Hello Guys, I tying to figure out how to get the value of the key "user" in this case it's "bob" This is my array Array( [timeStamp] =>2020-01-2016:25:23.000443[referenceCode] => [data] =>Array( [0] =>Array( [id] =>554343543535435[clientId] =>333222[clientOid] => tysos...
(2) => Array ( (uid) => '40489', (name) => 'Michael', (pic_square) => 'urlof40489' ) ); $key = array_search(40489, array_column($userdb, 'uid')); 并且赢得了 800+ 的赞赏,到这里可能你会觉得 通过这个方式取到 index 然后用 index 取出来就行了。
//返回的数组格式是array(`id`=>array(`id`=>value,`nickname`=>value,`email`=>value))是一个二维数组,key还是id字段的值,但value是整行的array数组,类似于select()方法的结果遍历将id的值设为数组key 3、find()和order()组合使用,达到limit(1)的效果,结果得到一维数组 ...
