Of course it does. You are trying to replace all the strings that match $a
with "\" in an empty string ("").

To quote the webpage:
# str_replace — Replace all occurrences of the search string with the
# replacement string
# Description
# mixed str_replace ( mixed $search , mixed $replace , mixed $subject
# [, int &$count ] )
#
# This function returns a string or an array with all occurrences of search
# in subject replaced with the given replace value.
Note that "search" is the first parameter, "replace" is the second,
and "subject" is the third.
So, your
str_replace($a,"\","");
will return a string or array with all occurrences of
the contents of $a
in
""
with the given
"\"
value
What you apparently want is
str_replace("\","",$a);
