How to search a CSV file with php by checking if a date falls between 2 ranges -

i made previous post vague. i've done lot of research , think can more specific.

while (!feof($file_handle))  {     $loansinfo = fgetcsv($file_handle);     // make sure check data game posted     if($loansinfo[0]==$id) {          $referencedate = $wanteddate;         $fromdate = "$loansinfo[5]";         $todate = "$loansinfo[6]";         // convert dates timestamps (strings integers)         $referencetimestamp = strtotime( $referencedate );         $fromtimestamp = strtotime( $fromdate );         $totimestamp = strtotime( $todate );         $isbetween = $referencetimestamp >= $fromtimestamp , $referencetimestamp <= $totimestamp;         //refuse booking             echo('<script type="text/javascript">alert("game booked");</script>');         exit;     } } // otherwise execute save code 

problem is, 'game booked'. why?

sample csv file data requested:

id, gamename,gamecost, daysrequested, total, reservationstart, dateend 5,pinball, 3.99,7, 27.99, 01/01/2015, 08/01/2015 

though should said form requires date entry yyyy-mm-dd. have java script conversion.

i've seen one! try this:

while (!feof($file_handle)) {         $loansinfo = fgetcsv($file_handle);         if($loansinfo[0]==$id){                 $fromdate = "$loansinfo[5]";                 $todate ="$loansinfo[6]";                 if (strtotime($dateborrowedfrom) <= strtotime($wanteddate)) {                     if(strtotime($todate) >= strtotime($wanteddate)){                         $cantbook = true;                         }                 }                 else {                     if (strtotime($dateborrowedfrom)  <= strtotime($dateto)) {                         $cantbook= true;                         }                     }                 }             }         fclose($file_handle);          if($cantbook = true){             echo('<script type="text/javascript">alert("game booked");</script>');             }         else{     //saving booking
