- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.

Usage
Advanced usage
Changing the finders
When creating CpuCoreCounter, you may want to change the order of the finders
used or disable a specific finder. You can easily do so by passing the finders
you want
Choosing only logical or physical finders
FinderRegistry provides two helpful entries:
::getDefaultLogicalFinders(): gives an ordered list of finders that will look for the logical CPU cores count.::getDefaultPhysicalFinders(): gives an ordered list of finders that will look for the physical CPU cores count.
By default, when using CpuCoreCounter, it will use the logical finders since
it is more likely what you are looking for and is what is used by PHP source to
build the PHP binary.
Checks what finders find what on your system
You have three scrips available that provides insight about what the finders can find:
And:
Debug the results found
You have 3 methods available to help you find out what happened:
- If you are using the default configuration of finder registries, you can check the previous section which will provide plenty of information.
- If what you are interested in is how many CPU cores were found, you can use
the
CpuCoreCounter::trace()method. - If what you are interested in is how the calculation of CPU cores available
for parallelisation was done, you can inspect the values of
ParallelisationResultreturned byCpuCoreCounter::getAvailableForParallelisation().
Backward Compatibility Promise (BCP)
The policy is for the major part following the same as Symfony's one.
Note that the code marked as @private or @internal are excluded from the BCP.
The following elements are also excluded:
- The
diagnoseandexecutecommands: those are for debugging/inspection purposes only FinderRegistry::get*Finders(): new finders may be added or the order of finders changed at any time
