year % 2 is 0 (i.e. false) if the year is even, and 1 (i.e. true, as is any non-zero value in C) if the year is odd. % is the "modulus" or "remainder" operator.

Good morning all!
I want to know if Im interpreting this if statement below right.
if(((1) || (0)) && (1)){
do stuff;
}
This is saying: if true piped into false, then true, then do stuff. Right?
What does the && stand for?
thanks in advance!

EASTER_DAYS(3) 1 EASTER_DAYS(3)easter_days - Get number of days after March 21 on which Easter falls for a given yearSYNOPSIS
int easter_days ([int $year = date("Y")], [int $method = CAL_EASTER_DEFAULT])
DESCRIPTION
Returns the number of days after March 21 on which Easter falls for a given year. If no year is specified, the current year is assumed.
This function can be used instead of easter_date(3) to calculate Easter for years which fall outside the range of Unix timestamps (i.e.
before 1970 or after 2037).
The date of Easter Day was defined by the Council of Nicaea in AD325 as the Sunday after the first full moon which falls on or after the
Spring Equinox. The Equinox is assumed to always fall on 21st March, so the calculation reduces to determining the date of the full moon
and the date of the following Sunday. The algorithm used here was introduced around the year 532 by Dionysius Exiguus. Under the Julian
Calendar (for years before 1753) a simple 19-year cycle is used to track the phases of the Moon. Under the Gregorian Calendar (for years
after 1753 - devised by Clavius and Lilius, and introduced by Pope Gregory XIII in October 1582, and into Britain and its then colonies in
September 1752) two correction factors are added to make the cycle more accurate.
PARAMETERS
o $year
- The year as a positive number. If omitted, defaults to the current year according to the local time.
o $method
- Allows Easter dates to be calculated based on the Gregorian calendar during the years 1582 - 1752 when set to CAL_EASTER_ROMAN.
See the calendar constants for more valid constants.
RETURN VALUES
The number of days after March 21st that the Easter Sunday is in the given $year.
EXAMPLES
Example #1
easter_days(3) example
<?php
echo easter_days(1999); // 14, i.e. April 4
echo easter_days(1492); // 32, i.e. April 22
echo easter_days(1913); // 2, i.e. March 23
?>
