解析短码到阵列

Question

我需要解析WordPress的短码到阵，在PHP，例如：

[parrent_shortcode attribute='1' attribute2='a'] 
    [shortcode atrribute1=true attribute2=true]This is first content[/shortcode] 
    [shortcode atrribute1=false]This is second content[/shortcode] 
[/parrent_shortcode] 

成为：

Array(
    [name] => 'parrent_shortcode' 
    [atts] => Array(
     [attribute] => '1' 
     [attribute2] => 'a' 
    ) 
    [content] => Array(
     [child1] => Array(
      [name] => 'shortcode' 
      [atts] => Array(
       [atrribute1] => true 
       [attribute2] => true 
      ) 
      [content] => 'This is first content' 
     ) 
     [child2] => Array(
      [name] => 'shortcode' 
      [atts] => Array(
       [atrribute1] => false 
      ) 
      [content] => 'This is second content' 
     ) 
    ) 
) 

此外简码可以没有parrent包装，并且可以是单（自闭）没有内容。此外，属性中可以有空格。

我尝试用爆炸完成，但疗法有这么多的组合..

function get_pattern($text) { 
    $pattern = get_shortcode_regex(); 
    preg_match_all("/$pattern/s", $text, $c); 
    return $c; 
} 

function parse_atts($content) { 
    $content = preg_match_all('/([^ ]*)=(\'([^\']*)\'|\"([^\"]*)\"|([^ ]*))/', trim($content), $c); 
    list($dummy, $keys, $values) = array_values($c); 
    $c = array(); 
    foreach ($keys as $key => $value) { 
     $value = trim($values[ $key ], "\"'"); 
     $type = is_numeric($value) ? 'int' : 'string'; 
     $type = in_array(strtolower($value), array('true', 'false')) ? 'bool' : $type; 
     switch ($type) { 
      case 'int': $value = (int) $value; break; 
      case 'bool': $value = strtolower($value) == 'true'; break; 
     } 
     $c[ $keys[ $key ] ] = $value; 
    } 
    return $c; 
} 

function the_shortcodes(&$output, $text, $child = false) { 

    $patts = get_pattern($text); 
    $t = array_filter(get_pattern($text)); 
    if (! empty($t)) { 
     list($d, $d, $parents, $atts, $d, $contents) = $patts; 
     $out2 = array(); 
     $n = 0; 
     foreach($parents as $k=>$parent) { 
      ++$n; 
      $name = $child ? 'child' . $n : $n; 
      $t = array_filter(get_pattern($contents[ $k ])); 
      $t_s = the_shortcodes($out2, $contents[ $k ], true); 
      $output[ $name ] = array('name' => $parents[ $k ]); 
      $output[ $name ]['atts'] = parse_atts($atts[ $k ]); 
      $output[ $name ]['original_content'] = $contents[ $k ]; 
      $output[ $name ]['content'] = ! empty($t) && ! empty($t_s) ? $t_s : $contents[ $k ]; 
     } 
    } 
    return array_values($output); 
} 

用法：

$text = "[parrent_shortcode attribute='1' attribute2='a b c'] 
    [shortcode atrribute1=true attribute2=\"j'aime\"]This is first content[/shortcode] 
    [shortcode atrribute1=false]This is [shortcode/] content[/shortcode] 
[/parrent_shortcode] 
"; 
$output = array(); 
$output = the_shortcodes($output, $text); 
var_dump(array_values($output)); 

此相呼应：

array (
    0 => 
    array (
    'name' => 'parrent_shortcode', 
    'atts' => 
    array (
     'attribute' => 1, 
     'attribute2' => 'a b c', 
    ), 
    'original_content' => ' 
    [shortcode atrribute1=true attribute2="j\'aime"]This is first content[/shortcode] 
    [shortcode atrribute1=false]This is [shortcode/] content[/shortcode] 
', 
    'content' => 
    array (
     'child1' => 
     array (
     'name' => 'shortcode', 
     'atts' => 
     array (
      'atrribute1' => true, 
      'attribute2' => 'j\'aime', 
     ), 
     'original_content' => 'This is first content', 
     'content' => 'This is first content', 
    ), 
     'child2' => 
     array (
     'name' => 'shortcode', 
     'atts' => 
     array (
      'atrribute1' => false, 
     ), 
     'original_content' => 'This is [shortcode/] content', 
     'content' => 
     array (
      0 => 
      array (
      'name' => 'shortcode', 
      'atts' => 
      array (
      ), 
      'original_content' => '', 
      'content' => '', 
     ), 
     ), 
    ), 
    ), 
), 
)

的简码API提供了一个名为do_shortcode函数（） - 这是否你想要做什么？ 该函数定义如下：http://core.trac.wordpress.org/browser/tags/3.6.1/wp-includes/shortcodes.php#L181

也或许看get_shortcode_regex（），其定义如下：http://core.trac.wordpress.org/browser/tags/3.6.1/wp-includes/shortcodes.php#L211 你应该能够挖掘出以某种方式解析简码的正则表达式。
