count value is changes on every refresh.
How to i store count value in variable and use in "for loop" over here $x <= 10;
<?php
echo "<div class='p_list_heading'> Product Name </div>";
echo "<div class='p_list_heading'> Product Price </div>";
echo "<div class='p_list_heading'> Product Quantity </div>";
echo count($_SESSION['product_name']);
for ($x = 0; $x <= 10; $x++) {
if($_SESSION['product_name'][$x]!==""){
echo "<div class=\"c_hold\">";
echo "<div>".#$_SESSION['product_name'][$x]."</div>";
echo "<div>".#$_SESSION['product_price'][$x]."Rs". "</div>";
echo "</div>";
}
}
?>
Store in some variable $y
$y = count($_SESSION['product_name']);
for ($x = 0; $x <= $y; $x++) {
if($_SESSION['product_name'][$x]!==""){
echo "<div class=\"c_hold\">";
echo "<div>".#$_SESSION['product_name'][$x]."</div>";
echo "<div>".#$_SESSION['product_price'][$x]."Rs". "</div>";
echo "</div>";
}
}
Instead of storing in variable, you can also do:
for ($x = 0; $x <= count($_SESSION['product_name']); $x++) {
if($_SESSION['product_name'][$x]!==""){
echo "<div class=\"c_hold\">";
echo "<div>".#$_SESSION['product_name'][$x]."</div>";
echo "<div>".#$_SESSION['product_price'][$x]."Rs". "</div>";
echo "</div>";
}
}
Please try following:
$count = count($_SESSION['product_name']);
echo $count;
for ($x = 0; $x <= $count; $x++)
{
}

PHP: How do you determine every Nth iteration of a loop?

Closed last year.
I had a little problem, i cannot break the table because I'm looking for a 16 columns in these table to create a unicode table...
The aim is to find where i must break the line of the column as like as there:
<?php
$columnas = 16;
$filas = 16;
$word= 0;
$contador = 0;
print "<table border=\"1\">\n";
print "<caption>ASCII</caption>\n";
print "<tbody>\n";
print "<tr>\n";
for ($j = 1; $j <= $columnas; $j++){
if ($j%2 == 1){
print "<th>Codigo</th>\n";
}elseif ($j%2 == 0){
print "<th>Valor</th>\n";
}
}
print "</tr>";
for ($i = 1; $i <= $filas; $i++){
for($i = 1; $i <= 50000; $i++,$contador){
$unicodeChar = "&#{$i}";
$contador--;
print "<td>" .$i. "</td>\n";
print "<td>".$unicodeChar."</td> \n";
}
print "</tr>\n";
}
print "</tbody>\n";
print "</table>\n";
?>
enter image description here
You used the modulus in the first loop, so use it again in the second
print "</tr>";
print "<tr>";
for($i = 1; $i <= 50000; $i++){
$unicodeChar = "&#{$i}";
$contador--;
print "<td>$i</td><td>$unicodeChar</td>\n";
if ( $i % $columnas/2 ) == 0 ) {
print "</tr><tr>\n";
}
}
print "</tr>\n";
Thank you very much for this help, i have been fixed!!
here is the code that i fixed, with your idea :)

if (($i % 8 ) == 0 ){
print "</tr><tr>";
}
}
print "</tr>\n";
}
print "</tbody>\n";
print "</table>\n";

