PHP函数运行时间

Question

样的一个基本问题，但我有类似于此示例页面：

<?php 
/* 
Template Name: Temp 
*/ 
?> 

<?php 
function myFunction($urls) { 
    $q = mysql_query("SELECT * FROM table"); 
    while ($row = mysql_fetch_array($q)) { 
     echo $row['field']; 
    } 
} 

$url1 = $_POST['urls']; 
$urls = explode("\r\n",$url1); 
?> 
<?php get_header(); ?> 
    <?php if (get_option('professional_integration_single_top') <> '' && get_option('professional_integrate_singletop_enable') == 'on') echo(get_option('professional_integration_single_top')); ?> 

    <div id="content-top" class="top-alt"></div> 
    <div id="content" class="clearfix content-alt"> 
     <div id="content-area"> 
     <?php if (have_posts()) : while (have_posts()) : the_post(); ?> 
      <?php get_template_part('includes/breadcrumbs'); ?> 

      <?php if (get_option('professional_integration_single_top') <> '' && get_option('professional_integrate_singletop_enable') == 'on') echo(get_option('professional_integration_single_top')); ?> 

      <div class="entry clearfix post"> 
      <?php 
         myFunction($urls);   
       ?> 
       <h1 class="title"><?php the_title(); ?></h1> 

       <?php if (get_option('professional_page_thumbnails') == 'on') { ?> 

        <?php $thumb = ''; 
        $width = 184; 
        $height = 184; 
        $classtext = ''; 
        $titletext = get_the_title(); 

        $thumbnail = get_thumbnail($width,$height,$classtext,$titletext,$titletext); 
        $thumb = $thumbnail["thumb"]; ?> 

        <?php if($thumb <> '') { ?> 
         <div class="thumb alignleft"> 
          <?php print_thumbnail($thumb, $thumbnail["use_timthumb"], $titletext, $width, $height, $classtext); ?> 
          <span class="overlay"></span> 
         </div> <!-- end .thumb --> 
        <?php }; ?> 

       <?php }; ?> 

       <?php the_content(); ?> 
       <?php wp_link_pages(array('before' => '<p><strong>'.esc_html__('Pages','Professional').':</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?> 
       <?php edit_post_link(esc_html__('Edit this page','Professional')); ?> 

      </div> <!-- end .entry --> 

      <?php if (get_option('professional_integration_single_bottom') <> '' && get_option('professional_integrate_singlebottom_enable') == 'on') echo(get_option('professional_integration_single_bottom')); ?> 

      <?php if (get_option('professional_show_pagescomments') == 'on') comments_template('', true); ?> 
     <?php endwhile; endif; ?> 
     </div> <!-- end #content-area --> 

     <?php get_sidebar(); ?> 

    </div> <!-- end #content --> 
    <div id="content-bottom" class="bottom-alt"></div> 

<?php get_footer(); ?> 

编辑：

我已经更新了代码，以反映确切的代码我使用。

为什么someFunction函数中的myFunctionecho输出出现在文档的底部，而不是$somestring之后？

如何更改此代码，以便myFunctionecho输出显示在正确的位置？

我相信它跟你的Wordpress主题有关。我在我的WordPress博客上测试过它，效果很好。函数在我执行它的地方回显值。请检查您的header.php。我认为d3v3us是正确的，并且与输出缓冲有关。
