note 52620 added to function.strrev

strrev() can be very useful in cases where it makes more sense to do something from the end of a string rather than the beginning (well duh!) such as apply certain regular expressions. Here's a small function to add commas to numbers that works in such a way. <?php echo commafy("1500000.1254"); // prints 1,500,000.1254 function commafy($_) { return strrev( (string)preg_replace( '/(\d{3})(?=\d)(?!\d*\.)/', '$1,' , strrev( $_ ) ) ); } ?> I originally wrote it in Perl, does it show? ;=) ---- Manual Page -- http://www.php.net/manual/en/function.strrev.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52620 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52620&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52620&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52620&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52620&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52620&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52620&report=yes Search -- http://master.php.net/manage/user-notes.php
