[PHP] Intermittent Seg Fault with PHP4.3.8 + FTP
I'm using PHP to write some backup scripts. One of the scripts uses PHP to connect via FTP to a server, download some scripts and tar them up. I'm getting intermittent segmentation faults with this script, and I'm not sure what to report to troubleshoot this. Can someone tell me what would be useful information to help determine the case of this seg fault? Thanks. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

> 1) Environment > a) OS > b) PHP Version > c) CLI or web-based > d) Are you running php as an apache module? I'm runnning PHP 4.3.8 in CLI on Redhat 9 in this particular case. PHP compiled with --enable-ftp (among other things). PHP is installed as an Apache2 module, but (obviously since this is CLI), Apache isn't involved here. All other scripts work fine (CLI and web-based). Server is a dual MP 1600+. I've got the same setup running on a non-SMP server and it also seg faults at about the same place. > 2) Logs/errors > a) example from log file (just the error line(s)) > b) what is segfaulting?

Nothing in the sys logs. The script runs for a while (I've got it echoing what file it is d/l'ing), but then displays "Segmentation Fault" after it downloads several files. > 3) Any other pertinent information It does not die after a specific file, e.g. it dies randomly. Also, if I reduce the number of files to be d/l'ed, it won't seg fault. Usually it faults after d/ling about 210 files (it varies), but I've seen it go as high as 290. Its actually made it all the way through the script once today, but seg faults most of them time. The random nature leads me to believe that this is some sort of harmful interaction between this server and the FTP server. The FTP server is a Windows-based host. An almost identical script runs just fine while connecting to other servers. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] mysql_connect does not connect
OK, I'm going to jump in and try and take a stab at this. Sam, if you wouldn't mind answering a question: are you still unable to connect to your mysql server? I'll also add that your understanding of firwalls is lacking. Regardless of where your server is (local or remote), there is still a client-server relationship happening. If you are trying to connect to localhost/127.0.0.1 (use the latter as previously recommended), your system is acting as the server. ANY consumer firewall (free or otherwise) is going to block incoming packets not related to an already established connection, regardless of where they originate. Lots of consumer firewalls are going filter traffic on localhost because lots of vicious spyware out there are starting to install "daemons" on systems then rewiriting the HOSTS files to pull ads from the localhost rather then hitting the marketers servers. If you don't believe me, google for "spyware HOSTS file". To assume that your firewall (ZoneAlarm, XP, or otherwise) is not in play here is false. At this point, you need to disable the firewall completely (just for testing) and/or find a way to open the MySQL port (port 3306) on localhost to incoming traffic in your firewall. I know that you don't think this is the problem, but the only way you are going to know is if you try. I'm sorry that you feel its a time-consuming process. I'm sorry that you are confused about the involvement of the firewall. I'm sorry that you feel you know better than everyone on this list. Just try this and prove us wrong.

Your conditional will never evaluate to true. What is $RESULT? Where
did it come from? $RESULT is not a built-in PHP variable or function,
so empty($RESULT) will always be true, making !empty(...) always
false.
Also, it should be noted that if a form field exists, it will exist in
the form data POSTed to PHP, even if the field is empty.
I'm guessing that what you want to do is something like this:
if(!empty($_POST['firstname']) {
$name = $_POST['firstname'];
} else {
$name = 'Sir or Madam';
}
empty() will evaluate to false if the field is empty OR if the field
does not exist. Also not the use of $_POST instead of $_REQUEST.
This will ensure that your data is actually coming from the form
instead of an attacker trying to inject data with $_GET variables or
some other source.

[PHP] Reading files in PHP 5.3.0
I've been beating my head against a wall all day and can't figure this
one out. The code below worked perfectly in PHP5.2.4. However, I
recently upgraded to PHP5.3.0 and this code no longer works.
The function below accepts the path to a text file containing headers
from a cUrl session (example attached). Basically this function opens
to log file, looks for certain headers and captures some information
from that line. When called on the attached file (or any log file for
that matter), the following is output:
array(2) {
["ResponseCode"]=>
NULL
["ErrorMessage"]=>
NULL
}
Which means that nothing is getting read from the file.
Now, I'm going to qualify all of this by saying I'm running OSX Snow
Leopard, so I'm fully prepared to believe that Apple fucked something
up in it, as they have done to third party packages on other occasions
in the past. Well... to be fair, they don't usually fuck up third
party packages, rather they introduce "enhancements" to the OS that
prevents certain packages from working correctly and could care less
that they broke it.
So did anything change in PHP5.3.0 that would preclude the code below
from working? Am I going crazy? Or did Apple f...@# something up in
this release?
Thanks,
Steve

Nothing, not even an empty variable. Which is why I think something
is completely screwed up here.
BTW, squares at the end of lines are your platform not interpreting
EOL characters correctly from another platform. Generally, its the
sending client thats not being friendly, not the receiving client.

You can generate reports and spit out HTML in a new window and have the user print the report from the browser, but that has many drawbacks. It only works with simple data sets, its difficult (or impossible) to control page breaks, lack of precision placing, etc. Now I use FPDF to generate PDF reports (http://www.fpdf.org/). Its free, easy to use, and pretty flexible. It allows you to do precision placement on a page, add headers, footers, etc, etc, etc. Be sure to check out the "Scripts" section, its got a bunch of useful tips for expanding functionality of the classes. There is another commerical product out there (can't thin of the name right now) that is supposed to be faster, but FPDF is pretty fast in our applications. I also use the JPGraph package for generating graphs (http://www.aditus.nu/jpgraph/). This is *really* slick. Its free for personal use, about $125 for commercial use. You need to install some additional PHP libraries (JPEG, PNG, GD at least), but its fast and easy. I love playing around with this product because the possibilities for what you can do are almost endless.

