问题描述

我有以下代码:

<?php
header('Content-Type: image/png');
$data = "iVBORw0KGgoAAAANSUhEUgAAAuAAAAI8CAYAAACwIh5dAAAgAElkZJgRCXxOAuIPzzTlg......";       
define('UPLOAD_DIR', '/home/Desktop/image.png');
$img = $data;
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
?>

此处$data包含base-64中图像的编码字符串.我想将图像保存到文件中.我之前的代码也通过了Google的许多教程，但无法正常工作.

推荐答案

首先指定正确的路径，例如:

First specify the correct path like :

define('UPLOAD_DIR', '/home/Desktop/');

在检查您提供的路径是否设置了读/写权限之后.

After check that the path you provided has read/write permission set or not.
