Example #1 eio_rename() example
<?php
$filename = dirname ( __FILE__ ). "/eio-temp-file.dat" ;
touch ( $filename );
$new_filename = dirname ( __FILE__ ). "/eio-temp-file-new.dat" ;
function my_rename_cb ( $data , $result ) {
global $filename , $new_filename ;
if ( $result == 0 && ! file_exists ( $filename ) && file_exists ( $new_filename )) {
@ unlink ( $new_filename );
echo "eio_rename_ok" ;
} else {
@ unlink ( $filename );
}
}
eio_rename ( $filename , $new_filename , EIO_PRI_DEFAULT , "my_rename_cb" , $filename );
eio_event_loop ();
?>
以上例程的输出类似于:
eio_rename_ok
