headerphp设置
Ⅰ php header 怎么设置
PHP设置header示例：
<?php
//设置页面编码
header("Content-type:/text/html;charset=utf-8;");
//页面重定向跳转示例
header("location:index.php");
Ⅱ php 输出视频流怎样设置header
header 好像不识别变量吧
我这也有一个函数 但是只能播放mp4的文件 如果你的能播放其他的视频格式求分享
function PutMovie($file) {
header("Content-type: video/mp4");
header("Accept-Ranges: bytes");
$size = (filesize($file));
if(isset($_SERVER['HTTP_RANGE'])){
header("HTTP/1.1 206 Partial Content");
list($name, $range) = explode("=", $_SERVER['HTTP_RANGE']);
list($begin, $end) =explode("-", $range);
if($end == 0) $end = $size - 100;
}
else {
$begin = 0; $end = $size - 100;
}
header("Content-Length: " . ($end - $begin + 1));
header("Content-Disposition: filename=".basename($file));
header("Content-Range: bytes ".$begin."-".$end."/".$size);
$fp = fopen($file, 'rb');
fseek($fp, $begin);
while(!feof($fp)) {
$p = min(1024, $end - $begin + 1);
$begin += $p;
echo fread($fp, $p);
}
fclose($fp);exit;
}
Ⅲ php设置编码的头文件怎样写
php设置编码默认就是utf8编码
utf编码 ：header("Content-type: text/html; charset=utf-8");
gbk编码 ：header("Content-type: text/html; charset=gb2312");
big5编码 ：header("Content-type: text/html; charset=big5");
注意事项：通常情况以上代码放在php页面的首页。
(3)headerphp设置扩展阅读：
PHP优势
1.开放的源代码：所有的PHP源代码事实上都可以得到。
2.免费的：和其它技术相比，PHP本身免费且是开源代码。
3.快捷性：程序开发快，运行快，技术本身学习快。
4.跨平台性强：PHP是运行在服务器端的脚本，可运行在UNIX、LINUX、WINDOWS、Mac OS下。
5.效率高：PHP消耗相当少的系统资源。
6.图像处理：用PHP动态创建图像。
7.面向对象：在php4，php5中，面向对象方面都有了很大的改进，php完全可以用来开发大型商业程序。
8.专业专注：PHP支持脚本语言为主，同为类C语言。
Ⅳ php的header函数设置在哪
//ok
header(‘HTTP/1.1200OK');
//设置一个404头:
header(‘HTTP/1.1404NotFound');
//设置地址被永久的重定向
header(‘HTTP/1.1301MovedPermanently');
//转到一个新地址
header(‘Location:http://www.example.org/‘);
//文件延迟转向:
header(‘Refresh:10;url=http://www.example.org/‘);
print‘';
//当然，也可以使用html语法实现
//<metahttp-equiv=”refresh”content=”10;http://www.example.org//>
//overrideX-Powered-By:PHP:
header(‘X-Powered-By:PHP/4.4.0′);
header(‘X-Powered-By:Brain/0.6b');
//文档语言
header(‘Content-language:en');
//告诉浏览器最后一次修改时间
$time=time()–60;//orfilemtime($fn),etc
header(‘Last-Modified:‘.gmdate(‘D,dMYH:i:s',$time).'GMT');
//告诉浏览器文档内容没有发生改变
header(‘HTTP/1.1304NotModified');
//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');
//loadthefiletosend:
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,26Jul199705:00:00GMT');//Dateinthepast
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/1.1401Unauthorized');
header(‘WWW-Authenticate:Basicrealm=”TopSecret”‘);
print‘‘;
print‘enterswronglogindata';
Ⅳ 为什么php设置了header输出的是乱码
检查文件的编码格式，用记事本打开，另存为的时候，看一下下方的编码格式，是ANSI的还是UTF-8的，
另外建议用Notepad++之类的编辑器，会比较快速处理这样的问题，直接在顶部菜单的“格式”，“以utf-8 无BOM格式编码”（注意要提前备份，因为如果你本身是gbk格式的，并且直接这样操作，会有可能把文件中的中文变成了乱码，可以先全选文件，剪切一下，再转换编码后，再粘贴上来，就OK了）
Ⅵ PHP中使用header("Content
<?php
header("Content-type: image/gif");
$im = imagecreate(100,50);
$bl = imagecolorallocate($im,0,255,0);
imagefill($im,0,0,$bl);
imagegif($im);
imagedestroy($im);
?>
把你的代码保存成单独文件，如名为：img.php 在其它文件中这样调用
<img src="img.php">
Ⅶ php设置网页头header参数有哪些
header(string,replace,http_response_code)
string 必需。规定要发送的报头字符串。
replace 可选。指示该报头是否替换之前的报头，或添加第二个报头。
默认是 true（替换）。false（允许相同类型的多个报头）。
http_response_code 可选。把 HTTP 响应代码强制为指定的值。（PHP 4 以及更高版本可用）
header("Content-type:text/html;charset=utf-8");
Ⅷ php中header（）作用
header的用法
标头 (header) 是服务器以 HTTP 协义传 HTML 资料到浏览器前所送出的字串，在标头
与 HTML 文件之间尚需空一行分隔。有关 HTTP 的详细说明，可以参 RFC 2068 官方文件
(http://www.w3.org/Protocols/rfc2068/rfc2068)。在 PHP 中送回 HTML 资料前，需先
传完所有的标头。
注意: 传统的标头一定包含下面三种标头之一，并只能出现一次。
Content-Type: xxxx/yyyy
Location: xxxx:yyyy/zzzz
Status: nnn xxxxxx
在新的多型标头规格 (Multipart MIME) 方可以出现二次以上。
使用范例
范例一: 本例使浏览器重定向到 PHP 的官方网站。
Header("Location: http://www.php.net";);
exit;
>?
范例二: 要使用者每次都能得到最新的资料，而不是 Proxy 或 cache 中的资料，可以使用下列的标头
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
>?
范例三: 让使用者的浏览器出现找不到档案的信息。
header("Status: 404 Not Found");
>?
范例四:让使用者下载档案。
header("Content-type: application/x-gzip");
header("Content-Disposition: attachment; filename=文件名\");
header("Content-Description: PHP3 Generated Data");
?>
header重定向 就等价于替用户在地址栏输入url
---------------------------------
//刚好找到比较详细的资料!
Ⅸ PHP如何用header设置文件下载头！感谢~
$filename = '文件路径';
//文件的类型
header('Content-type: application/pdf');
//下载显示的名字
header('Content-Disposition: attachment; filename="保存时的文件名.pdf"');
readfile("$filename");
exit;

Ⅹ php中header头设置无效的原因可能有哪些
一般来说在header函数前不能输出html内容，类似的还有setcookie() 和 session 函数，这些函数需要在输出流中增加消息头部信息。
如果在header()执行之前有echo等语句，当后面遇到header()时，就会报出 “Warning: Cannot modify header information – headers already sent by ….”错误。
就是说在这些函数的前面不能有任何文字、空行、回车等，而且最好在header()函数后加上exit()函数。
