php - Running exec in a script -

-

i have this:

<?php if ($_get['run']) {   # code run if ?run=true set.   exec("./check_sample.sh"); } ?  <!-- link add ?run=true url, myfilename.php?run=true --> <button type="button" onclick="?run=true">click me!</button>

the shell script check_sample.sh has o/p prints using printf/echo when click 'click me' don't see o/p. anypointer on how make take text input , pass $1 arg. script help

exec() doesn't output anything. use passthru().

be very careful passing user input external program. if make sure escape using escapeshellarg().

kind of this:

passthru('./check_sample.sh '.escapeshellarg($your_user_input));
