What is the default index for the first element in a PHP array, and how can it be adjusted?

By default, the index for the first element in a PHP array is 0. However, you can adjust the index to start from any desired value by using the array_combine() function in PHP. This function allows you to merge two arrays, where one array contains keys and the other contains values. By specifying the desired starting index as keys in one array and the values in the other array, you can effectively set the index for the first element in the resulting array. 

// Adjusting the index for the first element in a PHP array
$keys = range(1, 5); // Define keys starting from 1
$values = ['apple', 'banana', 'cherry', 'date', 'elderberry']; // Define values for the array
$adjustedArray = array_combine($keys, $values); // Combine keys and values to create the adjusted array

print_r($adjustedArray); // Output the adjusted array
