[PHP] convert a string to integer
Hi, i know this topic is obvious but i have a strange behavior and i'm getting crazy. my stored procedure returns me a string. string can be an email or a message error = '-1', '-2', '-3' when i check if the string contains only digit, i use ctype_digit(mystring) but any way it returns me false... i suppose that for -1, -2, -3 the - is taken as character and not a digit. i tried also to cast it before into integer thanks ctype_digit((int)mystring), but it does not work. so how can i solve this issue ? thx -- Alain Windows XP SP2 PostgreSQL 8.2.4 / MS SQL server 2005 Apache 2.2.4 PHP 5.2.4 C# 2005-2008

Yes and if your script takes .0002 seconds

how many quotes you have of course) :-)
I'm coming in late to this thread so sorry if I missed this :)
How much of a difference would it make if you have something like this:
echo $foo bar bar bar bar $foo $foo; verses: echo $foo . bar bar bar
bar . $foo $foo; ?In other words... You have a large application which
is most likely to be faster? :)
There was a discussion about this a few weeks ago - ISTR that the compiler does
wierd things with double-quoted strings, something like tokenising the words
and
checking each bit for lurking variables.
So in fact
echo $foo bar bar bar bar $foo $foo;
is slowest (because there *are* variables to interpolate,
echo $foo . bar bar bar bar .$foo. .$foo;
is a bit faster, but the double-quoted bits cause some slow-down,
echo $foo . ' bar bar bar bar '.$foo.' '.$foo;
is a bit faster again - the single quoted bits pass through without further
inspection, and finally
echo $foo,' bar bar bar bar ',$foo,' ',$foo;
is actually the fastest, because the strings are not concatenated before
output.
I think that was the overall summary - I can't locate the original post to
verify (or attribute) but it's in this list somewhere...
Cheers

Can you prove these statements with real benchmarks that are current?
Ilia said that it is a myth that there is a performance difference
between and ' in one of his talks.
I found one recent post on the subject in gmane:
http://article.gmane.org/gmane.comp.php.general/169028
The poster's results are as I remembered, except that was building a string, not
echoing: possibly not quite the same.
So I tried it myself, adapting to using echo (to the ob to avaoid printing forty
million * foo bar bar ...). For an extra wheeze, I also tried ?=$foo? syntax
embedded in HTML to see if that is as bad as people make out. I didn't try
HEREDOC syntax, because it is difficult to reproduce exactly the same output -
newlines get added to the output.
To get thing to run I needed to increase time out, and reduce the string to
avoid filling the PHP memory limit I have set at the moment. Here is the code:
?php
ini_set('max_execution_time',300);
$foo = 'f';
ob_start();
$time[1] = microtime(TRUE);
for($x = 0; $x 1000; $x++){
echo $foo b b b b $foo $foo;
}
$time[2] = microtime(TRUE);
ob_end_clean();
ob_start();
$time[3] = microtime(TRUE);
for($x = 0; $x 1000; $x++){
echo $foo . ' b b b b '.$foo.' '.$foo;
}
$time[4] = microtime(TRUE);
ob_end_clean();
ob_start();
$time[5] = microtime(TRUE);
for($x = 0; $x 1000; $x++){
echo $foo . b b b b .$foo. .$foo;
}
$time[6] = microtime(TRUE);
ob_end_clean();
ob_start();

But: 1) I don't find any APC support forum. 2) I don't find any APC error log. I'm browsing Apache error log (with PHP 'E_ALL' activate) and don't see any line about it. Any suggestion is welcome.

