(PHP 5 >= 5.1.0, PHP 7)
date_default_timezone_set — Sets the default timezone used by all date/time functions in a script
$timezoneId
) : booldate_default_timezone_set() sets the default timezone used by all date/time functions.
Notă:
Since PHP 5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a
E_NOTICE
if the timezone isn't valid, and/or aE_WARNING
message if using the system settings or the TZ environment variable.
Instead of using this function to set the default timezone in your script, you can also use the INI setting date.timezone to set the default timezone.
timezoneId
The timezone identifier, like UTC
,
Africa/Lagos
, Asia/Hong_Kong
, or
Europe/Lisbon
. The list of valid identifiers is
available in the Lista zonelor orare susținute.
This function returns false
if the
timezoneId
isn't valid, or true
otherwise.
Example #1 Getting the default timezone
<?php
date_default_timezone_set('America/Los_Angeles');
$script_tz = date_default_timezone_get();
if (strcmp($script_tz, ini_get('date.timezone'))){
echo 'Script timezone differs from ini-set timezone.';
} else {
echo 'Script timezone and ini-set timezone match.';
}
?>
