How to enable PHP scripts to accept input of options and values when executed in cli mode

: This article mainly introduces how to make PHP scripts accept input of options and values when executed in cli mode. if you are interested in PHP tutorials, refer to it. Users familiar with Linux should know that many Linux commands support input of options and values, such rm -f hello.txt, ls -al, netstat -tnlSo, how can I make PHP scripts support input of options and values during execution in cli mode? There are two methods:

Use the getopt () function

Assume that a PHP script is required to support three input options:
-A: value input is not accepted.
-B: accept value input
-C: accept value input, and this value is optional.

Based on the above requirements, you can write a PHP script:

Functionmain ($ args) {var_dump ($ args);}/** the option character is not followed by a colon, indicating that the option does not support value input *. the option character is followed by a colon, indicates that this option supports value input. * The option character is followed by two colons, indicating that this option supports value input. optional values include */$ args = getopt ('AB: c ::'); main ($ args );

Run the following command to execute the script: Linux is used as an example. assume that the script is named test. php. Note that the-f option is not required between./php and test. php:
./php test.php -a -b=valueOfB -c=valueOfC

Output:

Because the value of Option c is optional, let's try out what will happen if option c does not pass the value:

We can see that the array value corresponding to the option with no value is false.

Note that an equal sign (=) is used to connect options and values, or an equal sign (=) is omitted. you cannot use spaces to separate options and values. for example-b valueOfBOtherwise, the value may not be obtained.

getopt()It also supports options starting with two horizontal bars, such--aFor more information, seegetopt()$ Longopts

Use the $ argv variable

If you just want to pass some values to the script, you can use$argvThis variable, for more information about this variable, see: http://php.net/manual/zh/reserved.variables.argv.php

PHP script:

var_dump($argv);

Execute command./php test.php valueOfA valueOfB valueOfC

Output:

The above describes how to make PHP scripts input options and values acceptable for execution in cli mode, including some content, and hope to help those who are interested in PHP tutorials.
