Say me, why a function str_repeat() really work in this situation: <?php $s = "A-B"; echo preg_replace("/\-([a-z])/iU", str_repeat("$1", 10), $s); ?> // -------------- // ACTUAL RESULT: // -------------- ABBBBBBBBBB Why? See that: <?php $s = "A-B"; echo preg_replace("/\-([a-z])/iU", strtolower(str_repeat("$1", 10)), $s); ?> // -------------- // ACTUAL RESULT: // -------------- ABBBBBBBBBB // Why that ? :) ------------------------------------------------------------------------ [2006-12-16 18:09:15] judas dot iscariote at gmail dot com Why you think this is a bug ? you are looking for preg_replace_callback ... or if you are crazy, the preg_replace "/e" modifier. not a bug, read the manual ;-) ------------------------------------------------------------------------ [2006-12-16 12:40:44] ara at lenta dot ru Tu XYu. ------------------------------------------------------------------------ [2006-12-16 12:37:46] anton dot kirsanov at gmail dot com Sorry, am mix up a 'Expected result' and 'Actual result' :) Please read this quite the contrary - 'Expected result' is a 'Actual result'. ------------------------------------------------------------------------ [2006-12-16 12:35:36] ara at lenta dot ru &#1090;&#1099; &#1093;&#1091;&#1081; ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
