Fine, just switch the order you are adding them to the two different arrays.
instead of this:
$find[] = '$pay_rate';
$find[] = '$pay_rate_bap';
$replace[] = $pay_rate;
$replace[] = $pay_rate_bap;
do this
$find[] = '$pay_rate_bap';

have the same problem as I did with str_replace... As long as the variable

If I read the manual correct about how to setup the input
values for str_replace()
you should be able to do the following.
This is completely untested, since I have now system like
yours. But here is goes...
#setup the entries that you want to find.
$find[] = '$name';
$find[] = '$ppe';
#setup the values to be replaced.
#Mind you to keep the indexes the in sync with $find...
$replace[] = $name;
$replace[] = $ppe;
echo 'pre';
while ( $row = mysql_fetch_assoc($resultHandle) ) {
$row = str_replace($find, $replace, $row);
// do something with $row. Display it maybe...
var_dump($row);
}
echo '/pre';
Basically replace $find[0] with $replace[0] in any of the
values of the return $row then replace the
previous $row values with the newly modified values...
Then go to the next index of $find[1] and
$replace[1] and do the same thing until you are out of indexes.
But this is a much better way of doing this than using
eval(). eval is an evil little function!

Re: [PHP] tabbed navegation PHP
Dwayne Heronimo wrote:
Dear All,
I have made a tabbed navegation with CSS. And if you set class=active to
one of the tabs, it will then be highlighted.
So I thought to make this dymamic with PHP. Using the $_GET variable I can
get the page name above with something like. $page_name = $_GET['page'] ;
so I can tell the class when to be active to what page.
Should I use the isset function for this? I am very new to PHP but here is
my try, but of course its not working:
?php
if (isset ($_GET['page'])) {
$page_name = $_GET['page'] ;
if ($page_name = default) {
$flg_page_default=1;
}
if ($page_name = about) {
$flg_page_about=1;
}
}
?
a ?php if(!isset($flg_page_default)) echo 'class=active'; else echo '';
? href=index.php?page=defaultspanhome/span/a
a ?php if(!isset($flg_page_about)) echo 'class=active'; else echo ''; ?
href=index.php?page=defaultspanabout/span/a
Of should I stick to just static html :(
Dwayne
Close, but this is probably how you should do it
$links = array();
url display
$links['default'] = Home;
$links['about'] = About;
etc...
foreach($links AS $url = $text) {
$class = '';
if ( isset($_GET['page']) $_GET['page'] == $url ) {
$class = ' class=active';
}
echo a href='index.php?page={$url}'{$class}span{$text}/span/a\n;
}
This will allow you to change one piece of code, instead of twenty lines later
on.
Use a little of the DRY principle.

So there's no PDO experts out there, eh? :-( On Wednesday 28 March 2007 11:14 pm, Larry Garfield wrote: HI all. The PHP.net manual is somewhat unclear on this point, so I thought I'd ask here. Does PDO automatically buffer queries the way that the mysql_* extension does, in order to allow multiple result sets open at the same time? Or is that something that has to be set on the connection, and if so, is that available for all drivers? I ask because I am running into a problem with a query segfaulting on me, but only under PHP 5.1 with PDO from pecl. It ran fine in PHP 5.2.0. The only mention in the manual on this subject is: http://us2.php.net/manual/en/ref.pdo-mysql.php If this attribute is set to TRUE on a PDOStatement, the MySQL driver will use the buffered versions of the MySQL API. If you're writing portable code, you should use PDOStatement::fetchAll() instead. The sample code there suggests that nothing does buffered queries except the MySQL driver. I find no mention of that anywhere else, though, one way or another. Of course, using fetchAll(), as it suggests, means that I only get arrays, not objects. (Unless I'm misreading those docs, too.)

