does mysql database accept character ‘\’?

I save a file directory into mysql database, the directory string looks like:
“…my0my1file.txt”

character ‘‘ above is in C or jave meaning, called escape character.

Actually I use C++ to insert the string into mysql database – I guess php has same issue of this.

But when I read the string from database, escape character ‘‘ disappeared, the directory string looks like:

“…my0my1file.txt”

Now I have to change ‘‘ to ‘/’, so the insert string is “…my0/my1/file.txt”, reading string is fine and is the same as inserted.

my question is:
does mysql database accept character ‘‘? why does ‘‘ disappear? have you met same problem in php program?

How to solve the problem? I like using raw character ‘‘ than modified character ‘/’.

Thanks

Also in #PHP _↴
