array_flip

Description

array_flip() returns an array in flip order, i.e. keys from trans become values and trans's values become keys. Note that array_flip() works only with string and integer values, and it will display an alert if it detects invalid key or value (array, double, object, boolean).

If a value has several occurences, the latest key will be used as its values, and all others will be lost.

array_flip() returns FALSE if it fails.

Example 1. array_flip() example $trans = array_flip ($trans); $original = strtr ($str, $trans);

Example 2. array_flip() example : collision $trans = array ("a" => 1, "b" => 1, "c" => 2); $trans = array_flip ($trans); // now $trans is : array(1 => "b", 2 => "c");
