add data to text file?

[muppet77]

is there a php solution that will take

the raw data from one file and paste it

into another text file?

 

I have a master file and a download

file that always starts at quarter past

midnight . this data needs to be

pasted into the master file, in the

correct place , possibly overlapping

and replacing data that already exists.

 

the length of the download file will

vary but will always start at 00. 15

the two files are

 

www.maidenerleghweather.com/download.txt and also

www.maidenerleghweather.com/master.txt

 

any help appreciated .

Read data from one file

$dfile = "download.txt";
$dopr = fopen($dfile, 'r');
$collectdata= fread($dopr, 50000);
fclose($dopr);

write data into another file

$mfile = "master.txt";
$mopr = fopen($mfile, 'w') or die("could not open file");
fwrite($mopr, $collectdata);
fclose($mopr);

thanks, but will that write the data to the correct place?

 

eg in master you may have rows with data in them

1...

2...

3...

4...

5...

 

and in the download you may have

3...

4...

5...

6...

7...

 

 

i would like the 6th  and 7th row to be added and not the 3rd,4th or 5th as it is already present.

it is a bit difficult to implement with file management system. you need to use explode like functions and lots of coding is needed and you may get ambiguous results . alternatively you can do it easily with by using database even if writing to the file is important for you you can do it in short with the help of mysql or mssql database.

how about this as an idea but not sure how I'd code it...

 

look at the master file and get the last date and time.

 

loop through the download file.

 

if date and time is later than these values then write that line to the master file.

 

any ideas?

well this is my unsuccessful attempt so far.

 

what's going wrong?
