RE: [PHP] 'Code Snippets' you couldn't live without
Another code snippet I use quite regularly builds a form select list from a
delimited string.
function displayFormSelect($selvals, $selname, $val=''){
$optval = explode(,, $selvals);
$retval = select name='$selname';
foreach ($optval as $key = $value){
$retval .= option value='.$value.';
if ($value == $val)
$retval .= selected;
$retval .= .$value./option;
}
$retval .= /select;
return $retval;
}
Basically, I use it like so:
$optstring = 'Option 1,Option 2,Option 3';
$optname = 'frmoptions';
$optsel = 'Option 3';
$formsel = displayFormSelect($optstring, $optname, $optse);
echo $formsel;
The optional third value defines the option that appears 'selected' if
provided.
Looking at it, it would be pretty easy to change this to pass a recordset
array to it etc.
Much warmth,

[PHP] Downloading Large (100M+) Files
Hi.
I have searched a few of the mailing lists, and have not found an answer.
I am working on a site that is currently running gforge (
http://gforge.org/ ). The process that is used to download files from the
file repository is something like:
Header('Content-disposition: filename='.str_replace('', '', $filename).'');
Header(Content-type: application/binary);
$length = filesize($sys_upload_dir.$group_name.'/'.$filename);
Header(Content-length: $length);
readfile($sys_upload_dir.$group_name.'/'.$filename);
The issue is that readfile writes it to the output buffer before sending it
to the client. When several people try to download large files at the same
time (The Ant Download Manager - trys downloading things by opening 20
connections). 20 x a single 250Meg file rips through physical and swap
pretty fast and crashes my machine.
Any thoughts on how to turn output buffering off? I have tried, but have
not been able to get it working properly.
On a similar note, is there a portable way to determine available system
memory (physical and swap)? Right now I am using something like:
=
# ensure there is enough free memory for the download
$free = shell_exec('free -b'); $i=0; while ( $i != strlen($free) ) {
$i = strlen($free);
$free = str_replace(' ',' ',$free);
}
$free = str_replace(\n,'',$free);
$freeArray = explode(' ',$free);
$total_free = $freeArray[9] + $freeArray[18];
==
Calling shell_exec isn't very portable to other systems.
Thanks in advance.

[PHP] Lost session variables still confounding me
I think I've tried just about everything that I found
googling. Still no luck. I'm throwing this out again,
with the chance that something missed before maybe
noticed.
Page 1:
//Start the Session - begin Block
@session_start();
form method=POST name=form1 action=Page2.php
input name=ListingName type=text id=ListingName
/
Page 2:
//Start the Session - begin Block
@session_start();
//Set the session variable, input on Page 1
$_SESSION['f1a'] = $_POST['ListingName'];
Page 3:
//ON this page, I check that f1a still exist using an
echo - generally it does unless :
//Start the Session - begin Block
@session_start();
if (count($myarray) 5) {
$_SESSION['arrayerr'] = you have selected too many
industries;
header (Location: Page2.php);
exit;
}
If the validation above passes, no problem. But if it
doesn't, once it redirects, the session variable , f1a
is bye bye.
I've tried passing the session_id, session_name, i've
printed out both to make sure they remain the same.
I' ve done relative and absolute paths.
Searching for this problem , it seems I'm not the only
one who has suffered with this issue. Some was prior
php 4.3 when session_write_close was needed. I've
thrown that in as well.
I just don't get it.

