php 中可使用命令行变量。太多文字太抽象,用脚本来说话:
 

 
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" }
