Raw PHP in Blade (@php) in Laravel - Step-by-Step Execution

Concept Flow - Raw PHP in Blade (@php)

Start Blade Template

↓

Encounter @php block

↓

Execute PHP code inside block

↓

Output or store results

↓

Continue rendering Blade template

↓

End Template Rendering

Blade template engine reads the @php block, runs the PHP code inside, then continues rendering the rest of the template.

Execution Sample

Laravel

@php
  $greeting = 'Hello, world!';
@endphp
<p>{{ $greeting }}</p>

This code runs raw PHP inside Blade to set a variable, then outputs it in HTML.

Execution Table

Step	Action	PHP Code Executed	Variable State	Output Produced
1	Enter @php block	No PHP code executed yet	$greeting = undefined	No output
2	Execute PHP code	$greeting = 'Hello, world!';	$greeting = 'Hello, world!'	No output
3	Exit @php block	End of PHP block	$greeting = 'Hello, world!'	No output
4	Render <p> tag with Blade echo	Echo $greeting	$greeting = 'Hello, world!'	<p>Hello, world!</p>
5	Finish template	No PHP	$greeting = 'Hello, world!'	Full HTML output

💡 Template rendering completes after processing @php block and outputting variable.

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	Final
$greeting	undefined	undefined	'Hello, world!'	'Hello, world!'	'Hello, world!'

Key Moments - 2 Insights

Why doesn't the @php block directly output anything?

Because @php runs raw PHP code without echoing; output happens only when Blade echoes variables like {{ $greeting }} as shown in step 4.

Can variables set inside @php be used later in the template?

Yes, variables set inside @php persist and can be used anywhere later in the Blade template, as seen with $greeting in step 4.

Visual Quiz - 3 Questions

Look at the execution table, what is the value of $greeting after step 2?

A undefined

B 'Hello, world!'

C null

D Empty string

💡 Hint

Check the 'Variable State' column at step 2 in the execution table.

At which step does the template produce visible HTML output?

A Step 4

B Step 3

C Step 1

D Step 5

💡 Hint

Look at the 'Output Produced' column to find when HTML appears.

If you remove the @endphp tag, what happens to the execution flow?

A PHP code runs normally

B Variables are still set but output is empty

C Blade throws a syntax error and stops rendering

D Template skips the PHP code

💡 Hint

Blade requires @endphp to close the PHP block; missing it breaks the template parsing.

Concept Snapshot

@php ... @endphp lets you run raw PHP inside Blade templates.
Variables set inside @php persist for later use.
No output happens inside @php unless you echo explicitly.
Use {{ }} to output variables safely.
Always close @php blocks with @endphp.

Full Transcript

In Laravel Blade templates, the @php directive allows you to write raw PHP code inside your template. When the Blade engine encounters @php, it executes the PHP code inside the block without producing output unless you explicitly echo something. Variables defined inside this block remain available for the rest of the template. After the @php block ends with @endphp, Blade continues rendering the template, and you can output variables using the {{ }} syntax. This flow ensures you can mix PHP logic and HTML cleanly. Remember to always close your @php blocks to avoid syntax errors.
