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
Feature | echo | print |
---|---|---|
Speed | Faster | Slightly slower |
Return Value | No | Yes (returns 1) |
Parameters | Multiple allowed | Only one |
Usage | Display output | Display + return |
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 thanprint
- 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
