My query is very long, I don't understand whether my query is correct or not, My knowledge in php is very limited, I try to output using the following php code:

I want to get the correct Y or N under each day(day1,day2,and so on) columns. So far it does not output the desired resultI can provide the table if necessary...
Here is my new query, I want to put -/- and - where the day is Saturday and Sunday or Holiday:
SELECT Students.Name_of_Student, Students.Roll_no, Students.Class, Students.Section, allDays.aDay,
GROUP_CONCAT(IFNULL(attendance.Status, '-') ORDER BY TimePeriod.`time` DESC SEPARATOR '/') AS Status
FROM (SELECT DISTINCT Name_of_Student, Roll_no, Class, Section FROM attendance ) AS Students
CROSS JOIN (SELECT 1 AS aDay UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION
SELECT 10 AS aDay UNION SELECT 11 UNION SELECT 12 UNION SELECT 13 UNION SELECT 14 UNION SELECT 15 UNION SELECT 16 UNION SELECT 17 UNION SELECT 18 UNION SELECT 19 UNION
SELECT 20 AS aDay UNION SELECT 21 UNION SELECT 22 UNION SELECT 23 UNION SELECT 24 UNION SELECT 25 UNION SELECT 26 UNION SELECT 27 UNION SELECT 28 UNION SELECT 29 UNION
SELECT 30 UNION SELECT 31) allDays
CROSS JOIN (SELECT 'Morning' AS `time` UNION SELECT 'Afternoon') TimePeriod
LEFT OUTER JOIN attendance ON Students.Name_of_Student = attendance.Name_of_Student AND allDays.aDay = DAY(`Date`)
AND BINARY TimePeriod.`time` = BINARY attendance.`time` where Date Between '$f' and '$t' and Students.Section='$s' and Students.Class='$c'
GROUP BY Students.Name_of_Student, Students.Roll_no, Students.Section, allDays.aDay
ORDER BY Students.Name_of_Student, allDays.aDay
Rather than trying to get a whole line line that, probably easier to get a row per person per day. Then in your php code you throw a new line when the person changes.
SQL something like this:-
SELECT Students.Name_of_Student, Students.Roll_no, Students.Section, allDays.aDay, attendence.Status
FROM (SELECT DISTINCT Name_of_Student FROM attendence WHERE `Date` BETWEEN '$f' AND '$t') AS Students
CROSS JOIN (
SELECT 1 AS aDay UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION
SELECT 10 AS aDay UNION SELECT 11 UNION SELECT 12 UNION SELECT 13 UNION SELECT 14 UNION SELECT 15 UNION SELECT 16 UNION SELECT 17 UNION SELECT 18 UNION SELECT 19 UNION
SELECT 20 AS aDay UNION SELECT 21 UNION SELECT 22 UNION SELECT 23 UNION SELECT 24 UNION SELECT 25 UNION SELECT 26 UNION SELECT 27 UNION SELECT 28 UNION SELECT 29 UNION
SELECT 30 UNION SELECT 31
) allDays
LEFT OUTER JOIN attendence
ON Students.Name_of_Student = attendence.Name_of_Student AND allDays.aDay = DAY(`Date`)
WHERE `Date` BETWEEN '$f' AND '$t'
This is getting a list of the students (which would be easier if you had a student table) and a list of all the days of the month. Then joining those with a left join against attendence.
Your php would then be something like this (not tested)

EDIT - updated query.
Note I have put the clauses to limit the students within the sub select which gets the list of students. Further the check for dates I have put in the ON clause of the LEFT OUTER JOIN to get the actual attendance. This was even if the student has not attended any classes in that time period they will still appear in the report (just with -/- for each day).
