Re: Need regular match help - possibly

Thinking about it, this would probably be even better: $string = preg_replace("/(\n|<br>){3,}/i", "\\1\\1\\1", $string); This: $string = "This is a \n\n\n\n\n\n\n\n\n\n\ntest\nTesting\nTesting\n\n123<br><br><br><br><br><br>< br><br><br><br><br>Some more br>testing<br><br><br><br><br><br><br><br><br>And a little more<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br>Even more."; Then outputs as this: This is a <br /> <br /> <br /> test<br /> Testing<br /> Testing<br /> <br /> 123<br><br><br>Some more testing<br><br><br>And a little more<br><br><br>Even more. when echo'd with nl2br() As a side note, does anyone know what's with the <br> tag changing to <br />?
