Question

目前我正在重建我的网站，我正在使用Wordpress自定义程序将一些主页特定数据设置到相应的部分。

我已经在Wordpress后端安装了数据，但是我在前端拆分时遇到了麻烦。

我能够在数组中获取所有Wordpress自定义程序值，并根据部分字符串的第一部分对其进行过滤。

例如，我使用以下php代码过滤我的时间轴项目：

<?php
    $home_options = get_theme_mods();

    foreach ($home_options as $key => $value) {
        if (strpos($key, "timeline_item") === 0) {
            echo '<strong>'.$key.'</strong> = '.$value.'<br />';
        }
    }
?>

这给了我以下数据：

timeline_item_1_enable = 1
timeline_item_1_title = Test item 1
timeline_item_1_duration = 2010 - 2014
timeline_item_1_text = Test item 1 text
timeline_item_2_enable = 1
timeline_item_2_title = Test item 2
timeline_item_2_duration = 2014 - 2014
timeline_item_2_text = Test item 2 text
timeline_item_3_enable = 1
timeline_item_3_title = Test item 3
timeline_item_3_duration = 2010 - 2014
timeline_item_3_text = Test item 3 text
timeline_item_4_enable = 1
timeline_item_4_title = Test item 1
timeline_item_4_duration = 2010 - 2014
timeline_item_4_text = Test item 4 text

这工作正常，我得到了我需要的所有时间线数据。但是，根据该数据，我想提取所有以timeline_item_1_开头的项目，并将它们捆绑到<div>，同样地timeline_item_2_等等

所以问题是，我如何进一步拆分结果数组，并根据字符串的第一部分捆绑所有彼此相关的项目，最终结果如下，

<div>
timeline_item_1_enable = 1
timeline_item_1_title = Test item 1
timeline_item_1_duration = 2010 - 2014
timeline_item_1_text = Test item 1 text
</div>
<div>
timeline_item_2_enable = 1
timeline_item_2_title = Test item 2
timeline_item_2_duration = 2014 - 2014
timeline_item_2_text = Test item 2 text
</div>
<div>
timeline_item_3_enable = 1
timeline_item_3_title = Test item 3
timeline_item_3_duration = 2010 - 2014
timeline_item_3_text = Test item 3 text
</div>
<div>
timeline_item_4_enable = 1
timeline_item_4_title = Test item 1
timeline_item_4_duration = 2010 - 2014
timeline_item_4_text = Test item 4 text
</div>

<?php
    $home_options = get_theme_mods();
    $regex = '/([a-z]*)_([a-z]*)_(\d)_([a-z]*)/';
    $parts = [];

    foreach ($home_options as $key => $value) {
       preg_match_all($regex, $key, $matches, PREG_SET_ORDER, 0);
       /* $matches have the matches below
       Full match   0-22    `timeline_item_1_enable`
       Group 1. 0-8 `timeline`
       Group 2. 9-13    `item`
       Group 3. 14-15   `1`
       Group 4. 16-22   `enable`
       */  
        $pkey = 'timeline_item_'.$matches[0][3]; 
        if (!isset($parts[$pkey])) $parts[$pkey] = array($key => $val);
        else $parts[$pkey][$key] = $val;
    }

    foreach($parts as $pkey => $props) {
      echo '<div>';
      foreach($props as $key => $val) {
        echo $key . ' = ' . $val . '<br>';
      } 
      echo '</div>';
    } 
?>

您可以使用array_chunk以保留键true分开四个数组，并在内循环中循环每组四个。

Foreach(array_chunk($arr, 4, true) as $val){
    Echo "<div>\n";
    Foreach($val as $key => $v){
        echo '<strong>'.$key.'</strong> = '.$v."<br />\n";
    }
    Echo "</div>\n";
}
