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:
<?xml version="1.0 encoding="UTF-8"?> <humans> <zhangying> <name>张映</name> <sex>男</sex> <old>28</old> </zhangying> <tank> <name>tank</name> <sex>男</sex> <old>28</old> </tank> </humans>
The php file is as follows:
<?php
$xml = "";
$f = fopen('person.xml', 'r');
while($data = fread($f,4096)){
$xml .= $data;
}
fclose( $f );
// 上面读取数据
preg_match_all("/\<humans\>(.*?)\<\/humans\>/s",$xml,$humans);
//匹配最外层标签里面的内容
foreach( $humans[1] as $k=>$human )
{
preg_match_all("/\<name\>(.*?)\<\/name\>/",$human,$name);
//匹配出名字
preg_match_all("/\<sex\>(.*?)\<\/sex\>/",$human,$sex);
//匹配出性别
preg_match_all("/\<old\>(.*?)\<\/old\>/",$human,$old);
//匹配出年龄
}
foreach($name[1] as $key=>$val){
echo $val." - ".$sex[$key][1]." - ".$old[$key][1]."<br>" ;
}
?>
I hope this article will be helpful to everyone’s PHP programming design.
