Home » Javascript & Libraries, PHP/MySQL » Convert PHP array to Javascript array

A very basic tutorial. For the beginners who want to pass array values from PHP to Javascript for them to be accessible in the client side JS as an array. It’s really easy to pass PHP array to Javascript.

The below code passes a string array in PHP to Javascript.

$arr = array("a","b","c");
var jsArray = ["<?php echo join("\", \"", $arr); ?>"];

    1. If I understand your problem correctly, I believe you want to display a tabular data in your web page and then allow your users to download the same data as an excel file. You don’t need to bring in Javascript if this is what you need to achieve. Query your database table and display them on your page in a table. When user clicks on the download link, you will call another php page which will again query the same database as above and generate the content for the excel file and give it back to the user.

    2. If you still want to pass the PHP array to Javascript and then pass it to another page through Javascript, you should not pass the data through URL. Convert your PHP array to a JSON string and store it in a variable in Javascript. Then, when you want the Javascript data to be sent to another page, you can create a POST request from Javascript to the second PHP page to send the JSON data. PHP can then decode this string in to an Array.

    Above are two concepts. If I am clear and you are able to choose the way you want to go ahead, I can elaborate the solution.

    Thanks mate. Really appreciate your help. Its been very helpful.

  10. php code =========
    //create php test array
    $testarray = array(‘zero’, ‘one’, ‘two’, ‘three’, ‘four’);
    //convert array to string using “:#:” as separator
    //using complex separator insures that it is not part of array element
    $testvar = implode(“:#:”,$testarray);
    php code ends =========

    function showArray()
    //Convert Php string to JavaScript string
    var testvar = “”;
    //Create JavaScript array
    var testarray = new Array();
    var x;
    //Fill JavaScript array from the converted string
    testarray = testvar.split(“:#:”);
    //Display output of all the array elements;
    for( x=0; x<5; x++){
    document.write( testarray[x] + "” );

    Hi everyone! sorry! i’m very beginner in programing but it’s like a hobby and i like learning. For now i’m trying to make a google maps like map (OpenStreetMap) and trying to learn how to load the array from php not using(for now) JSON and AJAX(cause i’m far from it). So I have a php array with coordinates and some other staff. Also i have checkboxes on page which are restaurants, museums e.t.c. With js by the ‘for’ cicle i’m working with checkboxes but i can’t connect the value from checkbox with the php array’s name and load it. tell me please what’s wrong?

    array (“inform.kg”,”74.61920″,”42.83772″,”ugfjfh”,”2″),
    2 => array (“inform.kg2″,”74.61930″,”42.83762″,”ugfh”,”2″)

    function checkBox(){
    var checkBoxes = document.getElementsByTagName(‘input’);
    for(var i=0; i<checkBoxes.length; i++){
    if (checkBoxes[i].id == 'check'){
    if(checkBoxes[i].checked == true){
    var obj_name = checkBoxes[i].value;
    var objs = [""];;

    <input name="internet" id="check" onclick="checkBox()" value="” type=”checkbox”>inform agency
    <input name="internet" id="check" onclick="checkBox()" value="” type=”checkbox”>inform agency2

  14. den says:

    ”var objs = [""];;” so instead of “$internet” i wan’t to pass another variable (JS Array) to work with it! help me please! :)

  15. den says:
