I run this program, but I need the output within table. So would you please solve this?
<?php
$s="*";
for($b=1; $b<=5; $b++) {
for($c=5; $c>=$b-1; $c--) {
if($c>=$b) {
echo $s;
}
else if($b != 1) {
echo " ";
}
}
for($d=5; $d>=$b; $d--) {
echo $s;
}
echo "<br/>";
}
?>
If you're fine regardless of how the code was written (only results matter), you can use this:
print('<table>');
for ($i = 0; $i < 5; $i++)
{
print('<tr>');
for ($j = 1; $j <= 5; $j++)
{
print('<td>');
(5 - $i >= $j) ? print('*') : '';
print('</td>');
}
for ($j2 = 1; $j2 <= 5; $j2++)
{
print('<td>');
(1 + $i <= $j2) ? print('*') : '';
print('</td>');
}
print('</tr>');
}
print('</table>');
What I did there is I sliced table in half vertically and used 2 for loops to fill left and right halfs. You will get something like this:

I'm supposed to use nested for loops to create this shape: https://imgur.com/a/prh6zwj
This is what I currently have:
<?php
for ($x = 1; $x <= 10; $x++){
for ($y = 1; $y <= 6; $y++){
echo "Y";
}
}
?>
I have no clue what to do.
Thanks in advance!
<?php
$position = 1;
for ($x = 1; $x <= 11; $x++){
for ($y = 1; $y <= 6; $y++){
if ($y == $position) {
echo "Y";
} else {
echo "0";
}
}
if ($x < 6) {
$position++;
} else {
$position--;
}
echo "\n";
}
<?php
$length = 6; // change this to change height width
$pos = 0;
for ($x = 1; $x <= (($length*2)-1); $x++){
if($x <= $length)
{$pos = $pos+1; }
else
{$pos = $pos-1; }
for ($y = 1; $y <= $length; $y++){
if($y == $pos)
echo "Y";
else
echo "O";
}
echo "\n";
}
There are many possible ways to achieve this when I started programming I never cared about the code quality and just focused on the output. I have added two examples to help you understand it better!
<?php
//We have 6 columns & 11 rows so we need two loops one size of 11 and second size of 6
$counter = 1;
for ($i = 1; $i <= 11; $i++){
for ($j = 1; $j <= 6; $j++){
if ($j == $counter) {
echo "Y";
} else {
echo "O";
}
}
if ($i < 6) {
$counter++;
} else {
$counter--;
}
echo "<br/>";
}
echo "**************************** METHOD TWO ****************************";
//Following is not efficient But its also printing the same results
for ($i = 0 ; $i < 66 ; $i++){
if($i == 65)
{
echo "O";
break;
}
if($i % 6 == 0){
echo "<br/>";
}
if($i <= 36)
{
if ($i % 7 == 0){
echo "Y";
}else{
echo "O";
}
}else{
if ($i % 5 == 0){
echo "Y";
}else{
echo "O";
}
}
}
?>
$k=2; // for calculating position from backside
for($i=1;$i<=11;$i++) //for row
{
for($j=1;$j<=6;$j++) //column
{
if($j==$i && $i<=6) //logic for printing "Y" till the end of row
echo "Y";
else if($i>6 && $j==($i-$k)) //logic for printing "Y" in reversal order from the end of row
{
echo "Y";
$k+=2;
}
else
echo "O"; // filling rest places with "O"
}
echo"\n"; // jumping to new Row;
}
Hope you can understand it easily.
As you see I use this code to increment photos in a file, one by one :
<?php
for ($i = 1; $i <= $photonumber; $i++) {
if($i < 10){
echo '<div class="photos"><a target="_blank"><img src="../photosfile/' . $nom . '0' . $i . '.jpg"/></a></div>';
}
else
{
echo '<div class="photos"><a target="_blank"><img src="../photosfile/' . $nom . $i . '.jpg"/></a></div>';
}
}
?>
I would like to do the same but with php pages reading them from a specific directory like : ../phppages/
Any idea?
I tried but I missed something I guess and I would like to do it same way but with .php instead of .jpg.
Thank you very much.
