Parameters

Examples
Example #1 eio_statvfs() example
<?php
$tmp_filename = '/tmp/eio-file.tmp';
touch($tmp_filename
function my_statvfs_callback($data, $result) {
var_dump($data
var_dump($result
@unlink($data
}
eio_statvfs($tmp_filename, EIO_PRI_DEFAULT, "my_statvfs_callback", $tmp_filename
eio_event_loop(
?>
The above example will output something similar to:
string(17) "/tmp/eio-file.tmp"
array(11) {
["f_bsize"]=>
int(4096)
["f_frsize"]=>
int(4096)
["f_blocks"]=>
int(262144)
["f_bfree"]=>
int(262111)
["f_bavail"]=>
int(262111)
["f_files"]=>
int(1540815)
["f_ffree"]=>
int(1540743)
["f_favail"]=>
int(1540743)
["f_fsid"]=>
int(0)
["f_flag"]=>
int(4102)
["f_namemax"]=>
int(255)
}
