Now the output of the images is carried out using a counter in 3 intervals:
0-73
73-88
88-141
Question: How to remove image output using a counter in the range 0-73?
$name = glob('./album/*.{php}', GLOB_BRACE);
$counter = 0; //заводим счетчик
for($i=0; $i<=(sizeof($name)-1); $i++) {
if( substr($name[$i][2],0,1) != "_") {
echo "<li><img src='".$dir."img/_share/".$shortname."_1.jpg' height='162px'></li>";
$counter++;
if ($counter == 73) {
echo "<li><img src='".$dir."img/_share/".$shortname."_1.jpg' height='162px'></li>";
} elseif ($counter == 88) {
require_once "ddd.php";
} elseif ($counter == 141) {
break;
}
}
}
You need to change == comparison operator to > otherwise it will only execute when $counter is 73. Make sure to remove the extra code that displays the image throughout the loop.
$name = glob('./album/*.{php}', GLOB_BRACE);
$counter = 0; //заводим счетчик
for($i=0; $i<=(sizeof($name)-1); $i++) {
if( substr($name[$i][2],0,1) != "_") {
//echo "<li><img src='".$dir."img/_share/".$shortname."_1.jpg' height='162px'></li>";
$counter++;
if ($counter > 73 && $counter <= 88) {
echo "<li><img src='".$dir."img/_share/".$shortname."_1.jpg' height='162px'></li>";
} elseif ($counter > 88 && $counter <= 141) {
require_once "ddd.php";
} elseif ($counter > 141) {
break;
}
}
}

I have a strange problem with my navigation next/previous code. Everything works fine but random after I click on the next page, the whole navigation is gone. And when I change the pagina variable from page 4 to 5 for example, does everything work again, but pagina 4 keeps removing the navigation. I don't know why it occurs?
On the top of my page do I have:
if (isset($_GET['pagina']) && $_GET['pagina']!="") {
$page_no = $_GET['pagina'];
}
else {
$page_no = 1;
}
$total_records_per_page = 100;
$offset = ($page_no-1) * $total_records_per_page;
$previous_page = $page_no - 1;
$next_page = $page_no + 1;
$adjacents = "2";
And on the bottom of my page
$taal = htmlspecialchars(addslashes($_GET['taal']));
if($page_no > 1){
echo <a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$previous_page."'>Vorige</a>";
}
if ($total_no_of_pages <= 10){
for ($counter = 1; $counter <= $total_no_of_pages; $counter++){
if ($counter == $page_no) {
echo "<a class='active'>".$counter."</a>";
}
else
{
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$counter."'>".$counter."</a>";
}
}
}
elseif ($total_no_of_pages > 10){
if($page_no <= 4) {
for ($counter = 1; $counter < 8; $counter++){
if ($counter == $page_no) {
echo "<span class='active'><a>".$counter."</a></span>";
}
else {
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$counter."'>".$counter."</a>";
}
}
echo "<a>...</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$second_last."'>".$second_last."</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$total_no_of_pages."'>".$total_no_of_pages."</a>";
}
elseif($page_no > 4 && $page_no < $total_no_of_pages - 4) {
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=1'>1</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=2'>2</a>";
//echo "<li><a>...</a></li>";
for (
$counter = $page_no - $adjacents;
$counter <= $page_no + $adjacents;
$counter++
) {
if ($counter == $page_no) {
echo "<span class='active'><a>".$counter."</a></span>";
}else{
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$counter."'>".$counter."</a>";
}
}
echo "<a>...</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$second_last."'>".$second_last."</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$total_no_of_pages."'>".$total_no_of_pages."</a>";
}
else {
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=1'>1</a>";
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=2'>2</a>";
echo "<a>...</a>";
for (
$counter = $total_no_of_pages - 6;
$counter <= $total_no_of_pages;
$counter++
)
{
if ($counter == $page_no) {
echo "<span class='active'><a>".$counter."</a></span>";
}
else{
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$counter."'>".$counter."</a>";
}
}
}
}
if($page_no < $total_no_of_pages) {
echo "<a href='".$page."&taal=".$taal."&zoekveld=".$zoekveld."&pagina=".$next_page."'>Volgende</a>";
}
$taal is language,
$page_no is which page where I'm on
$zoekveld is search field to search on
$pagina is pagenumber in url
I think it has something to do with my GET search field (Zoekveld) but why occurs it after a couple of pages?
