🐘 About This PHP Online Executor

The CodeUtility PHP Executor lets you write and run PHP code directly in your browser - no setup, server, or installation required. It runs real PHP environments in isolated sandboxes, supporting versions from 5.6 up to the latest 8.2.

Whether you're testing snippets, learning PHP basics, or exploring new syntax and library features, this tool provides a lightweight and interactive environment to execute your PHP code instantly.

You can quickly check logic, debug functions, or practice for interviews - all within your browser, with real-time output displayed in the built-in console.

It’s ideal for students, developers, and web engineers who need a quick way to experiment with PHP or validate snippets before deploying them to a real web server.

More than a code runner

Use a multi-file editor, an isolated execution terminal, runtime-specific libraries, persistent workspaces, sharing, and real-time collaboration from the same executor.

How to use this executor?

Choose a runtime, open or create a file, write your code, and select Run. Output appears in the terminal, while signed-in users can keep files in a workspace, install libraries, and collaborate through shares.

  1. Select a version and edit the current file or open another workspace file.
  2. Run the code, provide input in the terminal when requested, and review saved run history.
  3. Use libraries, workspace tools, sharing, and chat when your task needs more than one snippet.

💡 PHP Basics & Examples You Can Try Above

1. Declaring Variables and Constants

PHP variables start with $. Use define() or const for constants.

$x = 10;
$pi = 3.14;
$name = "Alice";
$isActive = true;

define("MAX_USERS", 100);
const APP_NAME = "CodeUtility";

2. Conditionals (if / switch)

Use if, elseif, and else for branching, or switch for multiple cases.

$x = 2;
if ($x == 1) {
    echo "One\n";
} elseif ($x == 2) {
    echo "Two\n";
} else {
    echo "Other\n";
}

switch ($x) {
    case 1:
        echo "One\n";
        break;
    case 2:
        echo "Two\n";
        break;
    default:
        echo "Other\n";
}

3. Loops

PHP supports for, while, and foreach loops.

for ($i = 0; $i < 3; $i++) {
    echo $i . "\n";
}

$n = 3;
while ($n > 0) {
    echo $n . "\n";
    $n--;
}

4. Arrays

Arrays hold multiple values. PHP supports indexed and associative arrays.

$nums = array(10, 20, 30);
echo $nums[1];

5. Array Manipulation

Use functions like array_push(), array_pop(), count(), and slicing with array_slice().

$fruits = ["apple", "banana"];
array_push($fruits, "cherry");
array_pop($fruits);
print_r($fruits);

$sliced = array_slice($fruits, 0, 1);
print_r($sliced);

6. Console Input/Output

Use readline() for CLI input and echo/print for output.

$name = readline("Enter your name: ");
echo "Hello, $name\n";

7. Functions

Functions encapsulate reusable logic. Parameters can have default values.

function greet($name = "Guest") {
    return "Hello, $name";
}

echo greet("Alice");

8. Associative Arrays

PHP arrays can act like dictionaries with string keys.

$person = ["name" => "Bob", "age" => 25];
echo $person["name"];

9. Exception Handling

Use try, catch, and throw to handle errors.

try {
    throw new Exception("Something went wrong");
} catch (Exception $e) {
    echo $e->getMessage();
}

10. File I/O

Use functions like fopen(), fwrite(), and fread() for file operations.

$file = fopen("test.txt", "w");
fwrite($file, "Hello File");
fclose($file);

$file = fopen("test.txt", "r");
echo fread($file, filesize("test.txt"));
fclose($file);

11. String Manipulation

Use functions like strlen(), str_replace(), and explode().

$text = "Hello World";
echo strlen($text);
echo str_replace("Hello", "Hi", $text);
print_r(explode(" ", $text));

12. Classes & Objects

Use classes to model real-world objects and reuse logic.

class Person {
  public $name;
  function __construct($name) {
    $this->name = $name;
  }
  function greet() {
    return "Hi, I'm " . $this->name;
  }
}

$p = new Person("Alice");
echo $p->greet();

13. References

In PHP, you can pass variables by reference using &.

function addOne(&$num) {
    $num++;
}

$x = 5;
addOne($x);
echo $x; // 6
