一、变量输出 （重点）
1.标量输出
2.数组输出
{$name[1]}
{$name['k2']}
{$name.k1}
3.对象输出
{$name:k}
{$name->k}
二、系统变量
{$Think.get.id}
三、使用函数
{$name|strtoupper} 生成的编译后文件是 <?php echo (strtoupper($name)); ?>
{$name|date='Y m d H:i:s',###}
四、默认值
{$name|default='这里是默认值'}
五、运算符
+ - * / % ++ --
{$name++}
perl 的一些数据结构:
zjzc01:/root/test# cat s1.pl
##数组
print "数组
";
@arr=qw/a1 a2 a3 a4/;
print $arr[0]."
";
print $arr[1]."
";
print "hash
";
##hash
%hash=(a=>1,b=>2,c=>3);
print $hash{a}."
";
print $hash{b}."
";
##数组引用
print "数组引用
";
$arr=[a1,a2,a3,a4];
print $arr->[0]."
";
print $arr->[1]."
";
##hash引用
print "hash 引用
";
$hash={a=>1,b=>2,c=>3};
print $hash->{a}."
";
print $hash->{b}."
";
zjzc01:/root/test# perl s1.pl