Since you've used double quotes, It Should Just Work(TM) ...
$body .=
table
tr
tdimg src=\$myimage1\/td
/tr
/table
;
I'd probably use single-quotes (') around the src attribute to avoid those ugly
backslashes ...
$body .=
table
tr
tdimg src='$myimage1'/td
/tr
/table
;
Might be better in this case to use heredoc syntax ...
$body .EndOfChunk
table
tr
tdimg src=$myimage1/td
/tr
/table
EndOfChunk;

[PHP] Use of callback on a stream
Hello,
I am trying to make a daemon that launches shell commands via proc_open
and gets the stdout of the command via a pipe. The thing is that I would
like to get this stdout via a callback, instead of monitoring the pipe
regularly.
I tried the following code (this is a simplified version of it, but the
callback never gets called,
does anyone know what I forgot ?
Thanks,
Olivier
?php
// First we proc_open a ls
//1 - we build the descriptor array
$descriptorspec = array(
0 = array(pipe, r), // // stdin
1 = array(pipe, w), // stdout
2 = array(pipe, w) // stderr
);
$pipes=array();
// We make a simple callback function
function stream_callback(){
global $pipes;
$stdout_child=stream_get_contents($pipes[1]);
print(Callback received:\n);
print($stdout_child.\n);
}
$context=stream_context_create(array());
stream_context_set_params($context,array('notification' =
'stream_callback'));
$handle=proc_open(/bin/ls
/tmp,$descriptorspec,$pipes,null,null,array('context' = $context));
stream_context_set_params($pipes[1],array('notification' =

[PHP] Use of callback on a stream
Hello,
I am trying to make a daemon that launches shell commands via proc_open
and gets the stdout of the command via a pipe. The thing is that I would
like to get this stdout via a callback, instead of monitoring the pipe
regularly.
I tried the following code (this is a simplified version of it), but the
callback never gets called,
does anyone know what I forgot ?
Thanks,
Olivier
?php
// Php5 used
// we build the descriptor array
$descriptorspec = array(
0 = array(pipe, r), // stdin
1 = array(pipe, w), // stdout
2 = array(pipe, w) // stderr
);
$pipes=array();
// We make a simple callback function with an ugly global var
function stream_callback(){
global $pipes;
$stdout_child=stream_get_contents($pipes[1]);
print(Callback received:\n);
print($stdout_child.\n);
}
$context=stream_context_create(array());
stream_context_set_params($context,array('notification' = 'stream_callback'));
$handle=proc_open(/bin/ls /tmp,$descriptorspec,$pipes,null,null,array('context'
= $context));
stream_context_set_params($pipes[1],array('notification' = 'stream_callback'));
while (true){
print(Waiting...\n);
sleep(5);

On most pages you probably won't notice much difference, but I have seen instances where the difference was painfully obvious. Andrew Yes and if your script takes .0002 seconds to run using double quotes it will only take .00019 seconds with single (depending upon how many quotes you have of course) :-) I'm coming in late to this thread so sorry if I missed this :) How much of a difference would it make if you have something like this: echo $foo bar bar bar bar $foo $foo; verses: echo $foo . bar bar bar bar . $foo $foo; ?In other words... You have a large application which is most likely to be faster? :) I would assume your 2 examples to be the same because the point is that the PHP interpreter must parse for vars to substitute when it encounters double-quotes whether there are any vars in it or not. With single-quotes the interpreter does not have to worry about it. Regardless, the speed diff is probably negligible, hence my flame inviting post. :-) ehh my answer is meant to be here: It's still wrong :) nope. it parses both, since you may have escaped characters within single quotes too. so the difference only comes in when you actually have a variable in the string. sorry its morning ;) Aaah, that's why you're confused :P yeah maybe. you're right, the bytecode is the same. but somewhere I heard that the parsing is the same too - because escaped characters can be in any string, though I'm not that sure about this anymore, as my link proved something else ;) greets Zoltán Németh ;) Cheers, Rob. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Off the top of my head:

foreach ($newDataArray as $k = $v) {
if (!empty($v['type']) AND $v['type'] != 'da') {
unset($newDataArray[$k]);
}
}
?
Optionally, you could use array_values() to re-index $newDataArray if
you need to.

