Global Variables
OWNET_GLOBAL_CACHE_STRUCTURE (array)
Class OWNet
(all read and set functions can return NULL if an error occur!)
OWNet($host='',$timeout=5,$use_swig_dir=true)
$host
host name with port OR uri
scheme://host:port (see function setHost for more
information about scheme)
scheme://host
host:port
host
anyother will get OWNET_DEFAULT_HOST and OWNET_DEFAULT_PORT
$timeout
the timeout when reading sockets and streams
$use_swig_dir
when getting dir we can output an array (use_swig_dir=false)
or an string with "," separator (use_swig_dir=true)
setTimeout($timeout=5)
$timeout
the timeout when reading sockets and streams
getTimeout()
return current timeout setted by setTimeout or OWNet
setUseSwigDir($use)
$use
use_swig_dir sting or array output when reading directory
getUseSwigDir()
return current use_swig_dir setted by setUseSwigDir or OWNet
setHost($host='')
$host
host name with port OR uri
scheme://host:port
scheme://host
host:port
host
$host will be parsed with parse_url() function
if no scheme was set in parse_url() array we will add an
default scheme "tcp://" and retry parse_url()
if no host was set in parse_url() we will use
OWNET_DEFAULT_HOST host
if no port was set in parse_url() we will use
OWNET_DEFAULT_PORT port
scheme "stream" and "ow-stream" are special schemes that
will force class to use streams functions instead socket functions
socket functions are faster and use less computer resources,
you will need extension socket loaded (with dl("socket.so") or
dl("socket.dll") or static compiled)
socket functions are used if
function_exists("socket_connect") return true and scheme != "stream" and
!="ow-stream"
getHost()
return an $host that can be used with setHost again
read($path,$parse_value=true)
$path
file to read from owserver
$parse_value
if true will return an parsed variable (string, bool or double)
if false will return always string variables
dir($path)
$path
directory to read files
if use_swig_dir is true will return an string with "," separator
if use_swig_dir is false will return an array with all files
ordered by owserver
presence($path)
$path
file to check presence
return true or false if presence ok
get($path='/',$get_type=OWNET_MSG_READ,$return_full_info_array=false,$parse_php_type=true)
MAIN FUNCTION FOR READ FROM OWSERVER
$path
file to read
$get_type
OWNET_MSG_* constant for each read function
$return_full_info_array
return information (for debugging) about owserver protocol
$pase_php_type
return an parsed variable (bool, string or double)
if false return always string
set($path,$value='')
$path
file to be write
$value
value to write
return true or false on error
Examples
EVERY FUNCTION TRIGGER AN ERROR! you should use @$ow->function to
don't handle errors
$ow=new OWNet("tcp://172.16.1.100:1234");
print_r($ow->dir("/"));
print_r($ow->read("/10.E8C1C9000800/temperature"));
print_r($ow->presence("/10.E8C1C9000800"));
print_r($ow->set("/10.E8C1C9000800/temphigh",35)); // any value will be
converted to string by fwrite function or socket_write
no problems setting ownet class variable to another type, no memory leak
present when unsetting without unset() function
$ow=false or
$ow=NULL or
$ow="" or
unset($ow)
