file_get_contents问题
代码如下:
$text=strstr(file_get_contents(http://www.baidu.com/s?wd=百度'),'找到相关结果约');
运行后 $text 为什么没值;
------解决方案--------------------
你在浏览器地址栏输入 http://www.baidu.com/s?wd=百度
你看到了 找到相关结果约 字样了吗?
我眼神不好,没看见
------解决方案--------------------
你不说我也找不到那个 相关结果,以前相关结果都是在上面的。
你的代码少了个' 不过即使加了也是一个效果.
弄这种东西 最好的就是正则了
$html = file_get_contents('http://www.baidu.com/s?wd=百度');
$html = iconv('GBK', 'UTF-8', $html);//如果你的页面是utf-8编码需要一个转换
preg_match('/找到相关结果约([0-9,]+个)/', $html, $math);
echo $math[1];
