• Writing large output

• Slightly better performance matters

Use print when:

• You need a return value

• Using it inside expressions

However, most developers prefer echo.

Common Beginner Mistakes

 Forgetting Semicolon

Must end with:

 Using Single Quotes Incorrectly

Variables don’t work inside single quotes.

 Mixing Concatenation Improperly

Wrong:

Correct:

Performance Difference

echo is slightly faster than print because:

• It does not return a value

• It is simpler internally

But in small projects, the difference is negligible.
