Anti-slash problem in SQL

I use the PHP5.5, query statement format as follows To_char (mydate,\ ' mm/dd/yyyy\ '), but the result of the returned data is 05\/27\/2014, how can I remove the backslash?

Thank you

How the TO_CHAR function is defined

How the TO_CHAR function is defined

Functions of SQL
$stid = Oci_parse ($conn, ' Select Birthplace,birthplacecode,myseq,to_char (mydate,\ ' mm/dd/yyyy\ ') as MyDate, Institution,institutioncode from Scott.mapaeon ');

I found that as long as there is/in the result of the query, a backslash will precede it, regardless of the type of data in the database

How can I get rid of the backslash in the result? Thank you
