You have extra spaces in there which grep will attempt to match literally.

Code:
#wrong
grep -E "PHRASE1 | PHRASE2" "$line"
# right
grep -E "PHRASE1|PHRASE2" "$line"

Otherwise, I don't see anything wrong with it.

Code:
while read line
do
  [ -f "$line" ] && grep -E "a|b|c|d" "$line" || echo "It is not an file"
done < infile

you're right. i had extra spaces. thanks!

zfgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
