In the provided code snippet, what are the drawbacks of constructing a string with only a variable instead of directly incorporating the variable value?

Constructing a string with only a variable without directly incorporating the variable value can lead to readability issues and potential errors if the variable value is complex or contains special characters that may affect the string formatting. To solve this issue, it is recommended to directly incorporate the variable value within the string using concatenation or interpolation to ensure clarity and accuracy. 

// Original code snippet
$name = "Alice";
$message = "Hello, $name!";

// Fixed code snippet
$name = "Alice";
$message = "Hello, " . $name . "!";
echo $message;
