The localtime() function returns an array identical to that of the structure returned by the C function call.
The optional timestamp
parameter is an integer Unix timestamp that defaults to the current local time if a timestamp
is not given. In other words, it defaults to the value of time().
If set to FALSE
or not supplied then the array is returned as a regular, numerically indexed array. If the argument is set to TRUE
then localtime() returns an associative array containing all the different elements of the structure returned by the C function call to localtime. The names of the different keys of the associative array are as follows:
- "tm_sec" - seconds, 0 to 59
- "tm_min" - minutes, 0 to 59
- "tm_hour" - hours, 0 to 23
- "tm_mday" - day of the month, 1 to 31
- "tm_mon" - month of the year, 0 (Jan) to 11 (Dec)
- "tm_year" - years since 1900
- "tm_wday" - day of the week, 0 (Sun) to 6 (Sat)
- "tm_yday" - day of the year, 0 to 365
- "tm_isdst" - is daylight savings time in effect? Positive if yes, 0 if not, negative if unknown.
Every call to a date/time function will generate a E_NOTICE
if the time zone is not valid, and/or a E_STRICT
or E_WARNING
message if using the system settings or the TZ environment variable. See also date_default_timezone_set()
Now issues the E_STRICT
and E_NOTICE
time zone errors.
<?php $localtime = localtime(); $localtime_assoc = localtime(time(), true); print_r($localtime); print_r($localtime_assoc); ?>
The above example will output something similar to:
Array ( [0] => 24 [1] => 3 [2] => 19 [3] => 3 [4] => 3 [5] => 105 [6] => 0 [7] => 92 [8] => 1 ) Array ( [tm_sec] => 24 [tm_min] => 3 [tm_hour] => 19 [tm_mday] => 3 [tm_mon] => 3 [tm_year] => 105 [tm_wday] => 0 [tm_yday] => 92 [tm_isdst] => 1 )
