php 中可使用命令行变量--$argv和$argc
php 中可使用命令行变量。太多文字太抽象,用脚本来说话:
php
echo $argv[1]."\n";
echo $argv[2]."\n";
echo $argc."\n";
print_r($argv);
var_dump($argv);
?>
运行脚本时,命令行为:php argvtest.php TQ TQx
则输出结果为:
TQ
TQx //$argv是一个数组
3 //注意$argc变量,它用来保存$argv数组里元素的个数。要比正常输入的多一个,打印出来才知道,是多了一个脚本文件名称
Array
(
[0] => argvtest.php
[1] => TQ
[2] => TQx
)
array(3) {
[0]=>
string(12) "argvtest.php"
[1]=>
string(2) "TQ"
[2]=>
string(3) "TQx"
}
