[PHP] Print a variable's name
I'd like to print a variable's name in a procedure along with it's value
Is there a way to do this?
for example:
---
function showvar($somevar) {
echo Now showing: . ... code to show var name . .\n;
echo Value: .$somevar;
}
$s1 = Hello World;
showvar($s1);
---
would produce:
---
Now showing: $s1
Value: Hello World
---
many thanks in advance...

Re: [PHP] Print a variable's name
Thanks Ryan,
but what I want is to be able to pass any variable to a procedure and
have the variable name and value printed by the procedure.
Can this be done?
I'm trying to extend my library of debugging functions/procedures by
having a procedure which can be used to inspect a variable whenever I
call it.
Thanks

Just escape it...
eg:
$ryan = something;
echo \$ryan =.$ryan;
that would print:
$ryan = something

Re: [PHP] Print a variable's name - FIXED
I didn't say SOLVED becuase this gets me sor of what I want :
I added to the function an optional parameter so that if I reall wanted
the var name to show I can pass it in...
I know it's messy, but for debugging it's fine:
function showvar($var,$varname=Var: ) {
echo Now Showing .$varname.: br\n;
echo $var;
}
This way I supply the var name if I want to.. such as:
$s1 = Hello World;
showvar($s1,s1);
or
showvar($s1);
thanks all
Ahbaid.

}
echo Variable Name: .$varname.br\n;
echo Variable Value: .$var.br\n;
}
showvar($test);
This is the only thing that works for me.I know it is messy

This is a bit kludgy, but should work:
function showvar($varname) {
if (!isset($GLOBALS[$varname])) { return; }
echo Now showing: $varname\n;
echo Value: .$GLOBALS[$varname].\n;
}
$s1 = Hello World;
showvar('s1');

Re: [PHP] Print a variable's name
That's the way I ended up going
pass the name and value along :)
Not what I was hoping for, but it gets the job done, and it's only for
debugging pruposes

Because PHP passes arguments by value, you will be out of luck in most
cases -- by the time your debugging function sees the argument, it's no
longer tied to the calling scope. Michael Sims' example function works
only for variables in the global scope, which probably won't work for
anything complex enough to need its own debugging library.

You may find what you need in debug_backtrace(). Alternatively, just pass
the variable name along:
function echo_var($varname, $varvalue) {
printf(%s: %s\n, $varname, $varvalue);
}
...Which isn't much of an improvement over a plain old echo/print. And if
that's good enough for Brian Kernighan, I'd hope it's good enough for you.

[PHP] Control Structure Syntax Question
Someone had posted a tip for using an abbreviated form of an if.. else
structure...
It looked something like:
$x : action1 : action2;
I'm trying to shorten having to do the following:
if ($x) {
action1;
} else {
action 2;
}
can someone please post the syntax if they know it? I am reading the
fine documentation but can't find it...
many thanks

[PHP] Weird Problem with INPUT tag
I'm building a site using PHP for the navigation section of each page and to to do the general page layout. To this effect I have created php functions to structure the pages and I fill in the static text specific to each page. This all works. I have now got to the point where I am doing a page to send emails... this uses a FORM with INPUT tags, what is weird is that under IE6 some of the INPUT fields are showing up with yellow backgrounds They all use the same style sheet class, and simply varying the spelling of the field name and label from emil to ail fixes it!!! for example the code below is coorrect (no yellowing): tr height=1 td class=labelEmil/td tdnbsp/td td colspan=2 input type=text name=emil size=80 class=finput /td /tr but the following code is yellowed: tr height=1 td class=labelEmail/td tdnbsp/td td colspan=2 input type=text name=email size=80 class=finput /td /tr Now this goes away under Mozilla or Firebird browsers, so I know that this is specific to IE6 I'd really like to know why this is happening and how to correct this behaviour, and I cannot tell my client to not use IE. thanks for all your help the link below shows the problem in action, note the Email and Emil sections http://geosysllc.ilmtech.com/contact many thanks, Ahbaid -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] PHP IDE?
My folding is setup to work based on a function to fold and unfold. I
have the function mapped to my spacebar, so pressing it while
in escape mode will either fold or unfold the code
Place this in your .vimrc and then you can use {{{ and }}} as your
start and end tags
if has(folding)
highlight Folded term=standout ctermfg=Yellow ctermbg=Blue
set commentstring=#%s
set fillchars=vert:|,fold:
set foldmethod=marker
set foldmarker={{{,}}}
fun! ToggleFold()
if foldlevel('.') == 0
normal! l
else
if foldclosed('.') 0
. foldclose
else
. foldopen
endif
endif
Clear status line
echo
endfun
Map this function to Space key.
noremap space :call ToggleFold()CR
endif
The reasons given about vim (or vi) being on platforms are exactly the
same that I have stuck with vim (vi) over the years.
In some shops they do not allow emacs on their boxes, some don't install
additional editors, but vi has always been a constant.
this is just my experience, so please note that I am not berating anyone
for their choice of editor...

