What would this do? if the file that has the proper column/row structure is called "original.1D" and the one-column file that has the proper integers is called "onecolumn.1D" then how would this code be written? which input is "file"?
Thanks

What's MATLAB? What does it have to do with shell scripting?
[/QUOTE]
What I meant is that I know in the programming language Matlab when it reads a text file it reads it one word at a time and the word that its on can be used as a variable and has an assigned name. Then theres another command that goes to the next word of the file so that it can go through each word in a file, do something with it, and move onto the next word. Thats what I want to do.
I want to go through the onecolumn file integer by integer (while at the same time going through the other file integer by integer) and switch the onecolumn integer into the integer of the multicolumn file one word at a time.

pdostatement.fetchcolumn
PDOSTATEMENT.FETCHCOLUMN(3) 1 PDOSTATEMENT.FETCHCOLUMN(3)PDOStatement::fetchColumn - Returns a single column from the next row of a result set
SYNOPSIS
public mixed PDOStatement::fetchColumn ([int $column_number])
DESCRIPTION
Returns a single column from the next row of a result set or FALSE if there are no more rows.
Note
PDOStatement.fetchColumn(3) should not be used to retrieve boolean columns, as it is impossible to distinguish a value of FALSE from
there being no more rows to retrieve. Use PDOStatement.fetch(3) instead.
PARAMETERS
o $column_number
- 0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement.fetchColumn(3) fetches
the first column.
RETURN VALUES PDOStatement.fetchColumn(3) returns a single column in the next row of a result set.
Warning
There is no way to return another column from the same row if you use PDOStatement.fetchColumn(3) to retrieve data.
EXAMPLES
Example #1
Return first column of the next row
<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
print("Fetch the first column from the first row in the result set:
");
$result = $sth->fetchColumn();
print("name = $result
");
print("Fetch the second column from the second row in the result set:
");
$result = $sth->fetchColumn(1);
print("colour = $result
");
?>
The above example will output:
Fetch the first column from the first row in the result set:
name = lemon
Fetch the second column from the second row in the result set:
colour = red
