一、推荐方法 CURL获取
<?php
$c = curl_init();
$url = 'www.liqingbo.cn';
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($c);
curl_close($c);
$pos = strpos($data,'utf-8');
if($pos===false){
$data = iconv("gbk","utf-8",$data);
}
preg_match("/<title>(.*)<\/title>/i",$data, $title);
echo $title[1];
?>二、使用file()函数
<?php
$lines_array = file('https://www.liqingbo.cn/');
$lines_string = implode('', $lines_array);
$pos = strpos($lines_string,'utf-8');
if($pos===false){
$lines_string = iconv("gbk","utf-8",$lines_string);
}
eregi("<title>(.*)</title>", $lines_string, $title);
echo $title[1];
?>三、使用file_get_contents
<?php
$content = file_get_contents("https://www.liqingbo.cn/");
$pos = strpos($content,'utf-8');
if($pos===false){
$content = iconv("gbk","utf-8",$content);
}
$postb = strpos($content,'<title>')+7;
$poste = strpos($content,'</title>');
$length = $poste-$postb;
echo substr($content,$postb,$length);
?>