Page 1:

Is it necesarry to start the session here? Maybe it is if they have to
be logged in or something
Normally I only start the session when I indeed can assign some session
variables in the same page
Page 2:
//Start the Session - begin Block
@session_start();
//Set the session variable, input on Page 1
$_SESSION['f1a'] = $_POST['ListingName'];
//Set the session variable, input on Page 1
session_register('f1a');
$_SESSION['f1a'] = $_POST['ListingName'];
Page 3:
//ON this page, I check that f1a still exist using an
echo - generally it does unless :
//Start the Session - begin Block
@session_start();
if (count($myarray) 5) {
$_SESSION['arrayerr'] = you have selected too many industries;
header (Location: Page2.php); exit; } If the validation above passes,
no problem. But if it doesn't, once it redirects, the session variable
, f1a is bye bye.
Why do you put the error message in a session variable?
Also you will get an error (header already sent) I suppose since you
first send some text and then do a header.
Also if you rederict to page2.php, at the beginning of that page you set
$_SESSION('f1a')= $_POST['ListingName'];
Since there are no POST values (you are coming from page3)
$_SESSION('f1a') will get an empty value...
Maybe this causes the loss...
I dunno if this will help, I'm not that good at php.

If there is a POST value, it will be used, else $_SESSION['f1a'] will

Thinking that by sending the variable back to page 2
it would hold. The error variable takes.

This won't have any effect if you don't actually post the form to Page
3, again it's just resetting the session f1a value to null.
Try sticking this on Page 2 (ensure you have a session_start() at the
top of the page and that you replace the 'var' text below with the
correct ones.
if (isset($_POST['var']))
{
echo 'POST value found, setting the session var now';
$_SESSION['var'] = $_POST['var'];
}
else
{
echo 'No POST value found, dumping session contents';
print_r($_SESSION);
}
Run it - make it error - what does it end up saying?

Of course it does
Well, it's *a* possible fix -- depends on whether it meets your exact
requirements.
Just follow the data flow to see what's going on:
Page 1:
the value inserted by the user into form field ListingName is sent, when
the Submit button is clicked, to...
Page 2:
here you copy the value set by the user, and presented to you script in
$_POST['ListingName'], into $_SESSION['f1a']
Page 3:
if your validity test fails (count($myarray)5), then you redirect back
to...
Page 2:
here, once again, you attempt to copy $_POST['ListingValue'] into
$_SESSION['f1a'] -- but, because, this time, you haven't got here from the
form, $_POST will be *empty*, and so $_POST['ListingName'] will equate to
NULL (and this access will probably generate a NOTICE, which you would see
if you had full error_reporting turned on), so NULL gets assigned into
$_SESSION['f1a'], and hey presto! it's gone. (Incidentally, this access to
an undefined index of $_POST will probably generate a NOTICE, which you
would see if you had full error_reporting turned on.)
By testing $_POST['ListingName'] to see if it's isset(), you won't attempt
to assign the bogus NULL into $_SESSION['f1a'], and your problem goes away.
The only fly in the ointment with this is if your form can be submitted in
such a way that $_POST['ListingName'] can legitimately be !isset(). My
personal preference here is to set a flag in the session to say your
redirecting backwards on error, and then test it before attempting to grab
$_POST values (and clear it!). I'd also be very defensive about coding the
redirect, and always include a session_write_close() and the SID -- probably
in the majority of cases they're not necessary, but at least the code won't
fall over if it's ever used somewhere where they are needed. So I'd have
something like:
Page 2:
if (isset($_SESSION['_error_flag']):
unset $_SESSION['_error_flag'];
// if subsequent logic needs it, I might set a local error flag here
// other error actions
else:
// ok, should be processing a form submission
$_SESSION['f1a'] = $_POST['ListingName'];
// etc...
endif;
Page 3:
if (count($myarray) 5):
$_SESSION['arrayerr'] = you have selected too many industries;
session_write_close();
header (Location: Page2.php?.SID);
exit;
endif;
Hope this helps.
Cheers!

You seem to have a very hazy view of the flow of your data from one script
to the next. I really do recommend sitting down with a printout of your
code and a balnk sheet of paper and a pen, and manually working through as
if you were the PHP processor, and recording all the data flows and setting
and unsetting of variables. It can be a real eye-opener about where values
are going and being used, and can really help solidify your understanding of
the data flow both within scripts and from one script to the next. Many's
the time I've had a lightbulb moment as I've recorded values flowing into a
place I'd have sworn they couldn't get (or not into a place they should!).
It's tedious and long-winded, but the reward can absolutely be worth it.
Cheers!

