PHP Syntax

Every PHP file starts using:

<?php

---

Example

<?php

echo "Hello Zyro!";

---

Statements

Every statement ends with:

;

Example:

$name = "Aayan";
echo $name;

---

Case Sensitivity

Variables are case-sensitive.

$name = "Aayan";
$Name = "Steve";

These are different.

---

Whitespace

PHP ignores extra spaces.

$name      =      "Aayan";

---

Multiple Statements

echo "Hello";
echo "World";

---

Embedding HTML

<h1>

<?php
echo "Hello";
?>

</h1>

---

Best Practice

Always start files with:

<?php

declare(strict_types=1);

---

Example

<?php

declare(strict_types=1);

echo "Welcome";

---

Exercises

Create:

echo "Hello World";
