How to parse JSON in PHP

Question

I'm trying to parse JSON sent by POST to my webservice. I'm using Advanced Rest Client tool for Google Chrome to test restapi.

How can I read this request and response to it?

I'm sending key called "format" and "json" as value for this key. I'm adding JSON like

"{"id":"235325"}"

Part of my PHP API code:

if( strcasecmp($format,'json') == 0 )
{
   //how to read that id = 235325?
}

but how? I'using Google Chrome plugin called Advanced Rest Client. And i'am waiting for response. i dont kwno how to attach this json: "{"id":"235325"}" to link: 78.28.23.180/index2.php?format=json on webbrowser — kmathew

the plugin may not support post data, use curl from your application and post data a to file expecting post. return the result. — mdamia

Try the json_decode() function. It is the standard function to parse json in php.

Would it help the OP, and other viewers of your answer, to explain why this function applies to this problem? And a visit to the manual will be worthwhile?

If want to work with array:

$json = '{"id":"235325"}';

$array = json_decode($json, true);

foreach($array as $element){
if($element == 0){

}
}

With object:

$json = '{"id":"235325"}';

$object = json_decode($json);

if($object->id == 0){

}