[PHP] Security Best Practice: typecast?
So, after a recent thread on data filtering, I'm wondering... Is this good enough in ALL possible Unicode/charset situations: $foo_id = (int) $_POST['foo_id']; $query = insert into whatever(foo_id) values($foo_id); Or is it possible, even theoretically possible, for a sequence of: [-]?[0-9]+ to somehow run afoul of ANY charset? Perhaps more interesting, how about this: $foo = (float) $_POST['foo']; Is there any way for any PHP output from (float), even with decimal overflow/underflow in various databases, for that to go wrong? Should one be ultra-conservative and just do: $foo_sql = mysql_real_escape_string($connection); or is that just being silly? -- Some people have a gift link here. Know what I want?

Oracle also needs environment variables which are not present in a

You typically need to do something not unlike:
PutEnv('ORACLE_HOME=/path/to/oracle/home');
I forget the exact syntax, and there well may be other variables
Oracle needs.
The fancy POWL thing (whatever it is) probably has settings in its

The apache first part is, I think, that you need the Apache headers and configure scripts from Apache's ./configure (and maybe make) for PHP to be able to find them. And FrontPage extensions, if you want those, first, because they change Apache headers, and PHP won't work if it isn't working with the changed headers. This is for sure with Apache and PHP as Module. Whether it's needed for FCGI is beyond my ken. As far as the Apache config lines for FCGI, I should think the Apache manual would have that laid out pretty well. http://apache.org/ They've got very very good docs there, once you figure out their organizational schema for docs, which is pretty clear. -- Some people have a gift link here.

If I read the manual correct about how to setup the input
values for str_replace()
you should be able to do the following.
This is completely untested, since I have now system like
yours. But here is goes...
#setup the entries that you want to find.
$find[] = '$name';
$find[] = '$ppe';
#setup the values to be replaced.
#Mind you to keep the indexes the in sync with $find...
$replace[] = $name;
$replace[] = $ppe;
echo 'pre';
while ( $row = mysql_fetch_assoc($resultHandle) ) {
$row = str_replace($find, $replace, $row);
// do something with $row. Display it maybe...
var_dump($row);
}
echo '/pre';
Basically replace $find[0] with $replace[0] in any of the
values of the return $row then replace the
previous $row values with the newly modified values...
Then go to the next index of $find[1] and
$replace[1] and do the same thing until you are out of indexes.
But this is a much better way of doing this than using
eval(). eval is an evil little function!

This is all JS, obviously...
What are the technologies IF there are any and what should i look up
to find
docs that cover this type of datatransfer ie: javascript-php.
So now in the PHP part, to force this at least nominally on-topic, you
have a nice array in $_POST['styles'] with an index by div in order,
that you'd process like any $_POST value which is an array:
if (isset($_POST['styles']) is_array($_POST['styles'])){
foreach($_POST['styles'] as $d = $style){
//do something with div's $style, indexed by $d
}
}
You could presumably get each div's id with div.id or somesuch, and
use that instead of 'd' above.

One can even store up to 4K of session data *in* the cookie, sufficiently encrypted with a 2-way encryption with the private key server-side, and achieve server-neutrality in a server farm, if one is so inclined. So it's POSSIBLE for one to architect a system wherein the session all lives on the client. If you're willing to expose your entire inner workings of your application (e.g., it's Open Source anyway, or there's just nothing worth hiding in the first place) you wouldn't NEED to encrypt the data. None of this would be useful in the context of this particular thread. [/pedantic] -- Some people have a gift link here. Know what I want?

Re: [PHP] tabbed navegation PHP
You've not quite caught the trick of the difference between == and =
if ($page_name = 'default')
does not TEST $page_name -- It changes it, and then returns the new
value.
So, pretty much, your $page_name will ALWAYS be 'default' after you
hit this line, no matter what it started out as.
When in doubt about a script, toss in some:
echo $page_name;
statements here and there, to see if the variables are what you think
they are.
This usually lets you narrow down pretty quickly where things are
wrong, and then the why part is usually fairly simple.
... Though I confess I just blew half a day figuring out that:
script type=text/javascrpt
was not right. :-(
[note spelling]
Must have read that line 100 times in the course of the day, trying to
figure out why the alert('hello'); right after it wasn't working. :-(
Firefox, Firebug, HTMLValidator...
Not one of them bothered to tell me unknown type :-(

