Returns a number formatted according to the given format string using the given integer timestamp or the current local time if no timestamp is given. In other words, timestamp is optional and defaults to the value of time.
Unlike the function date, idate accepts just one char in the format parameter.
The following characters are recognized in the format parameter string
format character Description B Swatch Beat/Internet Time d Day of the month h Hour (12 hour format) H Hour (24 hour format) i Minutes I (uppercase i) returns 1 if DST is activated, 0 otherwise L (uppercase l) returns 1 for leap year, 0 otherwise m Month number N ISO-8601 day of the week (1 for Monday through 7 for Sunday) o ISO-8601 year (4 digits) s Seconds t Days in current month U Seconds since the Unix Epoch - January 1 1970 00:00:00 UTC - this is the same as time w Day of the week (0 on Sunday) W ISO-8601 week number of year, weeks starting on Monday y Year (1 or 2 digits - check note below) Y Year (4 digits) z Day of the year Z Timezone offset in seconds
The optional timestamp parameter is an int Unix timestamp that defaults to the current local time if timestamp is omitted or null. In other words, it defaults to the value of time.
Returns an int on success, or false on failure.
As idate always returns an int and as they can't start with a "0", idate may return fewer digits than you would expect. See the example below.
Exceptions and Errors
Every call to a date/time function will generate a E_WARNING if the time zone is not valid. See also date_default_timezone_set
