This article describes the example of php using regular expressions to remember data to read xml. . Share it with everyone for your reference. The specific analysis is as follows:

The xml source file is as follows:

<&#63;xml version="1.0 encoding="UTF-8"&#63;>
<humans>
<zhangying>
<name>张映</name>
<sex>男</sex>

The php file is as follows:

<&#63;php
 $xml = "";
 $f = fopen('person.xml', 'r');
 while($data = fread($f,4096)){
  $xml .= $data;
 }
 fclose( $f );
// 上面读取数据
 preg_match_all("/\<humans\>(.*&#63;)\<\/humans\>/s",$xml,$humans); 
//匹配最外层标签里面的内容
 foreach( $humans[1] as $k=>$human )
 {
  preg_match_all("/\<name\>(.*&#63;)\<\/name\>/",$human,$name);
//匹配出名字
  preg_match_all("/\<sex\>(.*&#63;)\<\/sex\>/",$human,$sex);
//匹配出性别
  preg_match_all("/\<old\>(.*&#63;)\<\/old\>/",$human,$old);

foreach($name[1] as $key=>$val){
 echo $val." - ".$sex[$key][1]." - ".$old[$key][1]."<br>" ;
}