Consider HEREDOC syntax. I'm not sure why you're doing your
tables like that, but I'm sure you have your reasons. Also, I'm
certain that hardcoding the image names like that is just for example,
since it would be much easier to use an array or something similar (if
it's not coming from a database or otherwise dynamically-generated).
?php
$myimage1 = image1.png;
$myimage2 = image2.png;
$myimage3 = image3.png;
$body .=EOT

tdimg src=$myimage1/td

/tr
tr
tdimg src=$myimage3/td
/tr

tdnbsp;/td
/tr

EOT; // This has to be at position one on the line, no matter what.

And, for good measure, the array way:
?php
$images = array('image1.png','image2.png','image3.png');
echo table\n;
foreach($images as $p = $v) {
$body .=EOT
tr
tdimg src=$v/td

Ross First, you need to change the date on your mail server, since it is reporting the year to be 2011, which in most cases and most servers I run automagically sets you as a spammer and reports the email and domain to the authorities and blacklists you. Secondly, if you want to use a variable, you need to make sure you are doing the $image1.jpg inside the body, because according to the snippet of code you have done, the $ is missing.

Single quoted strings do support some escape characters. As far as I
know only you can only escape a single quote and a backslash when
creating a string via single quotes.
yes, but I think the parser would still need to tokenize the string and
verify each token whether it contains an escape character or not - which
should be the same process as tokenizing and checking for escape
character and $ signs.
Nope, when processing a single quoted string there should be 4 available
parse branches:
EOF
'(end of string)
\
EOF
\
'
anything else
anything else
Whereas with a double quoted string you have something along the lines
of:
EOF
(end of string)
$(begin variable)
{(possible begin interpolation)
$(begin interpolation)
\
EOF
\
'
t
n
r
x
v
f
digit
anything else
anything else
So presuming no variable is embeded and assuming no escaped
characters... double quotes still need to check for the beginning of
variable interpolation which has 2 different start possibilities. With
respect to creating the byte code single quotes have 4 branches, double
quotes have 6 branches in the simplest of cases with no escape and no
interpolation. So one would expect compile time for double quotes to be
approximately 33% slower than for single quotes. Once compiled though,
the point is moot especially since most sites use a bytecode cache like
eAccelerator or APC. Even without a cache htough, the time difference is
tncy, and this is just for informational purposes :) There are
usually bigger eggs to fry when optimizing. One last thing though...
even if this were escaped and even if there were fifty variables
embedded, a good bytecode optimizer (not quite the same as a bytecode
cacher) would optimize the bytecode for caching so that the string is
broken up according to what needs to be interpolated and what does not.

It is a bit odd as it should delete it fine. Does using the PHP internal
function unlink() work better than shelling out? system() will possibly
have more overheads and it may require that the user has a valid SHELL
etc. too...

Hi everyone :) Happy friday to all of you!
Here's my issues, I am attempting to echo the results of mysqli query
out to my script just so I can make sure it's working right, what I'm
hoping to do in the long run is compare what was typed in a text box
to this info... It's for verifying a old password before changing to a
new password... So here is my query:
$oldpasswordquery = SELECT loginPassword, Record FROM current WHERE
loginPassword='{$oldPassHash}' AND Record='{$Record}';
$chpwold[] = mysqli_query($chpwpostlink, $oldpasswordquery) or
die(Sorry read failed: . mysqli_error($chpwpostlink));
$chpwresult = $chpwold[0];
$chpwrow[] = mysqli_fetch_assoc($chpwresult) or die('Sorry it didn\'t
work' .mysqli_error($chpwpostlink));
echo $chpwrow['loginPassword'];
print_r($chpwrow);
The echo and the print_r are for debugging and obviously wont' be in
the final script... Here is the error that I am getting:
[Fri Mar 28 12:14:39 2008] [error] PHP Notice: Undefined index:
loginPassword in /Volumes/RAIDer/webserver/Documents/dev/OLDBv2/admin/
chpwpost.php on line 18
Line 18 is where the echo is...
the print_r though shows this:
Array ( [0] = Array ( [loginPassword] =
42205baa2581d3fcd8d8f9c6b9746a1f [Record] = 2 ) )
So why can't I access it via $chpwrow['loginPassword']? I'm
stumped Anyone that can help me has a free beer waiting for them
the next time they are in my town! :)

