for循环 php 增加数组维数_php实现给二维数组中所有一维数组添加值的方法

本文实例讲述了php实现给二维数组中所有一维数组添加值的方法。分享给大家供大家参考,具体如下:

给二维数组中所有的一维数组添加值(索引和关联)

$shop = array(

0=>array(0=>1,1=>2,2=>3,3=>4)

,1=>array(0=>1,1=>2,2=>3)

,2=>array(0=>1,1=>2,2=>3)

);

print_r($shop);

//示例 1:引用循环变量的地址赋值

foreach($shop as &$shoplist){

$shoplist[] = '4444444444444';

$shoplist['we'] = '欢迎光临脚本之家';

}

print_r($shop);

运行结果:

Array (

[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临脚本之家 )

[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )

[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )

)

//示例2:修改循环变量数组,重新赋值

foreach($shop as $key=>$shoplist){

$index = count($shoplist);

$shoplist[$index] = '4444444444444';

$shoplist['we'] = '欢迎光临脚本之家';

$shop[$key]=$shoplist;

}

print_r($shop);

运行结果:

Array (

[0] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 4444444444444 [we] => 欢迎光临脚本之家 )

[1] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )

[2] => Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4444444444444 [we] => 欢迎光临脚本之家 )

)

希望本文所述对大家PHP程序设计有所帮助。
