I have the following code:
var_dump(explode(',',$_POST['colum_names']));
echo '<table border="1">';
$result = $con->query("" . $_POST['sql_command'] . "");
while($row = $result->fetch_array()) {
echo '<tr>';
...
echo '</tr>';
}
echo '</table>';
Inbetween the echo '<tr>' and echo '</tr>' I wish to be able to use the explode array hard to explain...
So for example it might look like:
$_POST['colum_names'] = a,b,c
=> array(3) { [0]=> string(1) "a" [1]=> string(1) "b" [2]=> string(1) "c" }
=> echo '<tr>'; echo $row[array[0]]; echo '</tr>';
=> echo '<tr>'; echo $row[array[1]]; echo '</tr>';
=> echo '<tr>'; echo $row[array[3]]; echo '</tr>';
If you get what I mean, I hope you can help!
$columns = explode(',',$_POST['colum_names']);
echo '<table border="1">';
$result = $con->query("" . $_POST['sql_command'] . "");
while($row = $result->fetch_array()) {
echo '<tr>';
foreach( $columns as $column ) {
echo '<td>' . $column . '</td>';
}
echo '</tr>';
}
echo '</table>';
Untested but should work

I am able to display all the array elements using the code below but I would like to know how can I display several array elements only (for example 4th, 6th and 11th). Could you please help me.
$rates = $data->Rates->ExchangeRate;
if (is_array($rates) && count($rates) > 0) {
echo '<table><tr><th>ISO</th><th>Rate</th></tr>';
foreach ($rates as $rate) {
echo '<tr>';
echo '<td>' . $rate->ISO . '</td><td>' . $rate->Rate . '</td></tr>';
echo '</tr>';
}
echo '</table>';
}
Just make an array of allowable key values and everytime check if the current key is included:
$rates = $data->Rates->ExchangeRate;
$allow = array(4,6,11);
if (is_array($rates) && count($rates) > 0) {
echo '<table><tr><th>ISO</th><th>Rate</th></tr>';
foreach ($rates as $key => $rate) {
if(!in_array($key, $allow){
continue;//if not allowed, go to next iteration
}
echo '<tr>';
echo '<td>' . $rate->ISO . '</td><td>' . $rate->Rate . '</td></tr>';
echo '</tr>';
}
echo '</table>';
}
You could filter the array in any number of ways before iterating over it, or you could use a condition inside the loop
$rates = $data->Rates->ExchangeRate;
if (is_array($rates) && count($rates) > 0) {
echo '<table><tr><th>ISO</th><th>Rate</th></tr>';
$count = 0;
$show = array(4, 8, 11);
foreach ($rates as $rate) {
if ( in_array($count++, $show) ) {
echo '<tr>';
echo '<td>' . $rate->ISO . '</td><td>' . $rate->Rate . '</td>';
echo '</tr>';
}
}
echo '</table>';
}
Other answers have given solutions but i think are slower than one posted here (use an array of included indices i.e $included_indices = array(4,6,11);):
$rates = $data->Rates->ExchangeRate;
if (is_array($rates) && count($rates) > 0) {
echo '<table><tr><th>ISO</th><th>Rate</th></tr>';
foreach ($included_indices as $included_indice) {
$rate = $rates[$included_indice];
echo '<tr>';
echo '<td>' . $rate->ISO . '</td><td>' . $rate->Rate . '</td></tr>';
echo '</tr>';
}
echo '</table>';
}
the roblem is where there is the punch commentator
i need when the column has INTER name or OUTER name to format the content of the $cell
with $cell=number_format($cell,2,',','.')
i'm just starting using php so don be too specific thanks
<?php
// printing table rows
$rigapadi = 1 ;
while($row = mysql_fetch_row($result))
{
echo "<tr>";
$rigapadi=$rigapadi+1;
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
if ($rigapadi % 2 == 0) {
# if column name = 'INTER' or 'OUTER' $cell = number_format($cell, 2, ',', '.');
echo "<td align=\"center\">$cell</td>";
} else {
echo "<td bgcolor=\"#E9EEF5\" align=\"center\">$cell</td>";
}
echo "</tr>\n";
}
mysql_free_result($result);
echo "</table>";
echo "<p/>";
?>
The mysql_ are obsoltes. You must not use them. And please indent your code properly when you ask for help.
<?php
$rigapadi = 1;
while($row = mysql_fetch_assoc($result)) {
echo '<tr>';
$rigapadi++;
foreach($row as $name => $cell) {
if($rigapadi % 2 === 0) {
if($name === 'INTER' || $name === 'OUTER') {
echo '<td align="center">' . number_format($cell, 2, ',', '.') . '</td>';
} else {
echo '<td align="center">' . $cell . '</td>';
}
} else {
echo '<td align="center" bgcolor="#E9EEF5">' . $cell . '</td>';
}
}
echo "</tr>\n";
}
mysql_free_result($result);
echo "</table>";
?>
Note that I use fetch_assoc to get the $name.
PS: <p/> does not exists and align and bgcolor and not valids but acceptable if this is a HTML code for an e-mail.
I'm trying to parse the arrivals table from here [1] and put in into an array to be able to format it and put it into a table.
