note 49095 added to function.preg-replace

Strip all whitespace around <TAGS>. This is useful for those who want to reduce the size of their web pages by eliminating all unnecessary whitespace (\r\n\t, etc...). This code only removes the whitespace directly around a <TAG>, not the whitespace within a tag or within the string output of a tag. For example: <? ob_start(); $str = " This is some text "; ?> <html> <head> <title>My Fantastic Website! </title> </head> <body> <?=$str?> </body> </html> <? $output = preg_replace("/(\s+)?(\<.+\>)(\s+)?/", "$2", ob_get_contents()); ob_end_clean(); echo $output; ?> The output will be (instead of formatted HTML, one nice long line of HTML, minus all unnecessary whitespace characters): <html><head><title>My Fantastic Website!</title></head><body>This is some text</body></html> Although a little-bit of overhead (and I do mean *little* to non-existent) is incurred, the BYTE savings can be extremely valuable; unnecessary code isn't transmitted over the line, your code becomes tight and clean (albeit, not desirably readable to anyone viewing your source), and pages download quicker, so on... Use wisely.
