php BOM 问题
最近合作开发项目 ?总发现php输出的不对 ?代码一模一样也不行 ?后来机智的我感觉是编码有问题 ?发现都是utf-8 的 ? 最后把文件内容都删除之后发现还有3个字符大小 ?用vim -b 命令打开之后发现是
?
后来才发现 这是utf-8里面的 BOM ?， 恶心的是BOM 会随着echo 输出 ?导致不对。
?
附上几个命令 查找和去除BOM
在vim 中:
#设置UTF-8编码:set fileencoding=utf-8#添加BOM:set bomb#删除BOM:set nobomb#查询BOM:set bomb?
??
grep:
// 查找grep -I -r -l $'\xEF\xBB\xBF' /path//替换grep -I -r -l $'\xEF\xBB\xBF' /path | xargs sed -i 's/^\xEF\xBB\xBF//g'