Well, that's even worse -- because page3 can *never* be reached as

Mike, I'll heed your advice, since you haven't let me

every page, including page6 where it's transacted into
the database. I'm not sure why you say that
Well, I would expect it to persist in your success route, since you're not
doing any destructive assignments. However, I'm talking about your failure
route here, and with this extra assignment in place, every time that test
fails you are 100% guaranteed to destroy the value of $_SESSION['f1a']

Doubt it -- that's just me using PHP's alternative syntax for control
structures; in fact, if the rest of your script uses {} control-structure
delimiters, you should really use them in the above instead of : and endif,
since it's strongly advised not to mix the two forms. I just much prefer
the :-endif form and sometimes write it without thinking when it might be
more appropriate to use the {} form.

RE: [PHP] 'Code Snippets' you couldn't live without
Me too (tm)! This is a job for a good editor, with automatic name completion or abbreviation expansion. This gives you the convenience of shortcuts when coding, together with the full standard names when reading the source code at a later date! I think we've missed the point of my original question. Not that a discussion of good coding principles isn't welcome, but at the same time, there can be valid (if subjective) reasons for using shorthand functions in the way I mentioned in my original post. My valid reason is that I have RSI. To help alleviate that, I have a small handful of functions I commonly use many times over defined in a way that means less keystrokes. Across the scope of a project, that can mean significantly less typing, and marginally less discomfort. My hands thank me every time I use these shorthand functions. That having been said, and purist principles aside for the moment, I doubt there's an intermediate to advanced coder on this list who isn't comfortable with exploring include files to find out what a function does or how a class operates. I doubt half-a-dozen shorthand functions in that include file would place a measurable strain on the readability or maintainability of a project. Yes, I'm sure we can all generate extreme examples of code rendered utterly turgid and obscure by random and wholesale shorthand transformation. But let's be honest, you can make any suggestion or process seem ridiculous by rendering it in the extreme. The core PHP language is not without it's own shorthand approaches. Witness the ternary operator. At a glance, it's probably not obvious what it's doing when first viewed by someone new to PHP. Also witness the deprecation of variables such as $HTTP_GET_VARS in favour of $_GET etc. Or the .= concatenation assignment operator as a shorthand to $var = $var . ' added string.' Or the echo shorthand of ?=$var?. My point being, the most purist coder is almost certainly using shorthand methods built into the language. To suggest that these shorthand methods should never be extended, when approached sensibly and for good reasons, seems not only regressive, but also somewhat blind to the reality of the language itself. Of course, I realize this is a difficult position to defend. I understand that, in theory, using shorthand functions in this way is 'wrong.' But, after all, life is about compromise. Sometimes we get to choose the compromises we make, sometimes we don't. More power to those who struggle against compromise in this issue. You are a beacon of sanity and reason to us all.

Echo out your queries!
$query = insert into joke values('',.$_POST['joke_text'].,'date');
--- echo $query;
$result= mysql_query($query);
This will tell you what is going on, perhaps some of the information is not set? You
can even copy and paste the output to run against your mysql backend on the command
line to see if additional information/errors are present.

