Answer 1

You have to escape it. If you want a newline in Mysql, send \\n to the server, if you want a \\n , send \\\\n

Answer 2

If you want the \\n to appear inside the DB as is (ie. as \\ followed by n and not as a newline), then you have to escape it, so you have to send \\\\n is used for a new line to the DB.

BTW You could also use file_get_contents if you just want to read the full file contents into a string.

Answer 3

尝试查看PHP手册中的mysql_real_escape_string，以将输入转义到mysql数据库中。
