calling function inside preg_replace thats inside a function - php

Question

I have some code with the a structure similar to this
function bbcode($Text)
{ //$Text = preg_replace("/\[video\](.+?)\[\/video\]/",embed_video($1), $Text);
return $Text;}
function embed_video($url){
if (preg_match("/http:\/\/www.youtube.com\/watch\?v=([0-9a-zA-Z-_]*)(.*)/i", $url, $matches)) {
return '<object width="425" height="350">'.
'<param name="movie" value="http://www.youtube.com/v/'.$matches[1].'" />'.
'<param name="wmode" value="transparent" />'.
'<embed src="http://www.youtube.com/v/'.$matches[1].'&autoplay="0" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350" />'.
'</object>';
}
return $url;
}
$lolcakes = "[video]http://youtube.com/id/xxxxxxpron[/video]";
$lolcakesconverted = bbcode($lolcakes);
The problem is it spits an error back at me.
Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE or '$'
Have any ideas on how i can call embed_video inside of the preg_replace of the bbcode function?
Thanks!

Answer 1

try preg_replace_callback
return preg_replace_callback("/\[video\](.+?)\[\/video\]/", 'embed_video', $Text);
function embed_video($matches)
{
return $matches[1] . 'foo';
}

Answer 2

You can use the "e" modifier on preg_replace() (see Pattern Modifiers)
return preg_replace("/\[video\](.+?)\[\/video\]/e", "embed_video('$1')", $Text);
which tells preg_replace() to treat the second parameter as PHP code.