[PHP] Shorthand functions (was: Code Snippets' you couldn't live without)
Murray @ PlanetThoughtful wrote: with exploring include files to find out what a function does or how a class operates. I doubt half-a-dozen shorthand functions in that include file would place a measurable strain on the readability or maintainability of a project. I disagree on that. The problem here is not that the functions are short. The problem is, that their names gives absolutely no clue about what they are doing. mfr() can be mysql_free_result() but it also can be mysql_fetch_row(). So it's not only unreadable, it's also error-prone. Sure, it's possible to look up what this function is doing. But is it necessary? Everybody (even coders not knowing the mysql functions) can understand what mysql_free_result() is doing, without decyphering it first. But I agree that many PHP functions are named too long. But this is because they are non-OO functions living without namespaces. So if you don't use OO (where you may write something short like $res-free() you have to live with that, I fear. Or write shorthand functions, nobody can keep you from doing so. I just said, that it is problematic for more professional projects where new programmers may begin to work on at any time). And I agree that there are even some very short function names in PHP like nl2br(). This looks like a bad naming, but it is not really. nl is a well known shorthand for newline. 2 makes clear that it converts something. And br is named after the HTML-Tag. So this function name GIVES some clues about what it is doing. But for newcomers it may not be clear at the beginning what this function is doing. But after a quick lookup the newcomer can remember the meaning very well. And I think this is different with functions like mfr() and asl() which gives no clue about their meaning. when first viewed by someone new to PHP. Also witness the deprecation of variables such as $HTTP_GET_VARS in favour of $_GET etc. $_GET and $_POST are well named. It's clear what they are doing. Thank god their were not named $_HGV and $_HPV. Or the .= concatenation assignment operator as a shorthand to $var = $var . ' added string.' $a .= $b is not a shorthand of $a = $a . $b. The result is the same but the internal processing is totally different. $a .= $b is a lot faster then $a = $a . $b because $b is directly appended to $a. The second form constructs a completely new string and overwrites the old value of $a. At least this is the case if no optimizer is used. Maybe optimizeres are transforming the second form into the first form, don't know. So you can't compare this to a shorthand function. It was not introduced because coders are to lazy to write the long form. It was introduced because it is absolutely intuitive to do so if the language already has something like +=. But I can't tell if these operators were introduced into the C programming language (or wherever it appeared first) because lazy coders. ;-) Back to the intent rather than the form of my original question: what are the code snippets you can't live without?

[PHP] Sessions and threading
Hi everyone, I am attempting to write an implementation of Prevayler (http://sourceforge,net/projects/prevayler), which has originally been written for Java and provides a prevalance layer for storing objects using incremental log files and taking snapshots of in fixed time intervals. It seems the Java guys are widely using the implementation even for web applications. There are many advantages to using the system, backups and restores are very easy and reliable and it is very efficient for small sized projects, as the Prevayler guys claim about 9000 times faster than Oracle ;-) I have near worked out everything that has to be done, I think I am going to try and write it as a PEAR module for it to be available to everyone. I am stuck with a few concepts and I thought I might float the ideas here to get some feedback before I start scripting. The first part of the problem is that I need to be able to at all times maintain a readable set of objects in memory, I am planning to achieve that using session variables, but I hear that session variables can become very inefficient, how true is that? The other issue is running a thread that enable in some time interval to write snapshots from the log files that are being generated. Is it possible to have part of the script alive in some sort of a thread even after the script is dead. For example with the use of the sesssion variable. Any feedback is very welcome.

If you store huge variable names then it will be slower than if you store small ones. Same with the session variable values. PHP sessions variables are stored as a semi-colon delimited string of text, with other appropriate seperation characters and descriptions of the variables included. I minimize my session variable names to a single character and document them somewhere for future reference. I make sure and store minimum values for each variable, for example the integer 1 instead of the string 'true' or 'yes', things like that add up. Sessions are as efficient as you make them. Also, PHP doesn't have threads.

Very true. In Java (with Tomcat for example) you have a real session scope and application scope where you can put objects and directly access them. These objects are hold in memory and they are REAL objects between the requests. In PHP it's different. If a HTTP request is finished then the session (with all data including objects) is serialized and stored on the harddisk (or database or whatever the session backend is). On the next HTTP request the session is loaded from harddisk and unserialized. So new objects are created and filled with data from the harddisk at every request. It would be REALLY REALLY cool to have an application-server-like thingy in PHP. But as far as I know there is none. Correct me if I'm wrong. The other issue is running a thread that enable in some time interval to write snapshots from the log files that are being generated. Is it possible to have part of the script alive in some sort of a thread even after the script is dead. For example with the use of the sesssion variable.

