Method Description
checkdate ( int month, int day, int year ) : bool

Returns TRUE if the date given is valid; otherwise returns FALSE. Checks the validity of the date formed by the arguments.

A date is considered valid if: year is between 1 and 32767 inclusive month is between 1 and 12 inclusive day is within the allowed number of days for the given month. Leap years are taken into consideration.

date ( Context ctx, string format ) : string

Returns a string formatted according to the given format string using the current local time.
date ( Context ctx, string format, int timestamp ) : string

Returns a string formatted according to the given format string using the given integer timestamp.

Returns an associative array containing the date information of the current local time.
getdate ( Context ctx, int timestamp ) : PhpArray

Returns an associative array containing the date information of the timestamp.
gettimeofday ( Context ctx ) : PhpArray

Gets time information.

It returns PhpArray containing the following 4 entries: "sec"Unix timestamp (seconds since the Unix Epoch) "usec"microseconds "minuteswest"minutes west of Greenwich (doesn't take daylight savings time in consideration) "dsttime"type of DST correction (+1 or 0, determined only by the current time zone not by the time)

gettimeofday ( Context ctx, bool returnDouble ) : object
gmdate ( string format ) : string

Identical to the date() function except that the time returned is Greenwich Mean Time (GMT)

Returns a part of current time.
idate ( Context ctx, string format, int timestamp ) : int

Returns a part of a specified timestamp.
localtime ( Context ctx ) : PhpArray

The localtime() function returns an array identical to that of the structure returned by the C function call. Current time is used, regular numericaly indexed array is returned.
localtime ( Context ctx, int timestamp ) : PhpArray

The localtime() function returns an array identical to that of the structure returned by the C function call. Time specified by the parameter timestamp is used, regular numericaly indexed array is returned.
localtime ( Context ctx, int timestamp, bool returnAssociative ) : PhpArray

The localtime() function returns an array identical to that of the structure returned by the C function call. The first argument to localtime() is the timestamp. The second argument to the localtime() is the isAssociative, if this is set to false than the array is returned as a regular, numerically indexed array. If the argument is set to true then localtime() is an associative array containing all the different elements of the structure returned by the C function call to localtime.

Returned array contains these elements if isAssociative is set to true: "tm_sec"seconds "tm_min"minutes "tm_hour"hour "tm_mday"day of the month "tm_mon"month of the year, starting with 0 for January "tm_year"Years since 1900 "tm_wday"Day of the week "tm_yday"Day of the year "tm_isdst"Is daylight savings time in effect
