在做一个ios端接口,对方传来多个json字符串,我应该如何将json数据与数据库数据做匹配?
在做一个ios端接口,对方传来多个json字符串,我应该如何将json数据与数据库数据做匹配?

我的想法是先根据ios传来的json数组来判断有多少个json字符串,然后进行循环匹配。不知方法是否正确。

如何判断json数组中有多少json字符串?
------解决思路----------------------
如果传入数据的键名都是一样的,则

$s = '[{"answer":"123"},{"answer":"222"},{"answer":"231"}]';<br />$d = json_decode($s, true);<br />$t = join(',', array_map('current', $d));<br />$k = key(current($d));<br /><br />$sql = "select * from tbl_name where $k in ($t)";<br />
Copy after login
select * from tbl_name where answer in (123,222,231)

------解决思路----------------------
<br />$data = '[{"answer":"123"},{"answer":"222"},{"answer":"231"}]';<br />$data = json_decode($data, true);<br /><br />$answers = array();<br /><br />foreach($data as $val){<br />    array_push($answers, $val['answer']);<br />}<br /><br />$sqlstr = "select * from table where answer in('".implode("','", $answers)."')";<br />#mysql_query($sqlstr) or die(mysql_error());<br />echo $sqlstr; // select * from table where answer in('123','222','231')<br />
Copy after login
