<br />$arr=array();<br />$arr['imagePath']="";<br />$arr['Size1']="";<br />$arr['imageaPath']="";<br />$arr['image2Path']="";<br />$arr['Size33']="";<br />$arr['image5Path']="";<br />$arr['Size55']="";<br />$arr['imagebbPath']="";<br />$arr['imageccPath']="";<br />$arr['Size555']="";<br />$arr['imageqqPath']="";<br />$arr['image99Path']="";<br />$arr['imageeePath']="";<br />$arr['imagepPath']="";<br />$arr['Size66']="";<br /><br /><br />$url='/';<br />$arr['imagePath']=$url;<br />$arr['imageaPath']=$url;<br />$arr['image2Path']=$url;<br />$arr['image5Path']=$url;<br />$arr['imagebbPath']=$url;<br />$arr['imageccPath']=$url;<br />$arr['imageqqPath']=$url;<br />$arr['image99Path']=$url;<br />$arr['imageeePath']=$url;<br />$arr['imagepPath']=$url;<br />

------解决方案--------------------
这有什么“怪”呢？
看上去也还算清晰明了

foreach($ar as $k=?&$v) if(substr($k, -4) == 'Path') $v = $url;
