The below program will print 4 fields out of 6. Its may not be efficient as it goes through a lot of loops. Or if you have Perl's Text::CSV module installed, you may try that too.

array_splice
ARRAY_SPLICE(3) 1 ARRAY_SPLICE(3)array_splice - Remove a portion of the array and replace it with something elseSYNOPSIS
array array_splice (array &$input, int $offset, [int $length], [mixed $replacement = array()])
DESCRIPTION
Removes the elements designated by $offset and $length from the $input array, and replaces them with the elements of the $replacement
array, if supplied.
Note that numeric keys in $input are not preserved.
Note
If $replacement is not an array, it will be typecast to one (i.e. (array) $parameter). This may result in unexpected behavior when
using an object or NULL$replacement.
PARAMETERS
o $input
- The input array.
o $offset
- If $offset is positive then the start of removed portion is at that offset from the beginning of the $input array. If $offset is
negative then it starts that far from the end of the $input array.
o $length
- If $length is omitted, removes everything from $offset to the end of the array. If $length is specified and is positive, then
that many elements will be removed. If $length is specified and is negative then the end of the removed portion will be that many
elements from the end of the array. If $length is specified and is zero, no elements will be removed. Tip: to remove everything
from $offset to the end of the array when $replacement is also specified, use count($input) for $length.
o $replacement
- If $replacement array is specified, then the removed elements are replaced with elements from this array. If $offset and
$length are such that nothing is removed, then the elements from the $replacement array are inserted in the place specified by the
$offset. Note that keys in replacement array are not preserved. If $replacement is just one element it is not necessary to put
array() around it, unless the element is an array itself, an object or NULL.
RETURN VALUES
Returns the array consisting of the extracted elements.
EXAMPLES
Example #1
array_splice(3) examples
<?php
$input = array("red", "green", "blue", "yellow");
array_splice($input, 2);
// $input is now array("red", "green")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, -1);
// $input is now array("red", "yellow")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, count($input), "orange");
// $input is now array("red", "orange")
$input = array("red", "green", "blue", "yellow");
array_splice($input, -1, 1, array("black", "maroon"));
// $input is now array("red", "green",
// "blue", "black", "maroon")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 3, 0, "purple");
// $input is now array("red", "green",
// "blue", "purple", "yellow");
?>
Example #2
array_splice(3) examples
The following statements change the values of $input the same way:
<?php
array_push($input, $x, $y);
array_splice($input, count($input), 0, array($x, $y));
array_pop($input);
array_splice($input, -1);
array_shift($input);
array_splice($input, 0, 1);
array_unshift($input, $x, $y);
array_splice($input, 0, 0, array($x, $y));
$input[$x] = $y; // for arrays where key equals offset
array_splice($input, $x, 1, $y);
?>
