[@height] =&gt; 429
)
</code></pre>

have 5 values with indexes <code>@url, @type, @expression, @width, @height</code>. So it always will give you the count 5.

If you want to get count 1. You have to do like below

<pre><code>$temp = Array(
 array(
 [@url] =&gt; url
 [@type] =&gt; image/jpeg
 [@expression] =&gt; full
 [@width] =&gt; 644
 [@height] =&gt; 429

);
</code></pre>

Here <code>count($temp)</code> will give you output 1

Single result:

<pre><code>$new_temp[0] = $temp;

Now you get:

<pre><code>count($new_temp); // get 1

Problem is that in your first block of code you are trying to count number of elements of array which in second block is insido of another array.

blocks|key|587313|text|它正在计算数组中的元素数量。第一个是给你5，因为数组有5个元素。第二个是2，因为它是一个包含2个元素(数组)的多数组。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|587314|要使其返回一个数组，可以将数组放入数组中，如下所示：|587315|Array([0]+=>+Array())|code-block|syntax|javascript|587316|我希望这回答了你的问题。|587317|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|$]]

It is counting the amount of elements in the array. The first is giving you 5 because the array has 5 elements. The second is giving you 2 because it is a multi-array containting 2 elements (arrays).

To make it return one you can put the array inside of an array, so like this:

<pre><code>Array([0] =&gt; Array())
</code></pre>

I hope this answered your question.

I have 2 following data:

<pre><code>$temp = Array
(
 [@url] =&gt; url
 [@type] =&gt; image/jpeg
 [@expression] =&gt; full
 [@width] =&gt; 644
 [@height] =&gt; 429
)

$count_total = count($temp); // gives me 5, how can it give me total = 1?
</code></pre>

<hr>

<pre><code>Array
(
 [0] =&gt; Array
 (
 [@url] =&gt; url1
 [@type] =&gt; image/jpeg
 [@expression] =&gt; full
 [@width] =&gt; 800
 [@height] =&gt; 621
 )

 [1] =&gt; Array
 (
 [@url] =&gt; url2
 [@type] =&gt; application/x-shockwave-flash
 )

)
this is total:2 // this is correct
</code></pre>

How can I get first array count as 1?
