php解析http获取的json字符串变量总是空白null
php解析http获取的json字符串变量总是空白null
这篇文章主要介绍了php解析http获取的json字符串变量总是空白null的解决方法,个人经验的总结,这里推荐给大家。
今天同事项目中遇到一个问题,通过http接口获取的json字符串使用json_decode始终无法正确解析,返回空白。
直接把结果字符串复制出来手动创建一个变量却正常,在前端js也能解析,搞了半天不得其解,借助强大的谷歌解决了问题,答案是接口吐出的结果包含有BOM头,BOM头这个东西可谓是php的死敌啊
不说了,直接上解决办法:
代码如下:
if (substr($return, 0,3) == pack("CCC",0xef,0xbb,0xbf)) {
$return = substr($return, 3);
}
$data = json_decode($return,true);
这里记录一下,分享给大家,希望对大家能够有所帮助。
