How Does PHP Perform String Concatenation?

PHP String Concatenation

In PHP, string concatenation can be achieved using the dot operator (.). In your example, you can concatenate the strings as follows:

while ($personCount < 10) {
    $result .= $personCount . " person "; // Use . for concatenation
    $personCount++; // Increment $personCount
}

echo $result;

This will result in the expected output:

1 person 2 person 3 person ...

The sign cannot be used for concatenation in PHP. If you attempt to use it, the strings will be added as numbers. Therefore, it's important to use the correct operator (.) for string concatenation.