I did some research here and there, I've got some code from other questions, but I can't make the array and table look as I'd like.
Anyone can help me out?
<?php
require('simple_html_dom.php');
$html = file_get_html('http://flightplan.romatsa.ro/init/fpl/flightslr/LRCL/');
$table = $html->find('table', 3);
foreach($table->find('tr') as $row) {
// initialize array to store the cell data from each row
$rowData = array();
foreach($row->find('td') as $cell) {
// push the cell's text to the array
$rowData[] = $cell->innertext;
}
echo "<table>";
echo "<td>";
echo $rowData[0]. " ";
echo "</td>";
echo "<td>";
echo $rowData[1]. " ";
echo "</td>";
echo "<td>";
echo $rowData[2]. " ";
echo "</td>";
echo "<td>";
echo $rowData[3]. " ";

Maybe try putting each row into an array and then each cell into another array. Hopefully, that will do what you want.
require('simple_html_dom.php');
$html = file_get_html('http://flightplan.romatsa.ro/init/fpl/flightslr/LRCL/');
$table = $html->find('table', 3);
$rowData = array();
foreach($table->find('tr') as $row) {
// initialize array to store the cell data from each row
$flight = array();
foreach($row->find('td') as $cell) {
// push the cell's text to the array
$flight[] = $cell->plaintext;
}
$rowData[] = $flight;
}
echo '<table>';
foreach ($rowData as $row => $tr) {
echo '<tr>';
foreach ($tr as $td)
echo '<td>' . $td .'</td>';
echo '</tr>';
}
echo '</table>';
Note: this solution requires the simple_html_dom.php library. Get it here!
Currently I have a table order by
A B C D
E F G H
but I would like to order the table by
A E
B F
C G
D H
Code:
for($i=0;$i<=count($aFiles);$i++)
{
if($i%5==0)
{
echo "</tr><tr>";
}
echo '<td><a>'.$aFiles[$i].'</a></td>';
}
echo '</tr>';
echo '</table>';
Files are already sorted a-z in $aFiles.
$aFiles = array('a','b','c','d', 'e', 'f', 'g');
$iColumnNumber = 2;
$iRowMaxNumber = ceil(count($aFiles) / $iColumnNumber);
$iTableRow = 0;
$iTableColumns = 1;
$aTableRows = array();
// make array with table cells
foreach ($aFiles as $sFile)
{
if ($iTableRow == $iRowMaxNumber)
{
$iTableRow = 0;
$iTableColumns++;
}
if (!isset($aTableRows[$iTableRow]))
{
$aTableRows[$iTableRow] = array();
}
$aTableRows[$iTableRow][] = '<td>' . $sFile . '</td>';
$iTableRow++;
}
// if there is odd number of elements
// we should add empty td elements
for ($iTableRow; $iTableRow < $iRowMaxNumber; $iTableRow++)
{
if (count($aTableRows[$iTableRow]) < $iTableColumns)
{
$aTableRows[$iTableRow][] ='<td>empty</td>';
}
}
// display table
echo '<table>';
foreach ($aTableRows as $aTableRow)
{
echo '<tr>';
echo implode('', $aTableRow);
echo '</tr>';
}
echo '</table>';
Simple Approach using HTML trick:
echo '<div class="tbl_group"><table>';
for($i=0;$i<=count($aFiles / 2);$i++)
{
echo '<tr>';
echo '<td><a>'.$aFiles[$i].'</a></td>';
echo '</tr>';
}
echo '</tr>';
echo '</table></div>';
echo '<div class="tbl_group"><table>';
for($i=$aFiles / 2;$i<=count($aFiles);$i++)
{
echo '<tr>';
echo '<td><a>'.$aFiles[$i].'</a></td>';
echo '</tr>';
}
echo '</tr>';
echo '</table></div>';
For the CSS:
.tbl_group {
float: left;
}
With this approach, 2 tables are built side-by-side. float: left CSS will auto adjust the position of the tables.
Assuming you know the number of rows you want, you don't need to resort anything, just add some logic in your loop that generates the <td>s :
$size = count($aFiles);
echo '<table><tr>';
for($i=0;$i<=ceil($size/2);$i++) {
if($i%2==0) {
echo '<td><a>'.$aFiles[$i].'</a></td>';
echo "</tr><tr>";
} else {
if(isset($aFiles[$i+floor($size/2)])) {
echo '<td><a>'.$aFiles[$i+floor($size/2)].'</a></td>';
}
}
}
echo '</tr></table>';
Example bellow also works with associative array + arrays with odd elements.
Code for associative AND indexed array :
$aFiles = ['test'=>"A","B",'c'=>"C","D","E","F",'g'=>"G","H",'iii'=>"I"];
$aKeys = array_keys($aFiles);
$aRows = ceil(count($aFiles) / 2);
echo '<table>';
for($i=0; $i < $aRows; $i++) {
echo
'<tr>' .
' <td>' . $aFiles[$aKeys[$i]] . '</td>' .
' <td>' . (isset($aKeys[$i+$aRows]) ? $aFiles[$aKeys[$i+$aRows]] : 'empty') . '</td>' .
