PHP7基于curl实现的上传图片功能php技巧

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：

$curl = curl_init();if (html' target='_blank'>class_exists( /CURLFile )) { curl_setopt($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));// =5.5curl_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);?
