Can you append strings to variables in PHP? [duplicate]

Answer 1

PHP syntax is little different in case of concatenation from JavaScript. Instead of (+) plus a (.) period is used for string concatenation.

';
for ($i=1;$i<=100;$i++)
{
    $selectBox += '' . $i . ''; // <-- (Wrong) Replace + with .
    $selectBox .= '' . $i . ''; // <-- (Correct) Here + is replaced .
}
$selectBox += ''; // <-- (Wrong) Replace + with .
$selectBox .= ''; // <-- (Correct) Here + is replaced .
echo $selectBox;

?>
