passing converted javascript array from php to javascript function [closed]

Question

I want to pass javascript array(converted from php to js) present in php code to javascript function.

<?php

//php to javascript array conversion
$php_array = array('he','hi','hello');
$js_array = json_encode($php_array);
echo 'var groups = ". $js_array . ";\n';

?>

function codeAddress(groups)
{ alert("into code address function");

        for (var i=0;i<groups.length;i++)
    {
        alert(groups[i]);
    }
}

Answer 1

echo 'var groups = '. $js_array . ";\n";

Variable was not expanded inside single quotes. Don't put output of json_encode into quotes.

Answer 2

try something like this

    //php to javascript array conversion
    $php_array = array('he','hi','hello');
    $js_array = json_encode($php_array);
    echo 'var groups = '. $js_array;