[PHP] PHP4 vs PHP5 Performance?
Recently, I've been doing a lot of benchmarking with Apache to compare different OSes and platforms. I did a stock install of Ubuntu 7.04 Server w/ Apache2 and PHP5. To do the test, I used ab to fetch the following document: PHP Web Server Test I ran ab in a loop 12 times with 10,000 connections and a concurrency of 10. Then I threw out the highest result and the lowest result and averaged the remaining values. Both PHP4 (v 4.4.7) and PHP5 (v 5.2.3) were built as Apache modules, and I simply changed Apache's config file to swap modules. The results were somewhat surprising to me: on average, PHP4 significantly outperformed PHP5. Over our LAN PHP5 handled roughly 1,200 requests / sec while PHP4 handled over 1,800 requests / sec. Since everything I have heard/read is that PHP5 is much faster than PHP4, I expected the opposite to be true, but the numbers are what they are. Also PHP on Apache1 was much faster than on Apache2. The only difference I can figure is that PHP5 was the packaged version that comes with Ubuntu and I had to compile PHP4 from source since there is no package for it in Feisty. But I wouldn't expect a 50% increase as a result of that. Any thoughts on this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Questions about overloading and visibility in PHP5
I've been doing a bunch of reading about objects and overloading in
PHP5, but I've got a couple of questions that I can't seem to find the
answer to online. Suppose the following code in PHP5.2.4:
$name to $val...\n";
$this->{$name} = $val;
}
public function __get ($name) {
return "The value of $name is {$this->{$name}}.\n";
}
}
?>
My questions are as follows:
1) It seems that the getter and setter are not called on every single
call. For example, if I do the following:
$bar = new foo;
$bar->x = 'x';
There is no output. I would expect to see "Setting $this->x to x."
Another example:
$bar = new foo;
$bar->y = 'y';
echo $bar->y;
I would expect this to see "The value of y is y." but instead I just
get 'y' as output. So when do the various setters/getters get used?
2) It seems that getters ignore the visibility of properties. Why is
this? For example:
$bar = new foo;
echo $bar->z;
I would expect this to throw an error about accessing a private
member, but it outputs "The value of z is z." just fine. If I remove
the __get() overloader, an error is thrown.
I'm guessing that the answer to all of my questions is some how
wrapped up in visibility and overloading. Unfortunately I cannot find
any resource that documents the interactions. TIA.

[PHP] String parsing issue in PHP 4.3.10?
I'm working on a script that will parse through a long string using
regexs to pattern match a certain format. I'm having an issue with a
'?>' in a string being picked up as an end-of-code character, but only
if the line before it is commented out. If the line before is NOT
commented out, PHP processes the file as normal (errors out, but I can
fix that). I'd appreciate it if someone else could run this script
and see what happens.
PHP Version:
$ php --version
PHP 4.3.10 (cli) (built: Dec 20 2004 10:45:58)

Unexpected results:
If line 16 (indicated below) is commented out, the '?>' in the string
on line 17 makes PHP stop parsing and the rest of the script is simply
dumped to stdout. If line 16 is NOT commented out, the '?>' is NOT
picked up as being a PHP tag and it parses the script as PHP.
Environment:

Consider that a 1-to-many relationship is much easier to deal with than a many-to-many relationship. What I mean is, if you are looking at the element "Round", don't concern yourself with "Fruit" or "Long". Figure out your "upstream" path for the current element, e.g. "Food:Vegetables" (which should be easy if you assume that each element only has 1 parent).

Not neccesarily; it depends on how big your tree structure is. If you only have 10 "categories" where an item could be placed, a list of all available "categories" might be an OK solution. However, if you have 100 "categories," listing all of them is impractical. Even if you only have 10 categories, you should plan for the day when you will have >10 categories.

Usually we know which category we want to place the item in before we begin to lay it up (if we don't, we can move an item at any time simply by changing the parent of the item). So in your case, if you wanted to create a new item in the category "Round", you would first have to navigate to Food > Vegetables > Round, then create the new item. This may seem more complicated, but think about how much time your users are going to spend scrolling through a list of lots of categories compared to this approach. > But I wouldn't be building the entire tree if I were only looking at a > specific node. That's the beauty of it! :) You don't need the entire tree if you are working on a specific node. Look at it this way: you can only work on one item at a time, right? If you are working on the item "Fruit," why do you care that the parent of "Long" is "Vegetables" or that "Round" has two children, "Spikey" and "Smooth"? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not neccesarily; it depends on how big your tree structure is. If you only have 10 "categories" where an item could be placed, a list of all available "categories" might be an OK solution.

This MySQL extension doesn't support full functionality of MySQL versions greater than 4.1.0. For that, use MySQLi. If you would like to install the mysql extension along with the mysqli extension you have to use the same client library to avoid any conflicts. === PHP4 doesn't support the mysqli extension, so you must compile PHP w/ --with-mysql=/your/mysql/prefix/dir -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
