Or, for that matter, load the images in through http://php.net/gd and And the potential irony is that: in order to protect against executables masquerading as image files you trigger a zero-day exploit of gd :) I would love to hear Chris Shiflett's views on this.

[PHP] Copy of image - smaller
Hi there!
When I upload a picture from a form, then I want to create a copy with a
smaller image.
For example: I upload a picture with dimensions 200x150 name 4.jpg. I also
want a copy of this image but with the dimensions 100x75 pixels. I've tried
this below, but I'm missing something I think... :-)
I'm using PHP 4.x (don't know exactly the vers.nr, but I can search for it
if it is of importance)
The code down below is a function for uploading a picture. The part I want
help with is after the comment: //What should/could I do here?
Best regards
Gustav Wiberg
?php
function uploadPic($idUpload, $picUpload, $addUpload, $copyFile, $toPath) {
//Upload chosen file to upload-map (
//
if (strlen($_FILES[$picUpload]['name'])0)
{
//ECHO yes! ID=$idUpload PIC=$picUpload ADD=$addUploadbr;
$uploaddir = dirname($_FILES[$picUpload]['tmp_name']) . /;
//Replace .jpeg to .jpg
//
$_FILES[$picUpload]['name'] =
str_replace(.jpeg,.jpg,$_FILES[$picUpload]['name']);
//Get first 4 last characters of uploaded filename
//
$ble = strtolower(substr($_FILES[$picUpload]['name'], -4, 4));
//Move to path $toPath (followed by what to add after file (that is sent
to this function)) and ext.)
//
$mfileAdd = $idUpload . $addUpload . $ble;
move_uploaded_file($_FILES[$picUpload]['tmp_name'], $toPath . $mfileAdd);
//echo mfileAdd=$mfileAddbrbr;
//Set appropiate rights for file
//
//echo FILE TO TEST=$mfileAdd;
chmod($toPath . $mfileAdd, intval('0755', 8));
//Copy this file to another file?
//
if (strlen($copyFile)0) {
$mfile = $idUpload . $copyFile . $ble;
//echo MFILE=$mfile;
copy($toPath . $mfileAdd, $toPath . $mfile);
chmod($toPath . $mfile, intval('0755', 8));
}
//What should/could I do here?
//
//Set new width and height
//
$new_width = 100;
$new_height = 200;
$tmp_image=imagecreatefromjpeg($toPath . $mfileAdd);
$width = imagesx($tmp_image);
$height = imagesy($tmp_image);
$new_image = imagecreatetruecolor($new_width,$new_height);

[PHP] Perl PHP output format mismatching
Hello,
I'm currently writing a PHP page, which uses a small Perl script. But I
encounter an annoying problem with endline character.
A small example :
$perl = new Perl();
$perl-eval('print toto\ntata');
In this configuration, the HTML page generated sends me :
toto tata
Of course and you should have understood already :-), I would like :
toto
tata
I suppose I have to do a little manipulation on the PHP streams to make them
correctly interpret the endline character returned by Perl. But I didn't find
what :(
Help would be greatly appreciated.
Thanks.

\n is not html so your browser doesn't know you want a newline. What
you need is a br tag.

[PHP] Check before uploading
Hi there! Just a thought. Someone posted a question if you could check filesize before uploading some days ago. Maybe this is possible with Javascript? Javascript wouldn't be the best solution, cause of it's incompability between browsers, that users can inactivate it. But it's might be better than nothing..

I don't think the author does not know how to handle multidimensional
arrays. I thought the author was more concerned about performance than
other issues people like as coding beautifuly... Maybe author's
approach is weird, but its twice faster in the worst case!!
Sure the author only needs to loop the whole array and doesn't need
multi-dimensional approach... 'cause its a lot faster to iterate once
the array is filled!!
Look at the test I've done (below) its seems filling multi-dimensional
arrays is n/2 faster than single dimension, but then when you need to
read the array data, a multi-dimensional approach is always worse than
n*6!!
Your setup is odd. I get much more similar results with both php 4 and 5.
You're also using a more than slightly odd way of iterating through the array.
These does exactly the same as your Test functions and are considerably faster:
?php
function Test_c() {
global $testC;
for ($a=1;$a999;++$a) {
for ($b=1;$b999;++$b) {
$testC[$a][$b] = $a . $b;
}
}
}
function Test_c2() {
global $testC;
foreach ($testC as $k = $v) {
foreach ($v as $k2 = $v2);
}
}
?

Fill style A, bidimensional array: 3.0747

You can buffer the file to the client via fread or such and buffer only a few chunks and let php wait till he downloaded it. On sucessfull download you might add a db entry or whatever.

