Question

I am trying to work out how to write php functions, so that I don’t have to keep writing a block of code over and over again, I am having a play around and tried writing this, but it doesnt work for some reason, can anyone tell me where I am going wrong ?.

<?php
$greeting 'Hello';

function frank ()
{
$name = 'frank';
$2nd = 'robson';
echo $greeting;
echo $name;
echo $2nd;
}


echo frank()
?>

Answer 1

Instead of echoing inside your function you should consider returning a string with it. Also prefer passing a parameter instead of using global scope :

$greeting = 'Hello';

function frank ($funcGreetings)
{
    $name   = 'frank';
    $second = 'robson';
    //Concat variable together an return them
    return $funcGreetings.' '.$name.' '.$second;
}


echo frank($greeting);

Finally a variable name start with a letter or an underscore so $2nd is not a valid name.
