如何使用PHP将一个数组对象值推入循环内部

Question

我需要一个帮助。我需要在每次迭代中使用PHP将一个数组对象值推入另一个数组对象。我在下面解释我的代码。

for($i=0;$i<$len;$i++){ 
while($report=mysqli_fetch_assoc($reportqry)){ 
     $result[]=$report; 
    } 
    //$arry 
} 

在这里，我需要的$result将推入$arry在loop.Please的每次迭代中帮助我。

Answer 1

使用array_push功能（PHP Manual）

while($report=mysqli_fetch_assoc($reportqry)){ 
    array_push($result, $report); 
} 

Answer 2

$reportqry=mysqli_query(' some sql '); 

$len=5; 

$arry=array();/* was this defined before attempting to push items onto stack? */ 
$result=array();/* also define before loop */ 

for($i=0; $i < $len; $i++){ 
    while($report=mysqli_fetch_assoc($reportqry)){ 
     $result[]=$report; 
    } 
    $arry[]=$result; 
} 

我测试上面，它看起来像预期的那样工作 - 但我不是100％肯定我已经掌握的概念。

我的测试：

$sql='select `username`,`description` from `tasks`'; 
$results=$conn->query($sql); 
$len=3; 

$arry=array(); 
$result=array(); 

for($i=0; $i < $len; $i++){ 
    while($rs=$results->fetch_assoc()){ 
     $result[]=$rs; 
    } 
    $arry[]=$result; 
} 

打印$arry

Array 
(
    [0] => Array 
     (
      [0] => Array 
       (
        [username] => fred 
        [description] => banana 
       ) 
      [1] => Array 
       (
        [username] => joe 
        [description] => apple 
       ) 
      [2] => Array 
       (
        [username] => bertrum 
        [description] => orange 
       ) 
     ) 
    [1] => Array 
     (
      [0] => Array 
       (
        [username] => fred 
        [description] => banana 
       ) 
      [1] => Array 
       (
        [username] => joe 
        [description] => apple 
       ) 
      [2] => Array 
       (
        [username] => bertrum 
        [description] => orange 
       ) 
     ) 
    [2] => Array 
     (
      [0] => Array 
       (
        [username] => fred 
        [description] => banana 
       ) 
      [1] => Array 
       (
        [username] => joe 
        [description] => apple 
       ) 
      [2] => Array 
       (
        [username] => bertrum 
        [description] => orange 
       ) 
     ) 
) 

Answer 3

试试这个

for($i=0;$i<$len;$i++){ 
while($report=mysqli_fetch_assoc($reportqry)){ 

    array_push(result = $report); 
} 


//$arry 
}
