| Wrapper around the pcntl_fork() stuff, with a API set like Java language. Practical usage is done by extending this class, and re-defining the run() method. This way PHP developers can enclose logic into a class that extends PHP_Fork, then execute the start() method that forks a child process. Communications with the forked process is ensured by using a Shared Memory Segment; by using a user-defined signal and this shared memory developers can access to child process methods that returns a serializable variable. The shared variable space can be accessed with the tho methods: o void setVariable($name, $value) o mixed getVariable($name) $name must be a valid PHP variable name; $value must be a variable or a serializable object. Resources (db connections, streams, etc.) cannot be serialized and so they're not correctly handled. Only runs on *NIX systems, because Windows lacks of the needed pcntl ext. |
