PHP command-line scripting development

What PHP can do

PHP Official documents do not say PHP能做任何事 , this and the industry is widely circulated to the other programmers are not life is PHP是最好的语言 really distant call corresponding.

PHP is mainly used in the following three areas

(1) server-side scripting

This is the most important area, PHP parser (CGI or server module) and Web server (such as Apache, Nginx) with the use.

(2) Command line script

In this way, only the PHP parser is required to execute. Lenovo Python will understand.

(3) Desktop applications

With some extension libraries PHP-GTK you can use PHP to write desktop applications. But it's boring to do it.

Command line development

The following actions are performed under Mac

Enter the php directory, or php place the directory in an environment variable. (Mac ignores this step)

Execute a PHP file

php [-f] xxx.php

Can pass parameters

php [-f] xxx.php ‘hello‘ ‘world‘ 2015

Parameters passed to the script can be obtained in global variables $argv , and global variables have the $argc $argv number of member variables in the array (not the number of parameters passed to the script)

001.php

<?phpvar_dump($argc);echo "\n";var_dump($argv);?>

Perform 001.php

php 001.php ‘hello world‘ 2015

Output

int(3)array(3) {  [0]=>  string(7) "001.php"  [1]=>  string(11) "hello world"  [2]=>  string(4) "2015"}

You can also run the PHP code directly

php -r ‘echo "Hello World\n";‘#输出Hello World
