List 循环

Testing Is Documentation

tests/View/Compiler/CompilerListTest.phpList 循环 - 图1

list 标签也是用于循环输出,解析后的本质为 foreach,同时 foreach 比较符合大家的习惯。

code

  1. public function testCode(): void
  2. {
  3. $parser = $this->createParser();
  4. $source = <<<'eot'
  5. {list $list $key $value}
  6. {$key} - {$value}
  7. {/list}
  8. eot;
  9. $compiled = <<<'eot'
  10. <?php if (is_array($list)): foreach($list as $key => $value): ?>
  11. <?php echo $key; ?> - <?php echo $value; ?>
  12. <?php endforeach; endif; ?>
  13. eot;
  14. $this->assertSame($compiled, $parser->doCompile($source, null, true));
  15. }

code 省略键值

有时候我们不需要键值,这个时候我们在模板中写下如下的代码:

  1. public function testCodeFull(): void
  2. {
  3. $parser = $this->createParser();
  4. $source = <<<'eot'
  5. {list $list $value}
  6. {$value}
  7. {/list}
  8. eot;
  9. $compiled = <<<'eot'
  10. <?php if (is_array($list)): foreach($list as $value): ?>
  11. <?php echo $value; ?>
  12. <?php endforeach; endif; ?>
  13. eot;
  14. $this->assertSame($compiled, $parser->doCompile($source, null, true));
  15. }

node

  1. public function testNode(): void
  2. {
  3. $parser = $this->createParser();
  4. $source = <<<'eot'
  5. <list for=list value=my_value key=my_key index=my_index>
  6. {$my_index} {$my_key} {$my_value}
  7. </list>
  8. eot;
  9. $compiled = <<<'eot'
  10. <?php $my_index = 1; ?>
  11. <?php if (is_array($list)): foreach ($list as $my_key => $my_value): ?>
  12. <?php echo $my_index; ?> <?php echo $my_key; ?> <?php echo $my_value; ?>
  13. <?php $my_index++; ?>
  14. <?php endforeach; endif; ?>
  15. eot;
  16. $this->assertSame($compiled, $parser->doCompile($source, null, true));
  17. }
