What role does proper syntax, such as including opening and closing PHP tags, play in preventing errors like "Parse error: syntax error"?

Proper syntax, such as including opening and closing PHP tags, plays a crucial role in preventing errors like "Parse error: syntax error" because PHP requires specific syntax rules to interpret and execute code correctly. To resolve this issue, ensure that all PHP code is enclosed within <?php and ?> tags, and pay attention to correct usage of semicolons, parentheses, and curly braces.
