Why did the user not receive a syntax error despite the mistake in the code?

The user did not receive a syntax error despite the mistake in the code because PHP is forgiving when it comes to certain syntactic errors. In this case, the mistake may have been a minor one that PHP was able to interpret correctly without throwing an error. To prevent such issues in the future, it is essential to pay close attention to syntax rules and best practices while coding.

// Incorrect code
echo "Hello, World"
echo "This is a syntax error";

// Corrected code
echo "Hello, World";
echo "This is a syntax error";