Why would you pump that into an array instead of just calling it
result itself? I'd say you're just making it harder on yourself for
no apparent reason.
The problem seems to be on your other line.
$chpwrow[] = mysqli_fetch_assoc($chpwresult) or die('Sorry it didn\'t

Just fetch the row into a single variable and not an array. In your
example you'd need to access chpwrow[0]['loginPassword'] assuming it
was an empty array up to that point.
Calling things old query and old password isn't really adding any
value to your code. If you're only going to use it once then throw it
away call it result so it is easier to read and understand. But then
again feel free to ignore this. Also is there a reason why you aren't
using prepared statements?

That's because your loginpassWord is in another array.

[PHP] PHP code to write excel spreadsheet with multiple workbooks
Hi all, I have a linux based web app which prints an html screen of results. My users really want Excel spreadsheets with the same results. There is a PEAR application which does this, but from the PEAR description it seems to be pretty buggy (65 open bugs, average days open 616 days) and dated. My spreadsheets will be somewhat simple. They will have multiple workbooks and could be as large as 1 rows spread out over 100 workbooks (Bigger than the code can handle, according to one of the open bug reports). No colors, no formulas, no hyperlinks. I've checked the archives and found an example which shows me how to write the results of an SQL (MySQL, I am using postresql, but the example will still work) into a very simple Excel spreadsheet with just one table of results. Is there a way to get a php program to generate a spreadsheet with multiple workbooks?

It isn't just about sql injection, it's also about not letting your
application break because of user input. Getting errors because
someone puts an apostrophe in the form is bad. If I were using your
site and I saw my search term break a page I'd leave because there are
thousands of other sites that can get it right.

Let's explain this a bit
$chpwrow[] = mysqli_fetch_assoc($chpwresult) //
The response from mysqli_fetch_assoc() will be an array already.
You're then adding this into the $chpwrow[] array, which creates a
nested array. So to call it from your example, you'd need
$chpwrow[0]['loginPassword'].

No, but you can use http://php.net/array_map to do the trim before

[PHP] Re: character encoding
Hello, on 03/28/2008 12:08 PM Bill said the following: Hi Manuel In the body that column shows Brébeuf in Windows Outlook. You may want to try this MIME message composing and sending class that http://www.phpclasses.org/mimemessage Looks great Manuel.but my server is under dyndns and the DN isn't qualified so no mail functions available. I am not sure what you mean. This class can compose messages which can be delivered by different drivers, like the mail() function, SMTP client, qmail, sendmail, etc. If you can't use the mail function, you can still send message relaying them through an SMTP server, like for instance Gmail's. I was asking how to have the right character set translation so the data stored in the table show no grimmerish in the outlook window. A simple mailto link in the page with some basic content defined does the trick but the data retrieved from the table can look awsome in the mail client before the user sends it back to the owner email address. I'm making a site for myself. I'm a paintbrush artist, among other things, and I've set a buying level for the visitors. But one can ask to raise his level so he can buy more things in one session. For that I use a mailto link sent to my hotmail with the request giving the name and address of the sender. And that's where I can't control anything. The guy may have written accented caracters in his record and when that info is brought back, it messes the Outlook msg window of the sender. Can I force Outlook msg composer to use my Mysql table collation ? You can build mailto: links with a default subject and text, but I am not sure you can force Outlook to use specific HTML.

I basically would call this function lets say like:
munge( $url );
end in the end be returned the munged url, however, I don't
understand the
values you have like the readfile with that url -vs- failure?
I didn't munge... I provided code for a script that sends the
requested
image if it was requested with the appropriate key (presumably set
wherever the image was linked). If the key doesn't validate then
another
image is presented. It can say bugger off, it can say not found,
it
can say whatever you please. By placing the images outside the web
root
and using a script like this you are virtually guaranteed the visitor
can't just request images by making a lucky guess.
Let's say the above script was called: getUserImage.php
Then you might have the following in your HTML:
img
src=getUserImage.php?id=123amp;key=4fad1fea72565105d84cb187d1a3ed3bfb9

/
I understand what is happening here, however I really want something
simple like:
$link =http://www.whataver.com/whateverpath/;;
$image = 123456;
new_image = munge($image);
new_link = $link . $new_image;
or maybe
new_link = munge($link . $image);
Which would encode the whole link.
Either way this is what would go into the email message we send out.

