php 指針賦值

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

楼主的问题是？

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

这种赋值方法好像有点怪怪的

$url='/';
$arr['imagePath']=$url;
$arr['imageaPath']=$url;
$arr['image2Path']=$url;
$arr['image5Path']=$url;
$arr['imagebbPath']=$url;
$arr['imageccPath']=$url;
$arr['imageqqPath']=$url;
$arr['image99Path']=$url;
$arr['imageeePath']=$url;
$arr['imagepPath']=$url;

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;

请教
$k= ?&$v ？？

$k=>&$v
不好意思，按错了键

地址引用，我咋没想到！！！！！好办法啊！

不引用也是一样的

foreach($ar as $k=>$v) if(substr($k, -4) == 'Path') $ar[$k] = $url;
