我在json数组中创建了mysql记录，但json数据集似乎存在一些问题。 PFB代码： -
JSON输出来了： -
[{
"ID": "1",
"Coupon_ID": "ABC1",
"Campaign_ID": "353",
"Campaign_Name": "Test1",
"Title": "Test1",
"Description": "Test1",
"Category": "Test1",
"Type": "Coupon",
"Type_Value": "1231",
"Tracking_URL": "http://abc1.com",
"Added_Date": "2016-07-13",
"Expiry_Date": "2016-07-28"
}][
{
"ID": "2",
"Coupon_ID": "ABC2",
"Campaign_ID": "3532",
"Campaign_Name": "Test2",
"Title": "Test2",
"Description": "Test2",
"Category": "Test2",
"Type": "Coupon",
"Type_Value": "1232",
"Tracking_URL": "http://abc2.com",
"Added_Date": "2016-07-13",
"Expiry_Date": "2016-07-28"
}]
我想要这样的事情： -
[{
"ID": "1",
"Coupon_ID": "ABC1",
"Campaign_ID": "353",
"Campaign_Name": "Test1",
"Title": "Test1",
"Description": "Test1",
"Category": "Test1",
"Type": "Coupon",
"Type_Value": "1231",
"Tracking_URL": "http://abc1.com",
"Added_Date": "2016-07-13",
"Expiry_Date": "2016-07-28"
}
{
"ID": "2",
"Coupon_ID": "ABC2",
"Campaign_ID": "3532",
"Campaign_Name": "Test2",
"Title": "Test2",
"Description": "Test2",
"Category": "Test2",
"Type": "Coupon",
"Type_Value": "1232",
"Tracking_URL": "http://abc2.com",
"Added_Date": "2016-07-13",
"Expiry_Date": "2016-07-28"
}]
我的意思是[]这些括号而不是每个记录，这些只应该出现一次。
PHP代码： -

您需要在while循环之外初始化/回显JSON数组：
$json = array();
while(....) {
while(....) {
//.......
array_push($json, $value);
//.......
}
}
echo json_encode($json, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

我只是更改你的代码，试试这段代码，希望你能得到预期的结果。
<?php
header('Content-type: application/json');
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "couponsdeals";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$apikey = $_GET['API_KEY'];
$sql = "SELECT AFF_ID FROM api WHERE API_KEY= '$apikey' ";
//$sql1= "SELECT ID,Coupon_ID,Campaign_ID,Campaign_Name,Title,Description,Category,Type,Type_Value,Tracking_URL,Added_Date,Expiry_Date FROM couponcode_table ";
$sql1= "SELECT * FROM couponcode_table ";
$result = $conn->query($sql);
$result1 = $conn->query($sql1);
if ($result) {
// output data of each row
$json = array();
while($row = $result->fetch_assoc()) {
$data= $row["AFF_ID"];
if($result1){
while($row1 = $result1->fetch_assoc()) {
$data1=$row1["Tracking_URL"];
$mydata = explode("&",$data1);
if(isset($mydata[2])){
$mydata2= $mydata[0]."&aff_id=".$data."&".$mydata[2];
$values =array(
'ID' => $row1['ID'],
'Coupon_ID' => $row1['Coupon_ID'],
'Campaign_ID' => $row1['Campaign_ID'],
'Campaign_Name' => $row1['Campaign_Name'],
'Title' => $row1['Title'],
'Description' => $row1['Description'],
'Category' => $row1['Category'],
'Type' => $row1['Type'],
'Type_Value' => $row1['Type_Value'],
'Tracking_URL' =>$mydata2,
'Added_Date' => $row1['Added_Date'],
'Expiry_Date' => $row1['Expiry_Date']
);
array_push($json, $values);
} else {
$mydata1= $mydata[0]."&aff_id=".$data;
$value =array(

