From: Michael Stroh
I'm maintaining various php scripts on a server that was originally
configured to have magic_quotes_gpc turned on. The installed php
version
is 5.2.6. I've read that magic_quotes_gpc is deprecated in 5.3 and
continuing to use it is highly discouraged. I've ran into a few
fields
that I believe this is causing issues with so I'm considering turning
it
off but am wondering what steps should I take to make sure that
nothing
breaks and what should I look out for? Also, is it still a good idea
to
turn off since this installation isn't yet at 5.3?
It's a good idea to turn it off as soon as possible. However, you need
to test your site to make sure it won't broke something first.
There is a way to undo the results of magic quotes. We have implemented
it on a number of sites so that we won't care when it gets turned off.
Early in the script we have the following code:
// If magic quotes is on, we want to remove slashes
if (get_magic_quotes_gpc()) {
// Magic quotes is on
$response = stripslashes($_GET[$key]);
}

You have to test not only your site, but also the data that possible
lies in the database, if any.

Many people use this approach or something similar and when you use
that from the beginning of production, it's not a problem.
If however you are going to turn Magic Quotes off while running a
production system where it was previously turned on, you might run into
problems.
Don't trust this method blindly. You have to remember that stripslashes
will only remove a single slash. If, for some reason, data has been
pulled out, updated, and re-inserted it may contain several slashes
(because each time Magic Quotes will add a new slash).
If you are turning off Magic Quotes on a system that has been running
with Magic Quotes on, you have to inspect the data manually to be safe.

Hi..
For my curl_exec problem,
http://readlist.com/lists/lists.php.net/php-general/16/81195.html
http://curl.haxx.se/mail/lib-2011-02/0101.html
I need to know if this simple test will cause data to be sent every 25
seconds _over the wire_.
?php
set_time_limit (0);
error_reporting (E_ALL);
for ($i=0; $i((3600+1800)/25); $i++) {
echo '.';
ob_flush();
sleep (25);
};
echo wanted-data;
?
reason; i just can't get my media import routines that only send
sporadic status messages to work for big video files.

Hi
I need to generate some PDF reports (1000s). Part of the report is a set of
bar charts (the results of a questionnaire). Each question has the same 5
answers (v.bad, bad, ok ,good, v.good) and the chart is the % distribution
of the answers.
My plan is to create a HTML version, using some graph drawing* (saving a
copy of the HTML to disk), creating a PDF version using html2pdf (saving a
copy to disk and emailing to the recipient).
I think html2pdf can handle this. But I have not had much success finding
something to draw my graphs. Any (free) simple libraries out there I could
be pointed towards?
Thanks!

RE: [PHP] Bar Charts in PDFs
Hi Tom, Have a look at the library called 'pChart': http://pchart.sourceforge.net/ While it's a bit old, it generates very nice looking (anti aliased) charts, using the default GD library.

well, first off i should be using php:flush() instead of
php:ob_flush() in my simple test.
second;
http://www.php.net/manual/en/function.flush.php :
Several servers, especially on Win32, will still buffer the output
from your script until it terminates before transmitting the results
to the browser.
.
aargh..
well, i'll have to dig deep here.
will inform you of any relevant progress, digest style

RES: [PHP] Bar Charts in PDFs
Tom: You can try: http://www.tcpdf.org/ to generate pdf. And http://jpgraph.net/ To generate chart. EX: to add a image to a pdf document: $pdf-Image( '/home/peter/test.png', 127.78, 15, // left and right 74.93, 6.42, // width and height 'PNG', '', 'T', false, 300 ); With this tcpdf i create a legal documents for Brazilian government.

[PHP] Help! Made a boo-boo encrypting credit cards
Hey all -
I'm using mcrypt to store credit cards into MySQL. About 90% of them decrypt
fine, but about 10% decrypt as nonsense (b1�\�JEÚU�A��� is a good example).
Maybe there is a character that appears in about 10% of my encryptions that's
not being encoded properly???
// Encryption is set up at the top of the script:
$crypto = mcrypt_module_open('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($crypto), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size($crypto);
$key = substr(md5('my_funky_term'), 0, $ks);
// When the card number is collected by the form, it's encrypted:
$cc_number = addslashes($_POST['cc_number']);
mcrypt_generic_init($crypto, $key, $iv);
$cc_encrypt = mcrypt_generic($crypto, $cc_number);
mcrypt_generic_deinit($crypto);
// This is written to the database:
$query = update accounts set cc_encrypt='$cc_encrypt', encrypt_iv='$iv',
other_fields='$other_stuff' where id='$account_id' limit 1;
$result = mysql_query($query) or die(mysql_error());
Both the cc_encrypt and encrypt_iv fields are tinytext, latin1_swedish_ci,
MyISAM, MySQL 5.0.91
In another script, when I retrieve, I first set it up at the top of the script
exactly like step #1 above, then retrieve it like this:
mcrypt_generic_init($crypto, $key, $row['encrypt_iv']);
$cc_number = trim(mdecrypt_generic($crypto, $row['cc_encrypt']));
mcrypt_generic_deinit($crypto);
Most of them are good, a few of them are bad. Can anyone see anything I'm doing
wrong or a case I'm not covering? Thanks much.

[PHP] using BOTH GET and POST in the same page.
Dear All, I am reading PHP5 and MySQL Bible. Chapter 7 of the book says that PHP can use GET and POST in the SAME page! Also it says that we can use the SAME variables in GET and POST variable sets and that conflict resolution is done by variable_order option in php.ini Can some one write a small program to illustrate the previous ideas? It is not clear to me as to how to implement this. Many thanks, Ashim.
