Curl JSON function for PHP

As I’m always working with various JSON based APIs in PHP which don’t have dedicated libraries, heres my simple ‘default’ Curl JSON function for PHP.

curl_json.php

<?php
 
        function curl_json($base_url='',$query='',$json=true){
 
                //set the url to use
                $target_url = 'http://www.mydomain.com/json_script.json';
                $url == ($base_url='' ? $target_url : $base_url)  ;
 
                //set default json
                $default_json ='[you json string here]';
                $json_query == ($query='' ? $query : $default_json) ;
                
                //http auth
                $username = 'your_username';  // authentication
                $password = 'your_password';  // authentication
 
                $ch = curl_init();
                $headers = array();
                if($json) {
                        $headers[] = 'Content-type: application/json';
                        $headers[] = 'X-HTTP-Method-Override: GET';
                }
                $options = array(
                                CURLOPT_URL => $url,
                                CURLOPT_RETURNTRANSFER => true,
                                CURLOPT_USERPWD => $username . ":" . $password,   // authentication
                                CURLOPT_HTTPHEADER => array($headers),
                                CURLOPT_POSTFIELDS => $json_query,
                                CURLOPT_TIMEOUT => 5,
                                CURLOPT_RETURNTRANSFER => 1,
                                CURLOPT_HEADER => 0,
                                CURLOPT_FOLLOWLOCATION => 1,
                                CURLOPT_MAXREDIRS => 3,
                                CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)'
                                );
                curl_setopt_array($ch,$options);
                $response = curl_exec($ch);
                if($response === false || curl_error($ch)) {
                        curl_close($ch);
                        return false;
                } else {
                        curl_close($ch);
                        return json_decode($response, true);
                }
        }
?>

Just alter the target url, auth setting, and set any default json query and your good to go.
