You need to put [ code] [/code ] tags around your examples so the formatting doesn't get lost.
I'd assume that the file contains just raw data and you want fixed width output. The printf command is probably what you want to use perhaps something like:

mysqli_field_seek
MYSQLI_FIELD_SEEK(3) 1 MYSQLI_FIELD_SEEK(3)mysqli_result::field_seek - Set result pointer to a specified field offset
Object oriented style
SYNOPSIS
bool mysqli_result::field_seek (int $fieldnr)
DESCRIPTION
Procedural style
bool mysqli_field_seek (mysqli_result $result, int $fieldnr)
Sets the field cursor to the given offset. The next call to mysqli_fetch_field(3) will retrieve the field definition of the column associ-
ated with that offset.
Note
To seek to the beginning of a row, pass an offset value of zero.
PARAMETERS
o $
result -Procedural style only: A result set identifier returned by mysqli_query(3), mysqli_store_result(3) or
mysqli_use_result(3).
o $fieldnr
- The field number. This value must be in the range from 0 to number of fields - 1.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for 2nd column */
$result->field_seek(1);
$finfo = $result->fetch_field();
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
$result->close();
}
/* close connection */
$mysqli->close();
?>
Example #2
Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = mysqli_query($link, $query)) {
/* Get field information for 2nd column */
mysqli_field_seek($result, 1);
$finfo = mysqli_fetch_field($result);
printf("Name: %s
", $finfo->name);
printf("Table: %s
", $finfo->table);
printf("max. Len: %d
", $finfo->max_length);
printf("Flags: %d
", $finfo->flags);
printf("Type: %d
", $finfo->type);
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
Name: SurfaceArea
Table: Country
max. Len: 10
Flags: 32769
Type: 4
