[wp-hackers] readme.txt: "Requires PHP 5 tag"

[Otto]

Don't rely on users, they're invariably idiots. ;)

Make your plugin smarter instead.

/**
 * plugin_activation_check()
 *
 * Replace "plugin" with the name of your plugin
 */
function plugin_activation_check(){
	if (version_compare(PHP_VERSION, '5.0.0', '<')) {
		deactivate_plugins(basename(__FILE__)); // Deactivate ourself
		wp_die("Sorry, but you can't run this plugin, it requires PHP 5 or higher.");
	}
}
register_activation_hook(__FILE__, 'plugin_activation_check');
