I think the best way to do it is to create a global var array. Then do whatever you want to it inside the function data by passing it as a reference. No need to return anything too.

<pre><code>$array = array("white", "black", "yellow");
echo $array[0]; //this echo white
data($array);

function data(&amp;$passArray){ //&lt;&lt;notice &amp;
 $passArray[0] = "orange"; 
}
echo $array[0]; //this now echo orange

 $array = array($a, $b, $c);

}|code-block|syntax|javascript|929054|我的功能没有问题。我在一个循环中读取数据以显示我的相关数据。我不知道为什么会有人提出上述方法。如果您希望在一个文件中存储多个数组，但没有加载所有数组，则使用上面的函数方法。否则，所有的数组都会加载到页面上，从而减慢站点的速度。我想出了这段代码，将我所有的数组存储在一个文件中，并在需要时使用单独的数组。|929055|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I was looking for an easier method than i'm using but it isn't answered in this post. However, my method works and i don't use any of the aforementioned methods:

<pre><code>function MyFunction() {
 $lookyHere = array(
 'value1' =&gt; array('valuehere'),
 'entry2' =&gt; array('valuehere')
 );
 return $lookyHere;
}
</code></pre>

I have no problems with my function. I read the data in a loop to display my associated data. I have no idea why anyone would suggest the above methods. If you are looking to store multiple arrays in one file but not have all of them loaded, then use my function method above. Otherwise, all of the arrays will load on the page, thus, slowing down your site. I came up with this code to store all of my arrays in one file and use individual arrays when needed.

Your function is:

<pre><code>function data(){

$a = "abc";
$b = "def";
$c = "ghi";

return array($a, $b, $c);
}
</code></pre>

It returns an array where position 0 is $a, position 1 is $b and position 2 is $c. You can therefore access $a by doing just this:

data()[0]

If you do $myvar = data()[0] and print $myvar, you will get "abc", which was the value assigned to $a inside the function.

I need to return multiple values from a function, therefore I have added them to an array and returned the array.
<pre><code>&lt;?
function data(){
 $a = &quot;abc&quot;;
 $b = &quot;def&quot;;
 $c = &quot;ghi&quot;;

 return array($a, $b, $c);
}
?&gt;
</code></pre>
How can I receive the values of <code>$a</code>, <code>$b</code>, <code>$c</code> by calling the above function?

How to access the elements of a function's return array?

我需要从一个函数返回多个值，因此我将它们添加到一个数组中并返回该数组。<?function data(){ $a = "abc"; $b = "def"; $c = "ghi"; return array($a, $b, $c);}?>如何通过调用上述函数获取$a、$b、$c的值？
