Get the last key-value pair in a PHP array

Question

I have an array that is structured as follows:

[33] => Array ( [time] => 1285571561 [user] => test0 ) [34] => Array ( [time] => 1285571659 [user] => test1 ) [35] => Array ( [time] => 1285571682 [user] => test2 ) 

How can I get the last value in an array, but maintaining the index [35]?

The result I'm looking for is this:

 [35] => Array ( [time] => 1285571682 [user] => test2 ) 

Answer 1

try using

 end($array); 

Answer 2

 $last = array_slice($array, -1, 1, true); 

See http://php.net/array_slice for more details on what arguments mean.

PS Unlike other answers, this one actually does what you want. :-)

Answer 3

You can use end to push the internal pointer to the end or array_slice to get an array containing only the last element:

 $last = end($arr); $last = current(array_slice($arr, -1)); 

Answer 4

If you have an array

 $last_element = array_pop(array); 

Answer 5

Example 1:

 $arr = array("a"=>"a", "5"=>"b", "c", "key"=>"d", "lastkey"=>"e"); print_r(end($arr)); 

Conclusion = e

---

Example 2:

ARRAY without keys.

 $arr = array("a", "b", "c", "d", "e"); print_r(array_slice($arr, -1, 1, true)); // output is = array( [4] => e ) 

---

Example 3:

ARRAY with key (s)

 $arr = array("a"=>"a", "5"=>"b", "c", "key"=>"d", "lastkey"=>"e"); print_r(array_slice($arr, -1, 1, true)); // output is = array ( [lastkey] => e ) 

---

Example 4:

If your keys are an array such as: [0] [1] [2] [3] [4] ... etc. You can use this:

 $arr = array("a","b","c","d","e"); $lastindex = count($arr)-1; print_r($lastindex); 

Output = 4

---

Example 5: But if you are not sure!

 $arr = array("a"=>"a", "5"=>"b", "c", "key"=>"d", "lastkey"=>"e"); $ar_k = array_keys($arr); $lastindex = $ar_k [ count($ar_k) - 1 ]; print_r($lastindex); 

Output = lastkey

Answer 6

As Gumbo said,

 <?php $fruits = array('apple', 'banana', 'cranberry'); echo end($fruits); // cranberry ?> 

Answer 7

Another cool solution:

 $value = $arr[count($arr) - 1]; 

The above will count the number of array values, subtract 1 and then return the value.

Note. This can only be used if your array keys are numeric.

Answer 8

Since the key is needed, the decision does not work.

It:

 end($array); return array(key($array) => array_pop($array)); 

will come back exactly as an example in the question.

Answer 9

"SPL-way" :

 $splArray = SplFixedArray::fromArray($array); $last_item_with_preserved_index[$splArray->getSize()-1] = $splArray->offsetGet($splArray->getSize()-1); 

More about SplFixedArray and why in some cases (especially with massive data of large indices) it is preferable to the base array , here => Class SplFixedArray .