[PHP] Very wierd issue with pdf's and rotating images
I have tried this with pretty much every pdf library available to use with PHP and all have the same results. 1. I create a new pdf. 2. I rotate a jpeg using gd's imagerotate 3. I output the jpeg to a new pdf page 4. I then output the pdf to the browser and/or to a file. When I view the pdf, the image that was embedded in the pdf page has a large black rectangular area taking up the first 1/4 of the image. If I do not rotate the image, there is no large black rectangular area. Anybody has an idea what's going on? Thanks, Brent
Re: [PHP] help in php script
PRINT is nothing but...
TimeRotateImage.php
?php
$curr_time = (localtime());
if ($curr_time[2] = 6 and $curr_time[2] = 17) {
print img src='image1.jpg';
}
else {
print img src='image2.jpg';
}
?
this script (something like this) should be called from another script like,
?PHP
print img src='TimeRotateImage.php';
?
did you get what i am saying? please let me know if you have some solution.
thanks

No. I must admit, It don't understand it. Let me try: You have a script
a.php which outputs this static content:
img src=b.php
b.php outputs the static content img src=c.jpeg
This can't work. You browser tries to download an image with the name
'img src=c.jpeg'. I think THAT's your problem and the reason why I
did not understand you problem. If you use a PHP script inside an img
src attribute then this PHP-Script must output an image. Complete with
content-type header and the image as binary data in the body.
Or another solution for a.php:
html
body
img src=?php include('b.php')? /
/body
/html
but I don't see the sense here. You can just do all this in one script:
?php
$curr_time = (localtime());
if ($curr_time[2] = 6 and $curr_time[2] = 17) {
$img = 'a.jpg';
}
else {
$img = 'b.jpg';
}
?
html
body
img src=?=$img? /
/body
/html
If I still misunderstood your problem then maybe your description was
not detailed enough.

Hi there please have a look the code below...I dont know wht am doing wrong
here... This code is suppose to show the number of jokes in a mysql database
and allows user to add a joke when the user clicks addjoke link. And when
the joke is added, it suppose to say that Joke inserted, Thank you and
list all the jokes below this line. So far am able to view all the jokes and
take the user to add joke page. But the problem is when the user clicks
insert joke button, it does not display the message Joke inserted, Thank
you and the jokes are not listed. Infact it does not give any error aswell,
it just stays on the add joke form page. I checked the database and no joke
is added. Working on PHP ver 4.3.8 with register_globals turned OFF and
Apache 1.3.31. MySQL ver 4.0.20a on winXP pro SP1. Recently i started using
registre_globals OFF and all these probs strted coming up. This code was
working fine with globals ON. But my hosting has it off. So need to do so. I
was able to fix all the other issues came coz of this global thing in this
code. But stuck on the issue i just mentioned. Any help would be GREATLY
appreciated.

well ofcourse it keeps the get variables as you put it. PHP_SELF is
the path and arguments that php was called with. use phpinfo(); to find
out which variables hold the real path, make sure to add some random
get variables when calling that script so you see the difference

