Hi all,
Can anyone provide me any checklists or a list of steps I should follow before executing my scripts.
Could also tell me if there are any other standards to be followed while shell programming like naming conventions for variables etc.
Your help would be much appreciated.

current
CURRENT(3) 1 CURRENT(3)current - Return the current element in an arraySYNOPSIS
mixed current (array &$array)
DESCRIPTION
Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.
PARAMETERS
o $array
- The array.
RETURN VALUES
The current(3) function simply returns the value of the array element that's currently being pointed to by the internal pointer. It does
not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, current(3)
returns FALSE.
Warning
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
Booleans for more information. Use the === operator for testing the return value of this function.
EXAMPLES
Example #1
Example use of current(3) and friends
<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport); // $mode = 'bike';
$mode = current($transport); // $mode = 'bike';
$mode = prev($transport); // $mode = 'foot';
$mode = end($transport); // $mode = 'plane';
$mode = current($transport); // $mode = 'plane';
$arr = array();
var_dump(current($arr)); // bool(false)
$arr = array(array());
var_dump(current($arr)); // array(0) { }
?>
NOTES
Note
You won't be able to distinguish the end of an array from a boolean FALSE element. To properly traverse an array which may contain
FALSE elements, see the each(3) function.
SEE ALSO end(3), key(3), each(3), prev(3), reset(3), next(3).
