integrating c in php, scanf and printf

[vks_foe]

Hi friends,

 

i have an executable made from c code which i call in my php script using exec. The code uses scanf to get input from stdin. But when call this from my webpage, the scanf part is ignored and some junk values are assumed. Is there any means to provide runtime inputs/values to the executable, when called using exec, system, etc in phpscript??

You could try something like:

 

exec("echo 'what ever you want to stdin' | /path/to/bin/prog");

If not, proc_open() should do it but will take some study.

Oh, and scanf() probably needs a newline, so:

 

exec("echo -e 'what ever you want to stdin\n' | /path/to/bin/prog");
