PHP Spintax return array with all possibilities -

i have string: {hello|howdy|hola} you, {mr.|mrs.|ms.} {smith|williams|austin}!

i wonder if can me out function return array possibilities ? or @ least provide logic on how them , php functions use ?

thank you

nested foreach loops.

foreach($greetings greeting)     foreach($titles title)         foreach($names $name)             echo $greeting,' you, ',$title,' ',$name; 

you can adjust order appear sorting arrays beforehand , changing order on first 3 lines

update

this came using recursive function

it assumes have data in using regular expressions , explode should pretty trivial to:

$data = array(     array("hello","howdy","hola"),     array(" you, "),     array("mr.", "mrs.", "ms."),     array(" "),     array("smith","williams","austin"),     array("!") ); 

now here function

function permute(&$arr, &$res, $cur = "", $n = 0){      if ($n == count($arr)){         // past end of array... push results         $res[] = $cur;     } else {                     //permute 1 level down array         foreach($arr[$n] $term){             permute($arr, $res, $cur.$term, $n+1);         }     } } 

here example invocation:

$ret = array(); permute($data, $ret); print_r($ret); 

which yields output

    array (     [0] => hello you, mr. smith!     [1] => hello you, mr. williams!     [2] => hello you, mr. austin!     [3] => hello you, mrs. smith!     [4] => hello you, mrs. williams!     [5] => hello you, mrs. austin!     [6] => hello you, ms. smith!     [7] => hello you, ms. williams!     [8] => hello you, ms. austin!     [9] => howdy you, mr. smith!     [10] => howdy you, mr. williams!     [11] => howdy you, mr. austin!     [12] => howdy you, mrs. smith!     [13] => howdy you, mrs. williams!     [14] => howdy you, mrs. austin!     [15] => howdy you, ms. smith!     [16] => howdy you, ms. williams!     [17] => howdy you, ms. austin!     [18] => hola you, mr. smith!     [19] => hola you, mr. williams!     [20] => hola you, mr. austin!     [21] => hola you, mrs. smith!     [22] => hola you, mrs. williams!     [23] => hola you, mrs. austin!     [24] => hola you, ms. smith!     [25] => hola you, ms. williams!     [26] => hola you, ms. austin! )
