字符串乱码
<?php$url = 'http://luolai.tmall.com/search.htm?pageNum=1'; $lines_array = file($url); echo $lines_array; echo "<br/>"; $lines_string = implode('', $lines_array); eregi("<title>(.*)</title>", $lines_string, $head); echo "head:".$head; echo "<br/>"; print_r($head); echo "<br/>"; echo "title:".$head[1]; ?>
这个打印出来有乱码,如何才能不乱码?
回复讨论(解决方案)
试试这个: function file_get_contents_utf8($fn) {
$content = file_get_contents($fn);
return mb_convert_encoding($content, 'UTF-8',
mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}
?>
淘宝是gb2312编码,而你的是utf-8编码,因此就乱码了。
echo "title:".iconv('gbk','utf-8',$head[1]);
他的页面是 gb2312 的,而你的是 utf-8 的
所以在打印前应做编码转换
$head = iconv('gbk', 'utf-8', $head);
楼上三位的都取不出字符串,显示为空白
用iconv函数或者mb_convert_encoding函数转换整个网页file_get_contents显示不出乱码,但是用正则就是无法取出中间的中文字符串。
虽然有 Deprecated: Function eregi() is deprecated in Array 错误警告
但结果还是有的
Array
