//在以上字符串中，我要取出inet addr:192.168.8.9 Bcast之间的ip地址，请问php的正刚表达式怎么写？谢谢。
// $return_array 是以上字符串数组。

	foreach ( $return_array as $value )

	{

		//if ( preg_match( "/inet addr:/i", $value, $temp_array) )

		if ( preg_match("\binet addr:\b.*\bBcast\b", $value, $temp_array) )

		{

			echo '<br /><br />';

			print_r($temp_array);

			//var_dump( $temp_array );
