How to add a <br/> after each result, but not last result? - php

This is my partial code:
while($row = $db->fetch_array($query))
{
echo $row['row_name'];
}
How can I make it so it will add a break tag after each result, but not the last result?

Put the output into an array, then join the array with implode:
$rows = array();
while($row = $db->fetch_array($query))
{
$rows[] = $row['row_name'];
}
echo implode('<br/>', $rows);

You could do this. No arrays or counters.
if($row = $db->fetch_array($query))
{
do {
echo $row['row_name']
} while($row = $db->fetch_array($query) && print("<br />"));
}

for ($idx = 0; $row = $db->fetch_array($query); $idx++)
{
if ($idx > 0) { echo "<br/>"; }
echo $row['row_name'];
}

encode php recordset in custom format

I'm currently have a recordset created with dreamweaver and have encode the results in json format which work fine.
Recordset
$maxRows_rs_feeds = 3;
$pageNum_rs_feeds = 0;
if (isset($_GET['pageNum_rs_feeds'])) {
$pageNum_rs_feeds = $_GET['pageNum_rs_feeds'];
}
$startRow_rs_feeds = $pageNum_rs_feeds * $maxRows_rs_feeds;
mysql_select_db($database_vivalooks, $vivalooks);
$query_rs_feeds = "SELECT fname,lname FROM profile";
$query_limit_rs_feeds = sprintf("%s LIMIT %d, %d", $query_rs_feeds, $startRow_rs_feeds, $maxRows_rs_feeds);
$rs_feeds = mysql_query($query_limit_rs_feeds, $vivalooks) or die(mysql_error());
$row_rs_feeds= mysql_fetch_assoc($rs_feeds);
if (isset($_GET['totalRows_rs_feeds'])) {
$totalRows_rs_feeds = $_GET['totalRows_rs_feeds'];
} else {
$all_rs_feeds = mysql_query($query_rs_feeds);
$totalRows_rs_feeds = mysql_num_rows($all_rs_feeds);
}
$totalPages_rs_feeds = ceil($totalRows_rs_feeds/$maxRows_rs_feeds)-1;
do {
echo json_encode($row_rs_feeds);
} while ($row_rs_feeds = mysql_fetch_assoc($rs_feeds));
mysql_free_result($rs_feeds);
Recordset Results
{"fname":"Benjamin","lname":"Blay"}{"fname":"Alfread","lname":"Mark"}{"fname":"yaa","lname":"tiwaa"}
But i want the results to be encode like this rather
[{"fname":"Benjamin","lname":"Blay"},{"fname":"Alfred","lname":"Mark"},{"fname":"yaa","lname":"tiwaa"}]
Try
do {
$json[]=json_encode($row_rs_feeds);
} while ($row_rs_feeds = mysql_fetch_assoc($rs_feeds));
echo "[".implode(", ", $json)."]";
OR
do {
$rows[] = $row_rs_feeds;
} while ($row_rs_feeds = mysql_fetch_assoc($rs_feeds));
echo json_encode($rows);
You can change your loop to look like this:
echo "[";
$count = 0;
do {
if($count !== 0)
echo ",";
$count++;
echo json_encode($row_rs_feeds);
} while ($row_rs_feeds = mysql_fetch_assoc($rs_feeds));
echo "]";
$count is there just to skip first "," so you don't get [,{...},{...}] or you can put it like false/true... I just can't remember right now what is better in case you have 10k steps loop...
Try:
do {
$rows[] = $row_rs_feeds;
} while ($row_rs_feeds = mysql_fetch_assoc($rs_feeds));
echo json_encode($rows);

Echo array values of column not working

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;
}
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 $row_dc['Datecode'];
}
}
Note:- mysql is deprecated instead use mysqli or PDO
else {
while ($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> $Datecode";
}
}
-first array don't print value using echo
-use print_r($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++;
}
NOTE::-- Use single Quote instead of double Quote and mysql is deprecated instead use mysqli or PDO

Fetch Two Arrays in 1 while loop (not working)

