$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]¶

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘fileCreateMask’]¶

fileCreateMask¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	0664

File mode mask for Unix file systems (when files are uploaded/created).

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘folderCreateMask’]¶

folderCreateMask¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	2775

As above, but for folders.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘createGroup’]¶

createGroup¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘’

Group for newly created files and folders (Unix only). Group ownership can be changed on Unix file systems (see above). Set this if you want to change the group ownership of created files/folders to a specific group.

This makes sense in all cases where the webserver is running with a different user/group as you do. Create a new group on your system and add you and the webserver user to the group. Now you can safely set the last bit in fileCreateMask/folderCreateMask to 0 (for example 770). Important: The user who is running your webserver needs to be a member of the group you specify here! Otherwise you might get some error messages.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘sitename’]¶

sitename¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘TYPO3’

Name of the base-site.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘encryptionKey’]¶

encryptionKey¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘’

This is a “salt” used for various kinds of encryption, CRC checksums and validations. You can enter any rubbish string here but try to keep it secret. You should notice that a change to this value might invalidate temporary information, URLs etc. At least, clear all cache if you change this so any such information can be rebuilt with the new key.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘cookieDomain’]¶

cookieDomain¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘’

Restricts the domain name for FE and BE session cookies. When setting the value to “.example.org” (replace example.org with your domain!), login sessions will be shared across subdomains. Alternatively, if you have more than one domain with sub-domains, you can set the value to a regular expression to match against the domain of the HTTP request.

The result of the match is used as the domain for the cookie. for example : php:/\.(example1|example2)\.com$/ or /\.(example1\.com)|(example2\.net)$/. Separate domains for FE and BE can be set using $TYPO3_CONF_VARS[FE][cookieDomain] and $TYPO3_CONF_VARS[BE][cookieDomain] respectively.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘trustedHostsPattern’]¶

trustedHostsPattern¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘SERVER_NAME’

Regular expression pattern that matches all allowed hostnames (including their ports) of this TYPO3 installation, or the string SERVER_NAME (default).

The default value SERVER_NAME checks if the HTTP Host header equals the SERVER_NAME and SERVER_PORT. This is secure in correctly configured hosting environments and does not need further configuration. If you cannot change your hosting environment, you can enter a regular expression here.

Examples:

.*\.example\.org matches all hosts that end with .example.org with all corresponding subdomains.

.*\.example\.(org|com) matches all hostnames with subdomains from .example.org and .example.com.

Be aware that HTTP Host header may also contain a port. If your installation

runs on a specific port, you need to explicitly allow this in your pattern,

for example example\.org:88 allows only example.org:88, not example.org. To disable this check completely

(not recommended because it is insecure) you can use .* as pattern.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘devIPmask’]¶

devIPmask¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘127.0.0.1,::1’

Defines a list of IP addresses which will allow development-output to display. The debug() function will use this as a filter. See the function \TYPO3\CMS\Core\Utility\GeneralUtilitycmpIP() for details on syntax. Setting this to blank value will deny all. Setting to “*” will allow all.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘ddmmyy’]¶

ddmmyy¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘loginCopyrightWarrantyURL’]¶

loginCopyrightWarrantyURL¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘’

Example: perl=/usr/bin/perl,unzip=/usr/local/bin/unzip

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘setMemoryLimit’]¶

setMemoryLimit¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	int
Default:	0

Memory limit in MB: If more than 16, TYPO3 will try to use ini_set() to set the memory limit of PHP to the value. This works only if the function ini_set() is not disabled by your sysadmin.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘phpTimeZone’]¶

phpTimeZone¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	text
Default:	‘’

If blank, a valid fallback will be searched for by PHP (php.inis date.timezone setting, server defaults, etc); and if no fallback is found, the value of “UTC” is used instead.

$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘UTF8filesystem’]¶

UTF8filesystem¶

Path:	$GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’]
Type:	bool
Default:	false

If TRUE then TYPO3 uses utf-8 to store file names. This allows for accented latin letters as well as any other non-latin characters like Cyrillic and Chinese.

IMPORTANT This requires a UTF-8 compatible locale in order to work. Otherwise problems with filenames containing special characters will occur. See [SYS][systemLocale] and php function setlocale().

AllowedValues:

`-1`	TYPO3 does not touch the PHP setting. If [SYS][devIPmask] matches the users IP address, the configured [SYS][debugExceptionHandler] is used instead of the [SYS][productionExceptionHandler] to handle exceptions.

0: Live: Do not display any PHP error message. Sets display_errors=0. Overrides the value of [SYS][exceptionalErrors] and sets it to 0 (= no errors are turned into exceptions). The configured [SYS][productionExceptionHandler] is used as exception handler.
1: Debug: Display error messages with the registered [SYS][errorHandler]. Sets display_errors=1. The configured [SYS][debugExceptionHandler] is used as exception handler.

Configures whether PHP errors or Exceptions should be displayed, effectively setting the PHP option display_errors during runtime.
