upgrade.php is a PHP version compatibility library.

• Which makes it an easy solution for using newer features on older PHP installations.
• Most functions are combined into an all-in-one library.
• Emulations for some PHP extensions come as separate scripts.

This is the bugtracker / version control site for upgradephp.

The current project homepage is located at http://include-once.org/p/upgradephp.

Usage

include_once("upgrade.php");

json_encode("this will always work now");

Modules

• gettext.php adds _() and various gettext() features. This extension is commonly used for localizing applications. Unlike other methods this is extremely easy to apply in source code.

• ftp.php reimplements FTP access using plain PHP socket functions.

• ctype.php provides a set of character classification functions.

• mime.php has MIME magic filetype detection functions. It's incomplete however.

• pdo.php is an emulatoion of the PDO database abstraction layer for PHP 4.x and PHP 5.0.

• pspell.php uses the commandline aspell utility to emulate the pspell_*() type of functions for checking for natural language spelling errors.

• bcmath.php for arbitrary precision math functions.

• php40array.php archives the more seldomly used array functions. This has been extracted from the main script, to keep it lean.

• The historic php40.php provides some functions for PHP 4.0 compatibility. Alltough nobody probably still has such old PHP versions running.

Nonstandard

Distributed alongside upgrade.php are a few function collections, which aren't really standard PHP. The author just has been too lazy to instantiat individual project hosting sites.

• http_query.class.php provides HttpRequest funtionality. It is partly compatible to PEAR::HTTPRequest, but mainly in place to later have an emulation for the PHP/PECL http extension and http_* functions.

• input.php is a highly recommended security feature. It wraps the input arrays $_GET, $_POST, $_REQUEST, $_COOKIE, $_SERVER into an object-oriented access layer. This OO access wrapper only allows access to submitted form data and HTTP variables through filter features. In essence this enforces input validation, because raw access is prevented (or at least can be logged).
