Description
array
array_flip ( array trans)
array_flip() returns an array in flip
order, i.e. keys from trans become values and
trans's values become keys.
Note that the values of trans need to be valid
keys, i.e. they need to be either integer or
string. A warning will be emitted if a value has the wrong
type, and the key/value pair in question will not be
flipped.
If a value has several occurrences, 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);
print_r($trans); |
now $trans is :
Array
(
[1] => b
[2] => c
) |
