我有如下数组:
function example() {
/* some stuff here that pushes items with
dynamically created key strings into an array */
return array( // now lets pretend it returns the created array
'firstStringName' => $whatEver,
'secondStringName' => $somethingElse
);
}
$arr = example();
// now I know that $arr contains $arr['firstStringName'];
我需要找出的索引,$arr['firstStringName']
以便能够遍历array_keys($arr)
并'firstStringName'
通过其索引返回键字符串。我怎样才能做到这一点?
您能否详细说明您要实现的目标?
