💡 Hint

Omitting the catch block causes syntax errors.

Using an incorrect catch syntax.

The catch (Exception $e) block catches exceptions and allows the finally block to execute afterward.

2fill in blank

medium

Complete the code to throw an exception inside the try block.

PHP

<?php
try {
    throw new [1]("Error occurred.");
} catch (Exception $e) {
    echo $e->getMessage();
} finally {
    echo "\nFinally block runs.";
}
?>

Forgetting the 'new' keyword.

Throwing a new Exception inside the try block triggers the catch block.

Fix the error in the catch block syntax.

PHP

<?php
try {
    echo "Inside try.\n";
} catch [1] {
    echo "Caught exception.\n";
} finally {
    echo "Finally block executed.\n";
}
?>

💡 Hint

Common Mistakes

Omitting the variable name in catch parentheses.

Using incorrect parentheses syntax.

The catch block must specify the exception type and a variable to hold it, like (Exception $e).

4fill in blank

hard

Fill both blanks to create a finally block that always runs after try and catch.

PHP

<?php
try {
    echo "Trying...\n";
} catch (Exception $e) {
    echo "Exception caught.\n";
} [1] {
    echo "[2] block executed.\n";
}
?>

Fill all three blanks to handle an exception and ensure the finally block runs.

PHP

<?php
try {
    throw new [1]("Error!");
} catch ([2] $e) {
