note 57036 added to language.operators.bitwise

I wanted to print a binary representation of an integer here it is <?php function binString($var, $safety = 0) { return ($var & 1) . ($var != 0 && $safety < 31 ? binString($var >> 1, $safety+1) : ""); } print binString(5); // would print 101 print binString(15); // would print 1111 ?> Explanation: the first expression after the return statement will evaluate to 1 or 0 according to the least significant bit. then we have our stop condition if there is still non zero bits left or if we are at the 32nd bit otherwise we call recursively on to the n-1 bits (by shifting out the least significant bit). ---- Manual Page -- http://www.php.net/manual/en/language.operators.bitwise.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57036 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57036&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57036&report=yes Search -- http://master.php.net/manage/user-notes.php
