I am looking for a 'reasonably fast' PHP method to find all possible permutations of specific text fragments.
Note, no need for array recursion, but an array could be big.
Example:
<?php
$fragments [] = "al";
$fragments [] = "ex";
$fragments [] = "00";
$permutations = permuteTxt($fragments);
print_r($permutations);
?>
Result:
- alex00
- 00alex
- exal00
- al00ex
- 00exal
- ex00al
I would appreciate your help, and a brief explanation of your brainstorming on how you got it together.
