這篇文章主要介紹了PHP7基於curl實現的上傳圖片功能,結合實例形式對比分析了php5.5之前與php7版本的curl圖片上傳功能相關實現與使用技巧,需要的朋友可以參考下
本文實例講述了PHP7基於curl實現的上傳圖片功能。分享給大家供大家參考,如下:
依php版本不同,curl模擬表單上傳的方法不同
##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之後,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);下面提供一個相容的方法:
$curl = curl_init(); if (class_exists('\CURLFile')) { curl_setopt($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:為待上傳的圖片位址
$url:目標伺服器位址
例如$url="http://localhost/upload.php"; $path = "/bg_right.jpg"upload.php範例:
<?php file_put_contents(time().".json", json_encode($_FILES)); $tmp_name = $_FILES['file']['tmp_name']; $name = $_FILES['file']['name']; move_uploaded_file($tmp_name,'audit/'.$name); ?>您可能感興趣的文章:
