Extension EIO.

This is a PHP extension wrapping functions of the libeio library written by Marc Lehmann.

Libeio is a an asynchronous I/O library. Features basically include asynchronous versions of POSIX API(read, write, open, close, stat, unlink, fdatasync, mknod, readdir etc.); sendfile (native on Solaris, Linux, HP-UX, FreeBSD); readahead. libeio itself emulates the system calls, if they are not available on specific(UNIX-like) platform.

<?php
$str      = str_repeat('1', 20);
$filename = '/tmp/tmp_file' .uniqid();
@unlink($filename);
touch($filename);
eio_open($filename, EIO_O_RDWR, NULL, EIO_PRI_DEFAULT, function($filename, $fd) use ($str) {
     eio_write($fd, $str, strlen($str), 0, null, function($fd, $written) use ($str, $filename) {
             var_dump([
                     'written'  => $written,
                     'strlen'   => strlen($str),
                     'filesize' => filesize($filename),
                     'count'    => substr_count(file_get_contents($filename), '1')
                     ]);
     }, $fd);
}, $filename);
eio_event_loop();
