Eh, I think that function won't do what you want.
Try this:

PHP код:

ReplaceNewString(string[])
{
    for(new i;strlen(string) < i;i++)
    {
        if(string[i] == '|' && string[i+1] == 'n')string[i] = '\';
        else if(string[i] == '\' && string[i+1] == 'n')string[i] = '|';
    }
} 


So you can convert "\n" into "|n" and you can save this into your mysql database. When you read this and save it in a string you convert it to "\n" back.
