[PHP] PHP/Mysql: Making binary field available for download - extra browser window ?
Hi all, Working on a PHP script at the moment where I want to be able to extract a file (PDF file) from a mysql database and force the popup of the File Download dialog, to allow the user to either save or open the document (ie. and bypass loading the file using the browser's plugin) I've found solutions on the net for doing this with a file using readfile() but if I can get away with it, I don't want to create temporary files... Here's what I've got so far (truncated...): ? .. // db query string extract the PDF file $result = mysql_query(select file_data from brochure where id=1,$connection); $row= mysql_fetch_array($result); $lengths = mysql_fetch_lengths($result); // Grab the file contents as returned from the db $pdf_brochure = $row[file_data]; // setup headers to force download of $pdf_brochure into crap.pdf header(Pragma: public); header(Expires: 0); header(Cache-Control: must-revalidate, post-check=0, pre-check=0); header(Cache-Control: private,false); // required for certain browsers header(Content-Type: application/force-download); header(Content-Disposition: attachment; filename=\crap.pdf\; ); header(Content-Transfer-Encoding: binary); header(Content-Length: . $lengths[0]); // send the file to stdout print $pdf_brochure;// problem might be here exit(); ?

No. Those functions will retrieve the webpage exactly the same as your browser does. What would test be?

So if you have:
option value=test1Test 1/option
option value=test2Test 2/option
You want:
$test1 = Test 1;
$test2 = Test 2;
??
preg_match_all('%option
value=[\']*([^\']+?)[\']*\s*(.*)/option%isU', $text, $matches);
That will give you an array that looks like this:
Array
(
[0] = Array
(
[0] = option value=test1Test 1/option
[1] = option value=test2Test 2/option
)
[1] = Array
(
[0] = test1
[1] = test2
)
[2] = Array
(
[0] = Test 1
[1] = Test 2
)
)
From there you should be able to work out what to do..

Re: [PHP] OO purism sucks - this is a rant for anyone who is allergic to that kind of thing...
hi Rasmus,
I understand the point you made below - you have made this argument before
and I, for one, accepted it as valid when I first read the discussion
on internals - which is why I avoided ranting about that (and changes like it)
But I am wondering what if any your views might be on the original rant (mine)
regarding purism/strictness that [I feel] is creeping into php for no good
(read 'pragmatic') reason?
as an example - I have in the past argued that discontinuing the ability to
define static methods in interfaces was against the grain and was given the
reply 'you don't understand OO fix your code' - in the last couple of weeks
static interface methods were reintroduced to help in a situation highlighted
by Derick R. I have had pretty much the same experience regarding late static
binding - to which (though nothing to do with my pleas) has finally been
capitulated
for inclusion in php6 not inducive to an optimal uptake of php5 which given
the length of time it's been out is rather dismal when compared to the speed at
which php4 was taken up.
if you agree at all with my postulation then maybe you also see some need
to address the issue?
kind regards,
Jochem

Stuff like this is a bug in your code. It has nothing to do with purism:
function inc_arg($arg) {
$arg++;
}
inc_arg(3);
You have specifically defined your function to modify the argument yet
you pass it something that has no storage and thus there is no way to
use that modification. For the most part I agree that we need to keep
the language as flexible and forgiving as possible, but where we are
able to detect code that obviously doesn't do what the programmer
intended, it is tremendously helpful to get a descriptive error.
As far as functions returning references, you are right that returning a
literal there sometimes makes sense, but this can also hide a bug which
is why this only throws a notice.
You could argue that we could try to look ahead and see what is actually
done with the passed argument to see if it is modified, or that we could
try to figure out whether the returned reference is actually used as
such, but that is technically extremely difficult given the way things
work internally. So given the choice between ignoring extremely
suspicious code like this and throwing an error/warning, I'd rather be
told about it and in the edge cases where I really do want the
equivalent of a NOP in my code, it isn't that hard to force it by adding
a dummy storage variable along with a comment explaining why you need to
do that.

