note 97904 added to function.str-replace

If you need to replace a string in another, but only once but still in all possible combinations (f.e. to replace "a" with "x" in "aba" to get array("xba", "abx")) you can use this function: <?php function getSingleReplaceCombinations($replace, $with, $inHaystack) { $splits = explode($replace, $inHaystack); $result = array(); for ($i = 1, $ix = count($splits); $i < $ix; ++$i) { $previous = array_slice($splits, 0, $i); $next = array_slice($splits, $i); $combine = array_pop($previous) . $with . array_shift($next); $result[] = implode($replace, array_merge($previous, array($combine), $next)); } return $result; } var_dump(getSingleReplaceCombinations("a", "x", "aba")); // result as mentioned above ?> It may not be the best in performance, but it works. ---- Server IP: 85.214.154.209 Probable Submitter: 78.42.25.223 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/97904 Del: integrated -- https://master.php.net/note/delete/97904/integrated Del: useless -- https://master.php.net/note/delete/97904/useless Del: bad code -- https://master.php.net/note/delete/97904/bad+code Del: spam -- https://master.php.net/note/delete/97904/spam Del: non-english -- https://master.php.net/note/delete/97904/non-english Del: in docs -- https://master.php.net/note/delete/97904/in+docs Del: other reasons-- https://master.php.net/note/delete/97904 Reject -- https://master.php.net/note/reject/97904 Search -- https://master.php.net/manage/user-notes.php
