How can conditional statements be used to control the replacement of text in PHP?

Conditional statements in PHP can be used to control the replacement of text by checking for specific conditions before performing the replacement. For example, you can use an if statement to check if a certain word exists in a string before replacing it with another word. This allows you to customize the replacement based on different conditions, providing more flexibility in text manipulation. 

$text = "Hello World";
$newText = '';

if (strpos($text, 'World') !== false) {
    $newText = str_replace('World', 'Universe', $text);
} else {
    $newText = $text;
}

echo $newText; // Output: Hello Universe