I'm trying to fetch arrays from two queries. The result only gets the first index.
while(($row2 = mysql_fetch_array($query1)) && ($index = mysql_fetch_array($query2)))
{
$leaveID = $row2['leaveID'];
$personID = $index['personID'];
$Person_Type = $index['Person_Type'];
if ($Person_Type == 'Regular')
{
$Sick_Remaining_Days = 10 - $Sick_Total_Days;
}else{
$Sick_Remaining_Days = 5 - $Sick_Total_Days;
}
echo "<tr>";
echo ($leaveID == $personID) ? "<td>$Sick_Remaining_Days</td>" : "<td>--</td>";
echo "</tr>";
}
Assuming both queries are OK I offer two ways to loop through them depending on your needs. Hopefully one of them will help.
<?php
$arrayRowA = array();
$arrayRowB = array();
while($row = mysql_fetch_array($query1)){$arrayRowA[] = $row;}
while($row = mysql_fetch_array($query2)){$arrayRowB[] = $row;}
// Loop through two arrays in a square way (every combination of both arrays)
foreach($arrayRowA as $keyA => $objectA){
foreach($arrayRowB as $keyB => $objectB){
$leaveID = $objectA['leaveID'];
$personID = $objectB['personID'];
$Person_Type = $objectB['Person_Type'];
if($Person_Type == 'Regular')
{
$Sick_Remaining_Days = 10 - $Sick_Total_Days;
}else{
$Sick_Remaining_Days = 5 - $Sick_Total_Days;
}
echo "<tr>";
echo ($leaveID == $personID) ? "<td>$Sick_Remaining_Days</td>" : "<td>--</td>";
echo "</tr>";
}
}
// Loop through two arrays in a linear way (one to one)
foreach($arrayRowA as $keyA => $objectA){
if(isset($arrayRowB[$keyA])){
$objectB = $arrayRowB[$keyA];
$leaveID = $objectA['leaveID'];
$personID = $objectB['personID'];
$Person_Type = $objectB['Person_Type'];
if($Person_Type == 'Regular')
{
$Sick_Remaining_Days = 10 - $Sick_Total_Days;
}else{
$Sick_Remaining_Days = 5 - $Sick_Total_Days;
}
echo "<tr>";
echo ($leaveID == $personID) ? "<td>$Sick_Remaining_Days</td>" : "<td>--</td>";
echo "</tr>";
}
}
?>
$query = mysql_query("select p*, l* from person as p left join leave as l on p.personID = l.leaveID");
while(($row = mysql_fetch_array($query)))
{
$Person_Type = $row['Person_Type'];
if ($Person_Type == 'Regular')
{
$Sick_Remaining_Days = 10 - $Sick_Total_Days;
}else{
$Sick_Remaining_Days = 5 - $Sick_Total_Days;
}
echo "<tr>";
echo "<td>$Sick_Remaining_Days</td>";
echo "</tr>";
}
You should get array before while:
array f,s
while(first)
{
f = ...;
}
while(second)
{
s = ...;
}
And now use both array.
Or try use new http://php.net/manual/en/mysqli-result.fetch-array.php. Probably you losing connection to first query after use second query.
while($row = mysqli_fetch_assoc($result))
{
$row2 = mysqli_fetch_assoc($result2);
echo $row['id'];
echo $row2['id'];
/* your code */
} `
Use this... It is what do you search !
while($row2 = mysql_fetch_array($query1))
{
$index = mysql_fetch_array($query2);
echo $row['id'];
echo $index['id'];
/* add code */
}

HTML select not inflating correctly from PHP array

I am trying to create a drop down menu of usernames or a <select> as it's known in HTML. However I am only getting the last value back from my array and I can't figure out why.
PHP
function getUserName($db) {
try {
$sql = 'SELECT members.name FROM members';
$query_an = $db->query($sql);
$count = $query_an->rowCount();
if ($count > 0) {
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names = array();
$names[] = $row['name'];
}
return $names;
}
} catch(PDOException $e) {
die($e->getMessage());
}
}
HTML
<select>
<?php $names = getUserName($db); foreach($names as $key => $value) { ?>
<option value="<?php echo $key ?>"><?php echo $value ?></option>
<?php }?>
</select>
I'm fairly sure the HTML section of my code is solid. I think the error lies in how I'm adding values to my $names array but after staring at it for a half an hour I can't see it. Thanks for any help/fresh eyes.
You need to declare your array outside the loop
if ($count > 0) {
$names = array();
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names[] = $row['name'];
}
return $names;
}
this is emptying your array every time : $names = array();
use this :
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names[] = $row['name'];
}
You are creating a new $names array every row then returning the last one. You need to declare the array outside the while loop. The following should work:
function getUserName($db) {
try {
$sql = 'SELECT members.name FROM members';
$query_an = $db->query($sql);
$count = $query_an->rowCount();
if ($count > 0) {
$names = array();
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names[] = $row['name'];
}
return $names;
}
} catch(PDOException $e) {
die($e->getMessage());
}
}
The problem is you're re-initializing the array on every loop:
See:
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names = array();
$names[] = $row['name'];
}
return $names;
Should be:
$names = array();
while ($row = $query_an->fetch(PDO::FETCH_ASSOC)) {
$names[] = $row['name'];
}
return $names;

static marker from a mysql array

I have a little problem I can't figure out how to solve.
I have an SQL result with 3 rows and I want to put the id from each row into a static marker ie.
MARKER_1 = 4
MARKER_2 = 5
MARKER_3 = 6
How can I do that so I get my static markers but with dynamic values?
I can't do it with a normal
while($row = mysql_fetch_array($result)) {
}
$i = 1;
while($row = mysql_fetch_array($result)) {
if($i == 1) {
$marker_1 = $row;
} elseif($i == 2) {
$marker_2 = $row;
} elseif($i == 3) {
$marker_3 = $row;
}
$i++;
}
i would recommend using an array like this
$results = array();
while($row = mysql_fetch_array($result)) {
$results[] = $row;
}
and then access it via:
$results[0] // or $results[1] and so on. you can even loop that :)
hope that helps
Hope this helps
while($row = mysql_fetch_array($result)) {
echo "MARKER_".$row['id'];
echo"=". $row['value'];
}
