Question 278426 in PHP Question posted in
Official manual can be found here.

assign foreach to variable using php

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?

    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;

    As I adhere from the comments and the questions you want to concatenate each message separately

    $final_message = []; 
foreach ($codes as $code => $total)  {
    printf("%s <font color='blue'><b>Total clicks = %d<br></b></font>", $code, $total); 
   // message5 or 4 it doesn't matter it will get each message on each iterate
    $message5 = sprintf("%s <font color='blue'><b>Total clicks = %d<br></b></font>", $code, $total); 
    $final_message[] = $message5;
}
var_dump($final_message); // $final_message[0], $final_message[1] etc..
