Question

我在while循环中使用两个查询，因此得到两个数组，我想要将它们合并为单个数组。这是我的代码。请告诉我我错在哪里？

<?php
While ($row = mysql_fetch_assoc($query8)) {
    $res1 = mysql_query("select * from tablename where ... ");
    $res11 = mysql_fetch_assoc($res);
    $res2 = mysql_query("select * from tablename where ... ");
    $res22 = mysql_fetch_assoc($res2);
}
total = array_merge($res11, $res22);
$responseJSON = array(
    "response" => total
);
header("content - type: application / json");
response = json_encode($responseJSON);
echo response;

Answer 1

初始化$ res11 = []之前的

;和$ res22 = [];

 $res11[]=mysql_fetch_assoc($res)
 $res22[] = mysql_fetch_assoc($res2);

写下这些并尝试。

Answer 2

要说出你想做什么有点难，我猜是这样的：

$query8 = mysql_query("select * from table name where ...");

$res1 = array();
$res2 = array();
while($row0=mysql_fetch_assoc($query8)) {
    $res1[] = $row0;
    $row1 = mysql_fetch_assoc($query8)
    $res2[] = $row1;
  }

$total=array_merge($res1,$res2);

$responseJSON = array("response" => $total);

header("content-type:application/json");

$response = json_encode($responseJSON);

echo $response;

数组合并功能在while循环中不起作用
