Perl 学习心得体会

首先是在windows平台上使用，可以下载ActivePerl或者StrawberryPerl，安装后既可以像在linux下进行命令行运行了（没有图形界面，呵呵！）

Perl 中的特殊变量 $&, $`,$' ,@_：http://blog.csdn.net/bjbs_270/archive/2007/09/20/1792360.aspx

下面的内容来时学习《Advanced Perl Programming》

Chapter 1

dynamically and statically allocated storage
anonymous storage
reference and dereference
scalars, arrays, hashes

%sue = (
' name ' => ' Sue ' ,
' age ' => ' 45 ' ,
' children ' => [ # anonymousarray
{ # anonymoushash1
' name ' => ' John ' ,
' age ' => ' 20 '
} ,
{ # anonymoushash2
' name ' => ' Peggy ' ,
' age ' => ' 16 '
}
]
);

print $sue {children} -> [ 1 ] -> {name};

Chapter 2

http://www.perl.com/doc/FMTEYEWTK/(http://www.perl.com/doc/FMTEYEWTK/regexps.html)

# twodimensionarrayimplement
%foo1 = (a => 10 , str => " good " );

$a = 0 ;
$str = 1 ;
$foo2 [ $a ] = 10 ;
$foo2 [ $str ] = " hello " ;

print " $foo1{str} " ;
print " $foo2[$str] " ;

# complexstructure
$student { 0001 } = {
name => fei ,
course => []};

print $student { 0001 }{name};

看到第二章，发现内容是在是太深了，还是先看看《Perl Programming》吧。尤其是正则表达式，一定要好好学习。
