PHP Manual: Phar::createDefaultStub

Description

final public static function Phar::createDefaultStub(?string $index = null, ?string $webIndex = null): string

This method is intended for creation of phar-file format-specific stubs, and is not intended for use with tar- or zip-based phar archives.

Phar archives contain a bootstrap loader, or stub written in PHP that is executed when the archive is executed in PHP either via include:

<?php
include 'myphar.phar';
?>

or by simple execution:

php myphar.phar

This method provides a simple and easy method to create a stub that will run a startup file from the phar archive. In addition, different files can be specified for running the phar archive from the command line versus through a web server. The loader stub also calls Phar::interceptFileFuncs() to allow easy bundling of a PHP application that accesses the file system. If the phar extension is not present, the loader stub will extract the phar archive to a temporary directory and then operate on the files. A shutdown function erases the temporary files on exit.

Parameters

index: Relative path within the phar archive to run if accessed on the command-line
webIndex: Relative path within the phar archive to run if accessed through a web browser

Return Values

Returns a string containing the contents of a customized bootstrap loader (stub) that allows the created Phar archive to work with or without the Phar extension enabled.

Errors/Exceptions

Throws UnexpectedValueException if either parameter is longer than 400 bytes.

Changelog

Version	Description
8.0.0	`index` and `webIndex` are now nullable.
