$arguments = getopt("a:b:c:");
可以用下面的方式运行脚本(有无空格是没有关系的,注意看第一个例子和第二个例子):
php test.php -a app -b bar -c carORphp test.php -aapp -bbar -ccar
print_r($arguments) 将返回:
Array( [a] => app [b] => bar [c] => car)
注意:
1.冒号是需要的
2.如果没有指明值,在数组里面就不会出现
还是刚才的例子:
php test.php -a app
print_r($arguments) :
Array( [a] => app)
关于长参数
早于php 5.3的版本,如果使用长参数(--name=value 或--name value),很可能会得到如下的错误信息:
PHP Warning: getopt(): No support for long options in this build in ...
因此,如果php的版本早于5.3最好还是使用短参数。
