More recently I have used cmalloc.i to allocate arrays of chars and
floats. The floats are happy, the chars crash upon allocation.
neat, swig generates php extensions. i wonder Eric, how much functionality
you intend to expose to php, a series of functions, classes? from the
sounds of your earlier description i would imagine maybe one class or a
single set of functions to operate on a single string variable, with
additional parameters for metadata.
im curious, if youre sold on the generator, or if youre interested to just
try your hand writing an extension. if youre strong w/ C you could probly
crank it out quickly. another option would be to version the generated
(swig) C, and repair it by hand, putting those changes in a branch. during
subsequent generations, you could merge the work from said branch and
iterate on that.
of course the other option is to figure out swig, lol. anyways, is this C
of yours for a private project or is it something i could take a peak at; im
halfway curious what youre working w/.
o, and guess what, reading through the swig php page, i discovered you can
write php extensions 'in c++', by creating a thin C wrapper - wow, i had
never thought of that, lol.

I will expose only one function, prototyped like the foo() example I described.
cstring.i is not implemented for a PHP target (wah).
I think I will go the shell approach. I have enough time in this already.

hi all,
i'm trying to write a wrapper function for mysqli_stmt_bind_results.
and expect it to work the same way it accepts and bind results to the
original function.
the problem is, i couldn't find a way to pass the args by reference
via func_get_args and register the out put from call_user_func_array
to the caller scope.. any idea?
here goes few lines which i'm trying hard for past 48 hours.. with no luck.. :(

great AJAX interface and good functionality.
I'm using it within a government context and they're really enjoying it.
I had a to make a few coding adjustments to facilitate a language
switcher between English and French as is normal in a Canadian context.
Additionally, due to the lack of folder hierarchy for documents (they
rely on the tagging system which is inefficient for our document
management) we are abusing the workspace system to provide the folder
hierarchy. This necessitated a hack to prevent the aggregated view of
all documents within sub-workspaces at parent workspace levels. If
you're using 1.5 btw, you should update to 1.6 ASAP since it corrects
some issues with inherited group permissions.

Hi,
I have the code as in the following, and I am trying to colorize the map. The
SVG File is located here:
http://upload.wikimedia.org/wikipedia/commons/5/5f/USA_Counties_with_FIPS_and_names.svg.
Looks like when I tried to modify the contents of the line, it does not seem
to take into affect. Thus, my map does not get colorized. Do I have to save the
file here? Or, is there something else I have missed here?
?php
//We are outputting an SVG

$array= array();
$array2= array();

[PHP] PHP programming strategy; lots of little include files, or a few big ones?
I have a flexible program, which can do many different things according to the type of data it is fed. Ideally the flexibility is achieved by calling different functions, though when the functionality is ill-defined I sometimes just include blocks of code. Ideally, from the point of program maintenance, each module should not be too long -- preferably just a page or so. This doesn't raise problems in a compiled language, but in an interpreted language like PHP the programmer must decide whether to lump a whole lot of functions into a single large include file, or to include lots of little files as the particular functions are needed. The first case can lead to memory bloat, as there are likely to be a lot of unused functions in memory on any given pass, whereas the second case may require lots of little files to be loaded. Are there likely to be significant performance costs for either approach, and what are your feelings about the relative virtues of the two approaches? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It is highly unlikely you are going to create any significant memory bloat. Your code will likely be infinitesimal compared PHP's memory requirement. I suggest 3 files, one with your configuration settings, so they are all in one place and easy to find and change, another file with your functions and the third file contains the code for handling the internet interface. Obviously, the interface file controls everything by calling various functions as needed. Al... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi, Just went online and saw an SVG generated from Python, and wanted to do the similar thing by loading the SVG into an PHP script. Here is the script that I have: ?php #Load the Map $ourFileName= USA_Counties_with_FIPS_and_names.svg; $fh = fopen($ourFileName, r) or die(Can't open file); fclose($fh); ? The problem is that my screen appears as blank even though I could open up USA_Counties_with_FIPS_and_names.svg and see the entire US Map. Does anyone know what I might have done wrong here?

Off the top of my head it sounds like something is being output before the header, which causes an error. If you also have error display turned off, you will likely just see a white screen with no useful information. Make sure none of your includes have trailing whitespace or are trying to print out information before the header itself. Best bet is to turn on errors and log them, then you will see where the output started if infact that is your issue.
