idate
(PHP 5)
idate — Format a local time/date as integer
설명
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.

선택적인 timestamp 매개변수는 현재 로컬 시간을 기본값으로 가지는 integer 유닉스 타임스탬프입니다. 즉, 기본값은 time() 값입니다.
반환값
Returns an integer.
As idate() always returns an integer and as they can't start with a "0", idate() may return fewer digits than you would expect. See the example below.
오류/예외
모든 날짜/시간 함수 호출은 시간대가 유효하지 않을 때 E_NOTICE를, 시스템 설정이나 TZ 환경 변수를 사용할 때 E_STRICT를 생성합니다. date_default_timezone_set()을 참고하십시오.
변경 기록
| 버전 | 설명 |
|---|---|
| 5.1.0 | Now issues the E_STRICT and E_NOTICE time zone errors. |
