While 循环

Testing Is Documentation

tests/View/Compiler/CompilerWhileTest.php

QueryPHP 支持 while 语法标签，通过这种方式可以很好地将 PHP 的 while 语法布局出来。

node

public function testNode(): void
{
    $parser = $this->createParser();

    $source = <<<'eot'
        {{~ $i = 10 }}
        {% while cond="$i > 0" %}
            {{ $i }}Hello QueryPHP !<br>
            {{~ $i-- }}
        {% :while %}
        eot;

    $compiled = <<<'eot'
        <?php $i = 10; ?>
        <?php while($i > 0): ?>
            <?php echo $i; ?>Hello QueryPHP !<br>
            <?php $i--; ?>
        <?php endwhile; ?>
        eot;

    $this->assertSame($compiled, $parser->doCompile($source, null, true));
}

cond 可省略

默认第一个条件会自动解析为 cond。

public function testNodeSimple(): void
{
    $parser = $this->createParser();

    $source = <<<'eot'
        {{~ $i = 10 }}
        {% while "$i > 0" %}
            {{ $i }}Hello QueryPHP !<br>
            {{~ $i-- }}
        {% :while %}
        eot;

    $compiled = <<<'eot'
        <?php $i = 10; ?>
        <?php while($i > 0): ?>
            <?php echo $i; ?>Hello QueryPHP !<br>
            <?php $i--; ?>
        <?php endwhile; ?>
        eot;

    $this->assertSame($compiled, $parser->doCompile($source, null, true));
}
