mapPhar for web-based phars. front controller for web applications

说明

finalpublicstaticPhar::webPhar([string $alias[,string $index= "index.php"[,string $f404[,array $mimetypes[,callable $rewrites]]]]]): void

Phar::mapPhar() for web-based phars. This method parses$_SERVER['REQUEST_URI']and routes a request from a web browser to an internal file within the phar archive. In essence, it simulates a web server, routing requests to the correct file, echoing the correct headers and parsing PHP files as needed. This powerful method is part of what makes it easy to convert an existing PHP application into a phar archive. Combined with Phar::mungServer() and Phar::interceptFileFuncs(), any web application can be used unmodified from a phar archive.

Phar::webPhar() should only be called from the stub of a phar archive(see here for more information on what a stub is).

参数

$alias

The alias that can be used inphar://URLs to refer to this archive, rather than its full path.

$index

The location within the phar of the directory index.

$f404

The location of the script to run when a file is not found. This script should output the proper HTTP 404 headers.

$mimetypes

An array mapping additional file extensions to MIME type. If the default mapping is sufficient, pass an empty array. By default, these extensions are mapped to these MIME types:

<?php
$mimes = array(
    'phps' => Phar::PHPS, // pass to highlight_file()
    'c' => 'text/plain',
    'cc' => 'text/plain',
    'cpp' => 'text/plain',
    'c++' => 'text/plain',
    'dtd' => 'text/plain',
    'h' => 'text/plain',
    'log' => 'text/plain',
    'rng' => 'text/plain',
    'txt' => 'text/plain',
    'xsd' => 'text/plain',
    'php' => Phar::PHP, // parse as PHP
    'inc' => Phar::PHP, // parse as PHP
    'avi' => 'video/avi',
    'bmp' => 'image/bmp',
    'css' => 'text/css',
    'gif' => 'image/gif',
    'htm' => 'text/html',
    'html' => 'text/html',
    'htmls' => 'text/html',
    'ico' => 'image/x-ico',
    'jpe' => 'image/jpeg',
    'jpg' => 'image/jpeg',
    'jpeg' => 'image/jpeg',
    'js' => 'application/x-javascript',
    'midi' => 'audio/midi',
    'mid' => 'audio/midi',
    'mod' => 'audio/mod',
    'mov' => 'movie/quicktime',
    'mp3' => 'audio/mp3',
    'mpg' => 'video/mpeg',
    'mpeg' => 'video/mpeg',
    'pdf' => 'application/pdf',
    'png' => 'image/png',
    'swf' => 'application/shockwave-flash',
    'tif' => 'image/tiff',
    'tiff' => 'image/tiff',
    'wav' => 'audio/wav',
    'xbm' => 'image/xbm',
    'xml' => 'text/xml',
);
?>

$rewrites

The rewrites function is passed a string as its only parameter and must return a string or FALSE.

If you are using fast-cgi or cgi then the parameter passed to the function is the value of the$_SERVER['PATH_INFO']variable. Otherwise, the parameter passed to the function is the value of the$_SERVER['REQUEST_URI']variable.

If a string is returned it is used as the internal file path. If FALSE is returned then webPhar()will send a HTTP 403 Denied Code.

返回值

没有返回值。

错误／异常

Throws PharException when unable to open the internal file to output, or if called from a non-stub. If an invalid array value is passed into$mimetypesor an invalid callback is passed into$rewrites, then UnexpectedValueException is thrown.

范例

A Phar::webPhar() example

With the example below, the created phar will displayHello Worldif one browses to/myphar.phar/index.phpor to/myphar.phar, and will display the source ofindex.phpsif one browses to/myphar.phar/index.phps.

<?php
// creating the phar archive:
try {
    $phar = new Phar('myphar.phar');
    $phar['index.php'] = '<?php echo "Hello World"; ?>';
    $phar['index.phps'] = '<?php echo "Hello World"; ?>';
    $phar->setStub('<?php
Phar::webPhar();
__HALT_COMPILER(); ?>');
} catch (Exception $e) {
    // handle error here
}
?>

参见

• Phar::mungServer() Defines a list of up to 4 $_SERVER variables that should be modified for execution
• Phar::interceptFileFuncs() Instructs phar to intercept fopen, file_get_contents, opendir, and all of the stat-related functions

It seems that calling Phar::webPhar() from inside a function is a bad idea. Doing so will cause global variables in included files to not be global. For instance, do NOT try this:
<?php
$phar = new Phar('test.phar.php');
$phar['test.php'] = '<?php
$FOO = "globals work";
function test() {
 global $FOO;
 echo "test: $FOO\n";
}
test();
?>';
$phar->setStub('<?php
function _bootstrap() {
Phar::webPhar();
}
_bootstrap();
__HALT_COMPILER(); ?>');
?>
The output will be "test:", not "test: globals work".
