Insert variable and PDF tag into PHP code

Question

This should be incredibly simple but i can't seem to figure it out.

I have the following code

<?php
$bookingid='12345';
    include_once('phpToPDF.php') ;
    //Code to generate PDF file from specified URL
    phptopdf_url('https://google.com/','pdf/', $bookingid.pdf);
    echo "<a href='pdf/$bookingid.pdf'>Download PDF</a>";
?>

It echo's correctly however when it comes to generate the pdf...

phptopdf_url('https://google.com/','pdf/', $bookingid.pdf);

...it misses out the fullstop so it generates 12345pdf whereas it should be 12345.pdf.

Again, i apologise for the probable simplicity of this but i can't seem to figure it out.

$bookingid . '.pdf'

$bookingid.pdf

It tells php to concatenate variable $bookingid with constant pdf. Since constant pdf is undefined, it is casted to string and concatenated. Proper code will look like:

$bookingid . '.pdf'

or

"$bookingid.pdf"

This should be

$bookingid.".pdf"

PHP is seeing a string concatenation, concatenating pdf' to $booking. pdf is an undefined string, so PHP helpfully assumes that you mean the text itself, but it misses the full stop you also need.
