How can PHP beginners ensure the proper syntax for variable substitution in strings?

When using variable substitution in strings in PHP, beginners should ensure they use double quotes ("") instead of single quotes (''). This allows for the interpolation of variables within the string. Additionally, variables should be enclosed in curly braces {} to clearly define the variable name within the string. 

// Ensure proper syntax for variable substitution in strings
$name = "John";
$age = 25;

// Correct syntax using double quotes and curly braces
echo "My name is {$name} and I am {$age} years old.";
