Use php's echo to return html/css/js stuff: http://php.net/manual/de/function.echo.php

<?php
$delete = "
    <a onclick='confirm_(\"deleterecord.php?chkid=$sl&table=$getid&path=$validURL'\")'; class='link'>
        <img src='images/dustbin.png' width='43px' height='30px'>
    </a>";
echo($delete);
?>
<script>
function confirm_(url){
        console.log(url);
        if (confirm("Are you sure you want to delete")){
            window.location = url;
        }
}
</script>

Like Rayon Dabre sayed, you have to escape string.

Maurize's casual/smart/lazy solution:

You should echo a link with a path like delete.php?action=delete&id=2

and on php side

if (isset($_GET["action"]) && $_GET["action"] == "delete"){ echo $_GET["id"]; }

Will looks like:

<?php
if (isset($_GET["action"]) && $_GET["action"] == "delete"){
    echo $_GET["id"];
}
?>
<a href="index.php?action=delete&id=1">Lazy Casual?</a>

or

<?php
echo("
<a href='deleterecord.php?chkid=$sl&table=$getid&path=$validURL'>
    <img src='images/dustbin.png' width='43px' height='30px'>
</a>
");
?>

Tested and works like mexican.

The masterpiece of deletion would be using AJAX + JS - Maurize

yes i have already echo but the link is not pass into the function due to ' ' (commass) — SANJOG, Oct 06 '15 at 08:23

1. $link = "deleterecord.php?chkid=$sl&table=$getid&path=$validURL";

and use

return confirmDelete(\"<?=$link?>\")

2. Escape single quotes by using black slash before single quote:

  <img src=\'images/dustbin.png\' width=\'43px\' height=\'30px\'>
