In listing 3.4, the zip code value is given as a decimal
cities.zip_lookup( 10016 );

But running this code in strict mode with a zip code that begins with a zero
cities.zip_lookup( 07946 );

results in an error.

Suggestion: change the code to pass the zip code value as a string
cities.zip_lookup( '07946' );