Hi guys, I'm trying to retrieve a certain variable from a site. Here it goes: The site has a SELECT box that is dynamicaly updated, I need to put a script running that will retrieve the specified SELECT with its contents, that are labels and values. Is there a way to retrieve the page and then select just one line of the code, discard the rest and then retrieve from this line the values? Here goes the SELECT : SELECT title='navigation' Name=navigating onChange=self.location = '/s/2318355/'+ this.options[this.selectedIndex].value + '/';option value=1 selected1. Nameoption value=2 2. Name/select I need to get something like this: $select = navigating; $label1 = 1.Name; $value1 = 1; $label2 = 2.Name; $value2 = 2; Remmembering that the SELECT is dynamic so I need also to check how many labels and values there are and store them into variables. I getting a really hard time doing this. I thank any imput you guys can give me. Thanx, Rodrigo -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] OO purism sucks - sell me on PHP5?
I'm kind of coming from the outside here, so forgive my ignorance on some matters. I have some OO experience, just not with PHP and have only worked with PHP4 so again.. kind of on the outside of all this. Rasmus, you make a great point here. OO is structured and is all about constraints whereas PHP tends to be rather flexible. So OO in PHP doesn't mean that it should comprompise the idea of a structured development method. It's just part of PHP's philosophy of allowing developers to choose their method of skinning the proverbial cat. It seems that one of Jochem's main complaints about it isn't so much the rules and structure, but the idea that he was told his code was wrong and he needed to redo a good chunk of his 2 years worth of development (or any of this code) to PHP5's OO standard then a short time later he's told that someone else had the same problem and the 'standard' was changed to accomodate. But hey.. stuff happens. Sometimes concessions need to eventually be made when there's no other way. So that leads me to the 'sell' part of my altered subject line. Rasmus said: People are not upgrading to PHP 5 because PHP 4 works just fine for them and they haven't yet discovered things like SimpleXML and some of the other killer features of PHP 5. So I've read some of the new features on PHP5 and am still not sold on upgrading. As was stated, what we've developed so far works great and there's no real incentive to upgrade. But upgrades are inevitable so in the interest of planning for the future, I'm looking at PHP5. Our XML routines work fine, but since you mentioned SimpleXML, I'll take a closer look at it. What are some of the other killer features of PHP5 that I may be sleeping on here. If it ain't broke, don't fix it works for a while, but if there are easier and/or better ways to do things in PHP5, I want in! So someone sell me on this from the point of view of someone who's upgraded and has learned the joys of PHP5. So far what I've found online has been little more than a list of new features without an idea of how much of a headache they're going to save me in the future.

Re[2]: [PHP] Extended Ascii Characters
Richard: The discussion was in February, I looked and couldn't find what I remembered. So, I'm thinking that the coder sent it to me directly, but I searched my files and again I came up with nothing -- it's not like me to lose code. What I remember was a function that took Unicode HEX and produced the html entities, like those found here: http://www.roborg.co.uk/html_entities/ I will send you off-list what code I have that comes close, but perhaps the original author might resubmit his code. It was a fairly simple look-up and replace table, except the table was very extensive. It was a nice piece of work. tedd PS: For sake of clarification, ASCII ranges only from 0 to 127 DEC (HEX 0-7F). While 128-255 DEC is commonly referred to as Extended ASCII, it isn't officially ASCII -- as such, there are differences between OS's (i.e., win v mac). However, Unicode includes everything and handles all code-points from 00 to FF and divides those into various char-sets based upon various criteria (i.e., language, use, etc). So, the new words on the block are code-point and char-set. --- previous --- At 5:08 PM +1000 6/2/06, Richard Luckhurst wrote: Hi Tedd, I had a hunt in the archives and couldn't find anything.

This other script cannot/should not be modified? Then you can
either use shell_exec to execute the script and get the output
$message = shell_exec('the/other/script.php');
or use file_get_contents():
$message = file_get_contents('http://domain/script.php?a=b');
or if the other script is also php look into output buffering.