'</tr>';
}
echo '</table>';
Code for ONLY indexed array :
$aFiles = ["A","B","C","D","E","F","G","H","I"];
$aRows = ceil(count($aFiles) / 2);
echo "<table>";
for($i=0; $i < $aRows; $i++) {
echo
"<tr>" .
" <td>" . $aFiles[$i] . "</td>" .
" <td>" . (isset($aFiles[$i+$aRows]) ? $aFiles[$i+$aRows] : "empty") . "</td>" .
"</tr>";
}
echo "</table>";
Output for both examples is identical :
<table>
<tr>
<td>A</td>
<td>F</td>
</tr>
<tr>
<td>B</td>
<td>G</td>
</tr>
<tr>
<td>C</td>
<td>H</td>
</tr>
<tr>
<td>D</td>
<td>I</td>
</tr>
<tr>
<td>E</td>
<td>empty</td>
</tr>
</table>
Not optimized, but this should more or less work:
$aFiles = array ("A","B","C","D","E","F","G","H","I","J","K","L","M","N",);
$rows = 4;
$columns = floor((count($aFiles)/$rows))+1;
echo '<table>';
for ($i=0;$i<$rows;$i++) {
echo '<tr>';
for ($j=0;$j<$columns;$j++) {
echo '<td>';
if (isset($aFiles[$i+$j*$rows]))
echo $aFiles[$i+$j*$rows];
else
echo " ";
echo '</td>';
}
echo '</tr>';
}
echo '</table>';
You can change the number of rows if you want.
Try this one. Assume that your $aFiles contains a-z alphabetically.
for ($i = 0; $i < count($aFiles/2); $i++){
echo '<tr><td><a>'.$aFiles[$i].'</a><td><td><a>'.$aFiles[$i+13].'</a><td></tr>'
}
I have a MySQL query that returns data using PHP.
My problem is that I need to populate my html table (with 3 columns) with the data returned by the query but the data should be populated Columnwise.
Like first the first column should be populated .. then the second and finally the third one.
Also I would like to know that is it possible to do so for an unlimited set of data?
Following the screen shot of the desired layout
you can use while.
<table>
$sql=mysql_query("select * from table");
while($s=mysql_fetch_array($sql))
{
$x=$s["x"];
<tr>
<td ><?php echo $x; ?></td>
<td ><?php echo $y; ?></td>
<td ><?php echo $z; ?></td>
</tr>
}
</table>
guybennet's answer is correct but if you want it to work for an unlimited amount of columns you could do this: (I also threw in some column headers for readability)
echo '<table>';
$counter = 0;
$result = mysql_query("select * from table");
while($row = mysql_fetch_array($result)) {
$counter++;
if($counter == 1) {
echo '<tr>';
foreach($row as $key => $val) {
echo "<th>$key</th>";
}
echo '</tr>';
}
echo '<tr>';
foreach($row as $key => $val) {
echo "<td>$val</td>";
}
echo '</tr>';
}
echo '</table>';
Also of course you should use mysqli or PDO I'm just showing a quick example.
If you don't care about how it's organized, you can try something like this:
echo "<table><tr>";
$i=0;
while($row = mysql_fetch_array($sql))
{
echo "<td>".$row[0]."</td>\n";
$i++;
if($i==3)
{
echo "</tr>\n<tr>";
$i=0;
}
}
echo "</tr></table>";
Otherwise, I'd suggest putting it all into an array and then putting it into the table.
$data = array();
$result = mysql_query("SELECT * FROM your_table");
while ($row = mysql_fetch_array($result)) {
$data[] = $row;
}
$itemsAmount = count($data);
$ceilAmount = ($itemsAmount - $itemsAmount % 3) / 3;
$lastAmount = $itemsAmount % 3;
$firstArray = array_slice($data, 0, $itemsAmount);
$secondArray = array_slice($data, 0, $itemsAmount*2);
$thirdArray = array_slice($data, 0, $lastAmount);
$output = "<table>";
foreach ($data as $key => $value) {
$output .= "<tr>";
$output .= "<td>" . $firstArray[$key][0] . "</td>";
$output .= "<td>" . $secondArray[$key][0] . "</td>";
if (empty($thirdArray[$key])) {
$str = '';
} else {
$str = $thirdArray[$key][0];
}
$output .= "<td>" . $str . "</td>";
$output .= "</tr>";
}
$output .= "</table>";
echo $output;
You need to check all the results returned, then print them as you won't print in order:
First get an array with all the results
<?php
$sql= mysql_query('SELECT * FROM table');
$num= mysql_affected_rows($sql);
$items = array();
$i=0;
while($item=mysql_fetch_array($sql)){
$items[++$i]=$item['data'];
}
Now start printing
int $num_rows;
$num_rows=$num%3;
echo '<table>';
for ($i=0;$i<$num_rows;$i++){
echo '<tr>';
for ($j=0;$j<2,$j++){
$n=$i+1+($j*$num_rows);
if($items[$n]!==null)
echo '<td>'.$items[$n].'</td>';
else
echo '<td></td>';
}echo '</tr>';
}echo'</table>';
?>
