What happens when creating an array in PHP with non-sequential indexes?

When creating an array in PHP with non-sequential indexes, PHP will automatically convert the array to an associative array. This means that the keys will not be numeric indices but rather the keys you provide. To solve this issue and maintain non-sequential indexes, you can explicitly define the keys for each element in the array.

// Creating an array with non-sequential indexes
$array = array(0 => 'apple', 2 => 'banana', 4 => 'orange');

// Explicitly defining keys for each element
$array = array(0 => 'apple', 2 => 'banana', 4 => 'orange');