Dear All,
I have made a tabbed navegation with CSS. And if you set
class=active to
one of the tabs, it will then be highlighted.
So I thought to make this dymamic with PHP. Using the $_GET variable I
can
get the page name above with something like. $page_name =
$_GET['page'] ;
so I can tell the class when to be active to what page.
Should I use the isset function for this? I am very new to PHP but
here is
my try, but of course its not working:
?php
if (isset ($_GET['page'])) {
$page_name = $_GET['page'] ;
if ($page_name = default) {
$flg_page_default=1;
}
if ($page_name = about) {
$flg_page_about=1;
}
}
?
a ?php if(!isset($flg_page_default)) echo 'class=active'; else
echo '';
? href=index.php?page=defaultspanhome/span/a
a ?php if(!isset($flg_page_about)) echo 'class=active'; else echo
''; ?
href=index.php?page=defaultspanabout/span/a
Of should I stick to just static html :(

actually I don't know what the problem is, but I would do it in a much

You really ought to be filtering the $_GET data here...
http://example.com/categories.php?pagename=/etc/passwd
will pretty much blindly dump out a file you should not be exposing.
Also, as a matter of style:
$pagename is just kinda silly...
It takes a string and embeds it into a string with, err, nothing else,
and so you end up with the same string, only making PHP do extra
work to get there.
Actually, I suppose PHP might be smart enough to optimize this away...
But it looks silly, on the surface at least.

Re: [PHP] Alternative/Addition to using a CAPTCHA
On Thu, March 29, 2007 7:33 pm, John Comerford wrote: I was reading the current tread on CAPTCHA and possible cracks and I thought maybe I'd throw this out to the group to see what you think. Recently I saw a forum where in order to post you first had to click on a div that was placed at a random location on the page, it read something like, Click here if you are human. I was thinking that maybe you could put together a system that looks something like this: http://people.aapt.net.au/JComerford/ClickMe.htm I was thinking you could use it in a couple of ways: 1) As a replacement to a CAPTCHA image 2) When you click the image a CAPTCHA image is loaded into the 'Click Me' container The main problem is how to tell the server that the div has been clicked, in a way that can't be simulated. I am not an expect with either JS or PHP, but maybe some of the bigger brains out there could throw in their 2 cents.. Clicking on it in JS would be pretty trivial with webmonkey, I should think. Even if it wasn't, and you made it an image and only stored the correct pixels server-side, you're still subject to the same kind of AI Vision / OCR type of thing that a traditional CAPTCHA is subject to, really. Virtually *any* barrier you toss up will stop the brunt of the stoopid spambots. Even the Chris Shifflet method (see his blog) probably gets rid of all the junk. NO barrier will stop a dedicated human-architected attack. The better CAPTCHAs are almost as hard for humans as they are for the scripts designed to beat them -- Not really a win as they hurt usability too much. I would suggest using the method least likely to hurt your usability/accessibility, and easiest to implement. Unless you have somebody out there who is out to get you, it will work. If there IS somebody out to get you, nothing will work anyway. -- Some people have a gift link here. Know what I want?

Re: [PHP] Gnome and MIME types
exec takes a couple optional args to get your error code and output. Use them. Then use perror on the command line to see what error code means. Or I guess you could install my perror extension, if you were bored: http://l-i-e.com/perror All that said, I'm not at all sure why you are trying to do what you are doing, so can't really guess the best way to do it. Where do the files come from? Why do you want to guess their mime type? PHP can't do much useful with a mime type of an MS Office Document anyway... Unless you are running PHP on Windows, and want to use http://php.net/com to open up the document...

I then tried running system(file -i -m /usr/share/docs/mim file) which worked, but file doens't provide very good mime types -- all Microsoft Office Documents returned nothing, for example. I then stumbled upon gnomevfs-info that provided the information I wanted. I don't know what mime database it is using (couldn't find it) but it sure seemed more complete than anything else I had used. Problem is, I can't seem to run it from within a PHP script (system, exec, etc). I used the full path (/usr/bin/gnamevfs-info) so I don't believe that to be the problem, and the page has no errors (I am using error_reporting(E_ALL)). Any tips or suggestions? Thanks!
