How to Extract JSONP Resultsets in PHP?

Extracting JSONP Resultset in PHP

PHP can retrieve data from JSONP URLs, even though JSONP returns a callback function. To do so, remove the function name and parentheses from the response and parse the remaining JSON using json_decode().

For convenience, a PHP function called jsonp_decode() can be used to streamline the process:

<code class="php">function jsonp_decode($jsonp, $assoc = false) { 
    if($jsonp[0] !== '[' &amp;&amp; $jsonp[0] !== '{') { 
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}</code>

Usage:

<code class="php">$data = jsonp_decode($response);</code>

This function simplifies the extraction of the JSONP resultset, making it accessible in a PHP variable.
