I have a php script that runs a python script. I have to compare python script's output with specific constants in php script. I tried using exec and popen. Here is the code I tried so far
$out=NULL;
$pid=exec("python /home/krishna/online/createProblems.py $contest $pcode $fn1 $fn2",$out) or die("error");
if ($out=="1"){echo "Successfully inserted problem";}
and using popen
$pid=popen("python /home/krishna/online/createProblems.py $contest $pcode $fn1 $fn2","r") or die("error");
$ot=fread($pid,256);
if ($ot=="1"){echo "Successfully inserted problem";}
Both codes are not working properly.... When I tested outputs I got "1" as output. but comparing with "1" is not working.