I don't think the author does not know how to handle multidimensional

other issues people like as coding beautifuly... Maybe author's
approach is weird, but its twice faster in the worst case!!
Sure the author only needs to loop the whole array and doesn't need
multi-dimensional approach... 'cause its a lot faster to iterate once
the array is filled!!
Look at the test I've done (below) its seems filling multi-dimensional
arrays is n/2 faster than single dimension, but then when you need to
read the array data, a multi-dimensional approach is always worse than
n*6!!
Your setup is odd. I get much more similar results with both php 4 and 5.
You're also using a more than slightly odd way of iterating through
the array.
These does exactly the same as your Test functions and are
considerably faster:
?php
function Test_c() {
global $testC;
for ($a=1;$a999;++$a) {
for ($b=1;$b999;++$b) {
$testC[$a][$b] = $a . $b;
}
}
}
function Test_c2() {
global $testC;
foreach ($testC as $k = $v) {
foreach ($v as $k2 = $v2);
}
}
?

Hi Robin,
Don't thought my setup is odd. Only I can say my computer maybe isn't as
faster than yours. I use centrino mobile, windows xp, and test was run
on php 4.3.9 ( sorry i missed that, thought was 4.3.4)
I know it can be coded to be faster, but my point with that php snippet
was to compare the same odd way with single or multi dimensional
approaches. Sure $a.$b is faster than $a$b and foreach than do while
(the more if you didn't use each element datum!! that's hi -
optimization! does sense for you using foreach without assigning any
value from it? yes, you've got them inside foreach $v2 - $k2, but in my
code i've got too them inside key($v) $v[key($v)], and I do assign them
to another var, so if you want to compare performance, please to it too!
anyway I checked this and both multidimensional approaches performs
pretty equal. )
I didn't code that snippet to the best / faster execution methodology
for this individual case but a generic odd way for comparing both
cases. The same I did in python, as that language as far more adaptable
data structures for letting you choose the best for your case needs (I
could use python numarray (uses C arrays) and I thought you could't beat
it in PHP or any PHP C extension, but that's far from the purpose of my
posts.
If do I use $a.$b instead $a$b and assign each element key val from
foreach in type c test, that's what I got: -see below- B C perform
nearly equal on total time, of course, the best approach would be highly
dependent on the real data to use. The only I thing could say about your
foreach approach is I allways avoided using it in some kind of projects,
as it does a copy of the data on every iteration, so when using lots of
objects, huge data, or pass-per-reference had lot of memory performance
issues using it in php4 -Im speaking about very long-running scripts
where these issues really care- so do { } while(next()) is the only you
can use safely...
Notice huge gap in running the type A test in my computer and in yours
for php 4.4.0 - me 4.3.9, you get 5.59 and I got 13.9, and other tests
seems my install always performs better than yours! :-) (type b: you
5.12 - 2.40 = 7.54 me 4.08 - 1.66 = 5.57 that's about 2 secods!!). That
means to me so this test don't probe nothing, they are all very
variable... I don't know why that great difference, but I don't think
the php revision changes from 4.3.9 to 4.4.0 are relevant enought as for
these performance gaps. We should use a real tests library for choosing
best case of several runs, and so on...
Anyway these are the results using your test_c modified code with two
lines added... notice filling type A and C share the same code, and
there is some gap: 1,97 - 2,16 !

Re: [PHP] Security Concerns with Uploaded Images:
To summarise: the uploading of an executable masquerading as an image file can be protected against via coding at the application level My thought is that it wouldnt be too hard to have some kind of script masquerade as a gif file, and perhaps cause damage. More worrying and much harder to protect against are zero-day exploits against the graphics libraries themselves - libpng, libtiff, gd lib, zlib - have all had security problems in the past. Or, for that matter, load the images in through http://php.net/gd and And the potential irony is that: in order to protect against executables masquerading as image files you trigger a zero-day exploit of gd :) I would love to hear Chris Shiflett's views on this. I certainly don't speak for Chris, but I can say that I've read his book Essential PHP Security and didn't find mention of any concerns regarding executable code masquerading as an image file. He does speak about attaching stuff to a url request for an image to make a CSRF (cross site request forgery), but the offending code was not in the image. However, if this is a real concern, then what about: 1. Uploading the file into a black hole as Wolf provided some time back. I think he tackled a similar problem. 2. Resampling the image -- I doubt any code that's been resampled can pose any threat. In fact, there are several things one can do to an image that would alter the internal binary significantly while not adversely affecting the image much. Alter any of my programs by a single character, and they will crater -- of course they seldom need help to do that. tedd -- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Development Environments/Automation
Hello, I am being asked to find some sort of development environment for PHP/MySQL, if is exists, in which it has some sort of automation/wizzardry. What is being done is a mass of MSAccess interfaces, forms, reports, etc. are needing to be re-written in php and connected to a MySQL database instead of the Access. What is being asked for is something that although being able to build some interfaces through wizzards/gui's, that is be somewhat logical, and streamlined in its management of code and html. Something that implements some kind of smarty tag or similar woould be good instead of say... Macromedia which can do some fairly bloated and cumbersome things with logic and markup. Also, It would need to be flexible enough to manage projects back and forth between wizzards, and hand coding so that one wasn't limited to the narrow applications of the wizzard. Does something like this exist? I have played around with Macromedia, and another app called CodeCharge Studio. I hope that I am asking the right or at least an intelligent question. -Brian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Sessions - session_start()
session_start() doesn't need to be the first line of your PHP code, it just needs to be called before any other output is performed. Including any blank spaces or anything else. If you have: --- 1: 2: ?php 3: session_start(); 4: ? --- It's not going to work because you have a blank line being output to the browser for interpretation. Same problem would occur if you even had: --- 1: ?php // Leading single blank space character 2: session_start(); 3: ? --- Output buffering may help in some cases, but I'd look at the error where it says: output started at /var/www/html/index.php:9 Sounds like there's a way to solve this without resorting to output buffering. In addition to the basic command reference listed below, check out the user contributed comments on these pages: http://www.php.net/manual/en/function.session-start.php http://www.php.net/manual/en/function.ob-start.php According to the first comment, ob_end_flush() is called automatically at the end of your script, so it's not mandatory that you use it (but probably good 'complete' programming practice).

