$GLOBALS¶

Changed in version 12.0: The global variable $GLOBALS['TBE_MODULES'] was removed. Setting it has no effect anymore. Use the ModuleProvider instead.

TYPO3_CONF_VARS¶

Path: $GLOBALS
Type: array
Defined: typo3/sysext/core/Configuration/DefaultConfiguration.php
Frontend: yes

TYPO3 configuration array. Please refer to the chapter TYPO3_CONF_VARS where each option is described in detail.

Most values in this array can be accessed through the tool Admin Tools > Settings > Configure Installation-Wide Options.

TCA¶

Path: $GLOBALS
Type: array
Defined: \TYPO3\CMS\Core\Core\Bootstrap::loadExtensionTables()
Frontend: Yes, partly

T3_SERVICES¶

Path: $GLOBALS
Type: array
Defined: \TYPO3\CMS\Core\Core\SystemEnvironmentBuilder::initializeGlobalVariables()
Frontend: Yes

Global registration of services.

TBE_STYLES¶

Deprecated since version 12.3: Migrate to the new configuration setting $GLOBALS['TYPO3_CONF_VARS']['BE']['stylesheets'] which can be set per site or within an extension's ext_localconf.php. For a custom stylesheet of the TYPO3 Admin Panel, it is recommended to use the AdminPanel Module API (available since TYPO3 v9 LTS) where custom CSS and JavaScript files can be registered dynamically.

Path: $GLOBALS
Type: array
Defined: typo3/sysext/core/ext_tables.php
Frontend: (occasionally)

Contains information related to BE skinning.

TSFE¶

Path: $GLOBALS
Type: TypoScriptFrontendController
Defined: typo3/sysext/core/ext_tables.php
Frontend: yes

Contains an instantiation of \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController.

Attention

Directly access $GLOBALS['TSFE'] only as a last resort. It is strongly discouraged if not absolutely necessary.

Provides some public properties and methods which can be used by extensions. The public properties can also be used in TypoScript via TSFE.

More information is available in TSFE.

TYPO3_USER_SETTINGS¶

Path: $GLOBALS
Type: array
Defined: typo3/sysext/setup/ext_tables.php

Defines the form in the User Settings.

PAGES_TYPES¶

Path: $GLOBALS
Type: array
Defined: typo3/sysext/core/ext_tables.php
Frontend: (occasionally)

$GLOBALS['PAGES_TYPES'] defines the various types of pages (doktype) the system can handle and what restrictions may apply to them.

Here you can define which tables are allowed on a certain page types (doktype).

The default configuration applies if the page type is not defined otherwise.

BE_USER¶

Path: $GLOBALS
Type: \TYPO3\CMS\Core\Authentication\BackendUserAuthentication
Defined: \TYPO3\CMS\Core\Core\Bootstrap::initializeBackendUser()
Frontend: (depends)

Backend user object. See Backend user object.

EXEC_TIME¶

Path: $GLOBALS
Type: int
Defined: \TYPO3\CMS\Core\Core\SystemEnvironmentBuilder::initializeGlobalTimeTrackingVariables()
Frontend: yes

Is set to time() so that the rest of the script has a common value for the script execution time.

Note

Should not be used anymore, rather use the DateTime Aspect.

SIM_EXEC_TIME¶

Path: $GLOBALS
Type: int
Defined: \TYPO3\CMS\Core\Core\SystemEnvironmentBuilder::initializeGlobalTimeTrackingVariables()
Frontend: yes

Is set to $GLOBALS['EXEC_TIME'] but can be altered later in the script if we want to simulate another execution-time when selecting from e.g. a database (used in the frontend for preview of future and past dates)

Note

Should not be used anymore, rather use the DateTime Aspect.

LANG¶

Path: $GLOBALS
Type: \TYPO3\CMS\Core\Localization\LanguageService
Defined: is initialized via \TYPO3\CMS\Core\Localization\LanguageServiceFactory
Frontend: no

Attention

It is discouraged to use this variable directly. The LanguageServiceFactory should be used instead to retrieve the LanguageService.

The LanguageService can be used to fetch translations.

More information about retrieving the LanguageService is available in Localization in PHP.

Exploring global variables¶

Many of the global variables described above can be inspected using the module System > Configuration.

Warning

This module is always viewed in the BE context. Variables defined only in the FE context will not be visible there.

Note

This module is purely a browser. It does not let you change values.

It also lets you browse a number of other global arrays as well as values defined in other syntaxes including YAML.
