How can PHP developers ensure proper concatenation of strings and variables to prevent syntax errors?

To ensure proper concatenation of strings and variables in PHP to prevent syntax errors, developers should use the concatenation operator (.) to combine strings and variables within double quotes. This helps avoid unexpected syntax errors that may occur when trying to concatenate variables directly within double quotes. 

$name = "John";
$age = 30;

// Correct way to concatenate strings and variables
echo "My name is " . $name . " and I am " . $age . " years old.";
