How can resource wastage be minimized when using exec() in PHP to call a program in the xterm?

When using exec() in PHP to call a program in the xterm, resource wastage can be minimized by properly managing the execution of the program and ensuring that it does not consume excessive resources. One way to achieve this is by setting resource limits using the setrlimit() function in PHP to restrict the amount of resources that the program can utilize. 

// Set resource limits for the program
setrlimit(RLIMIT_CPU, 10, 10); // Set CPU time limit to 10 seconds
setrlimit(RLIMIT_AS, 1000000, 1000000); // Set address space limit to 1 MB

// Call the program using exec()
exec('program_to_run', $output);

// Process the output as needed
foreach ($output as $line) {
    echo $line . "\n";
}