$root = $doc-getElementsByTagName('a')-item(0);
$root-setAttribute('b', 'gt;');
$root-setAttribute('b', '');
// This will never be executed
echo done\n;
--
That another setAttribute() -call never finishes, and the script will
just eventually die because of PHP Fatal error: Maximum execution
time.. I have tried this with cgi and cli versions of PHP 5.1.4, 5.1.1
and 5.0.5 on different servers (and different ISPs).
When running, php-process takes all CPU. I tried to debug it with gdb
and got this backtrace: http://www.palomaki.fi/dev/tmp/bt.txt - I ran
it, waited for ~5 seconds, and hit ctrl+c to pause the program to get
the backtrace. node_list_unlink seems to be calling itself forever.

You need more like: somepage.php htmlbodyimg src=image.php /This is text output./body/html image.php ?php $image = imagecreatetruecolor(400, 300); header(Content-type: image/png); imagepng($image); ? So you need SEPARATE URLs and files for the HTML and the PNG -- exactly the same as you would with static HTML and PNGs. Or any image format, not just PNG. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] cURLing sites for images

OK, I give up (for now at least). I've been trying to figure out a
way
to run a single script and download my favorite comics. The problem
is
that:
1. The URLs include numerous websites (and the image is hosted on
another server from the original)
2. The filename can change but has the same basic name
What I would love to do is use cURL to load the list of URLs, and then
save all the images within each page into a directory based off the
date. What I have not been able to figure out how to do is use CURL
to
open the page and save all the *.gif and *.jpg files only.
A preg to find the .gif and .jpg files, and then you need to use
CURLOPT_BINARYTRANSFER to get the .gif/.jpeg
If you switch back and forth to text/binary, you'll want to get PHP
from CVS, cuz there was a bug:
http://bugs.php.net/bug.php?id=37061
Thank [deity] the PHP Devs could take my meandering ill-formed bug
report and turn it into something useful... :-^
Anyone have a good pointer on this? I've been going through the
archives and some tutorials, but most seem for posting to another
site,
not snagging files.
It should look something like this:
?php
$cookie_file = '/path/to/php/writable/file/somwhere/cookies.txt';
//basic curl handle:
$curl = curl_init();
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie_file);
//snag HTML
curl_setopt($curl, CURLOPT_URL, 'http://example.com');
$html = curl_exec($curl);
//Find the images:
//This pattern is almost for sure wrong cuz I suck at PCRE:
preg_match_all('/img[^]+src=([^]+)/iS', $html, $images);
$images = $images[1];
//snag each image in turn:
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
foreach($images as $image_url){
curl_setopt($curl, CURLOPT_URL, $image_url);
$image = curl_exec($curl);
file_put_contents(/some/path/to/where/you/want/images/$image_url,
$image);
}
?
This is untested code off the top of my head, but it should be pretty
close.
You could maybe use Tidy or something DOM-like to find the images in
the URL if you were more of a purist, but I'm assuming that isn't the
issue, based on your post.

);

Hi there!
When I upload a picture from a form, then I want to create a copy

smaller image.
For example: I upload a picture with dimensions 200x150 name

also want a copy of this image but with the dimensions 100x75
pixels.
I've tried this below, but I'm missing something I think... :-)
I'm using PHP 4.x (don't know exactly the vers.nr, but I can
search for
it if it is of importance)
First of all *run* to this thread and add some security checks to
your
image uploading:

Secondly, what does or doesn't happen with your code?
It looks fine at first glance but do you get an error? What do you
expect it to do and what does it actually do?