A second problem, and why I want to create some PHP to mimic crypt() unix style passwords without actually using crypt() is due to the fact that this box is not my box and so the option of modifying the OS is currently not an option. Consider this thread dead unless someone else has a solution. Thanks for thinking it through. Your time has been greatly appreciated. A side note; I am amazed that no one else on this list can or is jumping into this discussion about using PHP to mimic PHP's crypt() function in order to create unix style MD5 passwords. I know it has been done before, and can be done probably many different ways. The idea of using system() or exec() to call MD5 is an option I will be looking into, however, I know there must be another option. I have considered rewriting my own version of crypt() to not use libmcrypt but the information on the C-like Zend language used to write your own embedded PHP functions is a bit vague in regards to me getting over the learning curve. My other option is to just move this to another server and then my existing crypt() based code will resume functioning as expected. I dont except a reply from Rasmus or Zeev, as they are extremely busy guys, however, I won't stop them if they are interested in this thread. Help me Obi Won, you are my only hope. LOL Take Care, Kris [EMAIL PROTECTED] Where is your PHP package coming from? If you've already been using the http://entropy.ch binary, maybe you should try compiling your own. Or get (and either compile yourself or just install binaries) it via fink (http://fink.sf.net/) which often gives you different options for libraries to use and such during install. Or any number of other options. I wonder if there is some build option or something setup in the configuration process that affects this. I seriously wonder how libmcrypt could have this sort of limitation under OS X, but I am not that type of programmer. I would encourage you to play with this and post your results to the php-general list as well as letting me know how it goes. -Galen On Nov 3, 2004, at 2:31 PM, Kris wrote: Galen, Thank you for the response. I understand where you are coming from; your use of MD5 hash. In short, my goal is to recreate crypt()'s method of creating unix style passwords without using PHP's built-in crypt() function... (as seen in /etc/shadow on a *nix server, ie. $1$sed$blaaah instead of standard MD5 hash which does not use $1$$ to store a seed.) Ultimately, my problem exists related to the server I am using, where the server's PHP crypt (using libmcrypt) returns with the fact that CRYPT_MD5 = 0 . In researching, I have been told that this is a limitation of Mac OS X, that there is no way to have libmcrypt support both DES and MD5 on this OS.. but I know there must be a way because it is easy to have a FreeBSD server use both DES and MD5. I had an old BSD box online for years.. where old account passwords in /etc/shadow were encrypted via two character salt DES. One day, I made a simple change to the box's config and then any new accounts created would use MD5. The coolest part is that any old passwords in DES could remain DES, and BSD's libmcrypt could determine if a passwd in /etc/shadow was DES or MD5 and handle accordingly. Obviously, this kept me from having to call clients and change their password so as to re-encrypt their respective /etc/shadow entry into MD5. I hope this email better explains my situation. I'll check out man md5 on the Mac box and see what I can figure out. In the meantime, if this email helps to generate any ideas which may be helpful in my current quest, your input would be most appreciated. Thanks again, Kris Galen P.Zink wrote: Kris, I'm not quite sure what you mean here. When I work with md5, I always have considered it to work like this: string - md5 = hash On any system, the md5 binary, md5 php function, and MySQL md5 (in most cases - though in certain situations you could have problems if you have a field of the wrong type or length) all work exactly alike. This is how I have always thought of md5 and considered it to be standard and I've never had a problem with it. I've made dozens of web and other php/mysql applications. There have never been seeds or anything else involved in my experiences. I do know that in some cases a salt is setup on certain unix

If I end up with only 512k free - something is very wrong, and I should disallow functions I know that eat up memory. There is a low probability that multiple connections will pass the test, and then consume the memory, so yes this is not 100% coverage. Maybe what I am seeing is actually a bug in the way that readfile() handles low memory situations. If there is not enough memory for internal functions to run, they should error, not crash your system. I assume that the way the converstation is moved is that there is not a way to see what free system memory is, without calling a command line function (free or mem). -Robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[snip] $query = select gallery_url,description from members limit .$limit[0].,.$limit[1]; the first time: limit 0,15 and the second time: limit 16,30 [/snip] from http://www.mysql.com/select The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must be integer constants. With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1): My guess is that you have 32 rows in the table, you started at 16 and asked for 30 records.

RE: [PHP] Strange query
The second limit parameter is the actual number of rows to limit to, and in most situations this is usually the same number (i.e. 0,15; 15,15; 30,15; etc). It is too bad this clause is not supported by some of the other databases I have had to use, it makes a convenient way of paging where the second paging parameter specifies the page size in terms of rows to retrieve (first parameter is the starting row number starting with zero).

Assuming that the pasting is done into a textarea/textarea on an html form, I believe the Textarea will limit the past to just text characters. I suppose this could be dependent on the browser. I don't know of any html input control that would allow blob (binary) values. I also don't know if MySQL will police things input to a text column to make sure they are valid ascii text characters.