I've found online has been little more than a list of new features without an idea of how
much of a headache they're going to save me in the future.
To me the main user-visible benefits of going to PHP 5 are (ignoring the
OO changes for now):
1. Simplexml
eg. One-line RSS parser (of Flickr's upload queue feed)
$url = 'http://www.flickr.com/services/feeds/photos_public.gne';
foreach(simplexml_load_file($url)-entry as $it) echo $it-content;
2. Much improved DOM support
eg. various things you can do to a DOM
// First, load your XML document into a DOM
$dom = domdocument::load('test.xml');
// Apply a stylesheet to the dom
$proc = new xsltProcessor;
$proc-importStyleSheet($domxsl);
echo $proc-transformToXML($dom);
// xpath query on the dom
$ctx = new domXPath($dom);
$result = $ctx-query('/top/[EMAIL PROTECTED] 3]/foo/text()');
foreach($result as $node) {
echo $node-nodeValue;
}
// pull it into simplexml and access it
$s = simplexml_import_dom($dom);
echo $s-child[0]-foo;
3. xmlreader/xmlwriter
eg. SAX document validation using xmlreader
$reader = new XMLReader();
$reader-open('test.xml');
$reader-setParserProperty(XMLReader::VALIDATE, true);
while($reader-read());
echo $reader-isValid();
4. PDO
eg. Prepare execute against MySQL with named parameters
$pdo = new PDO('mysql:dbname=testdb');
$sql = 'SELECT name, colour, calories
FROM fruit
WHERE calories :calories AND colour = :colour';
$prep = $pdo-prepare($sql);
$prep-execute(array(':calories' = 150, ':colour' = 'red'));
$red = $prep-fetchAll();
5. SOAP
eg. Exposing your PHP code as a SOAP web service
function Add($x,$y) {
return $x+$y;
}
$server = new SoapServer(null,array('uri'=http://test-uri/;));
$server-addFunction(Add);
$server-handle();
6. SPL
eg. Iterating over entries in a directory
$dir = new DirectoryIterator('.');
foreach($dir as $ent) echo $ent;
7. Filter
eg. Define a default filter and use form input safely without cluttering
up your code with htmlspecialchars() calls everywhere and provide
easily auditable access to the unfiltered data
php.ini: filter.default = special_chars
echo $_POST['data'];
$raw = input_get(INPUT_POST,'data', FILTER_UNSAFE_RAW);
8. Native Date/Time mechanism
Date/time functions now behave exactly the same way on every platform
regardless of the differences in locales if you choose to use the native
mechanism.
Beyond that the compiler produces smaller opcode arrays and the executor
is faster. Not a directly visible thing, and this is still improving,
but definitely a plus.
Note that for all of this I am referring to PHP 5.1.x, not 5.0.x.

[PHP] Re: Retrieving Content
Actualy I went a slightly diffent way, I tried to use the file() like
on the script below and I get the content of the whole page but when I
try to get a single line from the array it all goes sideways. Here
goes the script with the correct urls, remembering that I'm using it
on the local server thats why I save it on the file to see if its
getting the right content:
$fc = file('http://www.fanfiction.net/s/979216/1/');
$f=fopen(some.txt,w);
foreach($fc as $line)
{
if ($line[85])
{ //look for $key in each line
fputs($f,$line[85]);
} //place $line back in file
echo $line;
}
It shows the whole page but saves on the file something grambled that
I cant identify what it is.
Iknow that when opening the html result of the page that I need to get
the content its the second SELECT, and its actually on line 86, but
since the PHPEd dont use line 0 it should be right. Or I'm missing
something...

I don't think I'll ever learn to like SPL or try/catch...
Ok, I think my example was a little too simplistic...
You could of course create multiple catch blocks and test for various errors.
In this simple example the catch might loook like
catch(Exception $e){
echo 'Uh oh: '. $e-getMessage();
}
This would tell you what the problem is perhaps.

