PHP7基於curl實現的上傳圖片功能php技巧

這篇文章主要介紹了PHP7基於curl實現的上傳圖片功能,結合執行個體形式對比分析了php5.5之前與php7版本的curl圖片上傳功能相關實現與提示,需要的朋友可以參考下

本文執行個體講述了PHP7基於curl實現的上傳圖片功能。分享給大家供大家參考，具體如下：

根據php版本不同，curl類比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));//‘@' 符號告訴伺服器為上傳資源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：為待上傳的圖片地址

$url：目標伺服器地址

例如

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

upload.php樣本：

<?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);?>