Like Riggsfolly said but maybe divide the columns number by 2 before the modulo, because there are 2 TDs / iteration:
if ( $i % ($columnas/2) ) == 0 ) {
print "</tr><tr>\n";
}
I made a script where it creates a pyramid using a php for loop and html table elements, but the pyramid isn't how I want it yet.
The code:
<?php
echo "<table width=400px";
echo "<tr>";
//Inner Loop
for ($x = 0; $x <= 8; $x++) {
//Outer loop
for ($z = 1; $z <= $x; $z++) {
echo "<td height=50px width=50px bgcolor=black></td>";
}
echo "\n";
echo "</tr>";
}
echo "</table>";
?>
Right now it looks like this:
But I want it to look like this:
Can someone help me with that?
Simply add cellspacing=0 to table
<?php
echo "<table cellspacing=0 width=400px";
echo "<tr>";
//Inner Loop
for ($x = 0; $x <= 8; $x++) {
//Outer loop
for ($z = 1; $z <= $x; $z++) {
echo "<td height=50px width=50px bgcolor=black></td>";
}
echo "\n";
echo "</tr>";
}
echo "</table>";
?>
I have to make a diamond-shaped asterisk using for loop, inside a table. It has to have "blank" <td> spaces before and after the asterisks to move and make it look centered, so it looks like a diamond. How do I do that? (I used PHP inside an HTML code.)
Code without the <tr> and <td> tags, it looked like a diamond because it was center aligned:
<center>
<?php
echo "<table border = 1>";
// loop for the pyramid
for($i = 1; $i <= 10; $i += 2) {
for($j = 1; $j <= $i; $j++) {
echo "* ";
}
echo "<br />";
}
// loop for the inverted pyramid, so it looks like a diamond
for($i = 7; $i >= 1; $i -= 2) {
for($j = 1; $j <= $i; $j++) {
echo "* ";
}
echo "<br />";
}
echo "</table>";
?>
</center>
Code with the <tr> and <td> tags, need "spaces" for it to look like it's center aligned:
<?php
echo "<table border = 1>";
// loop for the pyramid
echo "<tr>";
for($i = 1; $i <= 10; $i += 2) {
echo "<tr>";
for($j = 1; $j <= $i; $j++) {
echo "<td>* </td>";
}
echo "</tr>";
}
echo "</tr>";
// loop for the inverted pyramid, so it looks like a diamond
for($i = 7; $i >= 1; $i -= 2) {
echo "<tr>";
for($j = 1; $j <= $i; $j++) {
echo "<td>* </td>";
}
echo "<br />";
echo "</tr>";
}
echo "</table>";
?>
Please help!
Here is new Code with your solution. I have added logic to put blank td forward and backward to *
<?php
echo "<table border = 1>";
// loop for the pyramid
echo "<tr>";
$max = $initAmount = 10;
for($i = 1; $i <= $initAmount; $i += 2) {
$max = $max -2;
$halfTD = (int)$max/2;
echo "<tr>";
for($b = 1; $b <= $halfTD; $b++){
echo "<td></td>";
}
for($j = 1; $j <= $i; $j++) {
echo "<td>* </td>";
}
for($b = 1; $b <= $halfTD; $b++){
echo "<td></td>";
}
echo "</tr>";
}
echo "</tr>";
// loop for the inverted pyramid, so it looks like a diamond
$max = $initAmount = 10;
for($i = 7; $i >= 1; $i -= 2) {
$max = $max -2;
$diff = $initAmount - $max;
$blankTd = $diff/2;
echo "<tr>";
for($b = 1 ; $b <= $blankTd; $b++){
echo "<td></td>";
}
for($j = 1; $j <= $i; $j++) {
echo "<td>* </td>";
}
for($b = 1 ; $b <= $blankTd; $b++){
echo "<td></td>";
}
echo "</tr>";
}
echo "</table>";
?>
I used the code below without using a table to make a diamond shape.
<div style="text-align: center">
<?php
$n = 8;
if($n === 1){ die("input must be greater than 1"); }
$nn = ($n * 2);
$m = (ceil($nn / 2) + 1);
$temp = 0;
for($x = 1; $x <= $nn; $x++){
$temp = (($x < $m) ? ($temp + 1) : ($temp - 1));
$total = ($temp > 1 ? ((2 * $temp) - 1) : $temp);
echo nl2br(str_repeat('* ', $total) . "\r\n");
}
?>

I want to iterate an array of data using foreach loop.
However, I want the first 4 results to display two items per row.Thereafter I want the rest of the data to display I item per row
i found a possible solution here
$data = range(1, 30);
for($count = 0; $count < count($data);)
{
echo "<tr>\n";
for($i = 0; $count < count($data) && $i < 2; $count++, $i++) {
echo "\t<td>$data[$count]</td>\n";
}
for(; $i < 2; $i++) {
echo "\t<td>-</td>\n";
}
echo "</tr>\n";
}
how the problem with this code is that it displays all the data in rows of two.i however only want the first 4 results to display that way.
You can do something like this:
$data = range(1, 30);
for($count = 0; $count < count($data); ++$count){
if($count < 4){
if($count % 2 == 0){
echo "<tr><td>" . $data[$count] . "</td>";
}else{
echo "<td>" . $data[$count] . "</td></tr>";
}
}else{
echo "<tr><td>" . $data[$count] . "</td></tr>";
}
}
Here's the demo
You're using the already incremented $i variable twice.
$i is never < 2
Add this instead
for($j = 0; $j < 2; $j++) {
echo "\t<td>-</td>\n";
}
Test here
Try with -
$data = range(1, 30);
for($count = 0; $count < count($data); $count++)
{
echo "<tr>";
if($count < 2) {
for($i = 1; $i <= 2; $i++) {
echo "<td>" . $data[$count] . "</td>";
if($i == 1) {
echo "</tr><tr>";
}
}
} else {
echo "<td>" . $data[$count] . "</td>";
}
echo "</tr>";
}
What about something like this?
echo '<table border=1>';
$data = range(1, 30);
for($count = 0; $count < count($data); $count++){
echo "<tr>\n";
if($count < 4) {
echo "\t<td>$data[$count]</td>\n";
$count++;
echo "\t<td>$data[$count]</td>\n";
} else {
echo "\t<td colspan=2>$data[$count]</td>\n";
}
echo "</tr>\n";
}
echo '</table>';
I want to make in html page like this below:
But, I don't want to write them all one by one, because the number(1, 2, 3) are from $number variable and it can be more than 3.
Use a for loop:
for ($i = 1; $i <= $number; $i++) {
echo "<a href='$i'";
if ($i == $currentvid) {
echo " class='currentvid'";
}
echo "></a>";
}
Try this:
<?php
$href="1";
for($i=1;$i<4;$i++){
if($href==$i){
echo "$i";
}else{
echo "$i";
}
}
?>
$i = 1;
foreach ($number as $k)
{
if($i == 1)
{
echo "$i";
}
else
{
echo "$i";
}
}
}
