使用Composer的TCPDF Hello世界示例

Question

What is the minimum "hello world" example for TCPDF?

I see over 60 examples at https://tcpdf.org/examples/ and none of them work with composer and they are all very complicated.

I'm looking for something simple so I can start learning off of that.

The title of the post specifies that they want to use TCPDF with Composer and I found that the accepted answer does not utilize Composer to do this.

First, include TCPDF in Composer. Add the following code to your composer.json file:

"require": {
    "tecnickcom/tcpdf": "^6.2.13"
}

If there is an existing composer.lock file in the directory, then run from the command-line:

composer install

Otherwise, run from the command-line:

composer update

Create a PHP file with the following code:

<?php
// Load autoloader (using Composer)
require __DIR__ . '/vendor/autoload.php';
$pdf = new TCPDF();                 // create TCPDF object with default constructor args
$pdf->AddPage();                    // pretty self-explanatory
$pdf->Write(1, 'Hello world');      // 1 is line height

$pdf->Output('hello_world.pdf');    // send the file inline to the browser (default).

?>

Open this page from your web browser and you should see an example PDF document saying Hello World.
