perl用{}修饰变量名的写法分享
简介复制代码 代码如下:sub test { my $head = "abc"; my $tail = "def"; my $full = "${head}_${tail}"; print $full, "\n";} 直接写成下面这样,在strict模式下是无法通过的。复制代码
复制代码 代码如下:
sub test {
my $head = "abc";
my $tail = "def";
my $full = "${head}_${tail}";
print $full, "\n";
}
直接写成下面这样,在strict模式下是无法通过的。
复制代码 代码如下:
my $full = "$head_$tail";
sub test {
my $head = "abc";
my $tail = "def";
my $full = "${head}_${tail}";
print $full, "\n";
}
