Hi Amol, I can tell you that this worked in JAVA sample of add campaign targeting :
private static CampaignCriterion buildLanguageCriterion(String campaignResourceName){ Builder builder = CampaignCriterion.newBuilder().setCampaign(campaignResourceName); builder.setLanguage(LanguageInfo.newBuilder().setLanguageConstant("languageConstants/1019").build()) ; return builder.build(); } I can guess that this would work in the PHP sample of add campaign targeting : private static function createLanguageCampaignCriterionOperation( string $campaignResourceName ){ $campaignCriterion = new CampaignCriterion([ // Creates a location using the specified location ID. 'language' => new LanguageInfo([ 'language_constant' => ResourceNames::forLanguageConstant(1019) ]), 'campaign' => $campaignResourceName ]); return new CampaignCriterionOperation(['create' => $campaignCriterion]); } And adding in above : self::createProximityCampaignCriterionOperation($campaignResourceName), self::createLanguageCampaignCriterionOperation($campaignResourceName) To be certain you may reach out to the PHP library issue tracker.
