RE: [PHP] file from database work local, but not on server
Thank you for pointing out the security issue, I am aware of that. Was
sloppy not to use %d instead of %s as I did.
The database is exactly the same, and the data is correct in
$Row['filename']. I did create a copy and put it onto an other server, and
there it worked ok. Some files did work well, while others did not work at
all.
Is there anyone with reference of a small example of binary storage and
retrieval from database? I have performed working solutions for images
before, but this should support any file extensions (with exceptions of
course).
Best regards,
Peter Lauri

Best group member,

But when I run it on my server it does not start the download, and the
file
name is the location of the script instead of what I state as file name.
The first thing you should do is read this site:
http://www.phpsec.org
I could pass all sorts of bad things to $_GET['fileid'] and it will ruin
your database.
At least make it:
(int)$_GET['fileid'];
so if it's non-numeric, it will get converted to 0.
Can we assume the database is exactly the same and it's not that
$row['filename'] has the wrong data in it?

Re: [PHP] File downloads
Thanks to Tedd, Barry, George and others for help over download file problem. I'm going to receive an ACK if the file downloads correctly. In absence of such an ACK, a script would quitely remove the temporary files after a fixed interval of time. Temporary files have unique filenames. New problem: Is there a way for the server to notify the client that a new file has become available for download, provided the client was online in the past X minutes? This could be done if 1. The client queries the server after a set interval of time. I DO NOT WANT THIS FOR SOME SILLY REASON. 2. The connection is kept alive (?). With my current knowledge of PHP, I am not able to manage this. Cookies or sessions? Can't find a related example directly dealing with this issue. All wild ideas/links/examples are welcome. What changes would be required in Apache conf file (if any)?

[PHP] Gzinflate on a string that has been base_64 encoded in Windows
Greetings! I have a long piece of string that is apparently a PNG image which has been base_64 decoded in an XML file. I can retreive this string without problem. The string is in $mystra $pngdata = base64_decode($mystra); $pngdata = gzinflate($pngdata); When i try to gzinflate it , i get a warning that says data error and if i write pngdata to a binary file using fopen, there is 0 bytes (because of the warning). If i just write the base_64 decoded data to a binary file, then I can't open the file as a gziped file. (it is not a valid gzip'ed file) From the person who sent me the XML file, what I was told the base_64 decoded data will give me the deflated binary array for the image, which I would need to inflate using an InflaterInputStream, and as a result, I will get the PNG file that is represented in $mystra. I probably need to add some PNG headers to it and/or explode the base_64 decoded data and then add headers to it. I am getting quite lost here. Can anyone provide some hints please? Regards Venky

The problem I was trying to figure out was how the use of SID's cause SE's to fail and how that works. I figured that once I understand how that worked, then I could keep from doing it. I just needed to see for myself what it was. You know, one of my wonder why this works studies. While the problem wasn't present for me, which at the start of this I wasn't sure about, I did learn how it works and why SE's have problems with indexing url's that have ? in them. For those interested in this thread, this is what I believe is happening. If you have a web page that uses SID's in it's url, then it appears to a SE as something like this (using one of my sites as an example): http://ancientstones.com?PHPSESSID=1234 and not like: http://ancientstones.com/ So the SE grabs the page with the SID. The next time it travels your site, it see's: http://ancientstones.com?PHPSESSID=5678 and grabs that page. After a while, Google has numerous duplicate pages and has to pick one to be representative of your site and store all the others into it's supplemental index. Now when Google determines PageRank for your site, it does so by calculating how many sites link to your site (simple version). If Google has picked: http://ancientstones.com?PHPSESSID=5678 to be THE representative for your site, then you're sunk because no one uses a SID in their link to your site. Your site will always have a PR of 0 -- as it is with the referenced site. While the site ranks very high (currently #1) in a Google search for Custom Tile Medallions, it has a PR of 0. I was trying to figure out what was happening and if there was something I was doing in using php caused the low PR. I found that PHP wasn't the problem -- and now I know that.

I have a form that a user can use to edit www pages. Page content is stored
in DB as a HTML code. First user has to select, from select menu, which
page to edit. Then the selected page content html is retrieved to a
textarea where it can be edited with tinyMCE editor. Then there's two
buttons. Publish to save the edited content back to DB (no problems there)
and Preview to open the full page layout in a popup window. The problem is
that I can't pass the edited data from the textarea to the popup window.