At least, that was my assumption when I played around with this way back when. After I asked my webhost to increase the size, it got taken care of, and I never checked again... Preferably by using php, but if not is there another web tech (e.g. Java applets) that will allow me to do this?

Re: [PHP] Class/function scope general question
You can't do that.
The whold class has to be in a single contiguous file.
Last I checked.
On the plus side, it's incredibly unlikely that having the functions
in separate files was a Good Idea...
On Fri, May 12, 2006 12:34 pm, Edward Vermillion wrote:
I'm doing some re-writing of a huge class I've got (don't think OOP
cause it's really not, just the usual class full of functions). What
I'm doing is moving the functions out of the class and into separate
files so the (I'm hoping) memory footprint will be smaller.
The basic setup I started with is:
class foo {
function doSomething()
{
switch($var) {
case '1':
$this-bar();
break;
case '2':
$this-baz();
break;
}
}
function bar(){ // do something useful }
function baz(){ // do something else useful }
[...]
}
I've moved bar() and baz() into their own file and am now including
those files from the original functions as so:
class foo {
function doSomething()
{
switch($var) {
case '1':
$this-bar();
break;
case '2':
$this-baz();
break;
}
}
function bar(){ include_once 'bar.php'; newBar(); }
function baz(){ include_once 'baz.php'; newBaz(); }
[...]
}
where newBar() and newBaz() are just the functions copied from the
original class like
bar.php
?php
function newBar(){ // do something useful }
Now the interesting bit I don't quite comprehend...
var_dump($this); from inside newBar() returns null.
Sort of unexpected behavior to me, but only slightly. Shouldn't the
newBar() function pick up the scope from foo::bar() since, as I
understand includes, it's the same as writing the code in the file
where the include statement is at?
Outside of newBar() in bar.php var_dump($this) gives me the foo class.
Is it because there is basically a function within a function at this
point and somehow the scope of $this is being lost? I would have
thought that it would carry down, but obviously I'm wrong.
Not looking for a fix really, I'm passing in a reference to $this to
newBar() so it's all cool there, just looking for an explanation to
have for future reference.
PHP4.4.2 btw... if that makes any difference.
Thanks!

[PHP] Trouble sending data via TCP socket
To further my understanding of how Jabber works I have decided I should try and write my own XMPP implementation in PHP. However, I've run into trouble rather quickly. To connect to a Jabber server, one must open a TCP socket to the server (typically through port 5269) send an XML-based stream header, wait for the server's confirmation and then log in, etc. As an initial test I tried to open a TCP socket, send a stream header, get the server's response, then disconnect. I did so thusly: $server = jabber.org; //example server $port = 5269; //default port $nsStream = http://etherx.jabber.org/streams;; // Streams namespace $socket = stream_socket_client(tcp://$server:$port); $header = stream:stream to='$server' xmlns='jabber:client' xmlns:stream='$nsClient' xml:lang='en' version='1.0'; fwrite($socket, $header); //send header echo stream_get_contents($socket); //get server confirmation //close connection fwrite($socket, /stream:stream); fclose($socket); I'm supposed to get something like this in reply (taken from my desktop Jabber client's debug window): ?xml version='1.0'? stream:stream xmlns:stream='http://etherx.jabber.org/streams' id='4468F937' xmlns='jabber:client' from='jabber.org' Instead, I get this error message: stream:error invalid-namespace xmlns='urn:ietf:params:xml:ns:xmpp-streams'/ /stream:error That I get a conformant Jabber error message suggests that I -am- at least connecting to the server properly, but that the data is not getting to the server intact. I am certain that the XML header is correct: I also tested another PHP Jabber implementation[1] with the same result, even though a search of this mailing list suggests that said implementation has been known to work for other people. Since I tested it on two different machines (my home Windows computer and a Linux Dreamhost Web server) using three different versions of PHP (PHP 5.1.4 Winodws CLI, PHP 4.3.3 Windows CLI, PHP 5.1.1 Linux FastCGI), it's pretty clear that it's not a bug in the version of PHP I initially tested on. I also tried connecting to three different Jabber servers (my private dark-phantasy server, jabber.org, and a test Wildfire server on my colleague's machine) and all three gave me similar errors (with differing levels of spec compliance...). In short, I am stumped. If anyone with some experience in these matters could shed some light on my problem I would be most grateful. [1] http://cjphp.netflint.net/ -- J.

No, you cannot display both a webpage and send a file on the same page to the user. What you could do is save the processed file in a temporary folder and provide a link to download the file in your processing statistics page. Or, you could redirect the user to the file after showing the statistics page. Rabin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
