shift moves the parameters so that $2 is now $1,etc. $@
PHP Code:
Inside double quote marks (" "), parameter and command substitution occur and \ quotes the characters \, `, ", and $. A $ in front of a double quoted string will be ignored in the "C" or "POSIX" locale, and may cause the string to be replaced by a locale specific string otherwise. The meaning of $* and $@ is identical when not quoted or when used as a variable assignment value or as a file name. However, when used as a command argument, "$*" is equivalent to "$1d $2d . . .", where d is the first character of the IFS variable, whereas "$@" is equivalent to "$1" "$2" . . . . Inside grave quote marks (` `), \ quotes the characters \, `, and $. If the grave quotes occur within double quotes, then \ also quotes the character ".

Perl::Critic::Policy::ValuesAndExpressions::ProhibitInteUseraContribPerl::Critic::Policy::ValuesAndExpressions::ProhibitInterpolationOfLiterals(3)NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitInterpolationOfLiterals - Always use single quotes for literal strings.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Don't use double-quotes or "qq//" if your string doesn't require interpolation. This saves the interpreter a bit of work and it lets the
reader know that you really did intend the string to be literal.
print "foobar"; #not ok
print 'foobar'; #ok
print qq/foobar/; #not ok
print q/foobar/; #ok
print "$foobar"; #ok
print "foobar
"; #ok
print qq/$foobar/; #ok
print qq/foobar
/; #ok
print qq{$foobar}; #preferred
print qq{foobar
}; #preferred
Use of double-quotes might be reasonable if the string contains single quote (') characters:
print "it's me"; # ok, if configuration flag set
CONFIGURATION
The types of quoting styles to exempt from this policy can be configured via the "allow" option. This must be a whitespace-delimited
combination of some or all of the following styles: "qq{}", "qq()", "qq[]", and "qq//".
This is useful because some folks have configured their editor to apply special syntax highlighting within certain styles of quotes. For
example, you can tweak "vim" to use SQL highlighting for everything that appears within "qq{}" or "qq[]" quotes. But if those strings are
literal, Perl::Critic will complain. To prevent this, put the following in your .perlcriticrc file:
[ValuesAndExpressions::ProhibitInterpolationOfLiterals]
allow = qq{} qq[]
The flag "allow_if_string_contains_single_quote" permits double-quoted strings if the string contains a single quote (') character. It
defaults to off; to turn it on put the following in your .perlcriticrc file:
[ValuesAndExpressions::ProhibitInterpolationOfLiterals]
allow_if_string_contains_single_quote = 1
