PHP BOM Issues

Recently co-development projects always found that the PHP output is not the same as the code is not the same as the wit I feel that the code has a problem to find all the Utf-8 the last file content is deleted after the discovery of 3 character size with the Vim-b command opened and found that the feeling of the problem is here.

Later found that this is utf-8 inside the BOM, disgusting is the BOM will be with the echo output caused by the wrong.

Attach several commands to find and remove BOM

In Vim:

Java code

#设置UTF-8 encoding

: Set Fileencoding=utf-8

#添加BOM

: Set Bomb

#删除BOM

: Set Nobomb

#查询BOM

: Set bomb?

Grep:

Java code

Find

Grep-i-r-l $ ' \xef\xbb\xbf '/path

Replace

Grep-i-r-l $ ' \xef\xbb\xbf '/path | Xargs sed-i ' s/^\xef\xbb\xbf//g '
