想了解PHP7基于curl实现的上传图片功能的相关内容吗,BroceHui在本文为您仔细讲解PHP7 curl上传图片的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:PHP7,curl,上传图片,下面大家一起来学习吧。

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);
?>

希望本文所述对大家PHP程序设计有所帮助。
