getName()

[jacob1986]

I have been given the problem 'write a function called getName() which has three parameters: Christian name, Surname and middle initial. Moreover, return a string in the format of "Smith, John K".'

 

Starting code:

 

echo getName('john',  'smith', 'k');

 

The only code, which I have thus been able to write - please see below... and it's pitiful!

 

<?php
$xml=<<<XML
<?xml version="1.0" standalone="yes"?>
<john>
</john>
XML;
$sxe=new SimpleXMLElement($xml);
echo $sxe->getName() . "<br>";
?>

Perhaps the following will help:

I have this code (while it works - it doesn't seem to help me with the inclusion of the string... echo getName('john',  'smith', 'k');

 

<?php
function getName($getName = "K")
{
    return "John Smith $getName.\n";
}
echo getName();

?>

 

Prints:

 

John Smith K.

Your function is only set up to accept one argument. To pass three ('john', 'smith', and 'k'), you'll need to modify the function definition.

<?php

function getName($Christianname, $Surname, $middlename = "") {

    return ucwords($Surname . ", " . $Christianname . " " . $middlename) ;
}
echo  getName('john', 'smith', 'k.');

?>

That seems like it would work. Did you have any additional questions?

No more questions on this but thank-you

To be on the safe side, in case the input is "JOHN SMITH".

function getName ($first,  $last, $middle='') 
{
    return ucwords(strtolower("$last, $first $middle"));
}

echo getName('JOHN', 'SMITH', 'K');    //--> Smith, John K

Also note when using double-quotes you don't need the string concatenation.
