用curl_file_create函数配合curl实现文件上传，增强代码的健壮性

<?php
if (!function_exists('curl_file_create')) {
     function curl_file_create($filename, $mimetype = '', $postname = '') {
         return "@$filename;filename="
             . ($postname ?: basename($filename))
             . ($mimetype ? ";type=$mimetype" : '');
     }
 }

$ch = curl_init();
$filename1 = 'E:/html/pim/php_weili_activities/uploads/activity_13_1547717462.jpg';
$filename2 = 'E:/html/pim/php_weili_activities/uploads/activity_13_1546510239_thumb.jpg';
$minetype1 = 'image/jpeg';
$minetype2 = 'image/jpeg';
$curl_file1 = curl_file_create($filename1,$minetype1,pathinfo($filename1,PATHINFO_BASENAME));
$curl_file2 = curl_file_create($filename2,$minetype2,pathinfo($filename2,PATHINFO_BASENAME));
$postData = [
    'file' => '111',
    'text' => '666',
    //'file'=>$curl_file1, //单个文件上传
    'file[0]'=>$curl_file1, //多个文件上传
    'file[1]'=>$curl_file1, //多个文件上传
];

curl_setopt($ch, CURLOPT_URL, 'http://localhost/phpinfo.php');
//curl结果不直接输出
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//发送post  请求
curl_setopt($ch, CURLOPT_POST, 1);
// urlencoded 后的字符串，类似'para1=val1&para2=val2&...'，也可以使用一个以字段名为键值，字段数据为值的数组 ,测试当值为数组时候  Content-Type头将会被设置成multipart/form-data 否则Content-Type 头会设置为 application/x-www-form-urlencoded
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); //数组时候，以multipart/form-data提交
//curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData)); //application/x-www-form-urlencoded提交

//允许 cURL 函数执行的最长秒数
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
//不输出header 头信息
curl_setopt($ch, CURLOPT_HEADER,0);
//输出请求头
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE); //输出请求头，用curl_getinfo获取请求头
//不验证证书 信任任何证书
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// 检查证书中是否设置域名,0不验证 0：不检查通用名称（CN）属性
//1：检查通用名称属性是否存在
//2：检查通用名称是否存在，是否与服务器的主机名称匹配
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
//设置 在HTTP请求中包含一个"User-Agent: "头的字符串
//curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

$res = curl_exec($ch);
$error_no = curl_errno($ch);
$info = curl_getinfo($ch);
$err_msg = '';
if ($error_no) {
    $err_msg = curl_error($ch);
} else {
    print_r($res);
    //var_dump($info); //CURLINFO_HEADER_OUT选项为true设置下，可获取请求头信息
}
curl_close($ch);
