常用选项
php -v
php -i PHP安装的有关信息
php -h 访问帮助文件
php -m 列出编译到当前PHP安装的所有模块

执行一段代码
php -r 'echo "hello, world!";'
php -r 'echo "Hello, World!\n";'
php -r '$ts = filemtime("/data/www/index.html");
> echo date("F j Y H:clear:s", $ts);'

php -r 'echo "Hello, world! \n\n";'

交互
php -a
echo 'hello world';
$arr = ['who', 'what', 'when'];
echo $arr[1];

创建命令行脚本
vim dummy.php

```
#!/usr/bin/php
<?php

// do whatever.
?>
This text is also displayed.
<?php

?>
```

php dummy.php


vim number.php
```
#!/usr/bin/php
<?php
$file = 'readme.txt';
echo "\nNumbering the file named '$file' ----------------\n\n";

$data = file($file);

$n = 1;

foreach($data as $line) {
	echo "$n $line";
	$n++;
}

echo "\n $file 文件结束\n";
```
运行的方式
php number.php
php -f number.php
chmod +x number.php
./number.php

检查语法, 但是不能检查严重错误
php -l number.php


使用命令行参数
vim number2.php
```
#!/usr/bin/php
<?php
if($_SERVER['argc'] == 2) {
	$file = $_SERVER['argv'][1];
	if(file_exists($file) && is_file($file)) {
		echo "\nNumbering the file named '$file' ----------------\n\n";
		if( $data = file($file) ){
		$n = 1;

		foreach($data as $line) {
			echo "$n $line";
			$n++;
		}

		echo "\n $file 文件结束\n";
			exit(0);
		} else {
			echo "文件不能读取\n";
		}
	} else {
		echo "文件不存在.\n";
		exit(1);
	}
} else {
	echo "\nUsage: number2.php <filename>\n\n";
	exit(1);
}
```

php number2.php filename

接受输入
vim init.php
```
#!/usr/bin/php
<?php

echo "\n请输入安装的一个模式?\n\n[0]开发模式\n[1]线上模式\n你选择[0-1, 或者\"q\"退出]";

if(fscanf(STDIN, '%d', $mode)==1) { //如果返回的结果不是1, 也就是没有读取一个数字, 脚本会执行else
	if($mode==0) {
		echo "\n你选择了开发模式, 进行开发模式配置\n";
	} else {
		echo "\n你选择了开发模式, 进行开发模式配置\n";
	}
} else {
    echo "\n请输入一个数字进行选择\n";
}
```


内置服务器

php -h  如果有大S和-t选项表示支持内置服务器  -t 指定网站根目录
php -S localhost:8080
php -S localhost:8080 -t /data/www

然后可以在浏览器中访问, 或者通过curl访问
Copy after login

The above has introduced the PHP command line interface, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
