Convert HTML to PDF in PHP

Quick Start with cURL

<?php
$ch = curl_init();

curl_setopt_array($ch, [
    CURLOPT_URL => 'https://html2pdfapi.com/render',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer YOUR_API_KEY',
        'Content-Type: application/json'
    ],
    CURLOPT_POSTFIELDS => json_encode([
        'html' => '<h1>Hello World</h1>',
        'format' => 'pdf'
    ])
]);

$response = curl_exec($ch);
curl_close($ch);

file_put_contents('output.pdf', $response);

Using Guzzle

<?php
use GuzzleHttp\Client;

$client = new Client();

$response = $client->post('https://html2pdfapi.com/render', [
    'headers' => [
        'Authorization' => 'Bearer ' . env('HTML2PDFAPI_KEY'),
        'Content-Type' => 'application/json'
    ],
    'json' => [
        'html' => '<h1>Hello World</h1>',
        'format' => 'pdf',
        'options' => [
            'format' => 'A4',
            'printBackground' => true
        ]
    ]
]);

$pdfContent = $response->getBody()->getContents();

Laravel Integration

<?php
// app/Http/Controllers/PdfController.php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;

class PdfController extends Controller
{
    public function generate(Request $request)
    {
        $html = view('invoices.template', [
            'invoice' => $request->invoice
        ])->render();

        $response = Http::withHeaders([
            'Authorization' => 'Bearer ' . config('services.html2pdfapi.key')
        ])->post('https://html2pdfapi.com/render', [
            'html' => $html,
            'format' => 'pdf'
        ]);
