Working with files

Anon

I need to access a file to get information that I need in my PHP-script.
The content of the file will be something like this:

#A B C
12 16 17
16 11 10
12 44 12
14 23 67
15 23 34

How can I access the file, and for example add all the A's, all the B's and all the C's ?

If the file format is always going to be the same the best way is probably:

$filearray = file( "filename" );
foreach ( $filearray as $fileline )
{
$filedata = explode( " ", $fileline);
$file_a = filedata[0];
$file_b = filedata[1];
$file_c = filedata[2];
}

if you want totals then do:

$file_a = 0;
$file_b = 0;
$file_c = 0;
$filearray = file( "filename" );
foreach ( $filearray as $fileline )
{
$filedata = explode( " ", $fileline);
$file_a = $file_a + filedata[0];
$file_b = $file_b + filedata[1];
$file_c = $file_c + filedata[2];
}

Hope that helps
