How can I Reset Array Indexes in PHP?

Reindexing PHP Arrays: Array Deindex and Index Reset

In PHP, reindexing an array means resetting its indexes to form a continuous sequence. This can be useful when you have removed some elements from an array and the indexes are no longer in order.

To reindex an array, you can use the array_values() function. This function returns a new array with its keys renumbered to start from zero. For example, if you have an array like the one provided:

$myArray = [
    0 => "a-1",
    1 => "a-7",
    3 => "a-8",
    4 => "a-3",
];

You can use array_values() to reindex the array:

<code class="php">$myArray = array_values($myArray);</code>

This will reset the indexes so that the array appears as follows:

[
    0 => "a-1",
    1 => "a-7",
    2 => "a-8",
    3 => "a-3",
]

The array_values() function is a quick and efficient way to reindex an array in PHP.
