This program have syntax error on line

Code:

echo 'Total number of students = ' . ($numboys+numgirls) ;

$ missing for numgirls.

Proper usage.

Code:

<?php

$numBoys = 20;
$numGirls = 25;

echo 'Total number of students = ' . ($numBoys + $numGirls) ;

Only strings values need to be enclosed within quotes (' or ").
