I am moving my web site to a new host this weekend. I am working
towards making the code compatible to the structure of the new server.
I am getting a weird response which I don't understand
At the very start of my index.php I have the following lines of code:
foreach($_GET as $key = $val) {
$$key = $_GET[$val];
echo $_GET[$val] . br /;
}
What I don't understand is why the output is
br /br /
I am not understanding how two empty variables are being passed.
index.php is driven off of various mod re-writes contained
within .htaccess . This is why I am doing the loop above.
RewriteRule ^page/([^/\.]+)/?$ index.php?page=$1 [L]
RewriteRule ^page/([^/\.]+)/([^/\.]+)/?$ index.php?page=$1field1=$2 [L]
RewriteRule ^page/([^/\.]+)/([^/\.]+)/([^/\.]+)/?$ index.php?page=
$1field1=$2field2=$3 [L]
What should I be trying? What will allow the value of page to be passed
onto $page with the following URL:

[PHP] Generate XHTML (HTML compatible) Code using DOMDocument
Hello,
After talking with Michael about how to generate XHTML code using the DOM I
came up with this little function that I'm thinking of using to generate XHTML
code that's HTML compatible:
function saveXHTML($dom) {
$html = $dom-saveXML(null,LIBXML_NOEMPTYTAG);
$html = str_replace('#13;','',$html);
$html = preg_replace('/\?xml[^]*\n/','',$html,1);
$html =
preg_replace('/\!\[CDATA\[(.*)\]\]\/script/s','//![CDATA[\1//]]/script',$html);
$html =
preg_replace('/\/(meta|link|base|basefont|param|img|br|hr|area|input)/','
/',$html);
return $html;
}

If this will maintain utf-8 I might be able to use it :) which
according to the last thread, saveHTML munges utf-8 stuff due to
libxml...
Hopefully this week I can give it a go.

Re: [PHP] extract varying data from array with different formatting

foreach does a nice job if you want the results identical each time.
What can you use to change the formatting of the results dependent on

your answer lies with not replacing foreach to make your life/output better. But with how the data is prepared and
handed off to the foreach statement.
I am guessing that what you want would be something like this.
Since this looks like a snippet of code I sent you the other day, I will snag it
complete from the other thread.
?php
...
# Test to see if the book has any authors
if ( isset($authors[$bookID]) ) {
# Tell us how many authors we found

# Add all the authors to that new array
$aList[] = {$authorData['last_name']},
{$authorData['first_name']};

$aList = array_map('htmlspecialchars', $aList);
# Get a count of how many authors their is.
$tAuthors = count($aList);

Use POST when you are submitting a form for storing info, using GET when you are retrieving from the server... GET can also be bookmarked and shared between computers without a problem... So depending on what your app is for that might be a consideration. POST does not display anything in the browser, so as others have said it's perfect for login's since that info will never be visible to the user. as far as REQUEST goes... I personally don't think it's any less secure then POST or GET... As long as you do sanitization on the info that is appropriate for your app, REQUEST is fine..

The best description of when to use what, is this.. Use POST when you are submitting a form for storing info, using GET when you are retrieving from the server... I always use post unless the situation makes post impractical. Example - with search results, you may have more than one page of results. The only practical way I have found to have the nice numbered links to other pages of a search result sent via post is to use JavaScript. Many users (myself included) are hesitant to enable JavaScript on sites we do not trust, especially search engines, as search engines often are vulnerable to xss (usually reflected but not always). With get in that scenario, you just create a hyperlink with the variables, no need for javascript. But for most scenarios, if I can do it with post I really prefer to, especially since many of my forms have an ugly 32 character long post token (for csrf protection). It's too bad that browsers don't have an option that can be set by a html parameter for hiding get values from display in the url bar, they really are ugly to look at and the user shouldn't have to see them unless they are cutting and pasting a link. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

foreach does a nice job if you want the results identical each time.
What can you use to change the formatting of the results dependent on
the number of results.
Here's an example:
foreach ( $authors[$bookID] AS $authorID = $authorData ) {
# Display the
echo {$authorData['first_name']}
{$authorData['last_name']}\n;
}
will echo - Joe Boe John Blue Andy Candy etc depending on how many rows
we have.
What I want is: Joe Boe, John Blue, Andy Candy Hans Stick ( separated
by commas, except for the last one which is separated with .
I thought of passing a variable to the foreach and then using if
elseif... but that can't work because the variable is reset to 0 after
each pass.
Can't get switch to do it (maybe I don't understand it right.
Help ?

