I have a foreach loop like this.
if ( is_object($res_two)) {
if($res_two->num_rows() == 0) {
echo "No Records Found";}
else if( $res_two->num_rows() > 0) {
foreach ($res_two->result() as $row ) {
echo $row->js_id."\t". $row->designation."\t".$row->full_name."\t".$row->location."\t".$row->graduated_in."\t";
$mail2 = $row->email;
echo $mail2 ;
?> Download Resume <br/><br/> <?php
}
}
}
?>
Now I want to extract $mail2 details. However echoing $mail2 out of the code giving only one value instead of an array(if foreach loop iterates, it should have multiple values?).
How to get the multiple values of $mail2 outside the code?
<?php
if (is_object($res_two)) {
if ($res_two->num_rows() == 0) {
echo "No Records Found";
} else if ($res_two->num_rows() > 0) {
foreach ($res_two->result() as $row) {
echo $row->js_id . "\t" . $row->designation . "\t" . $row->full_name . "\t" . $row->location . "\t" . $row->graduated_in . "\t";
$mail2[] = $row->email;
?> Download Resume <br/><br/> <?php
}
}
}
print_r($mail2);
?>

I have 2 arrays: post_titles and posts. How do I print them one after another with foreach?
When I use 1 array, it works fine:
<?php foreach ($titles as $row) { ?>
<?php echo $row['post_title'] ?> <br>
<?php } ?>
I want data to be printed like this:
Title
Post
<br>
Title
Post
<br>
etc.
If each item in the titles and post correspond to each other (eg titles[1] and posts[1], titles[2] and posts[2]), you could use a for loop.
eg.
for($i = 0; $i < count($titles); $i++) {
echo $titles[$i];
echo $posts[$i];
echo "<br>";
}
or
foreach ($titles as $i => $value ){
echo $value ." <br>" . $posts[$i] . " <br>";
}
If the array have the same index key you can use this
<?php
foreach($titles as $key=> $value) {
echo $value . ' - ' $post[$key] . '<br>';
}
?>
If the 2 arrays are in sync i.e. the same length and arr1(0) equates to arr2(0) then its easy
<?php
foreach ($post_titles as $i => $title) {
echo $title . '<br>' . $posts[$i] . '<br>';
}
?>
Thanks for directing the link about the mySql API, i think there is a need to change to mySQLi or PDO. I have post the near-complete code below of same case, as my first time, could you please help what's error below, as it doesn't show the results as expected as the code using mysql_... please help. (assuming the select statement is correct please.)
<?php
$Ticker = htmlspecialchars($_GET["Ticker"]);
$StartDate = htmlspecialchars($_GET["StartDate"]);
$EndDate = htmlspecialchars($_GET["EndDate"]);
echo "<td>testing.</td>";
echo "</table>";
$pdo = new PDO('mysql:host=;dbname=, ,);
$statement = $pdo->query("Select Ticker, xxx as 'Last Update',Price, xxx as TTlUndetAmt,
FROM trade
WHERE Ticker = '$Ticker' and DATE(xxx) between '$StartDate' and '$EndDate'
GROUP BY Ticker, date
ORDER BY Ticker ASC, Date(ReleaseDT) DESC");
$row = $statement->fetch(PDO::FETCH_ASSOC);
//echo htmlentities($row['_message']);
echo "<table>";
while ($row = mysql_fetch_assoc($sql_result)) {
echo "<tr><td>";
foreach ($row as $value) {
if ($value === end($row)) {
echo number_format($value);
} else
{
echo $value . ",";
}
}
echo " </td></tr> " . "\n";
$i++;
}
?>
I got the results from select statement from mysql database. I use php to get the required data. I want specify the format only a specific item of each row to be numeric, i.e. (thousand separated). How could I do so? can below code do so?
