Shuffled strings (PHP version)

Find out the out-of-order strings in some strings, such as "abc", "cba" is a set of out-of-order strings

Example

Input: (hello,lloeh,helll,olelh,code,abc, cba,dec,asd,bca,);

Output:

array ( [0] => hello [1] => lloeh [2] => olelh [3] => abc [4] => cba [5] => bca )