Try this:
<?php
for ($i = $photonumber; $i >= 1; $i--) {
if($i < 10){
$i = "0".$i;
}
include("../phppages/page".$i.".php");
}
?>
Update: output by 3
<?php
$photonumber = 12;
for ($i = 0; $i < $photonumber; $i++) {
$j = $photonumber - $i;
if($j < 10){
$j = "0".$j;
}
if ($i % 3 === 0)
{
if ($i !== 0)
{
echo '</div>';
}
echo '<div>';
}
include("../phppages/page". $j.".php");
}
echo '</div>';
Update 2
To find the amount of files, that look like "page".$j.".php" in "../phppages" directory try this:
$files = glob("../phppages/page*.php");
$photonumber = count($files);
That would just be this:
for ($i = 1; $i <= $photonumber; $i++) {
include ('php-file-' . $i . '.php');
}
About having it 3 by 3, to be more precise, i want to create a fore each 3 .php file. Like
<?php
for ($i = 1; $i <= $photonumber; $i++) {
if($i < 10){
echo '<div>';
include("../phppages/page".$i.".php") x3;
echo '</div>';
}
?>
Then it become something like this :
div : 12.php + 11.php + 10.php , div : 09.php + 08.php + 07.php , div
:
06.php + 05.php + 04.php , div : 03.php + 02.php + 01.php
Draw a staircase of height N like this:
#
##
###
####
#####
######
Staircase of height 6, note the last line should have zero spaces.
My solution does not work correctly
function draw($size)
{
for ($i = 1; $i <=$size ; $i++)
{
$spaces = $size-$i;
while ($spaces)
{
echo " ";
$spaces--;
}
$stairs = 0;
while ($stairs < $i)
{
echo "#";
$stairs++;
}
echo "<br/>";
}
}
draw(6);
//output
#

It is not printing the spaces, I tried \n, PHP.EOL still it didn't work. Any suggestions?
Although other solutions are all good , here is my code as well.
$max=5;
for ( $i =1 ; $i<=$max;$i++) {
for ( $space = 1; $space <= ($max-$i);$space++) {
echo " ";
}
for ( $hash = 1; $hash <= $i;$hash ++ ) {
echo "#";
}
echo "\n";
}
//PHP
$n = 6; // Number of rows.
for($i=1;$i<=$n;$i++){
echo str_repeat(' ', $n-$i) . str_repeat('#', $i);
echo '\n';
}
for(var i = 0; i < n; i++)
{
var s = "";
for(var j = 0; j < n; j++)
{
if(n - i - 2 < j)
{
s += "#";
}
else
{
s += " ";
}
}
console.log(s);
}
for ($i=0; $i<$n; $i++){
for ($j=0; $j<$n; $j++){
if($i+$j>$n-2){
echo "#";
} else {
echo " ";
}
if($j==$n-1 && $i+$j<$n*2-2){ //The second part is to dont break the last line
echo "\n";
}
}
}
Here's another solution:
$int = 7;
for($i = 1; $i<=$int; $i++){
printf('%1$s%2$s%3$s',str_repeat(" ",$int-$i),str_repeat("#",$i),"\n");
}
From official PHP documentation:
str_repeat
$n = 6;
for ($i = 0; $i < $n; $i++) {
$pad = 1;
for ($space = 0; $space < $n-$i-1; $space++) {
$pad++;
}
echo str_pad('#', $pad,' ',STR_PAD_LEFT);
for ($j = 0; $j < $i; $j++) {
echo '#';
}
echo '<br>';
}
Took me a while but finally I manage to do it following OFC (A. Sharma) Example.
<?php
$handle = fopen("php://stdin","r");
$n = intval(fgets($handle));
for ($rows = 0; $rows < $n; $rows++) {
for ($columns = 0; $columns < $n - $rows - 1; $columns++) {
echo " ";
}
for ($columns = 0; $columns < $rows + 1; $columns++) {
echo "#";
}
echo "\n";
}
?>
Use PHP functions range() and str_repeat() for an elegant solution:
function staircase($n){
foreach (range(1, $n) as $i)
print( str_repeat(' ',$n-$i).str_repeat('#',$i)."\n");
}
demo
Check if n is between 0 and 101 ( 0 < n <= 100)
Loop through each row
2.1 print spaces according to the last item position
2.2 print the items
Separate rows
The code below explains everything...
function staircase($n) {
// check if n is between 0 and 101 (0 < n <=100)
if( 0 < $n && $n > 100 ) {
} else {
// Loop through each row
for($i = 1; $i <= $n; $i++) {
// print spaces according to the last item position
$si = 1;
while( $si <= ($n - $i)){
print(" ");
$si++;
}
// print the items
for($j = 1; $j <= $i; $j++) {
print("#");
}
// separate rows
print("\n");
}
}
}
Output: For n = 6

After playing around with the code and trying/failing couple of times I finally got it right. Notice how in order to print the space and new line I am using "\n". Previous "<br/>" and " " for space didn't work.
