PHP Split string between several characters [duplicate]

Question

I have a script which records your WAN and LAN IP, but it also has a bunch of unnecessary characters around the printed answer. How can I split the IPs and get rid of these characters?

Printed Answer: {"ip":[["WANIP","LANIP"]]} What I want is 2 different variables, 1 to print wan and 1 to print lan.

I've tried with str_split and explode, maybe I didn't do it right or I can't do it with these, so any answers would help.

how are you getting these lan and wan address, is it from a json request ?? — Aman Virk

I'm actually getting it from someone else's server via @file_get_contents, so I'm unsure how the actual source code looks. — Dan

$json = '{"ip":[["WANIP","LANIP"]]}';
$decoded = json_decode($json, true); // true means it will format it into an assoc array

Then you'll be able to access your wanted strings by simply using $decoded['ip'][0][0] and $decoded['ip'][0][1] .

This did the trick, just had to change $json to return my the variable instead of that text, but worked in the end. Thanks!

It looks like your "printed answer" is JSON. In which case parse the json then extract the needed values.

You could use something like json_decode()

try this code:

$data = "{\"ip\":[[\"WANIP\",\"LANIP\"]]}";
$jdecode = json_decode($data,true);

echo $jdecode['ip'][0][0];
echo $jdecode['ip'][0][1];

Hope this helps :)

I would first strip out some of the unnecessary clutter, then explode:

$response =  '{"ip":[["WANIP","LANIP"]]}'; //or however you load your variable
$arryRemove = array('"', 'ip:[[', ']]}'); //specify an array of things to remove
$response = str_replace($arryRemove, "", $response);

$arryIPs = explode(",", $response);

$arryIPs[0] will contain WANIP, $arryIPs[1] will contain LANIP
