    How to check entered time range is in a given time range using php

    My question is how to add time range validations. user can add a 'task1' between 8.00am to 10.00 am so the time range is between 8.00am and 10.00am. I need to prevent user by entering next task between above time range. Maybe 'task2' start time is 8.30am and end time is 9.30am. Above time range is queried form database table. I tried to do that by using between clause, but at some point I stucked. so need your help. so can i do that? I tried searching all over and couldn't find any solution for that. hope you can my question you.

    query the database values from here Get the Previous values from Database
    PHP Code:
    $start=$val['starttime']; $end=$val['end']; 
    then get what user has entered.
    PHP Code:
    $start_time=$_POST['start_time']; $end_time=$_POST['end_time']; 
    this is the between that i tried.
    PHP Code:
    if((($start_time<=$start)&&($start>=$endtime))&&(($start_time<=$end)&& ($end>=$end_time)) {      echo "<script>location.replace(\"test.php?msg=cannot enter another task in  the same time period\");</script>" ; } 
    I just need to post an error message to the user

    Thanks in Advance...need support
