  phpstr_replace() 函数使用正则
字符串如下:

“http:\/\/www.sina.com\/music1\/23412455.mp3?time=2234523&type=mp3”
“http:\/\/www.sina.com\/music2\/4325243.mp3?time=2234523&type=mp3”
“http:\/\/www.sina.com\/music3\/346553.mp3?time=2234523&type=mp3”

需要对http开始,?结束之间的字符串换成“abc”,在php的str_replace函数里,该如何写?谢谢                            

------解决方案--------------------
str_replace 用不了正则,用preg_replace 吧
------解决方案--------------------

$urls = array("http:\/\/www.sina.com\/music1\/23412455.mp3?time=2234523&type=mp3",
"http:\/\/www.sina.com\/music2\/4325243.mp3?time=2234523&type=mp3",
"http:\/\/www.sina.com\/music3\/346553.mp3?time=2234523&type=mp3");
foreach($urls as $url){
	echo preg_replace([email protected](.*?)\[email protected]','abc',$url).'
';
}
