You probably want a regular expression:

Code
if ($string =~ /[0-9|+]/) { 
  # $string contains a digit or a | or a + 
}

So if I want to validiate If string is only "|" sign I Write Like This :
if ($string =~ /[|]/) {
# $string contains only |
}
?

No, that would just check to see if $mystring contains a |, not neccessarily only a |. I think removing the brackets ([]) will check to see if it contains only a |.
