How to pass PHP variables to a Javascript function

Question

I don't understand why the addRow method isn't reading the parameters and I know for a fact they are initialized.

In php
echo "<script> addRow(".$song.",".$artist."); </script>";

JavaScript method

function addRow(s,a){
        document.write("test");
    }

echo "<script> addRow('".$song."','".$artist."'); </script>";//quote values — user2959229

Or for better readability, no need to concatenate: echo "<script> addRow('$song', '$artist'); </script>"; — Honza Haering

Don't forget your quotes!

echo "<script> addRow( '".$song."', '".$artist."' ); </script>";

Or nicer even:

echo "<script> addRow( '{$song}', '{$artist}' ); </script>";

PHP

<script> addRow('".$song."','".$artist."'); </script>

JavaScript

function addRow(s,a){
    console.log(s);
    console.log(a);
    document.write("test");
}

im sorry what is the console.log for?

The JavaScript part is not of particular value.

console.log is for the display of params, when you try to get them in your function, it is nice to verify it works
