Echo array values of column not working - php

Question

I want to display the values of my array. but instead of displaying:
1509 1510 1511 it display ArrayArrayArray. What does it mean?
include("db_PSIS.php");
$sql_dc = "SELECT Child, Datecode
FROM traveller_merging15
WHERE Parent='" . $_REQUEST["txt_traveller_no"] . "'
ORDER BY Merge_ID ASC";
$res_dc = mysql_query($sql_dc);
$dcode1 = $row_dc['Datecode'];
$storeArray = array();
if (!$res_dc) {
echo "No data fetched!";
} else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$storeArray[] = $dcode1;
echo "{$storeArray} <br>";
}
//$str_dc=implode(",",$storeArray);
//echo $str_dc;
}

Answer 1

You are assign the value of $row_dc['Datecode']; before fetch data from database. You need to do fetch data inside while loop and echo it
$res_dc = mysql_query($sql_dc);
if (!$res_dc) {
echo "No data fetched!";
} else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
echo $row_dc['Datecode'];
}
}
Note:- mysql is deprecated instead use mysqli or PDO

Answer 2

else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$storeArray[] = $dcode1;
echo "{$storeArray} <br>";
}
instead try
else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$storeArray[] = $dcode1;
echo "{$storeArray[0]} <br>";
}

Try this,
else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$child = $row_dc['Child'];
$Datecode = $row_dc['Datecode'];
echo "$child <br> $Datecode";
}
if you are getting more that 1 row, use for() loop
else {
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$count = count($row_dc);
for($i = 0; $i < $count; $i ++){
$child = $row_dc[$i]['Child'];
$Datecode = $row_dc[$i]['Datecode'];
echo "$child <br> $Datecode";
}
}

Answer 4

-first array don't print value using echo
-use print_r($array) to print key value pair(print a array)
your solution is
$i = 0;
while ($row_dc = mysql_fetch_array($res_dc, MYSQL_ASSOC)) {
$storeArray[$i] = $dcode1;
echo $storeArray[$i].'<br>';
$i++;
}
