Finding data in file using PHP

[computerzworld]

Hello,
I am having one txt file which stores the values in tab separated format which user have entered through form. In this form I have date field and I want to search the data for particular date range. Lets say for month march. How can I search within file for the data within particular date range? Is there any function in php that is used to search? Please help me. Thanks in advance.

[man]fgetcsv[/man] will read and identify the fields based on the delimiter you specify, returning each row/record as an array. Then you have to do some programming to look through those arrays for whatever matches your criteria.
