    Greetings!

    I have a need to automatically switch out some field names on the 1st day of the month.  Right now I'm having to upload new edited files every month.  This has become a maintenance nightmare.

    Below is the coding that defines the dates;

      $lastmonth = date('m/y', mktime(0, 0, 0, date("m")-1 , date("d") , date("y")));
      $lastyear = date('m/y', mktime(0, 0, 0, date("m") , date("d") , date("y")-1));
      $lastyear_plus1_month = date('m/y', mktime(0, 0, 0, date("m")+1 , date("d") , date("y")-1));

    Below is the Array for EZPDF to generate my printout data.

      $table[] = array(
              "$lastmonth"=>$row["Julunits"],
              "$lastyear"=>$row["Augunits"],
              "$lastyear_plus1_month"=>$row["Sepunits"]);

    I need to switch out the ["???units"] for each line to accurately grab the right fields from my sql table.
    There are only 12 fields:  Janunits, Febunits, Marunits, Aprunits, Mayunits, Jununits, Julunits, Augunits, Sepunits, Octunits, Novunits, Decunits.

    Any suggestions how I should go about doing this?

    Thank you in advance for you assistance.

    Tom

      Try something like this:

        $rowTitle = array(
          1=>'Janunits',
          2=>'Febunits',
          3=>'Marunits',
          4=>'Aprunits',
          5=>'Mayunits',
          6=>'Jununits',
          7=>'Julunits',
          8=>'Augunits',
          9=>'Sepunits',
          10=>'Octunits',
          11=>'Novunits',
          12=>'Decunits');
       
        $curMo = date("n"); 
        if($curMo==1){
          $lastMo= 12;
          $nextMo = $curMo+1;}
        else{
          $lastMo = $curMo-1;
          $nextMo = ($curMo+1)%12;}
       
        $table[] = array(
          "$lastmonth"=>$row[$rowTitle[$lastMo]],
          "$lastyear"=>$row[$rowTitle[$curMo]],
          "$lastyear_plus1_month"=>$row[$rowTitle[$nextMo]]);

        Change This:
        $curMo = date("n"); 
        ...
        $nextMo = ($curMo+1)%12;}

        To This:
        $curMo = date("n"); 
        if($curMo==1){
        $lastMo= 12;
        $nextMo = $curMo+1;}
        elseif($curMo==12){
        $lastMo = $curMo-1;
        $nextMo = 1;}
        else{
        $lastMo = $curMo-1;
        $nextMo = $curMo+1;}
