Passing Php Array Into External Javascript Function As Array

I'm doing something which I need to pass an array from my php to a function on an external javascript. I'm currently doing some test right now which looks like this:

Solution 1:

Use json_encode

onclick='show_error_message(<?phpecho  json_encode($array_sample) ?>)'

or

onclick="show_error_message(<?phpecho htmlspecialchars(json_encode($array_sample)) ?>)"

Notice the lack of quotes(') around the php code, this way an array literal is passed to show_error_message and not a string.

Solution 2:

Encode PHP array to json data using json_encode() function.

And in Javascript use JSON.parse() to parse the Json string.

Solution 3:

The below code shows how to pass php array to javascript:

<scripttype="text/javascript">functionmufunc(a)
    {
        var temp = newArray();
        temp = a.split('~');
        for(i=0;i<temp.length;i++)
        {
            alert(temp[i]); 
        }
    }
</script><?php$a = array('a','b','c');
    $b = implode("~",$a);
?><ahref="javascript:void(0)"onClick="mufunc('<?phpecho$b; ?>')">Click Here</a>
