<?php
$str = '<a id="btlist10" st="1" ditem="true" class="item multi-lines with-avatar" ftios="1" ck="TlRZNFlUSTRNakk9" 
ft="1" data="我想匹配的属性值" ix="10" analytical="false" s1="我想匹配的属性值2" 
jxd1="0781C99068C8FEBF" jxd2="69A2D6435ABEAF87817A812290560AB3" onclick="openmenu($(this))">';
$fun = function($str,$key){
    $str=preg_replace("/[\s\S]*\s".$key."[=\"\']+([^\"\']*)[\"\'][\s\S]*/","$1",$str);
    return $str;
};
$data = $fun($str, "data");
echo $data;

echo "\n";

$s1 = $fun($str, "s1");
echo $s1;

echo "\n";

$other = $fun($str, "ck");
echo $other;

echo "\n";

$other = $fun($str, "onclick");
echo $other;

?>

追问

如果我想取出多个属性值呢 能不能返回数组的 使用preg_match
