Hi guys, I need a regular expression to parse a body of text. Basically assume this that we have text files and each of which contains random text but within the text there would be lines in the following formats - basically they are a format for denoting flight legs.

eg:

13FEB2009 BDR7402 1000 UUBB 1020 UUWW FLT

This line of text is always on one line

The first word is a date in the format DDMMMYYYY

Second word could be of any length and hold alphanumeric characters

third word is the time in format HHMM - its always numeric

fourth word is a location code - its almost always just alphabets but could also be alphanumeric

fifth word is the arrival time in format HHMM - its always numeric

sixth word is a location code - its almost always just alphabets but could also be alphanumeric

Any words which follow on the same line are just definitions

A text file may contain among lots of random text information one or more such lines of text.

I need a way to be able to extract all this information i.e just these lines within a text file and store them with their integral parts separated as mentioned in an associative array so I have something like this:

array('0'=>array('date'=>'', 'time-dept'=>'', 'flightcode'=>'',....))

I'm assuming regular expressions would be in order here. I'm using php for this - would appreciate the help guys :)