Re: [PHP] Passing variables.
My Humble suggestion is possibly:
upon preview, actually post the edited data to a temp table, and then
pull the HTML from the temp table to display the preview page.
Currently you are passing the original content to the preview page.
And You might want to look to see if javascript has any functions for
escaping html entities for your GET variable..
To get the edited content you will need to get the contents of the text
area in the javascript, not pass the original PHP variable (as this will
be the original content)

A script PHP executes (serves the client), and terminates. Now if a new event occurs, how can the server notify the client about that event? Short answer: It can't. Longer answer: There are probably 100 ways to get close to the result you are looking for. For instance, you could have each page on your site look for a flag in a DB, or a file in the filesystem, or some other clue. Then when the user loads a new page, the page discovers the event, and notifies him. PHP is server side. So everything it generates, it does so on page load. There are PHP/Javascript solutions (like AJAX) that may be able to get closer to what you want. We would need more detail for a more detailed answer.

[PHP] order of elements in $_POST super global
Hello All, I'm using a form (method=POST) to collect 30 boolean values from the end user using a series of checkboxes in the form. The form is arranged in a table so that the 30 check boxes are not a long list but rather three columns (with related items columnized). The problem is when I iterate through the $_POST results: The order in which I wish to present the checkboxes to the end user is different than the order I want to have in the $_POST super global and subsequently when I dump that information out to a text file. What would be the best way to solve this? 1) Is there a way to present the checkboxes in a certain order, yet have the data transmitted into the $_POST super global in a different order? 2) Does it make more sense to process the $_POST super global array and reorder the items within the array? 3) Some other method?

Re: [PHP] order of elements in $_POST super global
Hi Dave, No, that is definitely a possibility. Right now I am using a foreach loop to iterate over the $_POST array and determine if each checkbox is checked or not, if it is checked, than a related piece of data is written into the text file. This makes for pretty compact code. I could as you suggest, simply check each element in the array manually using the associative keys rather than using a loop, that way I could do it in any order I wished, but the code gets rather long with a line for each checkbox. I anticipate this set of checkboxes/boolean responses may increase in the future also, so having the loop allows for some future-proofing. - Ben On 6/8/06, Dave Goodchild [EMAIL PROTECTED] wrote: On 08/06/06, Ben Liu [EMAIL PROTECTED] wrote: You can access the values in the $_POST array in any order, so if you know the checkbox names why not output them in the order you want?

[PHP] Re: order of elements in $_POST super global
I probably should add some more details to my question: The names of the form checkboxes could be changed from ie: bool_careers, bool_speaking, bool_internship, etc. to a single array bool_questions[], for instance. The problem with that is that I am using the form checkbox names later to process related data. Specifically, I am building a user-input based query. So if the form checkbox names are the same as the names of the variables in the database, it makes for easy creating of the query, since the names become associative keys in the $_POST array. I iterate through the $_POST array, checking each for true/false state. If the checkbox is checked, I add the associative key name to the query. Eliminating the checkbox names in favor of a numerical key only would make this more complicated. - Ben On 6/8/06, Barry [EMAIL PROTECTED] wrote: 1.

Also, I need to re-order the elements in a custom manner, not simply alphabetical or reverse alphabetical or some logical way like that, more like how the original form is presented, by related fields. More specifically, the form is for a membership system, the system collects typical demographic information like home street address, home zip code, business street address, business zip code. So the form presents related fields together: business with business fields and home with home fields (in columns). The problem is the POST method writes these response into the $_POST array in a certain order: not top-to-bottom, then left-to-right as a person would read the form, but left-to right, then top-to-bottom. The simple solution would be to reorder the form checkboxes so that they matched the desired output order of the text file, but then the user is presented with a disorganized, illogical form. I could eliminate the table and just list all the checkboxes in one big list, but again that makes for an ugly, user-unfriendly form. I could perhaps use some divs to make columns and float them, I'm not sure how the $_POST method would order the responses in the $_POST array. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

returns the contents of the file in an array. Also, I am able to print the

instead of printing results.
The following is the code that I try:
$name = $_POST[filename];
$lines = file($name);
$i = 0;
$len = sizeof($lines);
//echo $i;
while($i $len) {
//echo $lines[$i];

I think that the way the lines of the file are stored in the array may be
the problem, but I do not know what I am supposed to change. Any help would
be appreciated.
Thanks.

