如何用该URL中的参数值替换url？

Question

像：

$output = preg_replace( 
    "/http\:\/\/(.*)\?mid\=([0-9|a-z|A-Z]*)/ismU", 
    "<iframe src=\"http://professional.player.qbrick.com/player.aspx?mid=${2}\"></iframe>", 
    $output 
);

这不起作用......

我想要的是替换文本中的任何网址，如

http://professional.player.qbrick.com/player.aspx?mid=asdas23234ASD

与

<iframe src="http://professional.player.qbrick.com/player.aspx?mid=asdas23234ASD"></iframe>

Answer 1

您可以使用sprintf来构建字符串。

Answer 2

怎么样：

$output = 'http://professional.player.qbrick.com/player.aspx?mid=asdas23234ASD';
$output = preg_replace( 
    "#(http://.*?\?mid=[0-9a-zA-Z]+)\b#ismU", 
    "<iframe src=\"$1\"></iframe>", 
    $output 
);
echo $output,"\n";

<强>输出：

<iframe src="http://professional.player.qbrick.com/player.aspx?mid=asdas23234ASD"></iframe>
