PHP数组和explode函数应用实例

PHP数组和explode函数应用实例，供大家学习参考。

例1：

3. $province = array("北京","上海","天津","重庆","河北","山西","内蒙古","辽宁","吉林","黑龙江","江苏","浙江","安徽","福建","江西","山东","河南","湖北","湖南","广东","广西","海南","四川","贵州","云南","西藏","陕西","甘肃","宁夏","青海","新疆","香港","澳门","台湾","其他");

4. echo count($province);//数组成员个数
5. echo "
   ";

6. if(is_array($province)){//检测变量是否是数组

7. echo "嗯,真是个数组啊";
8. }
9. echo "
   ";

10. for($index=0;$indexecho $province[$index];

11. echo "
    ";
12. }
13. ?>

例2：

3. //利用 explode 函数分割字符串到数组

4. $source = "hello1,hello2,hello3,hello4,hello5";//按逗号分离字符串
5. $hello = explode(',',$source);

6. for($index=0;$indexecho $hello[$index];echo "
   ";

7. }
8. ?>

例3：

2. //函数挺实用的
3. // 分隔符可以是斜线，点，或横线
4. $date = "04/30/1973";
5. list($month, $day, $year) = split ('[/.-]', $date);
6. echo "Month: $month; Day: $day; Year: $year
   \n";
7. ?>
