[SOLVED] eregi_replace not working ,convert to preg_replace

[DeanWhitehouse]

<?php 
$oldstring = "[url=bob.php]bob[/url]";

$oldstring = eregi_replace("\[url=([^\[]+)\]([^\[]+)\][/url\]","<a href=\"\\1\" target=\"_blank\">\\2</a>", $oldstring);
echo $oldstring;
?>

 

this code is not doing anything, i don't know why it doesnt work, when i echo it it just says bob, anyone any ideas or can someone convert to preg_replace if need be?

<pre>
<?php 
$oldstring = '[url=bob.php]bob[/url]';
echo $oldstring = preg_replace(
	'%\[url=([^\]]+)\]([^\[]+)\[/url\]%',
	'<a href="$1" target="_blank">$2</a>',
	$oldstring
);
?>
</pre>
