Can PHP Really Support Threading for Asynchronous Function Calls?

Asynchronous PHP Function Calls Using Threading

The challenge of executing PHP functions asynchronously can be overcome through threading, despite the common assumption that PHP lacks threading capabilities.

register_tick_function: A Threading Alternative?

The register_tick_function construct, often suggested as a threading solution, is not true threading. It operates within the same execution thread, merely invoking a callback function on specific time intervals.

PHP's Threading Capabilities

PHP does support threading through extensions such as pthreads and Thread. Using these, it's feasible to load data from databases like SQL and NoSQL in parallel.

Resources for Implementing PHP Threading

Refer to the PHP manual, GitHub examples, and PECL packages for guidance on implementing PHP threading.

Threading Installation

For PHP threading, install pthreads with a thread-safe PHP version, which is available from PECL (including Windows). Note that this is part of the PHP core, requiring no additional installations for thread-safety.
