Req #62799 [Opn->Sus]: Parallel array processing

Edit report at https://bugs.php.net/bug.php?id=62799&edit=1 ID: 62799 Updated by: cmb@php.net Reported by: info at ludwig-gramberg dot de Summary: Parallel array processing -Status: Open +Status: Suspended Type: Feature/Change Request Package: Arrays related Operating System: Any PHP Version: Irrelevant Block user comment: N Private report: N New Comment: This is unlikely to happen for NTS builds. For ZTS builds you can use the parallel extension[1] to build such functions in userland. Anyhow, if you want to see this feature in php-src, please pursue the RFC process[2]. For the time being, I'm suspending this ticket.

Example: <?php $arr = array(1, 2, 3, 4); array_process_parallel($arr, function($a) { return $a+5; }); ?> Now $arr would contain the following: [6, 7, 8, 9]. The values are written back to $arr. The parameter is called by reference. Also a array_parallel_reduce would be nice. Test script: --------------- $arr = array(1, 2, 3, 4); array_process_parallel($arr, function($a) { return $a+5; }); Expected result: ---------------- [6, 7, 8, 9] ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62799&edit=1
