1. Introduction to PHP Output

Before any application can interact with users, it must present some form of output. PHP provides two primary ways to do this:

• echo
• print

These are language constructs, not functions, which means they can be used without parentheses and are optimized for performance.

2. What is echo in PHP?

echo is used to output one or more strings to the browser.

Syntax:

echo "Hello, World!";

Example:

$name = "John";
echo "Hello, $name!";

Features:

• Faster than print
• Can take multiple parameters
• No return value

echo "One", " Two", " Three";

3. What is print in PHP?

print is also used to output strings, but unlike echo, it always returns 1.

Syntax:

print "Hello, World!";

Example:

$age = 25;
print "Age: $age";

Features:

• Returns a value (1)
• Takes only one parameter

4. echo vs print: Key Differences

5. Using echo with HTML

echo "<h1>Welcome to PHP</h1>";
echo "<p>This is a paragraph.</p>";

This is useful when mixing PHP with HTML templates.

6. Using print with HTML

print "<div><strong>Important Notice</strong></div>";

Just like echo, you can use print to output HTML content.

7. Concatenation in echo and print

PHP uses the dot (.) operator to concatenate strings.

$name = "Alice";
echo "Hello, " . $name . "!";

$greeting = "Good Morning";
print $greeting . ", Alice!";

8. Outputting Variables

$price = 150;
echo "The price is: $price";

9. Outputting Arrays and Objects

To print arrays or objects, use print_r() or var_dump().

$arr = array("PHP", "MySQL", "HTML");
echo "<pre>";
print_r($arr);
echo "</pre>";

For objects:

echo "<pre>";
var_dump($object);
echo "</pre>";

10. Performance Considerations

• echo is marginally faster than print
• In high-performance applications, echo is generally preferred
• Use echo for multi-line HTML templates for better readability

11. Real-World Use Cases

Example: Welcome Message

$name = $_GET['name'] ?? 'Guest';
echo "<h2>Welcome, $name!</h2>";

Example: Print Receipt

print "<h3>Your order has been received.</h3>";

12. Best Practices

• Prefer echo for simple output
• Use double quotes when using variables inside strings
• Escape HTML special characters to prevent XSS

echo htmlspecialchars($user_input);

• Use print when you need to return a value (e.g., inside ternary conditions)

$status = (print "Success") ? true : false;

13. Common Mistakes to Avoid

• Forgetting to escape quotes:

echo "She said, \"Hello!\"";

• Using print with multiple parameters:

print "Hello", "World"; // Invalid

• Ignoring return value of print in expressions
