This article mainly introduces simplexml_load_file function usage in php, and describes in detail the methods used by simplexml_load_file to read XML files in the form of instances. It is very practical and useful.

This example describes the usage of simplexml_load_file in php. Share it with you for your reference. The usage analysis is as follows:

In php, after the simplexml_load_file () function loads the XML document into an object, we can use the objects returned by the function to perform related operations. Let's take a look at several test instances.

For example, the XML file code is as follows:

The Code is as follows:

<? Xml version = "1.0" encoding = "ISO-8859-1"?>

George
John
Reminder
Don't forget the meeting!

The PHP code is as follows:

The Code is as follows:

<? Php
If (file_exists ('test. xml '))
{
$ Xml = simplexml_load_file ('test. xml ');
Var_dump ($ xml );
}
Else
{
Exit ('error .');
}
?>

The output result is as follows:

The Code is as follows:

Object (SimpleXMLElement) #1 (4 ){
["To"] =>
String (6) "George"
["From"] =>
String (4) "John"
["Heading"] =>
String (8) "Reminder"
["Body"] =>
String (25) "Don't forget the meeting! "
}

Assume that there is an "ICBA. xml" file with the following content:

The Code is as follows:

<? Xml version = "1.0" encoding = "UTF-8"?>

Sky

Array;

The church tower stood against the sky like a finger pointing towards heaven.
The tower of the Church is like a finger pointing to the sky.


A balloon floated into ss the sky.
The balloon floated across the sky.


A bolt of lightning pointer up the sky.
(A) lightning illuminates the sky.


A bright moving object appeared in the sky at sunset.
A moving shiny object appeared in the sky.


A bright rainbow arched abve.
A bright rainbow hangs in the sky.

In PHP, we can use the following method to obtain the desired value:

The Code is as follows:

<? Php
$ Xmldata = simplexml_load_file ("ICBA. xml ");

Header ("Content-Type: text/html; charset = UTF-8 ");
Print_r ($ xmldata); // The First Part

$ Listcount = count ($ xmldata-> sent );

For ($ I = 0; $ I <$ listcount; $ I ++) {// The second part
$ Dictlist = $ xmldata-> sent [$ I];
Echo"
Example: ". $ dictlist-> orig;
Echo"
Translation: ". $ dictlist-> trans;
}
?>

"Part 1" will output:

The Code is as follows:

SimpleXMLElement Object
(
[@ Attributes] => Array
(
[Num] = & gt; 219
[Id] = & gt; 219
[Name] = & gt; 219
)

[Key] => sky
[Pos] => SimpleXMLElement Object
(
)

[Acceptation] => Array;
[Sent] => Array
(
[0] => SimpleXMLElement Object
(
[Orig] => The church tower stood against the sky like a finger pointing towards heaven.
[Trans] => the tower of the Church is like a finger pointing to the sky under the background of the sky.
)
