Use PHP to read the RSS feed code

In addition, the rss reading function is slightly transformed on the basis of this program.
If an array string is output and the encoding problem is solved.

Php source code and code are described as follows:

<? Php
// RSS source address list Array
$ Rssfeed = array ("http://www.jb51.net/feed ",
"Http://rss.sina.com.cn/news/allnews/sports.xml ",
"Http://ent.163.com/special/00031K7Q/rss_toutiao.xml ",
Http://tech.163.com/special/00091JPQ/techimportant.xml ");

// Set the encoding to UTF-8
Header ('content-Type: text/html; charset = UTF-8 ');

For ($ I = 0; $ I <sizeof ($ rssfeed); $ I ++) {// start of Decomposition
$ Buff = "";
$ Rss_str = "";
// Open the rss address and read it. If reading fails, stop
$ Fp = fopen ($ rssfeed [$ I], "r") or die ("can not open $ rssfeed ");
While (! Feof ($ fp )){
$ Buff. = fgets ($ fp, 4096 );
}
// Close the file
Fclose ($ fp );

// Create an XML Parser
$ Parser = xml_parser_create ();
// Xml_parser_set_option -- set options for specified XML Parsing
Xml_parser_set_option ($ parser, XML_OPTION_SKIP_WHITE, 1 );
// Xml_parse_pai_struct -- Parse XML data to the array $ values
Xml_parse_into_struct ($ parser, $ buff, $ values, $ idx );
// Xml_parser_free -- release the specified XML Parser
Xml_parser_free ($ parser );

Foreach ($ values as $ val ){
$ Tag = $ val ["tag"];
$ Type = $ val ["type"];
$ Value = $ val ["value"];
// Convert tags to lowercase
$ Tag = strtolower ($ tag );

If ($ tag = "item" & $ type = "open "){
$ Is_item = 1;
} Else if ($ tag = "item" & $ type = "close "){
// Construct the output string
$ Rss_str. = "<a href = '". $ link. "'target = _ blank>". $ title. "</a> <br/> ";
$ Is_item = 0;
}
// Read only the content in the item label
If ($ is_item = 1 ){
If ($ tag = "title") {$ title = $ value ;}
If ($ tag = "link") {$ link = $ value ;}
}
}
// Output result
Echo $ rss_str. "<br/> ";
}
?>
