You can do foreach loops to achieve much the same thing as a typical for-loop.

<pre><code>foreach ($foods as $key =&gt; $value) {
 //For the first iteration, $key will equal 'vegetable' and $value will be the array
}
</code></pre>

try 

<pre><code>$new_array = array_values($food);

however, variable can't start with <code>.</code>. It should start with $

blocks|key|827714|text|$food[1][0]+!=+$food[1]['apple']，所以在这种情况下不能使用数字键。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|827715|entityMap^0|0|W|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

<code>$food[1][0] != $food[1]['apple']</code>, so you cannot use numeric keys in this case.

blocks|key|4610975|text|您可以在数组上使用array_keys()。结果数组可以通过for循环遍历，并为您提供关联键。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4610976|我将展示它的第一个维度：|4610977|$aTest+=+array('lol'+=>+'lolval',+'rofl'+=>+'roflval');
$aKeys+=+array_keys($aTest);
$iCnt+=+count($aKeys);

for($i+=+0;+$i+<+$iCnt;+%2B%2B$i)
{
++var_dump($aTest[$aKeys[$i]]);
}|code-block|syntax|javascript|4610978|您需要为两个维度执行此操作，但我不建议这样做。实际上，它比大多数其他解决方案更难理解，速度也更慢。|4610979|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You can use array_keys() on the array. The resulting array can be traversed via a for-loop and gives you the associative key.

I will show it to you for the first dimension:

<pre><code>$aTest = array('lol' =&gt; 'lolval', 'rofl' =&gt; 'roflval');
$aKeys = array_keys($aTest);
$iCnt = count($aKeys);

for($i = 0; $i &lt; $iCnt; ++$i)
{
 var_dump($aTest[$aKeys[$i]]);
}
</code></pre>

You would need to do this for two dimensions but I would not recommend this. It is actually more obstrusive and slower than most other solutions.

blocks|key|4611034|text|您可能想尝试使用函数array_values，但由于您正在处理多维数组，下面是一位php程序员发布的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4611035|http://www.php.net/manual/en/function.array-values.php#103905|offset|length|4611036|但是使用foreach会比使用for更容易。|4611037|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1P|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@$D|Q|E|R|1|S]]|A|$]]|$1|F|3|G|5|6|7|T|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|C]]]]

you may want to try the function array_values but since you are dealing with multidemsional arrays, here is a solution posted by a php programmer

<a href="http://www.php.net/manual/en/function.array-values.php#103905" rel="nofollow">http://www.php.net/manual/en/function.array-values.php#103905</a>

but it would be easier to use foreach instead of for.

blocks|key|4611062|text|我不认为有什么原生的东西可以走这条路。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4611063|看起来你确实是在尝试扩展数组的使用。|4611064|你应该在这个问题上进行OOP。|4611065|创建一个FoodFamilly对象和一个Food对象，如果需要，您可以在其中存储数组，并且您将能够编写用户友好的代码，并在需要时添加索引。|4611066|OOP几乎总是答案:)|4611067|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I don't think there is something native to go this route. 

And it does seem like you are trying to stretch array use a bit. 

You should go OOP on this one. 

Create a FoodFamilly object and a Food object in which you can store arrays if necessary and you'll be able to write a nice user-friendly code and add indices if needed.

OOP is almost always the answer :)

Lets say I have an multidimensional string array:

<pre><code>.food = array(
 'vegetable' =&gt; array(
 'carrot' =&gt; 'blablue', 
 'potato' =&gt; 'bluebla', 
 'cauliflower' =&gt; 'blabla'
 ), 
 'Fruit' =&gt; array(
 'apple' =&gt; 'chicken65', 
 'orange' =&gt; 'salsafood', 
 'pear' =&gt; 'lokkulakka'
 )
);
</code></pre>

is it possible to access the array by using index as numbers, instead of using the name of the key?
So for accessing chicken65 , I will type echo $food[1][0]; I don't want to use numbers as key, because its a big array and its more user-friendly if I use string as key and it will let me do for-loops on advanced level.

How do I get index of an string array on php?
