) in the hopes that it would
"write" the changes, but no such luck.
PHP 4.4.7 Hardened
Gentoo 2.6.18 hardened R6 SMP
phpinfo says IMAP c-client Version 2004 w/ SSL support enabled
Gentoo says courier-imap 4.0.6-r2 is installed, so probably using that.
The versions are out of my control, due to a security and stability
focus of this install.
