Help with an array please

[adam1984]

First off, thanks for all the help on my last post about a week ago. I'm still trucking along in my PHP book and have another exercise i'm almost done with, but have a question concerning the last sentence in the exericse. I'll first show the exercise in question, then I will show the code I have developed for it. Please take a look at it and let me know what you think!

 

EXERCISE:

Create a function that works with two arguments. The first argument should be a username, and the second should be an email address. Use case conversion functions to capitalize the first letter of the username. Convert the email address to lowercase characters and check that it contains the @ sign. If you can't find the @ character, return false; otherwise, return an array containing the converted arguments. Test the function.

 

My Code:

 

<?php

 

function test($username, $email) {

 

if (strstr($email, "@")){

 

print ucwords($username);

print "<br />";

print strtolower($email);

 

} else {

 

print "No dice, FALSE";

 

}

 

}

 

test("adam1984", "[email protected]");

 

?>

 

My code runs fine, however I'm not sure if this is what they're asking for since it wants me to return an array containing the converted arguments??? What do you all think? I thank you in advance,

 

Sincerely,

AdMAN

Rather then print the username/email when you have converted them assign the to a variable, eg $username, $email then use the following to return an array

return array($username, $email)

 

Change

print ucwords($username);
print "<br />";
print strtolower($email);

} else {

print "No dice, FALSE";

to

$username = ucwords($username);
$email = strtolower($email);

return array($username, $password);

} else {

return;

hm, trying what you have there.. maybe i'm missing something.. what would the entire code be inside my php tags? thanks..

You only need to change the code in the function, which is what I highlighted in my post above

 

However when calling the function you'd do something like this

// call the function
// as the function now returns something we need to catch it
$info = test("adam1984", "[email protected]");

// check that the function returned an array
if(is_array($info))
{
    echo 'Username is: '. $info[0]. '<br />';
    echo 'Email is: '. $info[1]. '<br />';
}
else
{
    echo 'FAILED';
}
