PHP7基于curl实现的上传图片功能
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
- } //phpfensi.com
- 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);
- ?>
