  本文实例讲述了PHP7基于curl实现的上传图片功能。分享给大家供大家参考,具体如下:

  根据php版本不同,curl模拟表单上传的方法不同

  php5.5之前

   $curl = curl_init(); if (defined(CURLOPT_SAFE_UPLOAD)) { curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false); } $data = array(file => @ . realpath($path));//‘@ 符号告诉服务器为上传资源 curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, 1 ); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_USERAGENT,TEST); $result = curl_exec($curl); $error = curl_error($curl);

  php5.5之后,到php7

   $curl = curl_init(); curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true); $data = array(file => new \CURLFile(realpath($path))); url_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, 1 ); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_USERAGENT,TEST); $result = curl_exec($curl); $error = curl_error($curl);

  下面提供一个兼容的方法:

   $curl = curl_init(); if (class_exists(\CURLFile)) { curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true); $data = array(file => new \CURLFile(realpath($path)));//>=5.5 } else { if (defined(CURLOPT_SAFE_UPLOAD)) { curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false); } $data = array(file => @ . realpath($path));//<=5.5 } curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, 1 ); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_USERAGENT,TEST); $result = curl_exec($curl); $error = curl_error($curl);

  其中:

  $path:为待上传的图片地址

  $url:目标服务器地址

  例如

   $url=

  upload.php示例:

   <?php file_put_contents(time()..json, json_encode($_FILES)); $tmp_name = $_FILES[file][tmp_name]; $name = $_FILES[file][name]; move_uploaded_file($tmp_name,audit/.$name); ?>
