Example #1 Grouping requests

<?php
/*
 * Create a group request to open, read and close a file
 */

// Create temporary file and write some bytes to it
$temp_filename dirname(__FILE__) ."/eio-file.tmp";
$fp fopen($temp_filename"w");
fwrite($fp"some data");
fclose($fp);

/* Is called when the group requests are done */
function my_grp_done($data$result) {
 
var_dump($result == 0);
 @
unlink($data);
}

/* Is called when eio_open() done */
function my_grp_file_opened_callback($data$result) {
 global 
$grp;

 
// $result should contain the file descriptor
 
var_dump($result 0);

 
// Create eio_read() request and add it to the group
 // Pass file descriptor to the callback
 
$req eio_read($result40,
   
EIO_PRI_DEFAULT"my_grp_file_read_callback"$result);
 
eio_grp_add($grp$req);
}

/* Is called when eio_read() done */
function my_grp_file_read_callback($data$result) {
 global 
$grp;

 
// Read bytes
 
var_dump($result);

 
// Create eio_close() request and add it to the group
 // $data should contain the file descriptor
 
$req eio_close($data);
 
eio_grp_add($grp$req);
}

// Create request group
$grp eio_grp("my_grp_done"$temp_filename);
var_dump($grp);

// Create eio_open() request and add it to the group
$req eio_open($temp_filenameEIO_O_RDWR EIO_O_APPEND NULL,
  
EIO_PRI_DEFAULT"my_grp_file_opened_callback"NULL);
eio_grp_add($grp$req);

// Process requests
eio_event_loop();
?>

The above example will output something similar to:

 resource(6) of type (EIO Group Descriptor) bool(true) string(4) "some" bool(true)
