在php页面如何调用接口,php之web页面之间的接口调用

//调用页面testgetjson.php

require_once("../json/json.php");

$strJson = file_get_contents('http://localhost/lian/testpostjson.php', 1000000);

echo "get json string:
/n";

echo "$strJson
/n";

$objJson = new Services_JSON();

$obj = $objJson->decode($strJson);

echo "the orgin data:
/n";

var_dump($objJson);

var_dump($obj);

echo "
/n";

?>

//被调用页面 testpostjson.php

require_once("../json/json.php");

$arr = array('name' => 'andylin', 'nick' => 'congfeng', 'contact' => array('email' =>'andylin02@126.com', 'website' => 'http://blog.csdn.net/andylin02'));

$objJson = new Services_JSON();

$strJson = $objJson->encode($arr);

echo "$strJson";

?>
