我想将$remote\\u id读取为整数，$remote\\u id应该是执行metaweblog后的post\\u id。newpost。有人知道如何将数据转换为整数吗？

以下是代码：

$MAINURL = "http://mywordpress.com";
$USERNAME = "username";
$PASSWORD = "password";

function get_response($URL, $context) {
if(!function_exists(\'curl_init\')) {
die ("Curl PHP package not installed\\n");
}

/*Initializing CURL*/
$curlHandle = curl_init();

/*The URL to be downloaded is set*/
curl_setopt($curlHandle, CURLOPT_URL, $URL);
curl_setopt($curlHandle, CURLOPT_HEADER, false);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $context);

/*Now execute the CURL, download the URL specified*/
$response = curl_exec($curlHandle);
return $response;
}

/*Creating the metaWeblog.newPost request which takes on five parameters
blogid,
username,
password*/

/*The title of your post*/
$title = "Sample Post from main site";

/*The contents of your post*/
$description = "This is a sample post from main site";

/*Forming the content of blog post*/
$content[\'title\'] = $title;
$content[\'description\'] = $description;
$content[\'categories\'] = array("mycategoryname");
$content[\'post_status\'] = \'publish\';  /* \'publish\' or \'draft\' or \'pending\'
/*Whether the post has to be published*/
$toPublish = true;


$request = xmlrpc_encode_request("metaWeblog.newPost", 
array(1,$USERNAME, $PASSWORD, $content, $toPublish));

/*Making the request to wordpress XMLRPC of your blog*/
$xmlresponse = get_response($MAINURL."/xmlrpc.php", $request);
$remote_id = xmlrpc_decode($xmlresponse);

echo $remote_id;

$MAINURL = "http://mywordpress.com";
$USERNAME = "username";
$PASSWORD = "password";

function get_response($URL, $context) {
if(!function_exists(\'curl_init\')) {
die ("Curl PHP package not installed\\n");
}

/*Initializing CURL*/
$curlHandle = curl_init();

/*The URL to be downloaded is set*/
curl_setopt($curlHandle, CURLOPT_URL, $URL);
curl_setopt($curlHandle, CURLOPT_HEADER, false);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $context);

/*Now execute the CURL, download the URL specified*/
$response = curl_exec($curlHandle);
return $response;
}

$title = "Sample Post from main site";

$content[\'title\'] = $title;

$content[\'categories\'] = array("mycategoryname");
$content[\'post_status\'] = \'publish\';  /* \'publish\' or \'draft\' or \'pending\'
/*Whether the post has to be published*/
$toPublish = true;


$request = xmlrpc_encode_request("metaWeblog.newPost", 
array(1,$USERNAME, $PASSWORD, $content, $toPublish));

/*Making the request to wordpress XMLRPC of your blog*/
$xmlresponse = get_response($MAINURL."/xmlrpc.php", $request);
$remote_id = xmlrpc_decode($xmlresponse);

echo $remote_id;
