ブログに DeepL API を導入してみました。

Terminal
composer require deeplcom/deepl-php

PHP
require_once __DIR__ . '/vendor/autoload.php';
$translator = new \DeepL\Translator(AUTH_KEY);

$options = [];
$options['tag_handling'] = 'html';
$options['split_sentences'] = '1';
// $options['glossary'] = $glossaryId;

$contents = [
'おはようございます',
'こんばんは',
'さようなら',
];

try {
	$results = $translator->translateText($contents, 'ja', 'en-US', $options);

	if (! empty($results)) {
		foreach ($results as $value) {
			echo $value->text , '<br>';
		}
	}
} catch (\DeepL\DeepLException $error) {
	echo ($error->getMessage() ?? 'unknown error');
}

PHP
require_once __DIR__ . '/vendor/autoload.php';
$translator = new \DeepL\Translator(AUTH_KEY);

// DELETE
$glossaries = $translator->listGlossaries();
foreach ($glossaries as $glossary) {
	$translator->deleteGlossary($glossary);
}

// CREATE
$myCsvGlossary = $translator->createGlossaryFromCsv(
'jatoen',
'ja',
'en',
file_get_contents(__DIR__ . '/jatoen.csv')
);

$myCsvGlossary = $translator->createGlossaryFromCsv(
'entoja',
'en',
'ja',
file_get_contents(__DIR__ . '/entoja.csv')
);

$glossaries = $translator->listGlossaries();

foreach ($glossaries as $glossary) {
	$glossary->glossaryId;
	$glossary->name;
}
