用PHP编程语言抓取网页的HTML内容汇总
首先，放一些比较小巧的程序，但是功能和实际效果有待完善。
①、使用php获取网页内容
http://hi.baidu.com/quqiufeng/blog/item ... e7150.html
[code]<?php
header("Content-type: text/html; charset=utf-8");
1、
$xhr = new COM("MSXML2.XMLHTTP");
$xhr->open("GET","http://localhost/xxx.php?id=2",false);
$xhr->send();
echo $xhr->responseText;
?>[/code]
2、file_get_contents实现
[code]<?php
$url="http://www.blogjava.net/pts";
echo file_get_contents( $url );
?>[/code]
3、fopen()实现
[code]<?
if ($stream = fopen('http://www.sohu.com', 'r')) {
// print all the page starting at the offset 10
echo stream_get_contents($stream, -1, 10);
fclose($stream);
}
if ($stream = fopen('http://www.sohu.net', 'r')) {
// print the first 5 bytes
echo stream_get_contents($stream, 5);
fclose($stream);
}
?>[/code]
②、使用php获取网页内容
http://www.blogjava.net/pts/archive/200 ... 99188.html
简单的做法:
[code]<?php
$url="http://www.blogjava.net/pts";
echo file_get_contents( $url );
?>[/code]
或者:
[code]<?
if ($stream = fopen('http://www.sohu.com', 'r')) {
// print all the page starting at the offset 10
echo stream_get_contents($stream, -1, 10);
fclose($stream);
}
if ($stream = fopen('http://www.sohu.net', 'r')) {
// print the first 5 bytes
echo stream_get_contents($stream, 5);
fclose($stream);
}
?>[/code]
③、PHP获取网站内容，保存为TXT文件源码

[code]<?
$my_book_url='http://book.yunxiaoge.com/files/article/html/4/4550/index.html';
ereg("http://book.yunxiaoge.com/files/article/html/[0-9]+/[0-9]+/",$my_book_url,$myBook);
$my_book_txt=$myBook[0];
$file_handle = fopen($my_book_url, "r");//读取文件
unlink("test.txt");
while (!feof($file_handle)) { //循环到文件结束
$line = fgets($file_handle); //读取一行文件
$line1=ereg("href=\"[0-9]+.html",$line,$reg); //分析文件内部书的文章页面
$handle = fopen("test.txt", 'a');
if ($line1) {
$my_book_txt_url=$reg[0]; //另外赋值,给抓取分析做准备
$my_book_txt_url=str_replace("href=\"","",$my_book_txt_url);
$my_book_txt_over_url="$my_book_txt$my_book_txt_url"; //转换为抓取地址
echo "$my_book_txt_over_url</p>"; //显示工作状态
$file_handle_txt = fopen($my_book_txt_over_url, "r"); //读取转换后的抓取地址
while (!feof($file_handle_txt)) {
$line_txt = fgets($file_handle_txt);
$line1=ereg("^ .+",$line_txt,$reg); //根据抓取内容标示抓取
$my_over_txt=$reg[0];
$my_over_txt=str_replace(" "," ",$my_over_txt); //过滤字符
$my_over_txt=str_replace("<br />","",$my_over_txt);
$my_over_txt=str_replace("<script language=\"javascript\">","",$my_over_txt);
$my_over_txt=str_replace(""","",$my_over_txt);
if ($line1) {
$handle1=fwrite($handle,"$my_over_txt\n"); //写入文件
}
}
}
}
fclose($file_handle_txt);
fclose($handle);
fclose($file_handle); //关闭文件
echo "完成</p>";
?> [/code]
