PHP getopt Operations
提问by Rachel
This question is regarding getopt function in php. I need to pass two parameter to the php scripts like
这个问题是关于 php 中的 getopt 函数的。我需要将两个参数传递给 php 脚本，例如
php script.php -f filename -t filetype
Now depending upon the file type which can be u, c or s I need to do proper operation.
现在根据可以是 u、c 或 s 的文件类型，我需要进行正确的操作。
I am using switch case for the same:
我正在使用 switch 案例：
Here is the Code I am using:
这是我正在使用的代码：
// Get filename of input file when executing through command line.
$file = getopt("f:t:");
Switch case should compare the type of the file which I am passing in from the command line (u, c or i) and accordingly match it and do the operation.
Switch case 应该比较我从命令行（u、c 或 i）传入的文件的类型，并相应地匹配它并执行操作。
switch("I am not sure what should go in there and this is wrong,Please advice")
{
case `Not sure`:
$p->ini();
break;
case `Not sure`:
$p->iniCon();
break;
case `Not sure`:
$p->iniImp();
break;
}
Kindly advise on this !!!
请就此提出建议！！！

If you just put something like this in your PHP script (called, on my machine, temp.php):
如果你只是在你的 PHP 脚本中加入这样的东西（在我的机器上调用temp.php）：
<?php
$file = getopt("f:t:");
var_dump($file);
And call it from the command-line, passing those two parameters :
并从命令行调用它，传递这两个参数：
php temp.php -f filename -t filetype
You'll get this kind of output :
你会得到这样的输出：
array(2) {
["f"]=>
string(8) "filename"
["t"]=>
string(8) "filetype"
}
Which means that :
意思就是 ：
$file['f']contains the value passed for-f- and
$file['t']contains the value passed for-t
$file['f']包含传递给的值-f- 并
$file['t']包含传递给的值-t
Starting from there, if you want your switchto depend on the option passed as the value of -t, you'll use something like this :
从那里开始，如果您希望switch依赖作为 的值传递的选项-t，您将使用以下内容：
switch ($file['t']) {
case 'u':
// ...
break;
case 'c':
// ...
break;
case 'i':
// ...
break;
}
Basically, you put :
基本上，你把：
- The variable that you want to test in the
switch() - And the possible values in the
cases
- 您要测试的变量
switch() - 以及
cases 中的可能值
And, for more informations, you can read, in the PHP manual :
而且，有关更多信息，您可以在 PHP 手册中阅读：
- The manual page of
switch - And
getopt()

I implemented a getopt parser for this, support short,long option names, type constraint, option printing.. etc. and this library has been maintained over 6 years.
我为此实现了一个 getopt 解析器，支持短、长选项名称、类型约束、选项打印等，并且这个库已经维护了 6 年多。
Synopsis:
概要：
<?php
use GetOptionKit\OptionCollection;
use GetOptionKit\OptionParser;
$options = new OptionCollection;
$spec = $options->add( 'f|foo:' , 'option require value' ); # returns spec object.
$options->add( 'b|bar+' , 'option with multiple value' );
$options->add( 'z|zoo?' , 'option with optional value' );
$options->add( 'f|foo:=i' , 'option require value, with integer type' );
$options->add( 'f|foo:=s' , 'option require value, with string type' );
$options->add( 'v|verbose' , 'verbose flag' );
$options->add( 'd|debug' , 'debug flag' );
$parser = new OptionParser;
$result = $parser->parse( array( 'program' , '-f' , 'foo value' , '-v' , '-d' ) );
$result = $parser->parse( $argv );
$spec = $result->verbose;
$spec = $result->debug;
$spec->value; # get value
GetOptionKit\OptionPrinter can print options for you:
GetOptionKit\OptionPrinter 可以为您打印选项：
* Available options:
-f, --foo option requires a value.
-b, --bar option with multiple value.
-z, --zoo option with optional value.
-v, --verbose verbose message.
-d, --debug debug message.
--long long option name only.
-s short option name only.
Demo
演示
Please check examples/demo.php.
请检查examples/demo.php。
Run:
跑：
% php examples/demo.php -f test -b 123 -b 333
Print:
打印：
* Available options:
-f, --foo <value> option requires a value.
-b, --bar <value>+ option with multiple value.
-z, --zoo [<value>] option with optional value.
-v, --verbose verbose message.
-d, --debug debug message.
--long long option name only.
-s short option name only.
Enabled options:
* key:foo spec:-f, --foo <value> desc:option requires a value.
value => test
* key:bar spec:-b, --bar <value>+ desc:option with multiple value.
Array
(
[0] => 123
[1] => 333
)

There is a problem in your approach. What if user gives following command line by mistake. the script will not be able to detect it and fail as $file['t']will be an array.
你的方法有问题。如果用户错误地给出了以下命令行怎么办。脚本将无法检测到它，并且会像$file['t']数组一样失败。
php temp.php -f filename -t filetype -f filename2
