Usage

Create an instance with your auth key:

$authKey = '<AUTH KEY>';
$deepl   = new DeepL($authKey);

Use the DeepL API Pro:

$authKey = '<AUTH KEY>';
$deepl   = new DeepL($authKey,2,'api.deepl.com');

Translate

Translate one Text:

$translatedText = $deepl->translate('Hallo Welt', 'de', 'en');
echo $translatedText[0]['text'].PHP_EOL;

Translate multiple Texts:

$text = array(
    'Hallo Welt',
    'Wie geht es dir',
    'Macht doch einfach mal'
);

$translations = $deepl->translate($text, 'de', 'en');

foreach ($translations as $translation) {
    echo $translation['text'].PHP_EOL;
}

param	Description
$text	Text to be translated. Only UTF8-encoded plain text is supported. The parameter may be specified as an Array and translations are returned in the same order as they are requested. Each of the array values may contain multiple sentences. Up to 50 texts can be sent for translation in one request.
$sourceLang	Language of the text to be translated. default: de
$targetLang	The language into which the text should be translated. default: en
$tagHandling	Sets which kind of tags should be handled. Options currently available: "xml"
$ignoreTags	Array of XML tags that indicate text not to be translated. default: null
$formality	Sets whether the translated text should lean towards formal or informal language. This feature currently works for all target languages except "EN" (English), "EN-GB" (British English), "EN-US" (American English), "ES" (Spanish), "JA" (Japanese) and "ZH" (Chinese). Possible options are: "default" (default) "more" - for a more formal language "less" - for a more informal language
$splitSentences	Array of XML tags which always cause splits default: null
$preserveFormatting	Sets whether the translation engine should respect the original formatting, even if it would usually correct some aspects. Possible values are: "0" (default) "1" The formatting aspects affected by this setting include: Punctuation at the beginning and end of the sentence Upper/lower case at the beginning of the sentence
$nonSplittingTags	Comma-separated list of XML tags which never split sentences. default: null
$outlineDetection	See: https://www.deepl.com/docs-api/handling-xml/outline-detection/ default: 1
$splittingTags	Array of XML tags which always cause splits. default: null

Supported languages

In Version 2 we removed the internal List of supported Languages. Instead, you can now get an array with the supported Languages directly form DeepL:

$languagesArray = $deepl->languages();

foreach ($languagesArray as $language) {
    echo 'Name: '.$language['name'].' Api-Shorthand: '.$language['language'].PHP_EOL;
}

You can check for the supported Source-Languages:

$sourceLanguagesArray = $deepl->languages('source');

foreach ($sourceLanguagesArray as $srouceLanguage) {
    echo 'Name: '.$srouceLanguage['name'].' Api-shorthand: '.$srouceLanguage['language'].PHP_EOL;
}

Check for the supported Target-Languages:

$targetLanguagesArray = $deepl->languages('target');

foreach ($targetLanguagesArray as $targetLanguage) {
    echo 'Name: '.$targetLanguage['name'].' Api-Shorthand: '.$targetLanguage['language'].PHP_EOL;
}

Monitoring usage

You can now check how much you translate, as well as the limit:

$usageArray = $deepl->usage();

echo 'You have used '.$usageArray['character_count'].' of '.$usageArray['character_limit'].' in the current billing period.'.PHP_EOL;

Glossary

Create a glossary

$glossary = $deepl->createGlossary('MyGlossary', ['Hallo' => 'Hello'], 'de', 'en');

param	Description
$name	Glossary name
$entries	Array of entries
$sourceLanguage	The source language into which the glossary rule apply
$targetLanguage	The target language into which the glossary rule apply

Delete a glossary

$glossary = $deepl->deleteGlossary($glossaryId);

param	Description
$glossaryId	Glossary uuid (set by DeepL when glossary is created)

List glossaries

$glossaries = $deepl->listGlossaries();
foreach ($glossaries as $glossary) {
    var_dump($glossary);
}

Get glossary meta information: creation date, is glossary ready to use ...

$glossaryInformation = $deepl->glossaryInformation($glossaryId);
var_dump($glossaryInformation);

param	Description
$glossaryId	Glossary uuid (set by DeepL when glossary is created)

Get glossary entries

$entries = $deepl->glossaryEntries($glossaryId);
foreach ($entries as $sourceLangText => $targetLangText) {
    echo $sourceLangText .' > '.$targetLangText;
}

param	Description
$glossaryId	Glossary uuid (set by DeepL when glossary is created)

Configuring cURL requests

If you need to use a proxy, you can configure the underlying curl client to use one. You can also specify a timeout to avoid waiting for several minutes if Deepl is unreachable

$deepl->setTimeout(10); //give up after 10 seconds
$deepl->setProxy('http://corporate-proxy.com:3128');
$deepl->setProxyCredentials('username:password');
