wordpress随机获取2000条链接，并向百度主动推送

百度可以利用php实现接口推送，百度给的示列如下：

$urls = array(
    'http://www.example.com/1.html',
    'http://www.example.com/2.html',
);
$api = '你的接口调用地址';
$ch = curl_init();
$options =  array(
    CURLOPT_URL => $api,
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POSTFIELDS => implode("\n", $urls),
    CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),
);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
echo $result;

$urls一条条写太麻烦了，如何利用php语法+mysql语法直接从数据库中随机获取2000条数据推送！

具体代码如下：

<?php
include ( "wp-config.php" ) ;
require_once (ABSPATH.'wp-blog-header.php');
global $wpdb;

//填你的前缀
$qianzui = "https://ipkd.cn/webs_";

//填你的后缀
$houzui = ".html";

//获取所有文章 url
$sql="SELECT ID FROM wp_posts WHERE post_type = 'post' AND post_status = 'publish'
 ORDER BY RAND() LIMIT 2000 ";
$myrows = $wpdb->get_results($sql);
$urls = array();
foreach ($myrows as $b) {
    $id = $b->ID;
    $urls[] =$qianzui.$id.$houzui;
}

$api = '你的接口调用地址';
$ch = curl_init();
$options =  array(
    CURLOPT_URL => $api,
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POSTFIELDS => implode("\n", $urls),
    CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),
);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
echo $result;
?>
