I am writing a PHP script that executes shell commands on a linux machine. When I run this script on Linux system, it waits while it executes the command and store the result in a PHP variable. But when I run it on a web browser, the browser don't wait to get result of the command execution and moves on. I want that browser to wait 2 seconds while it executes that command. How can I do this. Please help me.
The PHP Code is as under:-
<html> <body> <?php $cpu=exec('top -d 1 -n 1|grep Cpu | tail -n 1 | cut -c 25-33'); echo "The Current CPU Utilization is ".$cpu; <?php $mem=exec('top -n 1|grep Mem'); echo $mem; ?> </body> </html>