Ahbaid.

Yeah .. vim is my god too. You can do so many things with so little

functions. I haven't doen so, but I know it's possible :P... Also, it exists
on most servers so you can work directly on the server. Without having to
mess with (Samba) filesharing. Another advantage is that it runs both on
Linux as well as on Windows.

(ps. Ahbaid or anyone else .. how can I get code to re-fold. I've setup my
vim to fold every PHP function and class, which works when I load te file.
But when I'm done editing a certain block, what do I do to make it fold back
in again?)

Re: [PHP] PHP IDE?
with folding you can fold your code in chunks, you basically setup a
start fold and an end fold and place code between them, then you can
open and close (fold) that block of code as you need to or don't need to
see it...
for example:
# {{{ PHP Code to do something...
..
..
1 lines of code...
..
..
# }}}
would collapse to one line when folded and look something like:
+ PHP Code to do something
then when you hit space on it it expands. (I use {{{ and }}} as my start
and end folds)
ctags allows you to build a dictionary of words which you can hook into
vim, that way you can do tab completion on PHP words etc.
I also like to map keystrokes to coding templates for things like
functions, loops, declarations etc.
Everyone's got their own setup :)
Plus I always use a CVS repository for my work, so my routine of, code,
test, commit is habit.
Looking at the responses there seems to be a lot of neat editors out
there, to each his own.
regards,
Ahbaid.

[PHP] PHP - Oracle - BLOBs - Display BLOB data in a table
I have written the first half of my application which stores images in BLOB fields of an oracle database. This part of my app. works fine. I am now trying to download the database stored blob and display it in my web page. I am able to get the blob data into a variable called $blobdata. If I just throw up a fresh page and issue the following code, the image displays fine: ?php Header( Content-type: $type); echo $blobdata; ? Assume that I have a function which when given an image id it returns the blob data as follows: $blobdata = get_image_data(2); // Get the blob data for image as stored in the database with id = 2 However, I would like to be able to place the blobdata say in a table cell as follows: tabletrtd ?php $blobdata = get_image_data(2); echo $blobdata; ? /td/tr only problem is that I am getting gobbledygook charcaters in the cell as the raw data is being printed, what sort of HTML or PHP functions should I use to do this? many thanks, Ahbaid. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] BLOB - PHP Peformance DB vs. Web server Opinions
Thanks to all who helped with my earlier questions on pulling BLOB data out of Oracle using PHP. I am however finding that performance is slow when downloading huge files from the database. A typical 2Meg GIF file being downloaded from Oracle via. PHP is taking about thirty seconds. Everything (database, web server, development box) are all on a 100 Megabit Switched ethernet setup. 1) Are there any pitfalls or guidelines when working with BLOBs and web apps? 2) Is there any advice for or against storing images as blobs in a database? Or is it better to store them on the web server file system? So far I am finding the web server file system to be faster, but I tend to think that it is less manageable from a relational data perspective. thoughts? thanks Ahbaid -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] date question
Hello all,
I would like to create a php function as follows:
function get_next_dates($ndays) {
/*
1. get the current date
2. create an array say $results
3. Store the dates for the next $ndays in $results
*/
return $results
}
So in my main program I can include the file with the function and use
it as follows:
?php
$next_4_dates = get_next_dates(4);
?
$next_4_days[0] - 11/20
$next_4_days[1] - 11/21
$next_4_days[2] - 11/22
$next_4_days[3] - 11/23
if today was 11/19
Is there an easy way to do this?
Can I somehow use something like getdate+7 say to get 7 days ahead?
many thanks,
