Een str_replace voor spatie?

$in = str_replace("[color=#", "[color=", $in);


	$patterns = array(
	"#\[b\](.*?)\[/b\]#si",
	"#\[u\](.*?)\[/u\]#si",
	"#\[i\](.*?)\[/i\]#si",
	"#\[s\](.*?)\[/s\]#si",
	"#\[center\](.*?)\[/center\]#si",
	"#\[color=(.*?)\](.*?)\[/color\]#si",
	"#\[size=(.*?)\](.*?)\[/size\]#si",
	"#\[right\](.*?)\[/right\]#si",
	"#\[qt=(.*?)\](.*?)\[/qt\]#si",
	);


	$replaces = array(
	"<b>\\1</b>",
	"<u>\\1</u>",
	"<i>\\1</i>",
	"<s>\\1</s>",
	"<center>\\1</center>",
	"<font color=\"#\\1\">\\2</font>",
	"<font size=\"\\1\">\\2</font>",
	"<div style=\"text-align: right;\" align=\"right\">\\1</div>",
	"<table width=\"70%\" style=\"border: 1px dashed #000; max-width: 100%; margin-left: 10px; margin-top: 7px; margin-bottom:3px;\" cellspacing=\"0\">
		<tr>
			<td class=\"inhoud\" style=\"padding: 2px;\">
				<b>\\1</b> schreef:<br>

			</td>
		</tr>
	</table>"
