变量赋值

Testing Is Documentation

tests/View/Compiler/CompilerAssignTest.php变量赋值 - 图1

可以在模板中进行一些变量的赋值，以便于进行后续计算处理。

node 版本

assign 标签也是用于页面快捷赋值，这个还是用起来比较方便。

  1. public function testBaseUse(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         <assign name="helloWorld" value="say hello to the world" />
  7.         <assign name="test.hello" value="hello" />
  8.         eot;
  10.     $compiled = <<<'eot'
  11.         <?php $helloWorld = 'say hello to the world'; ?>
  12.         <?php $test->hello = 'hello'; ?>
  13.         eot;
  15.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  16. }

node 版本.初始化为 Null 值

  1. public function testNode(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         <assign name="test.hello" />
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $test->hello = null; ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

node 版本.初始化为指定变量

  1. public function testNode2(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         <assign name="test.hello" value="$hello" />
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $test->hello = $hello; ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

node 版本.初始化为函数格式化变量

  1. public function testNode3(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         <assign name="test.hello" value="$hello|md5" />
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $test->hello = md5($hello); ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

node 版本.初始化为函数格式化占位变量

  1. public function testNode4(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         <assign name="test.hello" value="$hello|test=0,1|foo=**" />
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $test->hello = foo(test($hello, 0,1)); ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

JS 风格版本

  1. public function testLet(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         {% let foo = 'foo' %}
  7.         {% let hello = hello . 'foo' %}
  8.         eot;
  10.     $compiled = <<<'eot'
  11.         <?php $foo = 'foo'; ?>
  12.         <?php $hello = $hello . 'foo'; ?>
  13.         eot;
  15.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  16. }

JS 风格版本.初始化值

  1. public function testLet2(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         {% let foo 'foo' %}
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $foo = 'foo'; ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

JS 风格版本.初始化为 Null 值

  1. public function testLet3(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         {% let foo %}
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $foo = null; ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }

JS 风格版本.初始化为 Null 值带上等于符

  1. public function testLet4(): void
  2. {
  3.     $parser = $this->createParser();
  5.     $source = <<<'eot'
  6.         {% let foo = %}
  7.         eot;
  9.     $compiled = <<<'eot'
  10.         <?php $foo = null; ?>
  11.         eot;
  13.     $this->assertSame($compiled, $parser->doCompile($source, null, true));
  14. }
