How to Concatenate Strings in PHP Without Using the \' \' Operator?

PHP String Concatenation

In PHP, string concatenation involves combining multiple strings into a single string. While the ' ' operator can be used for numeric addition, it cannot be used for string concatenation.

Alternative to Using ' ' for Concatenation

The alternative to using ' ' is the '.' operator. Consider the following example:

$result = '';
$personCount = 1;

while ($personCount < 10) {
    $result .= $personCount . ' person ';
    $personCount++;
}

echo $result;

In this example, we use the '.' operator to concatenate the string 'person ' to each iteration of the loop. The result will be "1 person 2 person 3 person" and so on.

Additional Note

In your original example, you did not increment the $personCount variable within the loop, resulting in an infinite loop. The correct version of the loop is provided in the alternative code block above.
