多維數(shù)組的問題,請(qǐng)教一下.

kaixin9ok

#!/usr/bin/perl
$chenjun{"test"} = ["1","2","3","4","5","6","7"];
while (($file,@value) = each %chenjun)
{
        print $file;
        foreach $test (@value){
        print $test . "\n";
        }
}

....
ARRAY(0x9fdcc2
打印結(jié)果總是這個(gè)
我應(yīng)該如何做才能最終得到數(shù)組里的1，2，3，4，5，6，7這些值 ?

1. $value = $chenjun{"test"};
   
2. foreach (@$value) {
   
3.         print $_;
   
4. }

$value = $chenjun{"test"};
foreach (@$value) {
        print $_;
}
   

沒太明白這么寫是什么意思?

這樣做一次付值 是什么意思 ？
為什么不能直接這樣寫呢？
#!/usr/bin/perl
$chenjun{"test"} = ["1","2","3","4","5","6","7"];
$value = $chenjun{"test"};
foreach ($chenjun{"test"}) {
        print $_;
}

   

mcshell

1. map{print $_ for @{$chenjun{$_}}}keys %chenjun

    嗯  多謝多謝

  剛試了一下這樣寫
while ( $key = each %chenjun){
        foreach (@{$chenjun{$key}}){
                print $_;
        }



}

$chenjun{"test"} = ["1","2","3","4","5","6","7"];

$chenjun{"test"} 中存儲(chǔ)的是數(shù)組的引用，需要解引用
