wp_load_alloptions() │ WP 2.2.0

Loads into cache all auto-loaded options of WordPress. Retrieves all options of the site.

If there are no auto-loaded options, then load all options.

The label indicating whether the option is auto-loaded is set when adding the option or when updating it in the parameter $autoload:

add_option( $name, $value, $deprecated, $autoload );
// or
update_option( $option_name, $newvalue, $autoload );

This function is called automatically at an early stage of loading WordPress. It loads all options from the wp_options table. Later, when we retrieve an option using get_option(), the option is taken from the cache, not from the database.

The function caches the result of its work, so the first call to the function takes a long time, while all subsequent calls are very fast.

Uses: wp_cache_get(), wp_cache_add()

	[default_category] => 1
	[default_comment_status] => open
	[default_ping_status] => open
	...

#2 Get all transient options without timelimit

$all_options = wp_load_alloptions();
$all_transients  = array();

foreach ( $all_options as $name => $value ) {

	if ( strstr( $name, '_transient' ) ) {
		$all_transients[ $name ] = $value;
	}
}

print_r( $all_transients );
