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); ?>
