Hi,
I have 2 main php questions and a few sub questions :-)
1.
I have Dreamweaver/EditPlus and Zend developer (some full versions some
trial) (am open to trying out other tools)
Is there anyway to do a find/replace on a particular variable in a whole
directory? (or all files that refer/use that variable)
eg:
find $GuessableVariable and replace it with $HardToGuessVariable
or do i have to go file by file and do a search?
2.
I have visited many sites which use ASP/JSP and PHP which instead of calling
*differient* pages like so:
http://somesite.com/pageName.php?s=blah
http://somesite.com/DifferientPageName.php?s=blah2
(thats the way i generally program)
keep calling the *same* page with numbers, like so:
http://somesite.com/pageName.php?s=333
then
http://somesite.com/pageName.php?s=334
http://somesite.com/pageName.php?s=253
etc
Whats the advantage of the above and whats the idea?
isnt it much easier (and logical) to keep track of pages if you give them a
logical name?
giving a page: loginClient.php is much easier than remembering
script.php?val=214
right?
Or am I missing something?
Thanks,

Hi ryan,
I have a search replace tool which i'll send to you, you can add all php
files to it and do a search replace on all of them at once, very simple.
and as for the 2nd question when I build sites I use the
index.php?page=contact etc type method, the point is to have one file
with your navigation/header/footer in so you can make one change to
these common parts for all pages.
e.g.
index.php?page=contact
would be as follows
*********
//header
//navigation
switch(page) {
case contact: include("contact.php"); break;
}
//footer
*********
whereas when you call a different file for each page it is more like this...
*********
include("header.php");
// code & content here
include("footer.php");
*********
or at least thats how I do it : )

G.Solomon

Sorry but thats not what i'm after. I want to know the available memory
needed to load the image. The default php memory limit is 8M and if the
image is large php is not able to load it because the 8M limit is
reached and therefore causes php to error out.
Is there a way to calculate the memory required to load the image
without haveing to load it? Would the following work...
$memSize = $imageWidth * $imageHeight * 4
This assumes that gd uses 32bits per pixel.

William Bailey.

Hi
I came across some strange session behaviour today using latest version of php
under apache 1.3.29 on redhat 9.
I am using a customer handler for the sessions, a simple mysql table. I am
finding that the session data intermitently switches to wddx serialisation
rather than the deault method. It appears to be random and I only noticed
when I ever so often I got SQL errors due to the single quotes in the WDDX.
There appeared to be no pattern to the behaviour. My php.ini file is set to
php not wddx and I have not used ini_set in my script to alter the default.
Has anyone seen anything similar?

OK. That worked, thanks.
Is it me, or is that rather odd behavior? Shouldn't array elements
set within a loop be available to me outside the loop if the loop
exits normally? A loop is not a function (well it is, sort of.)
Should I declare the variable as global?
global $content_array;
$city_found = 1;
while(!feof ...
When I was taking programming courses in college, I was taught that
breaking out of a loop like that was bad practice; that it was better
to leave a loop normally. I've never programmed in "C" other than to
write a crude little "dos2unix" (actually mac2dos) utility. Mosty
i've written Perl, PHP Pascal and Basic. Pascal, Perl and Basic
don't exhibit this behavior. I never worked with arrays in "C." Am
I wrong?

One common way to work around many search engines ignoring pages with
query strings is to use scripts with odd URIs
(http://server.com/foo.php/foo/bar for instance) and get them with
$_SERVER['PATH_INFO']. How compatible is doing that? Will servers
besides Apache support it?

How can I convert a string like this: "test & test" into
"test%20%26%20test" so I can then pass it to a script? Essentially
convert the spaces and & symbol to their ASCII HEX equivalent.

Duh, why didn't I think of urlencode() ?! I kept looking for
something with hex in it, or some string conversion. It never dawned on
me...I'm dealing with html stuff and conversion...and url never even
came to mind. Must be the turkey (more like, lack thereof...) Hay,

Working on a Macintosh G3 PowerBook running OS 10.2 and PHP 4.3.0 with GD2
...
I'm having trouble telling GD2 where the font I'm using in a PHP exercise
(Chapter 19 of the 2nd edition of the Welling/Thomson book), arial.ttf,
resides. The font is obviously in a folder on my hard drive, the path of
which runs like so:
Macintosh HD/Fonts/arial.ttf
The line of PHP code that gives this info goes like this--at least the way
I unsuccessfully put it:
putenv('GDFONTPATH=Macintosh HD/Fonts
$fontname = 'arial.ttf'
As I say, it doesn't work. Can anyone tell me how I should alter the code?
Should I put the font in the root folder, 'localhost/..."?
Thank you.
