在循环中创建一个多维数组

我试图在循环中创建这样的数组:
$dataPoints = array(
    array('x' => 4321, 'y' => 2364),
    array('x' => 3452, 'y' => 4566),
    array('x' => 1245, 'y' => 3452),
    array('x' => 700, 'y' => 900), 
    array('x' => 900, 'y' => 700));
用这个代码
$dataPoints = array();    
$brands = array("COCACOLA","DellChannel","ebayfans","google",
    "microsoft","nikeplus","amazon"); 
foreach ($brands as $value) {
    $resp = GetTwitter($value);
    $dataPoints = array(
        "x"=>$resp['friends_count'],
        "y"=>$resp['statuses_count']);
}
但是当循环完成时,我的数组看起来像这样:
Array ( [x] => 24 [y] => 819 ) 
    
已邀请:
这是因为您在每个循环上重新分配
$dataPoints
作为新数组。 将其更改为:
$dataPoints[] = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);
这将在
$dataPoints
末尾添加一个新数组     
使用
array_merge($array1,$array2)
简单地使用两个数组一个用于迭代,另一个用于存储最终结果。结帐代码。
$dataPoints = array();  
$dataPoint = array();  

$brands = array(
    "COCACOLA","DellChannel","ebayfans","google","microsoft","nikeplus","amazon"); 
foreach($brands as $value){
    $resp = GetTwitter($value);
    $dataPoint = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);
    $dataPoints = array_merge($dataPoints,$dataPoint);
}
    
$dataPoints[] = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);
    
每次迭代都要覆盖$ dataPoints变量,但是你应该向数组添加新元素......
$dataPoints[] = array("x"=>$resp['friends_count'],"y"=>$resp ['statuses_count']);
