本文实例讲述了php将html转成wml的WAP标记语言的方法。分享给大家供大家参考。具体实现方法如下:

<?php//---------------------------------------// Html 标记WAP语言//----------------------------------------function html2wml($content){  //保留图片  preg_match_all("/<img([^>]*)>/isU", $content, $imgarr);  if(isset($imgarr[0]) && count($imgarr[0])>0 )  {   foreach($imgarr[0] as $k=>$v) $content = str_replace($v, "WAP-IMG::{$k}", $content);  }  // 过滤掉样式表和脚本  $content = preg_replace("/<style .*?<\/style>/is", "", $content);  $content = preg_replace("/<script .*?<\/script>/is", "", $content);  // 首先将各种可以引起换行的标签(如<br />、<p> 之类)替换成换行符"\n"  $content = preg_replace("/<br \s*\/?\/>/i", "\n", $content);  $content = preg_replace("/<\/?p>/i", "\n", $content);  $content = preg_replace("/<\/?td>/i", "\n", $content);  $content = preg_replace("/<\/?div>/i", "\n", $content);  $content = preg_replace("/<\/?blockquote>/i", "\n", $content);  $content = preg_replace("/<\/?li>/i", "\n", $content);  // 将" "替换为空格  $content = preg_replace("/\ \;/i", " ", $content);  $content = preg_replace("/\ /i", " ", $content);  // 过滤掉剩下的 HTML 标签  $content = strip_tags($content);  // 将 HTML 中的实体(entity)转化为它所对应的字符  $content = html_entity_decode($content, ENT_QUOTES, "GB2312");  // 过滤掉不能转化的实体(entity)  $content = preg_replace("/\&\#.*?\;/i", "", $content);  // 上面是将 HTML 网页内容转化为带换行的纯文本,下面是将这些纯文本转化为 WML。  $content = str_replace("$", "$$", $content);  $content = str_replace("\r\n", "\n", htmlspecialchars($content));  $content = explode("\n", $content);  for ($i = 0; $i < count($content); $i++)  {  $content[$i] = trim($content[$i]);  // 如果去掉全角空格为空行,则设为空行,否则不对全角空格过滤。  if (str_replace(" ", "", $content[$i]) == "") $content[$i] = "";  }  $content = str_replace("<p><br /></p>\n", "", "<p>".implode("<br /></p>\n<p>", $content)."<br /></p>\n");  //还原图片  if(isset($imgarr[0]) && count($imgarr[0])>0 )  {    foreach($imgarr[0] as $k=>$v)    {     $attstr = (preg_match("#/$#", $imgarr[1][$k])) ? "<img ".$imgarr[1][$k].">" : "<img ".$imgarr[1][$k]." />";     $content = str_replace("WAP-IMG::{$k}", $attstr, $content);    }  }  $content = preg_replace("/&[a-z]{3,10};/isU", " ", $content);  return $content;}function text2wml($content){  $content = str_replace("$", "$$", $content);  $content = str_replace("\r\n", "\n", htmlspecialchars($content));  $content = explode("\n", $content);  for ($i = 0; $i < count($content); $i++)  {  // 过滤首尾空格  $content[$i] = trim($content[$i]);  // 如果去掉全角空格为空行,则设为空行,否则不对全角空格过滤。  if (str_replace(" ", "", $content[$i]) == "") $content[$i] = "";  }  //合并各行,转化为 WML,并过滤掉空行  $content = str_replace("<p><br /></p>\n", "", "<p>".implode("<br /></p>\n<p>", $content)."<br /></p>\n");  return $content;}?>