[PHP] Try XMLWriter ... was Re: [PHP] OO purism sucks - sell me on PHP5?
[EMAIL PROTECTED] wrote:
What are some of the other killer features of PHP5 that I may be sleeping on
here.
You have got to get your hands on XMLWriter. I don't write any XHTML
inside php any more. I've wrapped the XMLWriter object inside my own
object and now I can create 100% properly escaped XHTML without ever
using a '' or '' symbol:
?php
$XML = new XTag('a', 'href', $href, 'title', 'This is a test such.');
$XML-push('img', 'src', $img_src, 'width', 100, 'height', 50, 'border', 0);
$XML-pop(2); // img, a
print $XML-toXML();
// outputs: a href=[$href value here] title=This is a test amp;
such.img src=[$img_src value here] width=100 height=50
border=0//a
?
XMLWriter handles:
* the escaping of characters to ensure I'm writing XHTML compliant code,
* tags are guaranteed to open and close in the proper nested order,
* content is encoded with UTF-8 encoding,
* indentation of XHTML is optional
* php code is legible without needing to backslash double and single
quotes
* PECL version of XMLWriter (gonna be in 5.2) contains ability to
write raw (unescaped content) into your xml so you can merge
already-created snippets of XHTML into your XHTML.
* good for creating syntax valid XHTML 1.0+ strict output
* good for creating syntax valid XML documents
There are a couple other 'gotta have' features of 5.1+ that are cool ...
like PDO etc. Sadly, all that is cool appears to be cutting edge and so
documentation and examples are seriously lacking. I find myself reading
the source of many extensions just to try to figure out how to use
them. Maybe that's a sign I'm upgrading too often? Of course, everyone
is using 5.1.4 with XMLWriter from PECL, right?

[PHP] Re: Retrieving Content
Rodrigo de Oliveira Costa wrote:
Actualy I went a slightly diffent way, I tried to use the file() like
on the script below and I get the content of the whole page but when I
try to get a single line from the array it all goes sideways. Here
goes the script with the correct urls, remembering that I'm using it
on the local server thats why I save it on the file to see if its
getting the right content:
$fc = file('http://www.fanfiction.net/s/979216/1/');
$f=fopen(some.txt,w);
foreach($fc as $line)
{
if ($line[85])
{ //look for $key in each line
fputs($f,$line[85]);
} //place $line back in file
echo $line;
}
It shows the whole page but saves on the file something grambled that
I cant identify what it is.
Iknow that when opening the html result of the page that I need to get
the content its the second SELECT, and its actually on line 86, but
since the PHPEd dont use line 0 it should be right. Or I'm missing
something...
Thanks,
Rodrigo
HTML can't be parsed line-by-line since even a single tag can be broken
up onto multiple lines. And also, if ($line[85]) simply checks if
there is a character in position 85 of the line. It looks like your code
is reading in a file, checking if each line is at least 85 characters
long, and then writing it out again.
I suggest you read in the whole file using file_get_contents(), and then
do the regex matching or strpos matching that I described in my previous
message. Also keep in mind that as of PHP 5 there is a
file_put_contents() function that lets you dump out a file in one go
(with higher performance than doing it yourself). php_compat also has a
copy of that function for other versions of PHP, although of course they
do it in PHP code so the performance benefits are slightly less.

[PHP] Retrieve output from HTML or PHP file
Can I do the below to an URL, like retrieving the output of a site and
store it on a variable?
Thanks,
Rodrigo
Hi Peter,
Ah, I understand now.
If the file echo'ed it's output you could do:
ob_start();
include('file.php');
$output = ob_get_contents();
ob_end_clean();
or:
$output = exec('script.php');
(but make sure you use escapeshellarg /or escapeshellcmd where
applicable for security reasons).
first method would be better, more robust and more portable.

[PHP] SPL Iterator and Associative Array
I'm going to try my best to explain what I'm trying to do.
I have my own class that has an array member. This class itself implements
Iterator. One of the fields in the array is itself an array that I would
like to iterate over. Here's some code:
class Folio implements Iterator {
$projects = array(
array(
'title'=,
'clip'=,
'small'=array('1','2','3')),
array(
'title'=,
'clip'=,
'small'=array('0','1','2'))
);
function title($x){
return current($this-projects[$]['small']);
}
function smalls($x){
return $this-projects[$x]['small'];
}
}
And I'd like to do:
foreach($folio-smalls() as $s){
echo $folio-title();
}
However, at the moment, doing this doesn't increment through the 'small'
array. It loops the correct number of times. But it only prints the first
one. I assumed it was because it wasn't moving the internal array pointer.
So I tried making the method smalls return a reference. Doing that made the
following work perfectly:
reset($folio-smalls());
while($s = current($folio-smalls())){
echo $folio-small();
next($folio-smalls());
}
But trying the foreach loop printed the second, and third elements, then
tried to output one passed the end of the array.
From what I understand, foreach simply expands to
reset();
while($x=current())
{...; next();}
What do I do?
