如何在PHP中找到关联数组中第一个元素的值?
问题描述:
I have an array like this:
$array = array(
'fruit1' => 'apple',
'fruit2' => 'orange',
'fruit3' => 'grape',
);
Is there a function that'll grab 'apple'
(the first key) from that array? Or do I have no choice but to do this?
function firstkey($array)
{
for($array as $first)
{
return $first;
}
}
我有一个这样的数组: p>
$ array = 数组(
'fruit1'=>'apple',
'fruit2'=>'orange',
'fruit3'=>'grape',
);
code> pre>
是否有一个函数可以从该数组中获取'apple' code>(第一个键)? 或者我别无选择只能这样做? p>
function firstkey($ array)
{
for($ array as $ first)
{
return $ first;
}
}
code> pre>
div>
