strip c slashes（）功能确实如此：

  stripcslashes（ 'foo\r\\\
'）; 
 

I'm working with a mysqldump file that has escaped character sequences. I need to know the length of a string as its database value, but the dump has escape characters in it, which add length to the string.

I've used stripslashes() which properly un-escapes single- and double-quotes, but it doesn't touch the \r\n.

I'm concerned there are other escaped character sequences in there that I'm not aware of. Is there a function I can use that will give me the true length of the string as it would be in the database? If I have to build my own function, what other sequences should it handle?

The strip c slashes() function does exactly that:

stripcslashes('foo\r\n');
