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' => [ #anonymous array
{ #anonymous hash 1
'name' => 'John',
'age' => '20'
},
{ #anonymous hash 2
'name' => 'Peggy',
'age' => '16'
}
]
);
print $sue{children}->[1]->{name};
'name' => 'Sue',
'age' => '45',
'children' => [ #anonymous array
{ #anonymous hash 1
'name' => 'John',
'age' => '20'
},
{ #anonymous hash 2
'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)
#two dimension array implement
%foo1 = (a => 10, str => "good");
$a = 0;
$str = 1;
$foo2[$a] = 10;
$foo2[$str] = "hello";
print "$foo1{str} ";
print "$foo2[$str] ";
#complex structure
$student{0001} = {
name => fei,
course => [] };
print $student{0001}{name};
%foo1 = (a => 10, str => "good");
$a = 0;
$str = 1;
$foo2[$a] = 10;
$foo2[$str] = "hello";
print "$foo1{str} ";
print "$foo2[$str] ";
#complex structure
$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。
正则表达式30分钟入门教程 (相当不错的教程,虽然作者是.Net开发者)
