t()

SimpleSAML\Locale\Translate::t	(		$tag,
			$replacements = array(),
			$fallbackdefault = true,
			$oldreplacements = array(),
			$striptags = false
	)

Translate a tag into the current language, with a fallback to english.

This function is used to look up a translation tag in dictionaries, and return the translation into the current language. If no translation into the current language can be found, english will be tried, and if that fails, placeholder text will be returned.

An array can be passed as the tag. In that case, the array will be assumed to be on the form (language => text), and will be used as the source of translations.

This function can also do replacements into the translated tag. It will search the translated tag for the keys provided in $replacements, and replace any found occurrences with the value of the key.

Parameters

string | array	$tag	A tag name for the translation which should be looked up, or an array with (language => text) mappings. The array version will go away in 2.0
array	$replacements	An associative array of keys that should be replaced with values in the translated string.
boolean	$fallbackdefault	Default translation to use as a fallback if no valid translation was found.

Deprecated:

Not used in twig, gettext

Returns

string The translated tag, or a placeholder value if the tag wasn't found.
