Saving data onto a txt file and reading it with PHP

[tech_support]

Hi,

I have been asked to make a booking sheet for rooms in my school.
How do you say create a file with the date (with PHP) (20/09/06 or something) like booking_20.09.06.txt

And the txt file will be like:

[c1]
pd1=0
pd2=1

[c4]
pd1=0
pd2=1

And then if you plan to book the room (C1) you will submit a form saying:

Room: C1
Time: PD1
Name: John Smith

and if the text file says: "pd1=1" it will say "Sorry, booked." and if it says "pd1=0" it will change to 1 and say "Successfully booked."

and every day to will check to see if the text file has been created and if not create a new one.

And then if you want you can click "Times Booked" and it will show you the list of bookings like

PD1 = Booked
PD2 = Not Booked

Hope you don't get confused

Anyone know the solution?

Thanks,

Peter

<?php
$a=date("d").".". date("m").".".date("y");
$a="booking_".$a.".txt";

if (!file_exist($a)){
$ac=fopen($a,"w") or die("There is Problem");

//Put what do you want

fclose($ac);
}else
{

//Put what do you want

}
?>

This isn't homework, is it?

When using dates in file names, use yyyy-mm-dd. This is a naturally sorting format, which makes managing the files easier.

And the txt file will be like:

[c1]
pd1=0
pd2=1

[c4]
pd1=0
pd2=1

Must you use a text file? Must it use that format? Can you use a database, XML, or any other format?

And then if you plan to book the room (C1) you will submit a form saying:

Room: C1
Time: PD1
Name: John Smith

Wouldn't you want to get the name of the booker back? If so, where did you plan on storing that?

No it isin't - It's just credit for me from the school - And I DON'T get paid

OK.

I'm open to any other format except MySQL cause I can't get my MySQL working properly

Yes I would, and it will be on the same text file.


Security is not a pirority. The only thing they'll be stealing is when the teacher has booked the room.

date("d.m.y") works too, instead of three date statements and "." strings.

Yeah, it does so

(Wow... a response in 8 minutes.)

While I was working with this thing it came to this error message:

Warning: fopen(............) [function.fopen]: failed to open stream: No such file or directory in ............. on line 13

Can I change it to something like this:

Cannot find file.

[djr33]

if (!(@file_exist($a))){
$ac=@fopen($a,"w") or die("custom error here");

//Put what do you want

@fclose($ac);

Using @function() makes it not return an error.
Or you could just turn off error reporting all together.

However, using @function() or die('error') is good, so you do know if/where it failed.

Using a database (any, it doesn't have to be MySQL) would be ideal. It would make concurrency (assuming that's a potential issue) and querying much simpler. If you're using PHP 5, SQLite may be an option, though finding out why MySQL isn't working would be a sensible thing to do, anyway.

date("d.m.y") works too, instead of three date statements and "." strings.

Yes, though the format's still wrong.

'bookings-' . date('Y.m.d')

Oh, I wasn't worried about order. I'm just saying you can do it all in one (and was copying the order above, for continuity).
