PHP 操作xml编程之xml的crud操作
本文章来给大家介绍一个PHP 操作xml编程之xml的crud操作,有需要了解的同学可参考.
html代码页面,代码如下:
< html > < head > < meta http-equiv = "Content-type" content = "text/html;charset=utf-8" > </ head > < body > < form action = "wordProcess.php" method = "post" > < input type = "text" name = "enword" > < input type = "hidden" name = "type" value = "query" > < input type = "submit" value = "查询" > </ form > < span > 添加单词 </ span > < form action = "wordProcess.php" method = "post" > 英文: < input type = "text" name = "enword" > < br > 中文: < input type = "text" name = "zhword" > < br > <!-- < input type = "hidden" name = "type" value = "insert" > < input type = "hidden" name = "type" value = "update" > -- > < input type = "submit" name = "type" value = "添加" > < input type = "submit" name = "type" value = "修改" > </ form > < form action = "wordProcess.php" method = "post" > < input type = "text" name = "word" > < input type = "hidden" name = "type" value = "delete" > < input type = "submit" value = "删除" > </ form > </ body > </ html >wordpress.php文件,代码如下:
<?php //接收类型 看看用户做什么(查询、添加....) $type = $_REQUEST [ 'type' ]; //echo $type; //exit(); //创建xml文档对象 $doc = new DOMDocument(); $doc ->load( "words.xml" ); //进行判断 if ( $type == "query" ){ //获取用户输入的值 $enword = $_REQUEST [ 'enword' ]; //判断是否进入查询 $isEnter =false; //获取所有单词节点 $words = $doc ->getElementsByTagName( "word" ); //遍历单词节点 for ( $i =0; $i < $words ->length; $i ++){ $word_node = $words ->item( $i ); //获取不同的语种 $en_word =getNodeVal( $word_node , "en" ); $zh_word =getNodeVal( $word_node , "zh" ); //查询 if ( $enword == $en_word ){ $isEnter =true; echo $enword .
