I have a smiliar loop:

$names = "
[$name , $surname]
";

echo "$names";

The result:

[Mario,Rossi]
[Aberto,rossi]
[Giovanni,Rossi]

i would this output:

[Mario,Rossi],
[Aberto,rossi],
[Giovanni,Rossi]

Without , in the last result
* I can't know the number of results in the loop

• php
• loops

Using a simple array implosion will do the trick here:

$names[] = "[$name, $surname]";
echo implode(",\n", $names);

$names[] = "
[$name , $surname]
";

$comma_sep = implode(",", $names);

echo "<pre>{$comma_sep}</pre>";

The data should be pre-formatted with <pre> tags if you want to use your line breaks like that.
