RE: [PHP] Passing an array to a C program from a php script??
Here is a solution I've found for my problem. I use join to convert my array
into a string. Then, I use exec to run the c program, having a pipe passing
the result from an echo. I would like to know if this solution is a good
one (in term of speed, security...), and would appreciate your comments.
Thanks.
Nicolas
Here is a short example :
// Initialize the array
$ary_test = array(15, 150, 32, 46, 69, 40, 22);
// Convert it to a string
$str_test = join(' ', $ary_test);
// Execute the c program
exec("echo \"$str_test\" | test1", $ary_result, $num_return);
// Display the return value and the result of the program
echo "Return value : $num_return\n";
echo "Result :\n";
print_r($ary_result);

Objet : [PHP] Passing an array to a C program from a php script??
Hi all,
I have a big array (nearly 1000 lines) that I would like to pass to a C
program. I don't want to create a temporary file to pass my array (If
possible ?!?), and I don't think the command line will fit my needs.
Is there a way to execute a program with a php string as the standard
input. Something like shell redirection 'c_program < input.file' but with
input.file being a php variable and not a real file ?? Any other solution
??
Hope I am clear enough !
Any help would be appreciated.
Nicolas

Any other solution > ?? 2 choices: #1 (for the real hacker geek) Compile your C program *into* PHP as a function, using the PEAR stuff. You may need to use PHP's http://php.net/serialize function to turn your array into a giant string and write a C routine to unserialize it, or, by the time you get done converting your program to PEAR, it will just accept your PHP array as an argument. #2 (pretty slick, though...) Run your C program using http://php.net/psockopen and use http://php.net/fputs to spew your data at it one line at a time. -- WARNING [EMAIL PROTECTED] address is an endangered species -- Use [EMAIL PROTECTED] Wanna help me out?

If your PHP script outputs to stdout, then you could run: c_program < myscript.php Your PHP script will need to output the array as if it were outputting to the screen or web page (ie, echo/print), and your C program will need to know what format it's coming in as.

Why not make a separate .txt file which is read by the PHP script to make its variable with file(), and have the C file read it with ifstream to make up its variable? --Jason -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