Either way this is what would go into the email message we send out. Encode in what way? What are you actually trying to stop people doing? If all you're wanting to do is make sure people can't write a script that simply requests n.jpg over and over again with an incrementing n then all you need to do is obfuscate the filename when you store it on your server. You then store that filename in the database alongside the data it relates to. $filename = sha1(time()).'.jpg'; Obviously that's just an example. You can generate the filename in any way you choose as long as you check for duplicates before using it. If that's not the reason please explain exactly what you're trying to achieve rather than how you want to achieve it. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi!
I have absolutely no clue if this will work. This has been typed
directly into my mail client, so no guarantees.
?php
function toRGB($color) {
return array('r' = ($color 16) 0xFF, 'g' = ($color 8)
0xFF, 'b' = $color 0xFF);
}
This function returns an array of red, green, and blue from an integer
like 0xFF.
function toColor($r, $g, $b) {
return $r * $g * $b;
}
This function is basically the opposite of the above. (the integer
value from red, green, and blue)
$image = 'smiley.png';
list($w, $h) = getimagesize($image);
$im = imagecreatefrompng($image);
for ($y = 0; $y $h; $y++) {
for ($x = 0; $x $w; $x++) {
Loop through the pixels.
extract(toRGB(imagecolorat($im, $x, $y)));
Take the values from the array return of toRGB so we can use $r, $g,
and $b instead of $array['r'], etc.
if ($r = 0xCC $g = 0xCC $b = 0x33)
After some trial and error (looking at color charts), any red CC,
green CC, and blue 33 is some shade of yellow.
imagesetpixel($im, $x, $y, toColor(($r + $g) / 2, 0, $b));
The expression inside toColor() is my attempt to calculate the correct
shade of red from the shade of yellow.
}
}
header('Content-type: image/png');
imagepng($im);
?
:)
I don't understand half of that, can you explain what you did? (it
works) I was more trying to fix my problem then recoding the whole
thing though.
I hope that helps.

Okay I created a script that changes a basic smiley face into a

Hi!
I have absolutely no clue if this will work. This has been typed
directly into my mail client, so no guarantees.
?php
function toRGB($color) {
return array('r' = ($color 16) 0xFF, 'g' = ($color 8)
0xFF, 'b' = $color 0xFF);
}
This function returns an array of red, green, and blue from an
integer like 0xFF.
function toColor($r, $g, $b) {
return $r * $g * $b;
}
This function is basically the opposite of the above. (the integer
value from red, green, and blue)
$image = 'smiley.png';
list($w, $h) = getimagesize($image);
$im = imagecreatefrompng($image);
for ($y = 0; $y $h; $y++) {
for ($x = 0; $x $w; $x++) {
Loop through the pixels.
extract(toRGB(imagecolorat($im, $x, $y)));
Take the values from the array return of toRGB so we can use $r,
$g, and $b instead of $array['r'], etc.
if ($r = 0xCC $g = 0xCC $b = 0x33)
After some trial and error (looking at color charts), any red CC,
green CC, and blue 33 is some shade of yellow.
imagesetpixel($im, $x, $y, toColor(($r + $g) / 2, 0, $b));
The expression inside toColor() is my attempt to calculate the
correct shade of red from the shade of yellow.
}
}
header('Content-type: image/png');
imagepng($im);
?
:)
I don't understand half of that, can you explain what you did? (it
works) I was more trying to fix my problem then recoding the
whole thing though.
I hope that helps.
The thing is, it returns black. not red.
Oh. Replace the toColor function with the imagecolorallocate function
and add $im as the first parameter.
