I want to use semaphore functions. The installation instructions reads
Support for this functions are not enabled by default. To enable System V semaphore support compile PHP with the option --enable-sysvsem . To enable the System V shared memory support compile PHP with the option --enable-sysvshm . To enable the System V messages support compile PHP with the option --enable-sysvmsg .
But I'm running XAMPP for Linux. Does this mean it's impossible for me to use semaphore functions? I'd also like to know exactly why one has to recompile all of PHP instead of, say, tweaking a php.ini setting or adding a new module.
