PHP读取网页文件内容的实现代码(fopen,curl等)

　　1.fopen实现代码:
复制代码 代码如下:
<?php
$handle = fopen (
$contents = ;
while (!feof($handle)) {
$contents .= fread($handle, 8192);
}
fclose($handle);
?>

复制代码 代码如下:
<?php
// 对 PHP 5 及更高版本
$handle = fopen(
$contents = stream_get_contents($handle);
fclose($handle);
?>

2.curl实现代码:
复制代码 代码如下:
<?php
function _url($Date){
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $Date);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_USERAGENT, Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1));
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$contents = curl_exec($ch);
curl_close($ch);
return $contents;
}
$pageURL=
$contents=_url($pageURL);
?>

编码转换函数
复制代码 代码如下:
$html = file_get_contents(
$html = iconv( Big5, UTF-8//IGNORE , $html); //转化编码方式为UTF8
print $html;
$htm = file(
$h = ;
foreach($htm as $value)
{
$h.= iconv( GB2312, utf-8//IGNORE , $value);
}
print_r($h);

另一种打开网页的方法
复制代码 代码如下:
<?php
$opts = array(
http=>array(
method=>GET,
header=>Accept-language: en\r\n .
Cookie: foo=bar\r\n
)
);
$context = stream_context_create($opts);
/* Sends an http request to
with additional headers shown above */
$fp = fopen(
fpassthru($fp);
fclose($fp);
?>
