sorry still a little confused.

so the sequence is:
1. load file1, field1 into arr until FNR==NR
2. perform the match condition i.e $3 in arr

at this point my array still contains the value of field 1, are we saying this then gets replaced with the value of field2?

good tip Smilie

IntlDateFormatter::localtime - Parse string to a field-based time value

	Object oriented style

SYNOPSIS
public array IntlDateFormatter::localtime (string $value, [int &$position]) DESCRIPTION
Procedural style array datefmt_localtime (IntlDateFormatter $fmt, string $value, [int &$position]) Converts string $value to a field-based time value ( an array of various fields), starting at $parse_pos and consuming as much of the input value as possible. PARAMETERS
o $fmt - The formatter resource o $value - string to convert to a time o $position - Position at which to start the parsing in $value (zero-based). If no error occurs before $value is consumed, $parse_pos will contain -1 otherwise it will contain the position at which parsing ended . If $parse_pos > strlen($value), the parse fails immedi- ately. RETURN VALUES
Localtime compatible array of integers : contains 24 hour clock value in tm_hour field EXAMPLES
Example #1 datefmt_localtime(3) example <?php $fmt = datefmt_create( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); $arr = datefmt_localtime($fmt, 'Wednesday, December 31, 1969 4:00:00 PM PT', 0); echo 'First parsed output is '; if ($arr) { foreach ($arr as $key => $value) { echo "$key : $value , "; } } ?> Example #2 OO example <?php $fmt = new IntlDateFormatter( 'en_US', IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'America/Los_Angeles', IntlDateFormatter::GREGORIAN ); $arr = $fmt->localtime('Wednesday, December 31, 1969 4:00:00 PM PT', 0); echo 'First parsed output is '; if ($arr) { foreach ($arr as $key => $value) { echo "$key : $value , "; } } ?> The above example will output: First parsed output is tm_sec : 0 , tm_min : 0 , tm_hour : 16 , tm_year : 1969 , tm_mday : 31 , tm_wday : 4 , tm_yday : 365 , tm_mon : 11 , tm_isdst : 0 , SEE ALSO
