README
This PHP script detects the number of CPU cores available on a Linux server. It can be helpful for optimizing performance in multi-threaded applications by dynamically assessing hardware capabilities.
Purpose
This tool enables developers to retrieve the number of CPU cores on a Linux server using PHP. This is especially useful for performance optimizations and load balancing in server environments.
Features
- Detects the number of CPU cores on Linux-based systems.
- Utilizes shell commands (
hash
,nproc
,taskset
) to gather system information. - Lightweight and easy to integrate into existing PHP applications.
Supported OS/Programs
Currently supports Linux only, using the following utilities:
hash
nproc
taskset

Examples
Check out these examples to see the CPU core detection in action:
Async
$loop = Factory::create();
Detector::detectAsync($loop)->then(function ($result): void {
echo $result, \PHP_EOL;
for ($i = 0; $i < $result; $i++) {
Resolver::resolve($i, 'uptime')->then(function ($cmd): void {
echo $cmd, \PHP_EOL;
});
}
});
$loop->run();
Sync
$result = Detector::detect();
echo $result, \PHP_EOL;
for ($i = 0; $i < $result; $i++) {
Resolver::resolve((string)$i, 'uptime')->then(function ($cmd): void {
echo $cmd, \PHP_EOL;
});
}
