note 38495 added to function.base-convert

I needed a function to invert a hex value, which i used for setting font colors when they were on a colored background, that way i will get a contrasting color. Im sure there are other reasons to use this, you decide!! <?php function InvertColor($hex) { return sprintf("%06s",base_convert(($hex ^ 0xFFFFFF),10,16)); }; print '<td bgcolor="BB2222"><font color="'.InvertColor(0xBB2222).'">Blah</font></td>'; // Prints 44dddd as the font color, which is it's opposite on the color wheel ?> ---- Manual Page -- http://www.php.net/manual/en/function.base-convert.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+38495 Delete -- http://master.php.net/manage/user-notes.php?action=delete+38495&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+38495&report=yes Search -- http://master.php.net/manage/user-notes.php
