fidry / cpu-core-counter example snippets


use Fidry\CpuCoreCounter\CpuCoreCounter;
use Fidry\CpuCoreCounter\NumberOfCpuCoreNotFound;
use Fidry\CpuCoreCounter\Finder\DummyCpuCoreFinder;

$counter = new CpuCoreCounter();

// For knowing the number of cores you can use for launching parallel processes:
$counter->getAvailableForParallelisation()->availableCpus;

// Get the number of CPU cores (by default it will use the logical cores count):
try {
    $counter->getCount();   // e.g. 8
} catch (NumberOfCpuCoreNotFound) {
    return 1;   // Fallback value
}

// An alternative form where we not want to catch the exception:

$counter = new CpuCoreCounter([
    ...CpuCoreCounter::getDefaultFinders(),
    new DummyCpuCoreFinder(1),  // Fallback value
]);

// A type-safe alternative form:
$counter->getCountWithFallback(1);

// Note that the result is memoized.
$counter->getCount();   // e.g. 8



// Remove WindowsWmicFinder 
$finders = array_filter(
    CpuCoreCounter::getDefaultFinders(),
    static fn (CpuCoreFinder $finder) => !($finder instanceof WindowsWmicFinder)
);

$cores = (new CpuCoreCounter($finders))->getCount();


// Use CPUInfo first & don't use Nproc
$finders = [
    new CpuInfoFinder(),
    new WindowsWmicFinder(),
    new HwLogicalFinder(),
];

$cores = (new CpuCoreCounter($finders))->getCount();
