execute C programs with PHP

[aisman]

hi everyone,

i can't execute an extern program compiled in Unix OS from php. I want to execute an C executable with params but the EXEC function return false always. A note: i have permissions for execute in Unix. this is my source:

//Previously i have to connect to Unix count correctly
$dir=chdir("scripts");

$handle=opendir('.');

  echo "Directory handle: $handle\n";

  echo "Files:\n";

  while ($file = readdir($handle)) {

   echo "$file\n";

   }

$meic=exec("make",$q1,$q2);//This is correct

//The wrong exec:
$coman="copies [c] nina.txt eurocaixer.c 13035_12960.c";//Copies is the executable and [c] nina.txt etc are params
//Exec Coman:
$executat=exec($coman,$a1,$a2);

🙂

Couple things to try, I know you said you had permission to execute but does that mean that apache (or whatever user acutaully runs the script in PHP) has execute permissions?

Maybe echo the output of passthru() function instead of exec()?

The other option (if you don't need to get any feedback) is just to backtick it--sloppy, I know...but it does usually work
