About:
The upgrade.php script provides PHP backwards compatibility. It does so by automatically defining workalikes for more recently introduced PHP 5.2 or 6.0 core functions when run in an older interpreter version (like 4.1). This allows developers or projects to safely use the more advanced features of PHP while still supporting most applications that run on outdated servers. It emulates over 100 core functions and the complete FTP, ctype, GETTEXT, and mime_magic extensions, and comes with reasonable emulations for PDO, bcmath, ODBC, and the FILTER extension.

Release focus: Major feature enhancements

Changes:
This release includes PDO emulation for PHP 4.x. This new unified PHP5 standard database interface prevents SQL injection exploits if you use its prepared statements instead of error-prone string concatenation and manual escaping. Other changes include more detailed phpDoc-style comments in the main script, and file_put_contents() support for the file locking flag. The emulated json_decode() function now supports Unicode escapes and still remains five times faster than JSON.php or the Zend_Framework decoder.

[»] PEAR::PHP_Compat
by milky - Sep 24th 2004 06:14:25

There is an alternative to the "upgrade.php" script, that already existed for a longer time. You can find it under http://pear.php.net/package/PHP_Compat and it is sometimes already installed on servers.

The emulation functions of PHP_Compat are often a bit cleaner and behave more (Warning messages) like the native ones would. It is suddenly also not complete yet, but both projects can be used in conjuction easily.
