DateTimeZone::listAbbreviations -- timezone_abbreviations_list — Returns associative array containing dst, offset and the timezone name
Object-oriented style
public static DateTimeZone::listAbbreviations(): array
Procedural style
timezone_abbreviations_list(): array
The returned list of abbreviations includes all historical use of abbreviations, which can lead to correct, but confusing entries. There are also conflicts, as PST is used both in the US and in the Philippines.
The list that this function returns is therefore not suitable for building an array with options to present a choice of timezone to users.
Note:
The data for this function are precompiled for performance reasons, and are not updated when using a newer » timezonedb.
This function has no parameters.
Returns the array of timezone abbreviations.
