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

$url="http://localhost/upload.php";$path = "/bg_right.jpg"

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);?>

希望本文所述对大家PHP程序设计有所帮助。
