PHP array_values

It is an in-built function in PHP that is used to show element values of a given array in a new array. PHP array_values function creates a new array in which it stores only values of elements from a given array and by default gives the numerical keys to every single value. 

Syntax

array_values($array);

Parameters

PHP array_values function takes only one parameter from which it will store the values.

Let’s try the examples.

Example 1

<?php

$arr=array("Name"=>"Ali","Age"=>"20","Country"=>"Pakistan");

echo "<pre>";

print_r(array_values($arr));

echo "</pre>";

?>

In the above example, we declared an associative array, and then we used the array_values() function.

Output

Array
(
    [0] => Ali
    [1] => 20
    [2] => Pakistan
)

Now you can see a new array has been created and only values are showing in it.

What if we declare an index array with an array value function? See the example below.

Example 2

<?php

$arr = ['One', 'Two', 'Three', 'four', 'five'];

echo "<pre>";

print_r(array_values($arr));

echo "</pre>";

?>

Output

Array
(
    [0] => One
    [1] => Two
    [2] => Three
    [3] => four
    [4] => five
)

As you can see from the output that’s how it works with the index array, the array_values() function assign every single value a numerical key. 

Example 3 – Multi-Dimensional Array

<?php

$emp = [

  'name' => 'memon',

  'email' => '[email protected]',

  'phone' => '1234567890',

  'hobbies' => ['reading', 'Tennis'],

  'profiles' => ['facebook' => 'memonfb', 'instagram' => 'memoninst']

];

echo "<pre>";

print_r(array_values($emp));

echo "</pre>";

?>

In the above example, we declared a multidimensional array and then used the Array_values() function let’s check out the results.

Output

Array
(
    [0] => memon
    [1] => [email protected]
    [2] => 1234567890
    [3] => Array
        (
            [0] => reading
            [1] => Tennis
        )
 
    [4] => Array
        (
            [facebook] => memonfb
            [instagram] => memoninst
        )
 
)

See how the information is printed, first of all, it printed the first three values and assigns them index keys then on the no:3 index key it printed the array value, and then on no:4 another array value is printed, the Array_values() function printed the whole array values while keeping their index keys in sequential order.

Conclusion

In this tutorial, we learned about the array_values function, see the definition, and then discuss some examples.
