Where did you hear that?
$ cat go.php
<?php
session_start();
echo 'sess id is ' . session_id() . "\n";
$_SESSION['abc'] = '12345';
print_r($_SESSION);
session_start();
echo 'sess id is ' . session_id() . "\n";
print_r($_SESSION);
$ php go.php
sess id is de0474e8080c0143b92ddb426c2c580d
Array
(
[abc] => 12345
)
sess id is de0474e8080c0143b92ddb426c2c580d
Array
(
[abc] => 12345
)
(Of course you'll get a different session id but nothing else will change).

A successful download across all browsers requires proper headers.
I do not have time to fix your code, but here are some suggestions,
which for me do successful downloads regardless the browser -
header("Content-type: $mime");
/*

* This fixed the download in IE 7
*
* EXPLANATION
*
* Without this direct point to the URI
* leads to attempt to download index.php, which leads to nothing.

header("Cache-Control: post-check=0, pre-check=0");
/*

header("Content-Disposition: attachment; filename=\"$file\"; size=$size");

Hi
I'm using Ioncoder, the structure for the classes is that I have a "master"
library folder in every client root containing all classes, but
unfortunately the filename is not the same as the classname (some files are
but not all) so no luck matching classes with filenames.
The code I use to scan the files are:
$rows = file_get_contents($path);
if (preg_match('#^(?:abstract |final )?class (\S+) #m', $rows, $m)) {
...
}
The files just looks totally scrambled when they are encoded, so this is not
working at all obviously.

Hi all,
i'm wandering if there's some intelligent way to delete old records
from a mysql table without using cronjobs (i can't), using PHP.
This table has a field which stores the value returned from time(), and
i want to do
mysql_query("DELETE FROM `table` WHERE `time`<='".(time()-86400)."'");
at periodical intervals (say every 15 hours). Thanks for any hint :)
Ciao,

You could have it triggered manually, or by your website say. Or you
could (if you have it) use a cron job on another machine. You must of
course be able to connect to MySQL remotely from this box if you choose
that route. Depending on your MySQL version triggers may be able to do
it too - but I've not used these so I couldn't say for sure.

I can't help your wandering around, but if you are wondering about
how to periodically delete records from a dB without using a cron,
then this will work.
Create and set a field for "last_deletion" to current time.
When users accesses the dB, then have the process check current time
with "last_deletion" and if the "last_deletion" is greater than
current time plus 15 hours, then run the "delete old records" routine
and reset the "last_deletion" to current time.
That way, users accessing the dB will trigger the "delete old records" process.
Cheers,
tedd

What version of MySQL? If it's >= 5.1.6, you can use the mysql event scheduler.

Depending on how many records you need to delete, having it triggered by
your website may not be the best option. I suppose you could fork a
different process though.

Depending on how busy your website is, you might not need to alter you
schema at all. ie Add a query to one page of your website that only runs
when it's minute 1 of any (or a particular) hour. Depending on how busy
your website is it may mean that the query runs too much or too little.

Re: cron jobs... this is my recommended solution. They don't need to
be set up on the same server as your website. They can be on any host,
and can just use curl to call a particular url on your site at set
intervals.

The answer and link that Ted gave you should help you out, but one
thing I'd suggest as to why it worked on your server and not your
client's is that your client is using a Windows server. Chances are,
your server is running a *NIX flavor.

A loop can be used in the above assignment code to assign the
properties. You just need to check if the key is prefixed by the null
byte:
<?php
class Foo
{
protected $aaa = 'aaa5';
protected $bbb = 'bbb5';
protected $ccc = 'ccc5';
static function importFromPhp4( $serialized )
{
$array = (array)unserialize( $serialized );
$import = new Foo();
foreach( $array as $key => $value )
{
if( $key[0] !== "\x00" )
{
$import->$key = $value;
}
}
return $import;
}
}
?>

Robert, thanks very much for your detailed explanation. This makes
sense as I've wrapped my brain around protected and private property
types.
I think I'll be leaving them as public members for performance
reasons. Down the road, I may add special handling for certain members
that should be private and protected. The __sleep() and __wake()
function should come in handy for that.
Thanks again.

