PHP array into Javascript Array

问题

Afternoon all. The code below works perfectly, however, I need to pull each row of the php sql array out and into the script var. Any ideas on how to write a while loop that could do this? Thanks for any help

 var enableDays = ["<?php echo mysql_result($result, 0, 'date'); ?>"];

 enableDays.push("<?php echo mysql_result($result, 1, 'date'); ?>");

Additional Code::

$rows = array();

while ($row = mysql_fetch_assoc($result))
{
    $rows[] = $row;
}



    var enableDays = [<?php echo json_encode($rows); ?>];

    console.log(enableDays[1]);

回答1:

You can get the rows using mysqli_fetch_assoc and then encode it to JSON:

<?php
$rows = array();

while ($row = mysqli_fetch_assoc($result)) {
    $rows[] = $row;
}
?>


var enableDays = <?php echo json_encode($rows); ?>;

Pull your data out into a PHP array, then transfer that to JavaScript with

var enableDays = <?php echo json_encode($enableDays); ?>;

As an aside, the obligatory recommendation that you should stop using the PHP mysql extension immediately because it is not very safe and has been deprecated; switch to something better (mysqli and PDO are both good choices).

This can't work. Once the page is loaded, all the PHP has run already. But if you're really just adding the next mysql_result for each push, you could have PHP create the entire enableDays array for you:

<?php
  echo 'var enableDays = ["' . mysql_result(...) . '", "' . mysql_result(...) . '"];'
?>

Hope this would help

  <?php 
    $res = mysql_fetch_assoc($result)
    foreach($res as $key => $val){ ?>
            enableDays.push('<?php echo $val; ?>');
    <?php } 
  ?>
