I want to invert my array, can I do this?

The answer is yes, but it depends what you mean by invert. On clarification you wanted to amend the array so that the values and keys switched over, and this is done through using the function array_flip, like this:


<?php



$values = array("Fred","Bob","George");

print_r($values);



$values = array_flip($values);

print_r($values);

?>

Which returns:

Array
(
[0] => Fred
[1] => Bob
[2] => George
)
Array
(
[Fred] => 0
[Bob] => 1
[George] => 2
)