I think that’s perfectly fine.
You didn't read his problem correctly. Try the following:
foo.php4 (Run via PHP4)
---------------------------------------------------------
<?php
class Foo
{
var $aaa = 'aaa4';
var $bbb = 'bbb4';
var $ccc = 'ccc4';
}
echo serialize( new Foo() );
?>
Now using the output from the above script paste it into the $foo4 var
in the following script (it should be as shown in my example below):
foo.php5 (Run via PHP5)
---------------------------------------------------------
<?php
class Foo
{
protected $aaa = 'aaa5';
protected $bbb = 'bbb5';
protected $ccc = 'ccc5';
}
$foo4 =
'O:3:"foo":3:{s:3:"aaa";s:4:"aaa4";s:3:"bbb";s:4:"bbb4";s:3:"ccc";s:
4:"ccc4";}';
$foo4 = unserialize( $foo4 );
var_dump( $foo4 );
?>
The reason this happens is because serialize tracks the var type. In
the
PHP4 case, no var type is possible and so no var type is stored. As
such
the unserialize function does what PHP code does... it presumes
public.
However, at a low level within the PHP binary, there is no check to
see
if the property exists in another form. For instance, to unserialize,
the unserialize code instantiates a new Foo object when it encounters
the Foo instance in the serialized data stream. When it is
instantiated
the protected members are initialized. But protected members are
stored
differently internally than public members, and so, I presume for
speed,
PHP didn't bother testing for the existence of both, but rather gives
one precedence over the other when a property is requested. So
happily,
the different variable types are co-existing. Some pbrief testing
shows
that private members are getting precedence. So this is obviously an
issue for all the old serialized data once you promote the var type to
protected.
So what CAN you do??
You can choose not to change the properties to protected.
You can use use an import technique to import the serialized data and
resave it in the PHP5 format:
foo.php5 (Run via PHP5)
---------------------------------------------------------
<?php
class Foo
{
protected $aaa = 'aaa5';
protected $bbb = 'bbb5';
protected $ccc = 'ccc5';
static function importFromPhp4( $serialized )
{
$array = (array)unserialize( $serialized );
$import = new Foo();
$import->aaa = $array['aaa'];
$import->bbb = $array['bbb'];
$import->ccc = $array['ccc'];
return $import;
}
}
$foo4 =
'O:3:"foo":3:{s:3:"aaa";s:4:"aaa4";s:3:"bbb";s:4:"bbb4";s:3:"ccc";s:
4:"ccc4";}';
$foo = Foo::importFromPhp4( $foo4 );
var_dump( $foo );
?>
That should solve the problem.
Cheers,
Rob.

If you're moving your entire system over to PHP5, then a one time pass
through the database may be optimal. A simple loop to grab each record,
import it, re-serialize and save it should do the trick. And from my
brief test where I found private members have precedence over public
members, it seems it might be the most efficient solution also... in the
long term.
Cheers,
Rob.

Christian,
Interesting to know, however the OP's question was about using PHP to run
the scanner, not on the already present PDFs in the FS. Can your solution
handle the scanning? Could / Would you be willing to share you solution on
merging the PDFs? That is something that I am interested in...
Thanks,

That's not how I read the question, but clearly I could be wrong...

I've been meaning to suggest that the OP look at pdftk (http://www.accesspdf.com/pdftk/
) - though it's not a PHP solution, it's a great tool for working with
PDFs. It can make otherwise tedious, time consuming tasks with PDFs
quick and easy.