Break line will come out of the loop every row number. So if we have $n=4 then every 4 spaces after break line will be echoed.
I have made 2 loops to fill in all fields in the staircase.
The tricky part here is to have them right aligned. This is where if statement comes in place.

Hackerrank Challenge
// Complete the staircase function below.
function staircase($n) {
for($i=1; $i<=$n; $i++){
for($j=1; $j <= $n; $j++){
if( ($n - $i) < $j ){
echo "#";
}else{
echo " ";
}
}
echo "\n";
}
}
Try This
$n=6;
for($i=1;$i<=$n;$i++){
for($spaces=1;$spaces<=($n-$i);$spaces++){
echo " ";
}
for($staires=0;$staires<$i;$staires++){
echo "#";
}
echo "\n";
}
This worked for me
$n = 6;
function staircase($n) {
for($i=1; $i <= $n; $i++){
for($j=1; $j <= $n; $j++){
if($j > $n-$i){
echo "#";
}else{
echo " ";
}
}
echo "\n";
}
}
Use print(' '), if you want to go to next line put print(' ')."\n"
JavaScript:
Solution:
function StairCase(n){
let x = [];
for(let i = 0; i<n; i++){
while(x.length < n){
x.push(" ");
}
x.shift();
x.push("#");
console.log(x.join(''));
} } //StairCase(6)
Hi im looking for a way to breakout of a loop every 3 increments to echo a static string.this script echos a "test" after each increment. i want a test after each 3rd increment. any ideas ?
my loop:
<?php
$i = 0;
while (++$i < 100){
$x = $i - 3;
if ($i+3) {echo $i . "<br>TEST<br>";}
else{ echo $i . "<br>";}
}
?>
try below Code
<?php
for($i=1;$i<=100;$i++)
{
if($i%3==0)
{
echo $i."test"."<br>";
}
}
?>
use % operator in if loop,
i = 0;
while (++$i < 100){
$x = $i - 3;
if ($i%3 == 0) {echo $i . "<br>TEST<br>";}
else{ echo $i . "<br>";}
}
i am facing a problem
can some one suggest me
for ($i = 1; $i <= 2; $i++) {
$r2 = 0;
for ($t = 1; $t <= 2; $t++) {
echo $r2;
$r2++
}
}
output is 0101;
can i get output 0123 ??? please
if
for ($i = 1; $i <= 3; $i++) {
$r2 = 0;
for ($t = 1; $t <= 3; $t++) {
echo $r2;
$r2++
}
}
output is 010101;
can output 012345678 ??? please
and if
for ($i = 1; $i <= 4; $i++) {
$r2 = 0;
for ($t = 1; $t <= 4; $t++) {
echo $r2;
$r2++
}
}
output is 01010101;
can output 0123456789101112131415 ??? please
i think you understand
thanks
In all of these cases you are initializing $r2=0; in the inner loop. It should be outside the loop.
$r2=0;
for($i=1;$i<=2;$i++){
for($t=1;$t<=2;$t++){
echo $r2;
$r2++
}
}
This would produce "1234".
why are you using two nested for loops ?
why not just use one:
for ($i=0; $i<=15; $i++) echo $i . " ";
Try this:
$r2 = 10;
for($t = 0; $t <= $r2; $t++){
echo $r2;
}
Oh wait.. I get it now, why you have the two nested loops, you want to essentially raise a number to the power of 2 in order to control the number of values output. In that case, what you want is simply this:
// this is the variable you need to change to affect the number of values outputed
$n = 2;
// Square $n
$m = $n * $n;
// Loop $m times
for ($i = 0; $i < $m; $i++) {
echo $i;
}