Current output:
ticker1,2014-09-03 ,1.190,0,37247000
ticker2,2014-09-03 ,1.180,0,23246000
ticker3,2014-09-03 ,1.170,0,19188000
Expected Output:
ticker1,2014-09-03 ,1.190,0,37,247,000
ticker2,2014-09-03 ,1.180,0,23,246,000
ticker3,2014-09-03 ,1.170,0,19,188,000
The code I am using:
while ($row = mysql_fetch_assoc($sql_result)) {
echo "<tr><td>";
foreach ($row as $value) {
echo $value . ",";
if ($value === $row[5]) {
echo number_format($value);
}
}
echo " </td></tr> " . "\n";
$i++;
}
echo "</table>";
I found out that the above code will create duplicate role at the last row [5].
To my limited knowledge, I changed to
while ($row = mysql_fetch_assoc($sql_result)) {
echo "<tr><td>";
foreach ($row as $value) {
if ($value === end($row)) {
echo number_format($value);
} else
{
echo $value . ",";
}
}
echo " </td></tr> " . "\n";
$i++;
}
I would incorporate the key. That way, you can just check for the field name:
while ($row = mysql_fetch_assoc($sql_result)) {
echo "<tr><td>";
foreach ($row as $key => $value) {
echo $value . ",";
if ($key === 'YourFieldName') {
echo number_format($value);
}
}
echo " </td></tr> " . "\n";
$i++;
}
echo "</table>";
The function mysql_fetch_assoc already returns a key/value array, so you don't need anything there. Note though, that mysql_fetch_assoc is part of an old and deprecated API. If you like, have a look at: Choosing a MySQL API.
I would bring in the names, and use a $key=>$val in your foreach as such:
foreach ($row as $key=>$value)
{
echo $value . ",";
if ($key == "theRightColumn") // guessing the column name
{
echo number_format($val);
}
else
{
echo $val;
}
}
You have to change the modification in this line
foreach ($row as $value) {
to
foreach ($row AS $key => $value) {
I have a page on my site that shows a member directory. I want the members to be listed 3 per row, before it goes to the next row. The code I have, does this for the very first row - but on the second row, its all on one line and doesnt carry down.
The profiles are showing up like this:
uuu
uuuuuuuuuuuuuuuuuuuuuuuuuuu
When they should be doing this:
uuu
uuu
uuu
uuu
This is what my code looks like:
<table>
<tr>
<td colspan="4"><h1>Member Directory</h1></td></tr>
<tr>
<td>
<?php
while($row = mysql_fetch_array($result)) {
if (empty($row['profile']) === false){
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td><td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'] . "<br />";
echo '</td><td>';
if ($i++ == 2) echo '</td></tr><tr><td>';
}
?>
</td>
</tr>
</table>
Any help would be greatly appreciated, thanks!
Use
if (++$i % 3 == 0) echo '</td></tr><tr><td>';
Explanation:
First of all ++$i first increments $i, and then uses it in whatever is next, this makes for more readable code.
Second, the % is the modulus, which means it sortof subtracts 3 from $i until it is not possible anymore. E.g. 9 % 3 == 0, and 11 % 3 == 2 and so on. This means we know that we have printed 3 rows whenever $i % 3 equals 0.
try this one
<table>
<tr>
<td colspan="4"><h1>Member Directory</h1></td>
</tr>
<?php
$count=0;
while($row = mysql_fetch_array($result))
{
$count+=1;
if($count%3==1)
{
echo '<tr>';
}
echo '<td>';
if (empty($row['profile']) === false){
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td>';
echo '<td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'] . "<br />";
echo '</td>';
if($count%3==0)
{
echo '</tr>';
}
}
if($count%3!=0)
{
echo '</tr>';
}
?>
</table>
You didn't reset the value of $i, so it kept increasing; another issue is that if you have only seven items, the last row should have four empty cells. So the loop condition needs to be augmented with a row completion status:
$i = 0;
while (($row = mysql_fetch_array($result)) !== false || $i != 0) {
if ($i == 0) {
echo '<tr>'; // start of new row
}
if ($row !== false) {
echo '<td>';
if (empty($row['profile'])) {
echo '<img src="', $row['profile'], ' "width="125">';
} else {
echo '<img src="../../images/template/avatar.png">';
}
echo '</td><td>';
echo '' . ucfirst($row['username']) . '<br />';
echo "Location: " . $row['location'];
echo '</td>';
} else {
echo '<td></td><td></td>'; // no more data
}
$i = ($i + 1) % 3; // advance
if ($i == 0) {
echo '</tr>'; // end of the row
}
}
Would someone of you know why I'm not able to use a (long)piece of code within a foreach loop?
