Question

我想从foreach php循环中创建一维JSON输出。但是我当前的代码是打印以逗号分隔的单独JSON。

我正在使用PHP 5.5.38版本

<?php

$phone_num = $_GET["phonenum"];

// Initialize variable for database credentials
$dbhost = 'localhost';
$dbuser = 'xxxx';
$dbpass = 'yyyy';
$dbname = 'zzzz';

$connect = mysql_connect("localhost","xxxx","yyyy") or die('Database Not Connected. Please Fix the Issue! ' . mysql_error());
mysql_select_db("zzzz", $connect);
$querycallid = "SELECT CallSid FROM show_details WHERE phone_number = $phone_num ORDER BY CallSid DESC LIMIT 10";
$callid = mysql_query($querycallid, $connect);
$carray=array();

while($callidres = mysql_fetch_object($callid))
{
    $carray[] = $callidres->CallSid;
}

$carray=array_filter($carray);

$dblink = new mysqli($dbhost, $dbuser, $dbpass, $dbname);

if ($dblink->connect_errno)
{
    printf("Failed to connect to database");
    exit();
}

//Initialize array variable
$pdbdata = array();

$presult = $dblink->query("SELECT patient_name, age, disease, contact_no, sex FROM show_header WHERE phone_number = $phone_num");

//Fetch into associative array
while($prow=$presult->fetch_assoc())
{
    $pdbdata[]=$prow;
}

$dbdata = array();
foreach($carray as $id)
{
    //Fetch comments from show_details table
    $result = $dblink->query("SELECT datetime, comment FROM show_details WHERE CallSid = $id");

    //Fetch into associative array
    $dbdata[] = $result->fetch_assoc();
}

$farray = array_merge($pdbdata, $dbdata);


 //Print array in JSON format
$farray =  str_replace(array('[', ']'), '', htmlspecialchars(json_encode($farray), ENT_NOQUOTES));;

echo $farray;

?>

我的预期结果应该是这样。

{
"patient_name":"Mike",
"age":"26",
"disease":"arthritis",
"contact_no":"9876543210",
"sex":"Male",
"datetime":"07-16-2019 11:57:39",
"comment":"day 2 comment 1",
"datetime":"06-15-2019 15:09:01",
"comment":"patient wants appointment for tomorrow",
"datetime":"05-10-2019 12:07:34",
"comment":"comment 1",
}

但是我的当前结果显示如下。

{
"patient_name":"Mike",
"age":"26",
"disease":"arthritis",
"contact_no":"9876543210",
"sex":"Male"
},

{
"datetime":"07-16-2019 11:57:39",
"comment":"day 2 comment 1"
},

{
"datetime":"06-15-2019 15:09:01",
"comment":"patient wants appointment for tomorrow"
},

{
"datetime":"05-10-2019 12:07:34",
"comment":"comment 1"
}

我尝试将数组与$pdbdata和$dbdata之类的代码中的各种结果分开，然后合并到一个JSON中。但是它仍然显示输出，并用逗号分隔。请帮助我解决代码中的错误。
