[PHP] Problem solved!
I didn't want to give up entirely on the flexibility of writing my scripts in C, so I thought some more about how to get a CGI script to use PHP without having to spend a lot of time on PHP logic. My first attempt was to see whether I could substitute the extension .php for the usual .cgi extension. I could, but it made no difference, i.e., PHP didn't intercept the output. I did some searching in /usr/local/lib/php to no avail, but then I brought up the phpinfo page and studied it. Under the Environment heading, I found the variable SCRIPT_FILENAME and passed it a test PHP filename as a command-line argument. Voila! I got a HTTP header and the expected PHP-processed output! Now all I have to do is use popen from the C program that will become my CGI script, and I'll be able to let C handle the GET and/or POST query strings, create the MySQL queries, and pass a more manageable amount of PHP code to access the tables. Using HTTPS should also be more straightforward that way. I knew there had to be a better way! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] RE: How to make binary strings useful?
Here's the code (with the domain name removed)
that doesn't work, despite the poor documentation
of the variable types:
?
$dir = /home/domain_name/www/binary/;
$dh = opendir ($dir);
do
{
$file = readdir ($dh);
}
while (!strncmp ($file, ., 1));
$filename = sprintf (%s%s, $dir, $file);
$fh = fopen ($filename, r);
$cont = fread ($fh, 4);
echo file:BR;
echo $filename;
echo BRcont:BR;
printf (%02x %02x %02x %02x, $cont{0}, $cont{1}, $cont{2},
$cont{3});
fclose ($fh);
closedir ($dh);
?
Here's the output of od -c glance_date up to the fourth byte:
000 177 E L F
All four bytes are non-zero!

[PHP] How to make binary strings useful?
Is there an example of the UNIX od utility written
in PHP? Is such a useful task even possible??
From what I've seen of strings, they're completely
opaque, so what good does it do to be able to read
binary-safe strings from a file??? Even the deprecated
(why) $str{$inx} notation apparently results in
another string, because trying to printf it with the
%02x format always comes out with 00. (Maybe
that's why -- it's useless!) As an experienced C
programmer, I'm finding PHP to be as counter-intuitive
for low-level work as Perl is. I need to convert binary
dumps of data structures into database table rows, and
MySQL on my server doesn't support queries from C.
I thought about writing a CGI script (in C) that
would generate the hard-coded PHP output for
each instance, but a URL that ends in .cgi is
never intercepted by the PHP interpreter. Worse
yet, the SCRIPT LANGUAGE= SRC=
that works perfectly well with JavaScript is
likewise ignored if the language is PHP! Finally,
I'm not aware of a Content-type such as text/php.
What exactly was the purpose of designing yet
another inflexible language?!

There's a FAQ section entitled PHP and Other Languages, C isn't even listed among them! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] How to make binary strings useful?
That should help. Thanks.

I've written complete file parsers in PHP, and the only snag I've run
into is dealing Signed integers (and larger).

the pack() and unpack() functions are used to remove data from and
place data into binary strings.

$str{$inx} does return a single character string, in order to get the
numerical value, try using ord()
