Reset PHP Array Index

Question

I have a PHP array that looks like this:

[3] => Hello
[7] => Moo
[45] => America

What PHP function makes this?

[0]         


        

Answer 1

Use array_keys() function get keys of an array and array_values() function to get values of an array.

You want to get values of an array:

$array = array( 3 => "Hello", 7 => "Moo", 45 => "America" );

$arrayValues = array_values($array);// returns all values with indexes
echo '
';
print_r($arrayValues);
echo '
';

Output:

Array
(
    [0] => Hello
    [1] => Moo
    [2] => America
)

You want to get keys of an array:

$arrayKeys = array_keys($array);// returns all keys with indexes
    echo '
';
    print_r($arrayKeys);
    echo '
';

Output:

Array
(
    [0] => 3
    [1] => 7
    [2] => 45
)
