Practice

1. What does the {{ }} syntax do in a Laravel Blade template?

easy

A. It displays data safely by escaping HTML characters.

B. It runs PHP code without showing any output.

C. It comments out the code inside it.

D. It includes another Blade template file.

Solution

1. Step 1: Understand Blade syntax purpose

   The {{ }} syntax is used to show data inside Blade templates.

2. Step 2: Recognize automatic HTML escaping

   Laravel automatically escapes HTML inside {{ }} to protect from security issues.

3. Final Answer:

   It displays data safely by escaping HTML characters. -> Option A

4. Quick Check:

   Echoing data with escaping = A [OK]

Hint: Remember {{ }} always escapes output for safety [OK]

Common Mistakes:

• Thinking {{ }} runs PHP code directly
• Assuming {{ }} includes files
• Confusing {{ }} with comments

2. Which of the following is the correct way to display a variable named $name in a Blade template?

easy

A. @php echo $name; @endphp

B. {{ $name }}

C. {!! $name !!}

D. @include('name')

Solution

1. Step 1: Identify Blade echo syntax

   To display a variable safely, Blade uses {{ $variable }}.

2. Step 2: Compare options

   {{ $name }} uses {{ $name }}, which is the correct Blade syntax for echoing variables.

3. Final Answer:

   {{ $name }} -> Option B

4. Quick Check:

   Variable display uses {{ }} = D [OK]

Hint: Use {{ $variable }} to show variables safely [OK]

Common Mistakes:

• Using raw PHP tags instead of Blade syntax
• Using {!! !!} which does not escape HTML
• Trying to include variable as a template

3. Given the Blade code: <p>Hello, {{ $user->name }}!</p> and $user->name = '<strong>Alice</strong>', what will be the rendered HTML output?

medium

A. Hello, <strong>Alice</strong>!

B. Hello, Alice!

C. Hello, {{ $user->name }}!

D. Hello, <em>Alice</em>!

Solution

1. Step 1: Understand Blade escaping

   The {{ }} syntax escapes HTML tags, so <strong> will show as text, not bold.

2. Step 2: Predict output

   The output will show the tags as escaped text: <strong>Alice</strong>.

3. Final Answer:

   <p>Hello, <strong>Alice</strong>!</p> -> Option A

4. Quick Check:

2. Step 2: Verify Blade property access

   Blade supports accessing object properties inside {{ }} syntax.

3. Final Answer:

   There is no error; the code is correct. -> Option D

4. Quick Check:

   Proper property access in Blade = A [OK]

Hint: HTML encodes -> as ->; Blade handles it correctly [OK]