HI!
I would like to have some question.
For example,
I am in http://example.com/?12324242
I would like to REDIRECT from http://example.com/?1312323232
to http://example.com/
I can REDIRECT from http://example.com/index.php to http://example.com
Please do tell me how I can redirect!
This is the sample what I test below!
<?php
if ($_SERVER['REQUEST_URI'] == '/index.php') {
header("HTTP/1.1 301 Moved Permanently");
header("Location: http:///example.com/";);
exit();
}
?>

1) Why? Redirects should be avoided where possible for performance
reasons.
2) If you have to then the code you have will work but you need to
check $_SERVER['QUERY_STRING'] rather than REQUEST_URI.

Well, in your example code, you have 3 forward slashes...
What that a typo in your example, or is that cut/paste from your script?

Didn't this topic get covered several months back. I always do redirects
so as not to bugger browser history, titles, indexing, etc. If someone
requests a page and they need to be logged in, I redirect to the login
page, I never just present the login page... that's just incorrect from
a hierarchical and semantic point of view. Similarly, if I'm doing 404
handling with fuzzy request sniffing to determine what was actually
requested, I again perform a redirect once I've ascertained what was
probably desired. If you don't, then Google and other search engines
will index these malformed URLs instead of the correct URL.
Cheers,
Rob.

Rocket science it ain't!
But I repeat... this seems to be a completely pointless redirect. The
user is already requesting the index page, so why redirect them back
to the index page?

The correct response to a 404 page is 404. No arguments. If you
redirect missing pages then your site effectively contains an infinite
number of pages. By all means display a useful page when you return
your 404 but not marking it as a missing page does little if anything
for your SEO rank and absolutely nothing for your users.
IMHO if you're going to use a semantic argument to defend one point
you need to carry that attitude throughout.

What about using .htaccess for redirection for example, to redirect a single

Hello,
I am querying uploaded files using the php function
mime_content_type($file), passing the absolute path to the file in the $file
var.
The result I get back is "text/plain" which clearly isn't what I expected -
or hoped for.
Is this php related or could it be Apache's config missing something like
"AddType application/x-Shockwave-Flash .swf" ?
I have no access to Apache's config as the server is managed but I really
would like to filter files based on mime type as opposed to file extensions
- and also get to the bottom of it.
Thanks,
Bob

my question is about validation using php. i am validating a username
which a user would enter and clicks on a image to find
if that username is available. example if a user enters abc#123 php
file is reading this value as abc ONLY which i do not
want instead the php file should read as abc#123. follow is the
sequence of pages. please advice the solution.
first page = register.php here a user enters a username and clicks on
an image to find out if the username is available or
not. using a javascript function of onclick i am reading the value
entered in the form in javascript as
=============================================
var useri = document.registrationform.username
var valueofuseri = document.registrationform.username.value
var recui = /^\s{1,}$/g;
if ((useri.value==null) || (useri.value=="") || (useri.length=="") ||
(useri.value.search(recui))> -1)
{
alert("Please Enter a User Name")
return false
}
window.open("checkusernamei.php?theusernameis="+valueofuseri,
"titleforavailabilityi", "width=680, height=275, status=1,
scrollbars=1, resizeable=yes");
============================================
second page = checkusernamei.php = this file uses GET to read what was
entered in the form.
============================================
$username = $_GET["theusernameis"];
if( $username == "" || !preg_match("/^[a-z0-9]+(?:_[a-z0-9]+)?$/i",
$username) )
{
echo "username is blank or has special characters";
}
============================================
the # sign is being ignored only if the image is clicked in order to
check the username, if the user enters abc#123 and
clicks the submit button without clicking on the checkuser image
button then my php validation for username shows an error
message.
==============================================================
if( $username == "" || !preg_match("/^[a-z0-9]+(?:_[a-z0-9]+)?$/i",
$username) )
{ echo "display error message for username"; }
==============================================================
now the problem is with clicking the image only and passing using GET
method how can i fix this problem.
please advice.
thanks.

You need to encode the # mark. It is a special character in URLs.
Example (not a real url):
www.php.net/documentation.php#help
That #help points to an anchor in that page.
Try using the javascript escape() function.
