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!

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed	if  necessary  and
       fed to grep.

       If  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
