Your tcl script should write on stdout:
set a 10
set b 20
set c [expr {$a + $b}]
puts $c
If your tcl script is supposed to output multiple lines:
eg:
puts $c
puts $c
puts $c
you can capture them in a PHP array:
eg:
$array = array();
function print_procedure ($arg) {
echo exec("/opt/tcl8.5/bin/tclsh test.tcl",$array);
//print_r($array);
}
