To reset it (thanks @hopeseekr):

<pre><code> reset($yourArray);

@David Murdoch added: 
<code>$myLastElement = end(array_values($yourArray));// and now you don't need to call reset().</code>

Short and sweet.

I came up with solution to remove error message and preserve one-liner form and efficient performance:

<pre><code>$lastEl = array_values(array_slice($array, -1))[0];
</code></pre>

-- previous solution

<pre><code>$lastEl = array_pop((array_slice($array, -1)));
</code></pre>

Note: The extra parentheses are needed to avoid a <code>PHP Strict standards: Only variables should be passed by reference</code>.

What's wrong with <code>array_slice($array, -1)</code>? (See Manual: <a href="http://us1.php.net/array_slice">http://us1.php.net/array_slice</a>)

<code>array_slice()</code> returns an array. Probably not what you are looking for. You want the element.

One way to avoid pass-by-reference errors (eg. "end(array_values($foo))") is to use call_user_func or call_user_func_array:

<pre><code>// PHP Fatal error: Only variables can be passed by reference
// No output (500 server error)
var_dump(end(array(1, 2, 3)));

// No errors, but modifies the array's internal pointer

var_dump(call_user_func('end', array(1, 2, 3)));

// PHP Strict standards: Only variables should be passed by reference
// Outputs "int(3)"
var_dump(end(array_values(array(1, 2, 3))));

// No errors, doesn't change the array

If you don't care about modifying the internal pointer (the following lines support both indexed and associative arrays):
<pre><code>// false if empty array
$last = end($array);

// null if empty array
$last = !empty($array) ? end($array) : null;
</code></pre>
 If you want an utility function that doesn't modify the internal pointer (because the array is passed by value to the function, so the function operates on a copy of it):
<pre><code>function array_last($array) {
 if (empty($array)) {
 return null;
 }
 return end($array);
}
</code></pre>
 Though, PHP produces copies &quot;on-the-fly&quot;, i.e. only when actually needed. As the <code>end()</code> function modifies the array, internally a copy of the whole array (minus one item) is generated.
 Therefore, I would recommend the following alternative that is actually faster, as internally it doesn't copy the array, it just makes a slice:
<pre><code>function array_last($array) {
 if (empty($array)) {
 return null;
 }
 foreach (array_slice($array, -1) as $value) {
 return $value;
 }
}
</code></pre>
Additionally, the &quot;foreach / return&quot; is a tweak for efficiently getting the first (and here single) item.
 Finally, the fastest alternative but for indexed arrays (and without gaps) only:
<pre><code>$last = !empty($array) ? $array[count($array)-1] : null;
</code></pre>

I need this quite often to deal with stacks, and i always find myself baffled that there's no native function that does it without manipulating the array or its internal pointer in some form.

So i usually carry around a util function that's also safe to use on associative arrays.

<pre><code>function array_last($array) {
 if (count($array) &lt; 1)
 return null;

 $keys = array_keys($array);
 return $array[$keys[sizeof($keys) - 1]];

Since the array returned by array_values is fleeting, no-one cares if it's pointer is reset.

Simply: <code>$last_element = end((array_values($array)))</code>

Doesn't reset the array and doesn't gives STRICT warnings. 

PS. Since the most voted answer still hasn't the double parenthesis, I submitted this answer.

blocks|key|1148127|text|现在，我更喜欢一直使用这个助手，就像在php.net/end+answer上建议的那样。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1148128|<?php

Nowadays, I'd prefer always having this helper, as suggested at an <a href="http://php.net/manual/pt_BR/function.end.php#107733" rel="nofollow noreferrer">php.net/end answer</a>.

<pre><code>&lt;?php
function endc($array) {
 return end($array);
}

$items = array('one','two','three');
$lastItem = endc($items); // three
$current = current($items); // one
?&gt;
</code></pre>

This will always keeps the pointer as it is and we will never have to worry about parenthesis, strict standards or whatever.

blocks|key|933556|text|使用end()函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|933557|$array+=+[1,2,3,4,5];

Use the end() function.

<pre><code>$array = [1,2,3,4,5];
$last = end($array); // 5

What if you want to get the last element of array inside of the loop of it's array?

The code below will result into an infinite loop:

<pre><code>foreach ($array as $item) {
 $last_element = end($array);
 reset($array);
 if ($last_element == $item) {
 // something useful here
 }
}
</code></pre>

The solution is obviously simple for non associative arrays:

<pre><code>$last_element = $array[sizeof ($array) - 1];
foreach ($array as $key =&gt; $item) {
 if ($last_element == $item) {
 // something useful here
 }
}
</code></pre>

my simple solution, pretty and easy to understand.

<pre><code>array_reverse($array)[0];

blocks|key|933890|text|array_values(array_reverse($array))适用于所有这些情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|933891|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

array_values(array_reverse($array))[0] works in all those situations.

blocks|key|932572|text|在几乎所有使用数组的语言中，使用AA.size-1是不会出错的。我想不出有哪种语言可以使用基于1的数组(而不是基于0的数组)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|932573|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In almost every language with arrays you can't really go wrong with A[A.size-1]. I can't think of an example of a language with 1 based arrays (as opposed to zero based).

Ok,

I know all about <a href="http://www.php.net/array_pop" rel="noreferrer"><code>array_pop()</code></a>, but that deletes the last element. What's the best way to get the last element of an array without deleting it?

EDIT: Here's a bonus:

<pre><code>$array = array('a' =&gt; 'a', 'b' =&gt; 'b', 'c' =&gt; 'c');
</code></pre>

or even

<pre><code>$array = array('a', 'b', 'c', 'd');
unset($array[2]);
echo $array[sizeof($array) - 1]; // Output: PHP Notice: Undefined offset: 2 in - on line 4
</code></pre>

What's the best way to get the last element of an array without deleting it?

好的,我知道关于的所有内容，但这会删除最后一个元素。获取数组的最后一个元素而不删除它的最好方法是什么？编辑:这是一个额外的奖励：$array = array('a' => 'a', 'b' => 'b', 'c' => 'c');甚至是$array = array('a', 'b', 'c', 'd');unset($array[2]);echo $array[sizeof($array) - 1
