[英]PHP: how to serve right content-type (depending on file extension?)?
I'm using the scripts below to gzip some CSS and JS files. 我正在使用以下脚本gzip一些CSS和JS文件。 It works nice - except for serving JS files with the wrong content-type (and not the appropriate application/x-javascript).
效果很好-除了使用错误的内容类型(而不是适当的application / x-javascript)提供JS文件之外。 How could I improve the PHP code in order to serve the right content-type?
如何改善PHP代码以提供正确的内容类型? Thanks!
谢谢!
.htaccess: 的.htaccess:
AddHandler application/x-httpd-php .css .js
php_value auto_prepend_file gzip.php
gzip.php: gzip.php:
<?php
ob_start ("ob_gzhandler");
header("Content-type: text/css; charset: UTF-8");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 ;
$ExpStr = "Expires: " .
gmdate("D, d M Y H:i:s",
time() + $offset) . " GMT";
header($ExpStr);
?>
You could check the ending of the requested URL path: 您可以检查所请求的URL路径的结尾:
$_SERVER['REQUEST_URI_PATH'] = strtok($_SERVER['REQUEST_URI'], '?');
$extensionToType = array(
'.css' => 'text/css;charset=utf-8',
'.js' => 'application/javascript;charset=utf-8'
);
$extension = strrchr($_SERVER['REQUEST_URI_PATH'], '.');
if (isset($extensionToType[$extension])) {
header("Content-type: ".$extensionToType[$extension]);
} else {
header("Content-type: application/octet-stream");
}
您也可以使用FileInfo而不是使用扩展名来检查mime类型。