You might want to reexamine the need for your code. It appears that all
your code does is searches through a file for a certain line. Do you
need to do this manually? array_search() will replace your entire for
loop with a single function call, and it'll almost certainly be faster
to boot.

Re: [PHP] Re: order of elements in $_POST super global
yes, as I said in an earlier post, I used to have 30 if ($key)
statements, one for each checkbox, in the order I wanted to write them
in. This is not optimal because: (a) it is a ton of code, (b) the
checkboxes could in the future increase in number, change order, etc.
and then I would have to recode this section to match. The solution I
used to solve this was to remove the table, put all the checkboxes
into div elements, float them into columns and now they appear in
the same order as before when they were in a table, but they write to
the $_POST variable in the order that I want.

You can create a uniquely named id by using: $unique_id = md5(uniqid(microtime(), true)); and then use that name as a folder for each person submitting scripts OR use the unique id as a suffix for their cms file. Either way, it should stop persons from overwriting cms files. I would also suggest that you keep track of these id's in a dB. If you are still concerned about two people having the same unique, then you could search the dB to see if the recently created id exist. If it does, then generate another one. I use a similar method for making sure that the images I upload have unique names. hth's tedd -- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I probably need to add some PNG headers to it and/or explode the base_64 decoded data and then add headers to it. I am getting quite lost here. Can anyone provide some hints please? Hmm, a couple of things. Do you get it base64_encoded or decoded? You're using decode as both terms so it's confusing for us. Does the xml feed give you it inflated or deflated? gzdeflate will only work if it is already inflated with gzinflate. Can you get the other person to show you the code of how he puts the image into the xml feed?

[PHP] binary zero evaluates as true!?
Seriously guys... am I completely missing something important here? An empty array evaluates as false. The null character evaluates as false. The STRING 0 even evaluates as false yet a binary zero does not? Even better yet bindec() doesn't appear to be binary safe so it will work for a string representation of binary data where the 0's and 1's are ascii characters but pass it an actual binary string and it always returns 0.

The character '0' (zero) is not the same as a byte with all bits turned off.
(char) '0' = (binary) '0011' = ord('0') = (int) 48
'bindec' returns the decimal equivalent of the binary number represented
by the binary_string argument. Note the BINARY STRING key word. I'm
guessing a Binary String is a string consisting of the characters '0' or
'1' not bits. Each character is 8 bits, so a binary string is a
sequence of the characters #48 and #49 from the ASCII table.
The 'character' ZERO is written with bits 0011 in binary. This
binary could be interpreted as either a character or an integer. If the
binary is read as an integer, you'll get INT 48. INT 48 is NOT FALSE.
Casting from string to int to 'binary string' is done even when you
might not want it. Are you sure you are evaluating your binary
'' properly as you claim? Send a sample code, otherwise, see
the following example:
--
pre
?php
$zero = (string)'0';
$one = (string)'1';
var_dump($zero);
var_dump($one);
printf(char: %s, ord: %d, byte: %08b\n, $zero, ord($zero), $zero);
printf(char: %s, ord: %d, byte: %08b\n, $one, ord($one), $one);
// string(1) 0
// string(1) 1
// char: 0, ord: 48, byte:
// char: 1, ord: 49, byte: 0001
$zero = (int)'0';
$one = (int)'1';
var_dump($zero);
var_dump($one);
printf(char: %s, ord: %d, byte: %08b\n, $zero, ord($zero), $zero);
printf(char: %s, ord: %d, byte: %08b\n, $one, ord($one), $one);
// int(0)
// int(1)
// char: 0, ord: 48, byte:
// char: 1, ord: 49, byte: 0001
$zero = unpack('C', (string)'0');
$zero = array_pop($zero);
$one = unpack('C', (string)'1');
$one = array_pop($one);
var_dump($zero);
var_dump($one);
printf(char: %s, ord: %d, byte: %08b\n, $zero, ord($zero), $zero);
printf(char: %s, ord: %d, byte: %08b\n, $one, ord($one), $one);
// int(48)
// int(49)

