How can PHP syntax errors be identified and resolved when working with variables?

PHP syntax errors related to variables can be identified and resolved by carefully checking for typos, missing semicolons, or incorrect variable names. It is important to ensure that variables are properly declared and used within the code. Using an integrated development environment (IDE) with syntax highlighting can also help in identifying syntax errors related to variables. Example:

$name = "John";
$age = 25;

echo "My name is " . $name . " and I am " . $age . " years old.";
