上面那段代码,我想提取城市名称和链接,应该如果操作,请好心人帮忙,非常感谢,我对正则表达式不是很了解


回复讨论(解决方案)

preg_match_all('/]+href="?([^>"]+)"?\s*[^>]*>(.+?)/i',$data,$arr); 

把所有的span内容定义成一个字符串,然后写一个正则表达式匹配,返回一个数组,打印数组,看到结构,根据需要取值:
$str="全部中山珠海潮州东莞佛山茂名揭阳清远梅州河源广州江门惠州云浮阳江肇庆湛江汕尾汕头深圳韶关";
$reg="/\(.*?)\/mi";
preg_match_all($reg,$str,$arr);
echo "

";  <br> print_r($arr);  <br> echo "
";
?>

preg_match_all('/<a[^>]+href=["\']?([^>"\']+)["\']?\s*[^>]*>(.+?)<\/a>/i', $str, $arr, PREG_SET_ORDER);