Re: [PHP] binary zero evaluates as true!?
Are you sure you are evaluating your binary
'' properly as you claim? Send a sample code
alrightey then. the binary data itself is actually stored in a mysql
table. (mysql 5.1.9) the relevant part is the following column:
++-
| Field | Type
++-
| bit_string | bit(8)
++-
but of course there are others. assuming there weren't however, data
would be inserted into this table with a queries similar to:
INSERT INTO blah SET bit_string=b'0001';
INSERT INTO blah SET bit_string=b'0011';
INSERT INTO blah SET bit_string=b'0100';
this part appears to work great. i just discovered the bit type in
mysql myself and have been having great fun with it. just in case you
hadn't heard of it reference here: (*please* don't be insulted if this
is old news to you)
http://dev.mysql.com/doc/refman/5.1/en/bit-field-values.html
anyway, when this data is selected from the table the characters are
clearly being represented correctly, they show up unprintable in various
wierd ways and return correct values for bitwise operations. the
problem happens when you try to say:
?php
// assume this code is part of a method of a greater class that has a
member database handle already initialized...
--- snip ---
$bit_strings = array();
$rh = $this-_dbh-query('SELECT bit_string FROM blah');
if($rh !== false $rh-num_rows) {
while($bit_string = $rh-fetch_assoc()) {
$bit_strings[] = $bit_string;
}
$rh-free();
}
return $bit_strings;
--- snip ---
// ok so lets say you call this method and just for simplicity sake (no
its really not anywhere near this simple) *know* that the three values
above are the only things that get returned. lets say we know that we
will have an array of three values, which are the binary 1, binary 3,
and binary 4, we inserted above, in that order. in that case the
following check:
if($bit_strings[0] $bit_strings[1]) {
// blah
}
//evaluates to a binary 1 and is therefore true, as would be expected,
but this check:
if($bit_strings[0] $bit_strings[2]) {
// blah
}
// evaluates to a binary zero but STILL counts as true! (go ahead, try
it yourself)
?
Now two things are worth stating here. First is that its comforting to
see unpack('C',... in your sample code, because my fix for the problem
last night eventually turned out to be:
$bits = array_pop(unpack('C', ($bit_string_one $bit_string_two)));
settype($bits, 'integer');
if($bits) {
return true;
}
... and though it seemed to work the way i wanted i was previously
unfamiliar with unpack/pack and was worried i was approaching this
entirely in the wrong way. Thank you for that.
The second thing that needs to be said here is simply a re-statement of
the original, this time more verbosely. The list of things in php that
evaluate as false is as follows:
* the boolean FALSE itself
* the integer 0 (zero)
* the float 0.0 (zero)
* the empty string, and the string 0
* an array with zero elements
* an object with zero member variables (PHP 4 only)
* the special type NULL (including unset variables)
* SimpleXML objects created from empty tags
now, all i'm saying is that if, of all ungodly things, the literal
string 0 and empty arrays evaluate to false, isn't it appropriate to
expect a binary zero to evaluate to false as well? Maybe i still don't
get it. :(
thanks btw, for your time.

Jon,
You are correct about the behavior you are observing, sorry I doubted
your ability/methods. Here is a much shorter example of what you are
trying to do:
?php
// start with int '0'
$as_int = (int) 0x0;
var_dump($as_int);
// convert into to binary string
$as_binstr = (string) pack('C', $as_int);
var_dump($as_binstr);
// cast binary string as boolean
$as_bool = (boolean) $as_binstr;
var_dump($as_bool);
?
// int(0)
// string(1) !~unprintable~!
// bool(true)
You want to know WHY a single byte of all 8 bits set to '0' does not
evaluate as FALSE. I don't know the answer, but my theory is as follows:
Perhaps binary strings are not a normal everyday kind of string. If you
have a binary string, you probably got it from a binary place like a
file or stream. If you read a file and that file contains one byte and
that byte is all , then how is that FALSE when you got 1 byte
not 0 bytes. I might believe that a binary string should always be TRUE
if the length is greater than ZERO bytes in length. Since binary files
are not meant to be looked at, perhaps length is all that determines
their truth?
Oddly, if you start with this in the example above:
$as_int = (int) 48;
Then, the is_bool will be false! Ok, now I'm with you about odd
behavior and wanting a better answer ;-) You can't really use the
bitwise operators on your binary string either. From the manual:
Bitwise operators allow you to turn specific bits within an integer
on or
off. If both the left- and right-hand parameters are strings, the
bitwise
operator will operate on the characters' ASCII values.
I think the best bet would be to unpack the binary string into a format
that PHP will play nicely with. Most likely if you are looking at a
single byte, unpacking as an int is the way to go.
