Accessing Swift Code IFSC Codes API, Php Script Error

Question

I am trying to access swift codes, ifsc codes, micr codes data from this free API, they have given this sample php code to access the data in JSON format.

unction get_ifsc_code($url, $curl = true) { $responseString = ''; if (!$curl) { /* * if !$curl, use 'file_get_contents' method * to get response string / $responseString = file_get_contents($url); } else { / * if $curl, use 'curl' method * to get response string */

// Initializing curl
$ch = curl_init( $url );

// Configuring curl options
$options = array(
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => array('Content-type: application/json') ,
    //Could be xml
);

// Setting curl options
curl_setopt_array( $ch, $options );

// Getting JSON encoded string
$responseString =  curl_exec($ch);

}
return $responseString;
}
