To modify an associative array in PHP so that its values become keys, you can use the array_flip() function. This function takes an array as input and returns a new array where the keys and values are flipped. Here is an example:
// original associative array
$fruits = array(
'apple' => 'red',
'banana' => 'yellow',
'orange' => 'orange'
);
// flip array using array_flip()
$colors = array_flip($fruits);
// output new associative array with values as keys
print_r($colors);
This code will output:
Array
(
[red] => apple
[yellow] => banana
[orange] => orange
)
As you can see, the keys and values have been flipped, so the values are now the keys in the new array.
