How to add values to all one-dimensional arrays in a two-dimensional array in php
This article mainly introduces the method of PHP to add values to all one-dimensional arrays in a two-dimensional array, involving PHP's array traversal, conversion, assignment and other related operating skills. Friends who need it can refer to it
The details are as follows:
Add values (indexes and associations) to all one-dimensional arrays in the two-dimensional array
$shop = array(
0=>array(0=>1,1=>2,2=>3,3=>4)
,1=>array(0=>1,1=>2,2=>3)
,2=>array(0=>1,1=>2,2=>3)
);
print_r($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);Running results:
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);Running results:
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 ) )
