单个维度多维阵列中的PHP

Question

$结果包含3个单维阵列

Array ([0] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 
Array ([0] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 
Array ([0] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 

我想要的结果：

Array ([0] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 
Array ([1] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 
Array ([2] => http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg) 

Answer 1

溶液1：

$new_array = array(); 
foreach($results as $key => $value){ 
$new_array[] = $value[0]; 
} 

或：

$new_array = array(); 
foreach($results as $key => $value){ 
$new_array[] = $value; 
} 

但第一种解决方案更好，因为您的数组包含每个值的单个值。

Answer 2

使用array_merge

$arr1=array("http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg"); 
$arr2=array("http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg"); 
$arr3=array("http://ecx.images-amazon.com/images/I/51z0h9unmsL._SL160_.jpg"); 
$arr=array_merge($arr1,$arr2,$arr3);
