Question

Is there a query to run in php that would let you insert all dates in between two dates?

For example, entering 03/20/2012 and 03/20/2013 and populating mysql with all the dates in between the two?

I was making a ticketing system for an airline and they have 13 flights daily from 20+ locations and inserting them manually was getting tedious.

I wanted to insert the dates as well as the values for each day

EG.

 FROM                TO              Date_From              Date_To
     Dar Es Salaam      Zanzibar         03/20/2012             03/21/2012
     Dar Es Salaam      Zanzibar         03/21/2012             03/22/2012

Note

I do not want to GENERATE this list (the questions I’ve researched only answered how to generate a list) I want to POPULATE a MySQL DB

Any help would be greatly appreciated

You could use this function to generate an array of dates

function dateRange( $first, $last, $step = '+1 day', $format = 'd/m/Y' ) {

    $dates = array();
    $current = strtotime( $first );
    $last = strtotime( $last );

    while( $current <= $last ) {

        $dates[] = date( $format, $current );
        $current = strtotime( $step, $current );
    }

    return $dates;
}

$dateRange = dateRange("03/20/2012", "03/20/2013);

and then iterato over the array to insert the data

$stmt = $dbh->prepare("INSERT INTO table (from, to, date_from, date_to) VALUES (:from, :to, :datefrom, :dateto)");
$stmt->bindParam(':from', "Dar Es Salaam");
$stmt->bindParam(':to', "zanzibar");
$stmt->bindParam(':from', $datefrom);
$stmt->bindParam(':to', $dateto);
for ($i = 0; $i < count($dateRange); $i++){
   $datefrom  = strototime($dateRange[$i]);
   $dateto  = strototime($dateRange[$i+1]);
   $stmt->execute();
}
