How to Correctly Concatenate Strings in PHP?

PHP String Concatenation: Limitations and Alternatives

In PHP, string concatenation involves joining multiple strings into a single string. However, unlike some other programming languages, it's important to note that operators such as ' ' cannot be used for this purpose.

As the provided code demonstrates, attempting to concatenate strings using ' ' while looping through a counter (e.g., while ($personCount < 10)) will result in incorrect output. In this specific scenario, the desired outcome is a sequence of strings like "1 person," "2 person," and so on.

The correct approach for string concatenation in PHP is to use the '.' operator. By replacing the ' ' with '.' in the example code, you can achieve the desired output, as seen below:

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

echo $result;

This code efficiently concatenates the counter and the string 'people' to produce the expected result: "1 person 2 person 3 person..."
