    Convert Month Number to Month Name in a Range

    Hi..

    I need help in getting the 3 Months Name from my table field FromMonth and ToMonth.
    Here is the scenario.

    First, I select FromMonth and ToMonth.
    Ex.
    FromMonth = 5
    ToMonth = 7
    So it means
    FromMonth is May
    ToMonth is July.

    Now I save the MonthNumber to my database:

    table- so_month
    FromMonth = 5
    ToMonth = 7

    Now I need to get the between Months Name from FromMonth to ToMonth which are (May, June, July).

    How does it possible?
    Thank you so much.

    probably the simplest way would be to create an indexed array of month names, e.g.:
    PHP Code:
    $monthNames = array(
      
    => 'January',
      
    'February',
      
    'March',
      
    'April',
      
    'May',
      
    'June',
      
    'July',
      
    'August',
      
    'September',
      
    'October',
      
    'November',
      
    'December'
    ); 
    Then, for example, if you need the name of the 7th month:
    PHP Code:
    echo $monthNames[7];

    Working days is SUM of workingdays of 3 months, I have code for getting the consecutive 3 months but now I got a problem in getting the SUM of working days.

    here is my code for that:


    PHP Code:
    echo "<tr><td>Working Days</td>";
    function 
    monthNames($from$to){
       
    $range=array();
       for(
    $i=$from$i<=$to$i++){
               
    $range[$i]=date('M'mktime(0,0,0,$i));
       }
        return 
    $range;
    }

    $sql "SELECT FromMonth, ToMonth FROM so_month";
    $res mysql_query($sql,$con);

    $row mysql_fetch_assoc($res);
    $FromMonth $row['FromMonth'];
    $ToMonth $row['ToMonth'];
     

    foreach( 
    monthNames($FromMonth$ToMonth) as $month){ echo $month,'<br>';  
    $sql "SELECT MonthName, SUM(WorkingDays) AS WorkingDays FROM working_days WHERE Month_Name = '$month' ORDER BY MonthName";
    $res mysql_query($sql$con);

    $row mysql_fetch_assoc($res);

    $WorkingDays $row['WorkingDays'];

    echo 
    "<td>$WorkingDays</td>";


    but I got this error:

    Apr

    Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in D:\Program Files\xampp\htdocs\MES PROJECT\HalfShellParam.php on line 147
    May

    Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in D:\Program Files\xampp\htdocs\MES PROJECT\HalfShellParam.php on line 147
    Jun

    Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in D:\Program Files\xampp\htdocs\MES PROJECT\HalfShellParam.php on line 147

    Thank you

    One of your queries is failing to process, so add some debug code to find out why:
    PHP Code:
    $res mysql_query($sql);
    if(
    $res == false) {
       throw new 
    Exception("Query failed: ".mysql_error()."\n$sql");

    Hi..

    I resolved it now using thid code:

    PHP Code:
    //-----Computation of Working Days---//
    $sql "SELECT FromMonth, ToMonth FROM so_month";
    $res mysql_query($sql,$con);

    $row mysql_fetch_assoc($res);
    $FromMonth $row['FromMonth'];
    $ToMonth $row['ToMonth'];

    function 
    monthNames($from$to){
       
    $range=array();
       for(
    $i=$from$i<=$to$i++){
               
    $range[$i]=date('M'mktime(0,0,0,$i));
       }
        return 
    $range;
    }
     
    $month_ implode("' ', ",monthNames($FromMonth,$ToMonth));

    foreach( 
    monthNames($FromMonth$ToMonth) as $month){ 
    $sql "SELECT MonthName, SUM(WorkingDays) AS WorkingDays FROM working_days WHERE MonthName IN ('$month') GROUP BY MonthName";
    $res mysql_query($sql$con);
    $SumWorkingDays 0
    while(
    $row mysql_fetch_array($res)){

     
    $WorkingDays+=(int)$row['WorkingDays'];
    $SumWorkingDays += $WorkingDays;

    }

    Thank you
