how to assign php array values to javascript array

Please provide help on how to assign php array values to javascript array

----------- Using below php code I am storing data in php array -----------

$str_query="SELECT title,description FROM tablename ORDER BY title";

$schd_arr = array();
$schd_arr[$int_count] = $rs_sch->Fields("title").": ".$rs_sch->Fields("description");

----- Using below javascript code I am trying to store php array data into javascript array -----

Please let me know what and how to write variable at below 2 mentioned locations so my code can work.

<script type="text/javascript" language="javascript">
var pausecontent=new Array()
for (sch_cnt=0; sch_cnt<*Here I want to assign value of $int_count php variable*; sch_cnt++)
pausecontent[sch_cnt]=<?php *Here I want to assign php array and counter values (something like this - $schd_arr[sch_cnt];)* ?>;

Thank you in advance, KRA



You can't loop like that, you need to loop the PHP array and push into javascript array:

<script type="text/javascript" language="javascript">
    var pausecontent = new Array();
    <?php foreach($schd_arr as $key => $val){ ?>
        pausecontent.push('<?php echo $val; ?>');
    <?php } ?>

You can directly use the json_encode function. It is easy to use and produces valid javascript so is very stable:

<script type="text/javascript">
    var pausecontent = <?php echo json_encode($php_array); ?>;

I think you'd best get the array to your javascript first. That would be something like this:

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

After that it is a normal js array, so you can use properties like .length which will presumably make the loop much easier.


I had the same problem doing this but finally found the best solution

    var arr=[];
        $query = "SELECT *FROM c group by name";
        $res = mysqli_query($conn,$query) or die(mysqli_error($conn));

        while($data = mysqli_fetch_array($res))

             echo $data["name"];

Above both answers in good.

  1. Iterate through the array you got as a result of your DB query and add each value to a new PHP variable,
  2. Add a counter and increment it during each iteration to make sure that you’re not adding a comma after the last element,
  3. If the count of the elements in the array is more than 1, create the array as usual, otherwise create a new array with 1 element and assign your PHP array value to the index 0.
