Question

我现在有以下代码，我想简单地添加“CAPTION”文本所在的EXIF标题数据。我怎么做？我知道如何获取数据，但我不确定如何将它添加到我已经进行的“foreach”循环中。

<?php
$path = "./images/bettydew/";
$file_array = array ();
readThisDir ( $path, &$file_array );

echo '<ul class="gallery">';
foreach ( $file_array as $file )
{
  if (strstr($file, "png")||strstr($file, "jpg")||strstr($file, "bmp")||strstr($file, "gif"))
  {
    echo '<li><a href="javascript:void(0);"><img src="'.$file.'" alt="'.$file.'"/></a></li>';
  }
}
echo '</ul>';

  function readThisDir ( $path, $arr )
  {
    if ($handle = opendir($path)) 
    {
        while (false !== ($file = readdir($handle))) 
        {
            if ($file != "." && $file != "..") 
            {
              if (is_dir ( $path."/".$file ))
              {
                readThisDir ($path."/".$file, &$arr);
              } else {
                $arr[] = $path."/".$file;
              }  
            }
        }
        closedir($handle);
    }
  }
?>

将foreach循环替换为：

foreach ( $file_array as $file )
{
  if (strstr($file, "png")||strstr($file, "jpg")||strstr($file, "bmp")||strstr($file, "gif"))
  {
   list($width, $height) = getimagesize($file);
   $info = exif_read_data($file);           
   echo '<li><a href="javascript:void(0);"><img src="'.$file.'" width="'.$width.'" height="'.$height.'" alt="'.$file.'"/></a>'.$info['Title'].'</li>';
  }
}

this code is my answer to Steve's other SO answer @Steve - 请更加努力。
