Are there any best practices for handling strings and variables in PHP to avoid syntax errors?

When handling strings and variables in PHP, it's important to properly concatenate them to avoid syntax errors. One common mistake is forgetting to use the concatenation operator (.) when combining strings and variables. To avoid this issue, always ensure that variables are properly enclosed within double quotes when concatenating them with strings. 

// Incorrect way without proper concatenation
$name = "John";
echo "Hello, $name"; // This will result in a syntax error

// Correct way with proper concatenation
$name = "John";
echo "Hello, " . $name; // This will output: Hello, John
