使用PHP做 http pxory 缓存&代理, 使用 redis 做缓存,支持毫秒过期,拥有超高性能

<?php

//PHP http pxory 缓存&代理, 使用redis做缓存,支持毫秒过期,拥有超高性能

$url=@$_GET['url'];

if (empty($_GET['url'])) {

echo 'url is empty ';

exit;

$path=parse_url($url, PHP_URL_PATH);

$key=$path;

$redis = new Redis();

$redis->pconnect('127.0.0.1', 6379);

if ($content=$redis->get($key)) {

echo $content;

exit;

// Client

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_NOSIGNAL, 1); //注意，毫秒超时一定要设置这个

curl_setopt($ch, CURLOPT_TIMEOUT_MS, 500); //超时毫秒，cURL 7.16.2中被加入。从PHP 5.2.3起可使用

$data = curl_exec($ch);

$curl_errno = curl_errno($ch);

$curl_error = curl_error($ch);

curl_close($ch);

if ($curl_errno > 0) {

echo "cURL Error ($curl_errno): $curl_error\n";

} else {

// $redis->setEx('key', 3600, 'value');//以秒为单位

$redis->pSetEx($key, 50000, $data); // 将参数中的字符串值设置为键的值，并带有生存时间 pSetEx以毫秒为单位.

echo $data;

exit;

<?php

     echo $data;
     exit;
}
