ThinkPHP 3.1.2 模板中的变量

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\n";

@arr=qw/a1 a2 a3 a4/;

print $arr[0]."\n";

print $arr[1]."\n";

print "hash\n";

##hash

%hash=(a=>1,b=>2,c=>3);

print $hash{a}."\n";

print $hash{b}."\n";

##数组引用

print "数组引用\n";

$arr=[a1,a2,a3,a4];

print $arr->[0]."\n";

print $arr->[1]."\n";

##hash引用

print "hash 引用\n";

$hash={a=>1,b=>2,c=>3};

print $hash->{a}."\n";

print $hash->{b}."\n";

zjzc01:/root/test# perl s1.pl

数组

a1

a2

hash

数组引用

a1

a2

hash 引用

//关联数组输出:

    public function index(){

    //调用index.html模板文件

	//name表示标识

	$arr=array('k1'=>'scan1','k2'=>'scan2');

	$this->assign('name',$arr);

	$this->display();

    }

}