[PHP] What was the unix timestamp of last week, Monday 12:00 am?
I'm trying to write a [simple] function, such that:
function earlier_unix_timestamp () {
$now = mktime();
[...]
return $then; // e.g., 1238983107
}
Anyone have something already made? There seem to be many ways to skin

first day of the month, etc.) are driving me crazy.

Having a Not Null with no default is bad db design. I need it to error when an attempt to create a record without setting that field is attempted, but setting the field to an empty string is fine. Attempting to insert data without defining that field indicates there is not sufficient information to create a record. Setting that field to a zero length string however indicates that there is enough information to create a record. Assuming that no information is the same as an zero length string is not OK. Call it bad design if you want, by MySQL knows the difference between NULL and an empty string, so should my database abstraction layer. Even if the default is set to '' - pear mdb2 refuses to do the insert. So it looks like pear mdb2 does not know the difference between NULL and a zero length string.

RE: [PHP] what to use instead of foreach
You may try something basic like:
$b = 1;
foreach ($my_array as $a)
{
echo $a ;
//Send new line to browser
if ($b++ == 3) { echo br; $b = 1; }
}
Or there are some different ways to approach this also like:
for ($a = current($my_array); $a; $a = next($my_array))
{
//Format 1
echo $a ;
$a = next($my_array);
//Format 2
/* you may add checks here to see if $a contains data */
echo ~ $a ~ ; $a = next($my_array);
//Format 3 + NEW LINE
/* you may add checks here to see if $a contains data */
echo ~~ $a ~~br ;
}
This way you have some added control over the iteration through the array,
and you can play around with when how to display what.
Regards.

Subject: [PHP] what to use instead of foreach
foreach does not allow for different formatting for output...
What could be used as a workaround?
example:
echo $some_result, br; // will print all results in 1 column
echo $some_result, ,; // will print all results comma-separated in 1 row
But how do you get result1, result2 result3 // with br at end ?

Re: [PHP] Connecting to dBase using ODBC on Mac OS X
I know this isn't exactly what you were probably looking for but... If you have a Windows machine available I would recommend taking a look at the ODBTP project at http://odbtp.sourceforge.net. ODBTP stands for Open DataBase Transport Protocol. The short version is that you add a client module to PHP which allows you to connect to a server on the windows machine. Using this client/server you can connect to any ODBC source on the windows machine from the Mac. I know it's not perfect (since you need Windows running) but we've used it to add Web acessibility to a legacy VFP app with some success. Caveat: These are, all things considered, relatively small installations. By small I mean 5-100 users per intranet accessing 100-20,000 customer records. I could not imagine using this solution for any major, publicly accessible web site. (We have one client that tracks 300,000+ records and performance is NOTICABLY slow) Pro: Allows you to access any odbc compliant database from any web server that you can compile the client for. Con: Requires Windows (works reasonably well with a Parallels installation though...) Only as stable as the underlying ODBC driver (the VFP driver is single threaded and locks up after a while... but restarting the ODBTP service frees it all up.) Overall: Good for transitioning from a Legacy application or for infrequent tasks like importing from windows only file formats (like VFP). We've used this in several installations where the client doesn't want to lose their legacy app, refuses to upgrade and wants to provide web access to sales people on the road. We've seen the best performance using PHP under IIS on Windows connecting to the same machine. Our worst case for performance is an installation that uses a Mac OSX 10.4 XServe Web Server connecting to a Windows 2003 Server which then accesses VFP data files on a Novell Server of some flavor. (From that client I learned that apparently Windows ALWAYS tries the Microsoft network file redirectors before it will try any available Novell network file redirectors. At least that's what the Client's IT department tells me whenever we relay user complaints about the speed at that site) Hope this helps. Matt On Thu, Apr 9, 2009 at 10:53 AM, Rahul S.
