我試圖替換[picasa和],但以下代碼片段無法正常工作。PHP - 爲什麼preg_replace不工作?

$vars = '[picasa flashvars="host=picasaweb.google.com&hl=en_US&feat=flashalbum&RGB=0x000000&feed=https%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2F100016363917755589270%2Falbumid%2F5578059546640576577%3Falt%3Drss%26kind%3Dphoto%26hl%3Den_US" width="288" height="192"]'; 

$patterns[0] = "/\[picasa\] /"; 
$patterns[1] = "/\]/"; 

$replacements[0] = "<embed type='application/x-shockwave-flash' src='https://picasaweb.google.com/s/c/bin/slideshow.swf'"; 
$replacements[1] = " pluginspage='http://www.macromedia.com/go/getflashplayer'>"; 


$match = preg_replace($patterns,$replacements,$vars); 
echo $match; 

我知道我可以使用str_replace,但我想用preg_replace代替。

我在這裏做錯了嗎?

$patterns[0]比賽[picasa]這是不是在$vars

它應該是:

preg_replace('/\[picasa\s*([^\]]+)\]/',$replacements[0].'$1'.$replacements[1],$vars);
