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

  • Use $message5 .= sprintf(... Commented Nov 3, 2023 at 18:05

  • yes how to stop the overwriting? Commented Nov 3, 2023 at 18:40
  • What was already sent .= assigns to existing variable. Commented Nov 3, 2023 at 18:48

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;

works in the echo on screen but does not give the output in the mailout
what is the mailout? how are you trying to use it? assign each line to a dynamic variable? or the full data in a single variable?
what is the mailout? maybe is better to describe the whole scenario you have in mind - WDYT?
trying to use $message5 to assign each line of output in the email, so I have $message = $message1. " ".$message2. " ". $message3. " ". $message5, my email line is mail($emailaddress[$z], $emailsubject, $message, $headers);
@mark.four It should work. Are you sure you changed = to .=?

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..

Mostafa Ezzat, thanks, works on the screen, but Still only gives the last line on the mail line, mail($emailaddress[$z], $emailsubject, $message, $headers);
try $final_message = imploade("", $final_message); mail($emailaddress[$z], $emailsubject, $final_message , $headers);

If I assume your $codes variable matches below data, then it would work without any issue... if still doesn't work please show us whole code to check...

$codes = array(
    '01 output 1' => 1,
    '02 output 2' => 1,
    '03 output 3' => 1,
    '03 output 4' => 1,
    '03 output 5' => 1,
);

$message5 = '';

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

mail( $emailaddress[$z], $emailsubject, $message5, $headers );
