| » Description | |
| PHP_Fork class. 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. [see basic example] 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. Requires PHP build with --enable-cli --with-pcntl --enable-shmop. Only runs on *NIX systems, because Windows lacks of the pcntl ext. @example browser_pool.php an interactive tool to perform multiple cuncurrent request over an URL. @example simple_controller.php shows how to attach a controller to started pseudo-threads. @example exec_methods.php shows a workaround to execute methods into the child process. @example passing_vars.php shows variable exchange between the parent process and started pseudo-threads. @example basic.php a basic example, only two pseudo-threads that increment a counter simultaneously. | |
