> ColumnA ColumnB

> R ABC company
> ABC company
> ABC company
> ABC company
> O XYZ company
> XYZ company
> XYZ company
> XYZ company

>
> ColumnA ColumnB
>
> R ABC company
> R ABC company
> R ABC company
> R ABC company
> O XYZ company
> O XYZ company
> O XYZ company
> O XYZ company
>
> Is this possible. What I've got so far to print out the file:
>
> $lines = file('test2.csv');
>
$category = '';
> // Loop through our array, and show line and numbers too.
> foreach ($lines as $line_num => $line) {
> echo "Line #<b>{$line_num}</b> : " . $line . "<br />\n";
//Assuming it's the FIRST character of each line that has space or category:
//Check first character:
if ($line[0] != ' ' && $line[0] != "\t"){
$category = $line[0];
}
echo "$category\t", trim(substr($line, 1)), "<br />\n";