The code in the foreach loop is only executed once.
This code at topictweets.php works fine on its own but I want to repeat it for each forum.
The foreach loop works fine without the include. I also tried to have the code from topic tweets.php plainly in the foreach loop, this didn't work either of course.
The code it includes is used to get topics of a forum from the database and find related tweets, and save those in the database.
Is there some other way to do this?
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
include 'topictweets.php';
/////////
////////
}
online version: http://oudhollandsedrop.nl/webendata/FeedForum/fetchtweets.php

"Pasting" a bunch of code inside a loop isn't a great practice. In fact, what you're looking for is a function or the use of a defined class. So, if you can, define a function in your topictweets.php that will contain your code and use it in your loop:
include 'topictweets.php';
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
processYourForums($fID);
/////////
////////
}
try include_once()
however, why not have a loop within topictweets.php?
you can do the query, etc.. in this page, but then loop through it in the include
This should work fine:
include 'topictweets.php';
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
}
You only need to include once.
I have this while loop within another while loop in my PHP:
$selecty = mysql_query("SELECT * FROM followers WHERE userid='".$_SESSION['id']."'");
$rowsy = mysql_num_rows($selecty);
echo '<td>'. $table["username"]. '</td>';
echo '<td>';
while ($tables = mysql_fetch_assoc($selecty)) {
if($tables['followerid']!=$table['id']) {
echo ''.'';
} else {
echo ''.'';
}
}
echo '</td>';
echo "<tr>";
This is more of a logic question and whether or not a nested while loop is the right way to do it. What I'm trying to say is if the 'followerid' from 'user followers table' is not the same as the 'id' from users table (which is from the previous loop) - echo the follow button, else echo the following button.
This is working file while I have data in the followers table but If I don't nothing shows (as there are no rows) - How could I implement this in my PHP? So also if there are no rows in 'followers table' echo follow button?
you can try do it like that
$selecty = mysql_query("SELECT * FROM followers WHERE userid='".$_SESSION['id']."'");
$rowsy = mysql_num_rows($selecty);
echo '<td>'. $table["username"]. '</td>';
echo '<td>';
while ($tables = mysql_fetch_assoc($selecty)) {
if($tables['followerid']!=$table['id'] and $tables['followerid'] != '') {
echo '';
} else if($tables['followerid'] =$table['id'] and $tables['followerid'] !='') {
echo '';
} else {
echo what you like here when $tables['followerid'] = ''
}
}
echo '</td>';
echo "<tr>";
edit
class="follow">'.'</a>'
^------------you dont have to make point and single quotes here
$selecty = mysql_query("SELECT * FROM followers WHERE userid='".$_SESSION['id']."'");
$rowsy = mysql_num_rows($selecty);
echo '<table><tr>';
echo '<td>'. $table["username"]. '</td></tr>';
if ($tables['followerid'] !== ''){
while ($tables = mysql_fetch_assoc($selecty)) {
echo '<tr><td>';
if($tables['followerid']!=$table['id'] and $tables['followerid'] != '') {
echo '</td></tr>';
} else if($tables['followerid'] =$table['id'] and $tables['followerid'] !='') {
echo '</td></tr>';
} else {
echo "what you like here </td></tr>";
}
}
}
else {
echo "do your code here " ;
}
echo "</table>";
Put a boolean (FALSE) at the start of the 'followers' loop such that if it gets crossed make it TRUE. If you get outside the loop and it's still FALSE then add the button anyway.
$trip = FALSE;
while ($tables = mysql_fetch_assoc($selecty)) {
if($tables['followerid']!=$table['id']) {
echo ''.'';
} else {
$trip = TRUE;
echo ''.'';
}
}
if( !$trip ) echo '<a href="#" data-userid="'.$_SESSION['id'].'" class="follow">'.'</a
