$cars=array("Volvo","BMW","SAAB",10,3.14,true); 如果访问其中值为10的这个元素，访问方式是$cars[ _____ ]?
举一反三
- $cars=array("Volvo"=>10,"BMW"=>5,"SAAB"=>23);___________可访问"BMW"对应的元素
- $cars=array( array("Volvo",22,18), array("BMW",15,13), array("Saab",5,2), array("LandRover",17,15) );
- 下列程序的执行结果是：<?php$cars=array("Volvo","BMW","Toyota");echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . ".";?>
- php[br][/br]$cars=array("Volvo","BMW","Toyota");[br][/br]echo "I like " . $cars[0] ;[br][/br]?>[br][/br](5.0) A: Volvo B: BMW C: Toyota
- $cars=array(array("Volvo",22,18),array...and Rover",17,15));
