一、简单的写一个html页面用来提交文件

二、处理上传的文件

<?php
    /**
     * Created by PhpStorm.
     * User: dudongjiang
     * Date: 2016/12/1
     * Time: 10:10
     * effort: 微信素材上传
     */
    /**
     * @param $file_info
     * @return bool|mixed
     * @effort 处理
     */
    function add_material($file_info){
        $path = $file_info['media']['name'];
        $type = 'image';
        $access_token=get_access_token();
        $url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=$type";
        $ch1 = curl_init ();
        curl_setopt ( $ch1, CURLOPT_SAFE_UPLOAD, false);
        $filepath = dirname(__FILE__)."\/$path";
        $data= array('media'=>"@".$filepath);
        curl_setopt($ch1, CURLOPT_URL, $url);
        curl_setopt($ch1, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch1, CURLOPT_SSL_VERIFYHOST, FALSE);
        if (!empty($data)){
            curl_setopt($ch1, CURLOPT_POST, 1);
            curl_setopt($ch1, CURLOPT_POSTFIELDS, $data);
        }
        curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec ( $ch1 );
        curl_close ( $ch1 );
        return $result;
    }
    
    /**
     * @return mixed
     * @effort 将微信自带的验证缓存起来 防止超限
     */
    function get_access_token() {
        $tokenFile = "./access_token.txt";//缓存文件名
        $data = json_decode(file_get_contents($tokenFile));
        if ($data->expire_time < time() or !$data->expire_time) {
            $appid = "自己的appid";
            $appsecret = "自己的appsecret";
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";
            $res = getJson($url);
            $access_token = $res['access_token'];
            if($access_token) {
                $newdata['expire_time'] = time() + 7000;
                $newdata['access_token'] = $access_token;
                $fp = fopen($tokenFile, "w");
                fwrite($fp, json_encode($newdata));
                fclose($fp);
            }
        } else {
            $access_token = $data->access_token;
        }
        return $access_token;
    }
    
    //取得微信返回的JSON数据
    function getJson($url){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL ,$url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER ,FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST ,FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER ,1);
        $output = curl_exec($ch);
        curl_close($ch);
        return json_decode($output, true);
    }
    
    $result = add_material($_FILES);
    var_dump($result);

三、执行的结果

\{"type":"image","media\_id":"iR9397zl0j-Jr6wQpGhjc4rM-Nq4GaepLXhxiCd\_8N2gBBoAk-J1nkk2l33Em94L","created\_at":1480575046\}

四、注意

1.php的版本

php5.5.0中添加 默认值FALSE php5.6.0中默认值为TRUE

CURLOPT\_SAVE\_UPLOAD的值为TRUE禁用@前缀CURLOPT\_POSTFIELDS中发送邮件。意味着@可以在字段中安全的使用了

PHP 5.5.0 中添加，默认值 **FALSE**。 PHP 5.6.0 改默认值为 **TRUE**。  
2.路径  
一定要使用绝对路劲  
在windows下为@D:\\www\\apache\\images\\dudj.jpg  
在linux下@home/apache/picture/lkk.jpg

一定要注意红色部分和注意点
