php显示遇到一个非常奇怪的问题。
我是用阿里云的ocr识别护照，
http://ocr.web.xinet.com.cn/huzhao.php
打开来，显示如下
{"algo_version":"2375eb78d7d5bdaa14f65f4597d87dcca1a833bf;0c879a80496474870d0b1ff89f9c58fe6a53651d","data":{"birthDate":"1976.03.23","birthPlace":"安徽/ANHUI","countryCode":"CHN","issueAuthority":"中华人民共和国国家移民管理局","issueDate":"2023.06.07","issuePlace":"上海/SHANGHAI","mrzLine1":"POCHNLU<
显示不全，然后我查看源代码
