💡 Hint

Common Mistakes

Using variable names without $ inside PHP blocks.

Using function calls like count() when variable is intended.

Inside raw PHP blocks, variables must have the $ sign to be valid PHP.

4fill in blank

Practice

1. What is the main purpose of using @php in a Laravel Blade template?

easy

A. To define routes in Laravel

B. To include CSS styles directly

C. To create database migrations

D. To write raw PHP code inside the Blade template

Solution

1. Step 1: Understand Blade template usage

   Blade templates allow embedding PHP code for dynamic content.

2. Step 2: Identify the role of @php

   The @php directive lets you write plain PHP code inside Blade templates.

3. Final Answer:

   To write raw PHP code inside the Blade template -> Option D

4. Quick Check:

   @php is for raw PHP code [OK]

Hint: Remember @php means raw PHP inside Blade [OK]

Common Mistakes:

• Confusing @php with CSS or HTML directives
• Thinking @php defines routes or migrations
• Using @php to write JavaScript code

2. Which of the following is the correct syntax to write raw PHP code inside a Blade template using @php?

easy

A. @php { echo 'Hello'; }

B.

C. @php echo 'Hello'; @endphp

D. @php echo 'Hello';

Solution

1. Step 1: Recall Blade raw PHP syntax

   Blade uses @php to start and @endphp to end raw PHP blocks.

2. Step 2: Check each option

   @php echo 'Hello'; @endphp correctly uses @php and @endphp to wrap PHP code.

3. Final Answer:

   @php echo 'Hello'; @endphp -> Option C

4. Quick Check:

   Raw PHP block must start with @php and end with @endphp [OK]

Hint: Use @php ... @endphp to wrap PHP code in Blade [OK]

Common Mistakes:

• Omitting the closing @endphp
• Using curly braces instead of @endphp
• Using raw PHP tags inside Blade without @php

3. What will be the output of the following Blade snippet?

@php
  $count = 3;
  for ($i = 1; $i <= $count; $i++) {
    echo "Item $i ";
  }
@endphp

medium

A. Item 1 Item 2 Item 3

B. Item 123

C. Item $i Item $i Item $i

D. Syntax error

Solution

1. Step 1: Analyze the PHP loop inside @php block

   The loop runs from 1 to 3, echoing "Item " plus the current number and a space each time.

2. Step 2: Determine the output string

   It prints "Item 1 ", then "Item 2 ", then "Item 3 ", concatenated as one string.

3. Final Answer:

   Item 1 Item 2 Item 3 -> Option A

4. Quick Check:

   Loop prints each item with number and space [OK]

Hint: Loops inside @php behave like normal PHP loops [OK]

Common Mistakes:

• Thinking echo concatenates without spaces
• Confusing variable interpolation syntax
• Expecting Blade syntax inside @php block

4. Identify the error in this Blade template code:

@php
  $name = 'Alice'
  echo "Hello, $name!";
@endphp

medium

A. Missing semicolon after variable assignment

B. Incorrect use of double quotes

C. Missing @endphp directive

D. Variable name not allowed in Blade

Solution

1. Step 1: Check PHP syntax inside @php block

   PHP requires semicolons after statements; the assignment line lacks one.

2. Step 2: Confirm other syntax correctness

   Double quotes and variable usage are correct; @endphp is present.

3. Final Answer:

   Missing semicolon after variable assignment -> Option A

4. Quick Check:

   Every PHP statement needs a semicolon [OK]

Hint: Check semicolons after each PHP statement [OK]

Common Mistakes:

• Forgetting semicolon after variable assignment
• Assuming Blade handles PHP syntax errors
• Missing closing @endphp tag

5. You want to display a list of users with their ages using raw PHP inside a Blade template. Which code correctly uses @php to loop through $users = [['name' => 'Bob', 'age' => 25], ['name' => 'Sue', 'age' => 30]]; and echo each user's name and age?

hard

A. @php
foreach ($users as $user) {
echo 'Name: $user[name], Age: $user[age]';
}
@endphp

B. @php
foreach ($users as $user) {
echo "Name: {$user['name']}, Age: {$user['age']}";
}
@endphp

C. @php
foreach ($users as $user) {
echo "Name: $user->name, Age: $user->age";
}
@endphp

D. @php
foreach ($users as $user) {
echo "Name: $user[name], Age: $user[age]";
}
@endphp

Solution

1. Step 1: Understand the data structure

   $users is an array of associative arrays, so access uses square brackets with quotes.

2. Step 2: Check string interpolation syntax

   @php foreach ($users as $user) { echo "Name: {$user['name']}, Age: {$user['age']}
   "; } @endphp correctly uses curly braces around array keys inside double quotes for interpolation.

3. Final Answer:

   @php foreach ($users as $user) { echo "Name: {$user['name']}, Age: {$user['age']}<br>"; } @endphp -> Option B

4. Quick Check:

   Use {$array['key']} inside double quotes for correct interpolation [OK]

Hint: Use curly braces for array keys inside double quotes [OK]

Common Mistakes:

• Using single quotes with variables inside (no interpolation)
• Accessing arrays as objects ($user->name) when they are arrays
• Not using curly braces for array keys inside strings
