Throw away whole array but the first item - php

Question

Assume I have the following array:
$array(
'32' => array('name' => 'paul', 'age' => 43),
'17' => array('name' => 'eric', 'age' => 19),
'99' => array('name' => 'dave', 'age' => 65)
)
I am only interested in the first $array item:
$array2 = array('key'=> 32, 'name' => 'paul', 'age' => 43)
What is the most efficient way to accomplish this? In other words, can I throw out all other items of $array with one command?

Answer 1

Use array_shift().
array_shift() shifts the first value of the array off and returns it,
shortening the array by one element and moving everything down. All
numerical array keys will be modified to start counting from zero
while literal keys won't be touched.
$array2 = array_shift($array);
This means that $array2 now holds the first element, while $array holds the rest of the elements.

Answer 2

try this
$array2 = array_shift($array);

Answer 3

$newArr = reset($array);
I think there is no problem with that.

Answer 4

There are 2 options, really. Either you can just select the first item in the array
$array2 = $array[0];
Or you could use array_slice as
$array2 = array_slice($array, 0, 1);

Answer 5

Array_shift is probably the best way. But just for fun here is another way.
$first_element = end(array_reverse($array));

Answer 6

$k = array_merge(array('key' => key($array)), array_shift($array));
Returns in the specified format.
key gets you the first key, array_shift gets you the first value, and merge using array_merge

Answer 7

resetting an array also returns the first element (end() returns the last):
$first = reset( $array );
http://www.php.net/manual/en/function.reset.php
But to generate the exact result you want, you could write something like this
foreach( $array as $k => $first ){ // get first sub-array and its key
$first['key'] = $k; // add the key
break; // we don't care about the other elements, goodbye
}
Futuregeek's method fixed:
$first =
// returns first element, and sets it as the current element for key()
reset( $array )
// instead of array_merge, (sometimes) you can use the + operator
+
// key() will return the appropriate key after reset()
array('key' => key( $array ));

Answer 8

Try It :
$arr = array(
'32' => array('name' => 'paul', 'age' => 43),
'17' => array('name' => 'eric', 'age' => 19),
'99' => array('name' => 'dave', 'age' => 65)
);
foreach($arr as $key => $value)
{
$result[$key] = $value;
break;
}
print_r($result);
##-------Secount Way If you don't want Key 32--------------------------
$arr = array(
'32' => array('name' => 'paul', 'age' => 43),
'17' => array('name' => 'eric', 'age' => 19),
'99' => array('name' => 'dave', 'age' => 65)
);
$arr = array_reverse($arr);
print_r(end($arr));
#------ Third Way If you don't want Key 32 -------------
echo "<br>=======<br>";
$arr = array(
'32' => array('name' => 'paul', 'age' => 43),
'17' => array('name' => 'eric', 'age' => 19),
'99' => array('name' => 'dave', 'age' => 65)
);
$array2 = array_shift($arr);
print_r($array2);
