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?
}

Answer 1

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

Answer 2

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){

}
