Answer 1

//$a=>>>html   要改成 $a=<<<……
preg_match_all('/"url":"(.*?)","subtitle":"(.*?)"/is', $a, $out);
for($i=0,$n=count($out[1]);$i<$n;$i++)
{
echo '<a href="' . $out[1][$i] . '">' . $out[2][$i] . '</a>';
}//===================================
//如果是笔误，"title":婚庆达人",  => "title":"婚庆达人",
print_r(json_decode(str_replace(array("\n", "\r", "\t"), '', preg_replace('/.*var data=/is', '', $a))));
