What is the output of this Blade snippet using @php?

Consider this Blade template snippet:

@php
  $count = 3;
  echo "Count is: $count";
@endphp

What will be rendered on the page?

Laravel

@php
  $count = 3;
  echo "Count is: $count";
@endphp

A Count is: 3

B

@php
  $count = 3;
  echo "Count is: $count";
@endphp

C Count is: $count

D Error: Undefined variable

💡 Hint

Remember that @php allows you to write raw PHP code inside Blade templates.

The @php directive runs the PHP code inside it. The echo outputs the string with the variable value, so the rendered output is 'Count is: 3'.

📝 Syntax

Which option correctly uses @php to define and display a variable?

You want to define a variable $name with value 'Alice' and display it inside a Blade template using @php. Which snippet is correct?

A

@php
  echo $name = 'Alice';
@endphp

B

@php
  $name = 'Alice';
  echo $name;
@endphp

C

@php
  $name = 'Alice'
  echo $name;
@endphp

D

@php
  $name = 'Alice';
  echo '$name';
@endphp

💡 Hint

Check for proper PHP syntax and how variables are echoed.

Option B correctly defines $name and echoes it. Option B echoes assignment but is less clear. Option B misses a semicolon causing syntax error. Option B echoes the string '$name' literally, not the variable value.

Why does this Blade template cause an error?

Given this Blade snippet:

@php
  $total = 5
  echo $total;
@endphp

What is the cause of the error?

Laravel

@php
  $total = 5
  echo $total;
@endphp

A Missing semicolon after assigning $total

B echo cannot be used inside @php

C Variable $total is undefined

D Blade does not support @php directive

💡 Hint

Check PHP syntax rules inside @php blocks.

PHP requires semicolons at the end of statements. Missing semicolon after '$total = 5' causes a syntax error.

What is the output after this Blade snippet runs?

Analyze this Blade code:

@php
  $x = 10;
  $x += 5;
  echo $x;
@endphp

What will be displayed?

Laravel

@php
  $x = 10;
  $x += 5;
  echo $x;
@endphp

A Error: Undefined variable

B 10

C 5

D 15

💡 Hint

Remember how += operator works in PHP.

The variable $x starts at 10, then 5 is added, so echo outputs 15.

What is a key benefit of using @php directive in Blade templates?

Why would a developer choose to use the @php directive inside a Blade template instead of writing pure PHP tags ?

A @php automatically escapes all output for security

B @php runs PHP code on the client side for faster rendering

C @php integrates better with Blade syntax and avoids conflicts with Blade's own tags

D @php disables PHP error reporting inside Blade templates

💡 Hint

Think about how Blade templates handle PHP code and syntax conflicts.

The @php directive is designed to work smoothly inside Blade templates without conflicting with Blade's own syntax, unlike raw PHP tags which can cause parsing issues.
