Note that PHP 5.x releases use a different >build system and are automatically updated to the latest versions of PEAR. >If you find that PHP 4.3.x has out-of-date versions of packages, or no longer works, then >please report that the windows bundle of PEAR is out of date to pear-dev@lists.php.net Well it's up to PHP 5.3.5, but when I try to install PEAR I get: C:\>cd php C:\PHP>go-pear.bat PHP Deprecated: Directive 'register_globals' is deprecated in PHP 5.3 and great er in Unknown on line 0 Deprecated: Directive 'register_globals' is deprecated in PHP 5.3 and greater in Unknown on line 0 phar "C:\PHP\PEAR\go-pear.phar" does not have a signaturePHP Warning: require_o nce(phar://go-pear.phar/index.php): failed to open stream: phar error: invalid u rl or non-existent phar "phar://go-pear.phar/index.php" in C:\PHP\PEAR\go-pear.p har on line 1236 Warning: require_once(phar://go-pear.phar/index.php): failed to open stream: pha r error: invalid url or non-existent phar "phar://go-pear.phar/index.php" in C:\ PHP\PEAR\go-pear.phar on line 1236 Press any key to continue . . .
