php str_replace 替换为什么不成功？

跟着php100的视频做了这样一个小偷程序，偷的是问天网一个城市的天气预报，但是为什么替换远程文件不成功？

<?php
$url = "http://www.weather.com.cn/weather/101210505.shtml";
$op=@fopen($url,"r") or die ("超时");
$duqu=file_get_contents($url);

eregi("<div class=\"weatherYubao\" id=\"7d\">(.*)<div class=\"cleardiv\"></div>",$duqu,$fhz);

$fhz=str_replace("src=\"../images/\"","src=\"http://www.weather.com.cn/m/i/city/\"",$fhz);
echo $fhz[0];

?>

Answer 1

$fhz=str_replace("src=\"../images/\"","src=\"http://www.weather.com.cn/m/i/city/\"",$fhz);
改为
$fhz=str_replace("src=\"/m2/","src=\"http://www.weather.com.cn/m2/",$fhz);