如果您打算获取循环中生成的所有数据，您可能只需将所有数据存储在变量中，并将输出echo $whatever;与脚本末尾和循环外部区分开来。这样你就可以一次性获取所有数据...下面稍微修改并注释了你的代码更好地说明了这一点
<?php
header('Content-type: application/json');
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "couponsdeals";
// CREATE A VARIABLE THAT WOULD HOLD ALL THE DATA (ARRAY GENERATED IN THE LOOP)
// INITIALIZE IT TO THE DEFAULT "FAILURE" MESSAGE..."0 Results"
// THAT WAY; YOU WOULDN'T NEED ANY else if() CLAUSE...
$jsonData = array("message"=> "0 results");
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$apikey = $_GET['API_KEY'];
$sql = "SELECT AFF_ID FROM api WHERE API_KEY= '$apikey' ";
$sql1 = "SELECT * FROM couponcode_table ";
$result = $conn->query($sql);
$result1 = $conn->query($sql1);
$json = array();
$json1 = array();
if ($result) {
// output data of each row
while($row = $result->fetch_assoc()) {
$data = $row["AFF_ID"];
if($result1){
while($row1 = $result1->fetch_assoc()) {
$data1 = $row1["Tracking_URL"];
$mydata = explode("&",$data1);
if(isset($mydata[2])){
$json1 = array();
$mydata2 = $mydata[0]."&aff_id=".$data."&".$mydata[2];
$values = array(
'ID' => $row1['ID'],
'Coupon_ID' => $row1['Coupon_ID'],
'Campaign_ID' => $row1['Campaign_ID'],
'Campaign_Name' => $row1['Campaign_Name'],
'Title' => $row1['Title'],
'Description' => $row1['Description'],
'Category' => $row1['Category'],
'Type' => $row1['Type'],
'Type_Value' => $row1['Type_Value'],
'Tracking_URL' => $mydata2,
'Added_Date' => $row1['Added_Date'],
'Expiry_Date' => $row1['Expiry_Date']
);
// PUSH DATA TO THE $json1 VARIABLE
// AND DO NOT OUTPUT IT HERE YET... DIFFER IT
// TO THE END OF THE SCRIPT.
array_push($json1, $values);
}else{
$json = array();
$mydata1 = $mydata[0]."&aff_id=".$data;
$value = array(
'ID' => $row1['ID'],
'Coupon_ID' => $row1['Coupon_ID'],
'Campaign_ID' => $row1['Campaign_ID'],
'Campaign_Name' => $row1['Campaign_Name'],
'Title' => $row1['Title'],
'Description' => $row1['Description'],
'Category' => $row1['Category'],
'Type' => $row1['Type'],
'Type_Value' => $row1['Type_Value'],
'Tracking_URL' => $mydata1,
'Added_Date' => $row1['Added_Date'],
'Expiry_Date' => $row1['Expiry_Date']
);
// PUSH DATA TO THE $json VARIABLE
// AND DO NOT OUTPUT IT HERE YET... DIFFER IT
// TO THE END OF THE SCRIPT...
array_push($json, $value);
}
}
}
}
// NOW; OVERRIDE THE $jsonData VARIABLE WE CREATED ABOVE
// AND CREATE 2 ELEMENTS WITHIN IT 'json1' & 'json2'
// TO HOLD THE VALUES GENERATED WITHIN THE IF & ELSE CLAUSE RESPECTIVELY:SET ITS VALUE TO THE $json
$json = (!empty($json)) ? $json : array("message"=>"Empty Data-set for json");
$json1 = (!empty($json1)) ? $json1 : array("message"=>"Empty Data-set for json1");
// ASSIGN DATA FROM $json & $json1 TO THE $jsonData ARRAY...
$jsonData = array(
"json" => $json,
"json1" => $json1,
);
}
// NO NEED FOR ELSE CLAUSE BECAUSE IF THE "IF CLAUSE" DOES NOT RUN;
// WE HAVE A DEFAULT FOR THE $jsonData WHICH HAS A MESSAGE KEY
// CONTAINING THE DEFAULT MESSAGE WITHIN AN ARRAY...
// CLOSE DB CONNECTION
$conn->close();
// ECHO OUT THE JSON-ENCODED DATA AND EXIT THE SCRIPT USING DIE...
die( json_encode($jsonData, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES) );
