如何在codeigniter中的javascript警报中使用php代码

Question

I am using this code in my controller and it's not working, showing parse error. Can you guys please help me out.

 echo "<script>
        alert("<?php echo $v[$keys[$i+4]],"is going out of stock"; ?>");
</script>" ;

Thank you!

You're not concatenating the static text correctly. Try this:

echo "<script>
    alert('" . $v[$keys[$i+4]] . " is going out of stock.');
</script>" ;
