一、上传文件： 1、 php.ini配置: 找到 File Uploads file_uploads = On //打开上传文件的功能 upload_tmp_dir = 'd:/web/tmp' ; //上传文件的临时存储目录；取决于web服务器部署目录 upload_max_filesize 3M; //允许上传文件最大值,如若需要较大的值，则需先修改post方式的传输最大值 post_max_size =8M; 2、 .htaccess 配置 属性和值之间用空格‘ ’隔开非等号‘=’：
adddefaultcharset utf-8 //设置默认字符
php_value file_uploads On //打开上传功能
php_value post_max_size 6M // post提交的最大值
php_value upload_max_filesize 6M //允许上传的最大值
（一）上传单个文件：
html 表单：
<form action="upload.php" method="post" enctype="multipart/form-data">
<p><input type="file" name="ufile"></p>
<p><input type="submit" name="submit" value="上传"></p>
</form>
PHP接受处理上传文件
//主要为move_uploaed_file() 的运用
if (!empty($_POST)) {
$dirName = "./".date("Y-m-d");
if (!is_dir($dirName)) {
mkdir($dirName); //如无此目录则创建
}
$suffix = strrchr($_FILES['ufile']['name'], '.');//截取文件的后缀名
$url = $dirName.'/'.uniqid().$suffix; //在日期的目录里以原来的后缀名以唯一性的文件名保存
$bool = move_uploaded_file($_FILES['ufile']['tmp_name'], $url); //从原来的临时文件移动到指定路径
if ($bool) {
echo "上传成功！";
exit();
}else{
echo "上传失败！";
exit();
}
}
（二）上传多个文件：
<form action="upload.php" method="post" enctype="multipart/form-data">
<p><input type="file" name="ufile[]" multiple=""></p>
<p><input type="submit" name="submit" value="上传"></p>
</form>
if(!empty($_POST)){
//创建保存目录
$dirName = "./".date('Y-m-d');
if (!is_dir($dirName)) {
mkdir($dirName);
}
foreach ($_FILES['ufile']['tmp_name'] as $key => $value) {
//取文件后缀 ($key与$_FILES['ufile']['name']数组的key一致)
$suffix = strrchr($_FILES['ufile']['name'][$key],'.');
//生成前缀
$preffix = uniqid();
//保存路径
$url = $dirName."/".$preffix.$suffix;
$bool = move_uploaded_file($value,$url);
}
if ($bool) {
echo "上传成功！";
exit();
}else{
echo "上传失败！";
exit();
}
}
thinkPHP3.2.3 引入编辑器 1、下载 http://kindeditor.net/down.php 压缩包加压到指定目录； 2、引入css及js 加上带id的文本框
<link rel="stylesheet" href="__PUBLIC__/kindeditor-master/themes/default/default.css"> <!-- 编辑器css -->
<div>
<label class="control-label">图文信息 </label>
<div class="controls">
<p><textarea id="ke_c" name="detail" cols="26" rows="26"> </textarea></p>
</div>
</div>
<script src="__PUBLIC__/kindeditor-master/kindeditor-all-min.js"></script> <!-- 编辑器js -->
<script src="__PUBLIC__/kindeditor-master/lang/zh-CN.js"></script>
<script>
var editor;
KindEditor.ready(function(K) {
K.create('#ke_c', {
allowFileManager : true
});
});
</script>
3、在编辑器压缩包的目录下创建名为attached的目录并修改目录为写入权限； 二、下载文件 A. 当文件为浏览器不能识别的类型时，可直接用a标签实现下载 , 如： <a href="../load/ay.xls">下载</a> B.当文件为浏览器能识别的类型时，即如.html/.js/.css/.xml/.jpg/.jpeg等浏览器能解析直接打开的文件，可用header( ) 及file_get_contents( ) 实现，如： <a href="download.php">下载</a>
$filename = "./load/5b0bd336b7980.jpg";
//提示浏览器为图片文件
header('Content-type: image/jpeg');
//Content-Disposition为内容处理方式,处理为附件，强制浏览器下载文件
header('Content-Disposition: attachment; filename='.$filename);
//将整个文件读入一个字符串，即将二进制对象转为utf-8编码
echo file_get_contents($filename);
常见header( ) 响应头设置：
//定义编码
header( 'Content-Type:text/html;charset=utf-8 ');
//文档语言
header('Content-language: en');
//CSS
header('Content-type: text/css');
//Javascript
header('Content-type: text/javascript');
//JPEG Image
header('Content-type: image/jpeg');
//XML
header('Content-type: text/xml');
//JSON
header('Content-type: application/json');
//PDF
header('Content-type: application/pdf');
//RSS
header('Content-Type: application/rss+xml; charset=ISO-8859-1');
//Text (Plain)
header('Content-type: text/plain');
//Atom
header('Content-type: application/atom+xml');
//转到一个新地址
header('Location: http://www.example.org/');
// ok
header('HTTP/1.1 200 OK');
//设置一个404头:
header('HTTP/1.1 404 Not Found');
//设置地址被永久的重定向
header('HTTP/1.1 301 Moved Permanently');
//文件延迟转向:
header('Refresh: 10; url=http://www.example.org/');
print 'You will be redirected in 10 seconds';
//当然，也可以使用html语法实现
// <meta http-equiv="refresh" content="10;http://www.example.org/ />
// override X-Powered-By: PHP:
header('X-Powered-By: PHP/4.4.0');
header('X-Powered-By: Brain/0.6b');
//告诉浏览器最后一次修改时间
$time = time() - 60; // or filemtime($fn), etc
header('Last-Modified: '.gmdate('D, d M Y H:i:s', $time).' GMT');
//告诉浏览器文档内容没有发生改变
header('HTTP/1.1 304 Not Modified');
//设置内容长度
header('Content-Length: 1234');
//设置为一个下载类型
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="example.zip"');
header('Content-Transfer-Encoding: binary');
// load the file to send:
readfile('example.zip');
// 对当前文档禁用缓存
header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Pragma: no-cache');
//设置内容类型:
header('Content-Type: text/html; charset=iso-8859-1');
header('Content-Type: text/html; charset=utf-8');
header('Content-Type: text/plain'); //纯文本格式
header('Content-Type: image/jpeg'); //JPG***
header('Content-Type: application/zip'); // ZIP文件
header('Content-Type: application/pdf'); // PDF文件
header('Content-Type: audio/mpeg'); // 音频文件
header('Content-Type: application/x-shockw**e-flash'); //Flash动画
//显示登陆对话框
header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic realm="Top Secret"');
print 'Text that will be displayed if the user hits cancel or ';
print 'enters wrong login data';
//下载xlsx文件
$filename = rtrim($_SERVER['DOCUMENT_ROOT'],'/').'/app/files/payment_status.csv';
header('Content-Disposition: attachment; filename=payment_status.xlsx');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Length: ' . filesize($filename));
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate');
header('Pragma: public');
readfile($filename);
