Examples
Example #1 eio_lstat() example
<?php// Create temporary file$tmp_filename = dirname(__FILE__) ."/eio-file.tmp";touch($tmp_filename);/* Is called when eio_fstat() done */function my_res_cb($data, $result) { // Should output array with stat info var_dump($result); if ($data['fd']) { // Close temporary file eio_close($data['fd']); eio_event_loop(); } // Remove temporary file @unlink($data['file']);}/* Is called when eio_open() done */function my_open_cb($data, $result) { // Prepare data for callback $d = array( 'fd' => $result, 'file'=> $data ); // Request stat info eio_fstat($result, EIO_PRI_DEFAULT, "my_res_cb", $d); // Process request(s) eio_event_loop();}// Open temporary fileeio_open($tmp_filename, EIO_O_RDONLY, NULL, EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);eio_event_loop();?>
The above example will output something similar to:
array(12) { ["st_dev"]=> int(2050) ["st_ino"]=> int(2489159) ["st_mode"]=> int(33188) ["st_nlink"]=> int(1) ["st_uid"]=> int(1000) ["st_gid"]=> int(100) ["st_rdev"]=> int(0) ["st_blksize"]=> int(4096) ["st_blocks"]=> int(0) ["st_atime"]=> int(1318239506) ["st_mtime"]=> int(1318239506) ["st_ctime"]=> int(1318239506) }
