My knowledge in PHP is starting to fade away, so I need help with some various smaller scripts. 2 for data handling, and one for an email function online:
1) Sort the data in a text file, semi-colon delimited. A line in the source file is (1020102;163253;131.74000) where the first column is the date, the second is time in hhmmss and the last is a price. This data shall be sorted first by date then by time. Then it shall check if two rows are the same, and delete one of them.
2) Based on the sorted file above, that info shall be rewritten as (date time;x;x;x;x) where x will be replaced with other info.
3) Third script is an update to an php webpage, where we first need to first assign some values to global variables, and then on another webpage read these and send two emails to two different email adresses.
For an experiences php programmer the above scripts should take more than 1-2 hours. It's therefore important that the bidder can invoice us.
EDIT: The last row should be that the project SHOULDN'T take more than 1-2 hours.
