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; } ?>
希望本文所述对大家的php程序设计有所帮助。
