PHP Need help converting to a string

<?php 

         function create_initials() {
              get_currentuserinfo(); 
                    $string =  "First Last" .     // need this to be dynamic: $current_user->user_firstname . $current_user->user_lastname) ; 

$expr = '/(?<=\s|^)[a-z]/i';
preg_match_all($expr, $string, $matches);

$result = implode('', $matches[0]);

$result = strtoupper($result);

echo $result; }?>

Thank You!

If I understand rightly you are looking for a function to return the initials of the name you input. You've over complicated it a little!

function create_initials($firstname, $lastname) {
    return strtoupper(substr($firstname, 0, 1) . substr($lastname, 0, 1));
}

And then use it like this: create_initials($current_user->user_firstname, $current_user->user_lastname);

When I run: 

      <?php echo create_initials($current_user->user_firstname, $current_user->user_lastname); ?>

The function echoes out: "$$"

It is not treating the variables as variables. It is treating them as strings and running the function accordingly - taking the first letter of each variable which is the $. What am I doing wrong still?

So what is $current_user? Where has it come from? Is it an object or array?

It is an object I am pulling from a wordpress plugin into another part of my project. Here is the full code for my content-user.php: 

 <?php
global $wpdb, $pmpro_msg, $pmpro_msgt, $pmpro_levels, $current_user, $levels, $pmpro_currency_symbol;

//if a member is logged in, show them some info here (1. past invoices. 2. billing information with button to update.)
if($current_user->membership_level->ID)
{
?>  


<?php

function create_initials($firstname, $lastname) {
get_currentuserinfo();
return strtoupper(substr('$firstname', 0, 1) . substr('$lastname', 0, 1));
}
?>

    <div id="pmpro_account-profile" class="pmpro_box row">  

        <div class="circle"><?php echo create_initials($current_user->user_firstname, $current_user->user_lastname); ?></div>

        <h3 class="user-icon col-xs-12"><?php echo $current_user->user_login?></h3>
        <p class="col-xs-12"> Hello <?php echo $current_user->user_lastname?> <?php echo $current_user->user_lastname?>, <br> Welcome back....</p>
        <h5 class="col-xs-12"><?php echo $current_user->user_email?></h5>

        <div class="col-xs-12 edit-profile">
            <a href="<?php echo admin_url('profile.php')?>"><?php _e("Edit Profile", "pmpro");?></a>
        </div>
    </div> <!-- end pmpro_account-profile -->

    <?php } ?>

Take out the single quotes in the function and you shouldn't need get_currentuserinfo() in there.

return strtoupper(substr($firstname, 0, 1) . substr($lastname, 0, 1));
