assign foreach to variable using php

Question

I have this code

foreach ($codes as $code => $total)  {
    printf("%s <font color='blue'><b>Total clicks = %d<br></b></font>", $code, $total); 
}

Which gives me the output

01 output 1 Total clicks = 1
02 output 2 Total clicks = 1
03 output 3 Total clicks = 1
03 output 4 Total clicks = 1
03 output 5 Total clicks = 1

etc

How can I assign the output to a variable to use in a mailout i.e.

$message5 = each line of output

so that my mail out shows the same ouput

01 output 1 Total clicks = 1
02 output 2 Total clicks = 1
03 output 3 Total clicks = 1
03 output 4 Total clicks = 1
03 output 5 Total clicks = 1

a member suggested using sprintf so I tried this

foreach ($codes as $code => $total)  {
    printf("%s <font color='blue'><b>Total clicks = %d<br></b></font>", $code, $total); 
    $message5 = sprintf("%s <font color='blue'><b>Total clicks = %d<br></b></font>", $code, $total); 
}

But it only gives me the last line of output user3783243 suggests that

$message5 =  overwrites on every iteration 

How can I stop the overwrite?

Please note this issue has now been resolved

Let's try with this

    $message = '';
            
    foreach ($codes as $code => $total)  {
        $message .= sprintf("%s <font color='blue'><b>Total clicks = %d<br></b></font><br>", $code, $total); 
    }

    echo $message;
