Error showing past time of multiple PHP posts

Question

<?php
function timeAgo($time_ago){
$cur_time   = time();
$time_elapsed   = $cur_time - $time_ago;
$seconds    = $time_elapsed ;
$minutes    = round($time_elapsed / 60 );
$hours      = round($time_elapsed / 3600);
$days       = round($time_elapsed / 86400 );
$weeks      = round($time_elapsed / 604800);
$months     = round($time_elapsed / 2600640 );
$years      = round($time_elapsed / 31207680 );
// Seconds
if($seconds <= 60){
    echo "$seconds segundos atrás";
}
//Minutes
else if($minutes <=60){
    if($minutes==1){
        echo "um minuto atrás";
    }
    else{
        echo "$minutes minutos atrás";
    }
}
//Hours
else if($hours <=24){
    if($hours==1){
        echo "uma hora atrás";
    }else{
        echo "$hours horas atrás";
    }
}
//Days
else if($days <= 7){
    if($days==1){
        echo "ontem";
    }else{
        echo "$days dias atrás";
    }
}
//Weeks
else if($weeks <= 4.3){
    if($weeks==1){
        echo "à uma semana";
    }else{
        echo "$weeks semanas atrás";
    }
}
//Months
else if($months <=12){
    if($months==1){
        echo "um mês atrás";
    }else{
        echo "$months meses atrás";
    }
}
//Years
else{
    if($years==1){
        echo "um ano atrás";
    }else{
        echo "$years anos atrás";
    }
}
}

?>
<?php
  $curenttime=$date_uploaded;
  $time_ago =strtotime($curenttime);
  echo timeAgo($time_ago);
?>

Whereas $date_upload is equal to (dd-mm-yy hh:mm:ss) in the database.

This is the code, when I pull only one post it works, but when I pull several posts gives this error:

error: Cannot redeclare timeAgo() (Previously declared in C: xampp htdocs site poster.php:520) in)

Answer 1

The error says that there is two or more times a function with the same name in your file or in the call of a include.

To solve the problem, I suggest you have at least two files, one with normal code processing and the other with only a small library functions, thus avoiding the collision of function names. Another alternative from php5.3 is to use name espaces.

There are some tools that identify code duplication and copy & Paste as the php mess dectector, also helps in identifying such collisions.

Example - simulated error.

Example - solution with namespaces.
