PHP 5.4.31 Released

Phar::webPhar

(PHP >= 5.3.0, PECL phar >= 2.0.0)

Phar::webPharmapPhar for web-based phars. front controller for web applications

Description

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

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).

Parameters

alias

The alias that can be used in phar:// 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. By default, these extensions are mapped to these mime types:

<?php
$mimes 
= array(
    
'phps' => 2// 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' => 1// parse as PHP
    
'inc' => 1// 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

An array mapping URI to internal file, simulating mod_rewrite of apache. For example:

<?php
array(
    
'myinfo' => 'myinfo.php'
);
?>
would route calls to http://<host>/myphar.phar/myinfo to the file phar:///path/to/myphar.phar/myinfo.php, preserving GET/POST. This does not quite work like mod_rewrite in that it would not match http://<host>/myphar.phar/myinfo/another.

Return Values

No value is returned.

Errors/Exceptions

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 mimetypes or to rewrites, then UnexpectedValueException is thrown.

Examples

Example #1 A Phar::webPhar() example

With the example below, the created phar will display Hello World if one browses to /myphar.phar/index.php or to /myphar.phar, and will display the source of index.phps if 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
}
?>

  • 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".
