PHP：在php脚本中显示图像

Question

我想将这个<img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" />实现为以下函数。

function list_my_categories($exclude = '') { 
    if (!empty($exclude)) { 
     $exclude = 'exclude=' . $exclude; 
    } 
    $categories = get_categories($exclude); 
    $html = ''; 

    foreach ($categories as $cat) { 
      if($cat->category_parent == 0) { 
      <img src="<?php echo z_taxonomy_image_url($cat->term_id); ?>" /> 
       $html .= '<p>' . $cat->cat_name . '</p>'; 
           $html .= '<p>' . $cat->category_description . '</p>'; 
       $childcategories = get_categories('child_of='.$cat->cat_ID.''); 
         if(!empty($childcategories)){ 
        foreach ($childcategories as $ccat) { 
        $html .= '<p>' . $ccat->cat_name . '</p>'; 
           $html .= '<p>' . $ccat->category_description . '</p>'; 
         } 
         } 
       } 
    } 

    return $html; 
} 
add_shortcode('show-cats', 'list_my_categories'); 

功能将显示在WordPress的类别列表，我有另外一个插件，它允许您设置图像的每个类别，所以我试图证明它...

if($cat->category_parent == 0) 
{ 
    $html .= '<img src="' . z_taxonomy_image_url($cat->term_id) . '" />'; 
    $html .= '<p>' . $cat->cat_name . '</p>'; 
    $html .= '<p>' . $cat->category_description . '</p>'; 
    $childcategories = get_categories('child_of='.$cat->cat_ID.''); 
    if(!empty($childcategories)) 
    { 
     foreach ($childcategories as $ccat) 
     { 
      /*$html .= '<img src="' . z_taxonomy_image_url($ccat->term_id) . '" />';*/ 
      $html .= '<p>' . $ccat->cat_name . '</p>'; 
      $html .= '<p>' . $ccat->category_description . '</p>'; 
     } 
    } 
}