Thanks in advance
Help me, i was writing my code, all done succesfully but my problem is when the "..." (separator) for my curerent page and last page showed after the last page, not between my current page and my last page
how can that possible ?
this is my script for showing the page :
<?php
$paging2 = mysqli_query($koneksi,"select * from laporan where seksi='{$seksi}'");
$jmldata = mysqli_num_rows($paging2);
$jmlhalaman = ceil($jmldata/$batas);
echo "<ul class='pagination'>";
if ($halaman !== 1){
echo "<li><a href='index.php?load=table_laporan&halaman=1'>First</a></li>";
}
if ($halaman > 1){
echo "<li><a href='index.php?load=table_laporan&halaman=".($halaman-1)."'>Previous</a></li>";
}
for($i =1; $i <= $jmlhalaman; $i++){
if ((($i >= $halaman - 3) && ($i <= $halaman + 3)) || ($i == 1) || ($i ==$jmlhalaman))
{
if ($i == $halaman){
$class="active";
} else{
$class="disable";
} //echo "<b>$i</b>";
echo "<li class='$class'>".$i."<span class='sr-only'>(current)</span></li>";
if($i==$jmlhalaman && $halaman <= $jmlhalaman-5) echo "<li><a>...</a></li>";
if($i==1 && $halaman >= 6) echo "<li><a>...</a></li>";
}
}
if ($halaman >= 1){
echo "<li><a href=index.php?load=table_laporan&halaman=". ($halaman+1)."'>Next</a></li>";
} if ($halaman >= 1){
echo "<li><a href='index.php?load=table_laporan&halaman=". ($jmlhalaman)."'>Last</a></li>";
}
echo "</ul>";
echo "<p>Total Data : <b>$jmldata</b> Data</p>";
?>
I'm having trouble making a simple count work. Right now 0 is constantly displayed when I run the code and I know it's because I set count to 0. But it should be displaying the number of times "Fizz" is displayed.
I'm sure it's simple but I just can't see what!
public function __construct($firstParam, $secondParam, $firstSound = "Fizz", $secondSound = "Buzz", $numbers = 100) {
$this->firstParam = $firstParam;
$this->secondParam = $secondParam;
$this->firstSound = $firstSound;
$this->secondSound = $secondSound;
$this->numbers = $numbers;
$this->numsArray = $numsArray;
}
public function __toString() {
$count = 0;
for ($i = 0; $i < count($this->numsArray); $i++){
$val = $this->numsArray[$i];
if ($val == $this->firstSound) {
$count++;
}
}
$print = "Number of Fizzes: ".$count;
return $print;
}
public function execute() {
$this->numsArray = array();
if ($this->secondParam > $this->firstParam) {
for ($i = 1; $i <= $this->numbers; $i++){
if ($i % $this->firstParam == 0 && $i % $this->secondParam == 0) {
$this->numsArray[] = "\n".$this->firstSound.$this->secondSound."\n";
} elseif ($i % $this->firstParam == 0) {
$this->numsArray[] = "\n".$this->firstSound."\n";
} elseif ($i % $this->secondParam == 0) {
$this->numsArray[] = "\n".$this->secondSound."\n";
} else {
$this->numsArray[] = "\n".$i."\n";
}
echo $this->numsArray[$i-1];
}
} else {
echo "\n".' First Number Bigger Than Second '."\n";
}
}
In your execute you are not assigning the values to numsArray[i] also you inject new line characters that will not match the equality you just when checking $val. Also I notice you use zero index to check them and index 1 to load it. Change execute to:
for ($i = 0; $i < $this->numbers; $i++){
if ($i % $this->firstParam == 0 && $i % $this->secondParam == 0) {
$this->numsArray[i] = $this->firstSound.$this->secondSound;
} elseif ($i % $this->firstParam == 0) {
$this->numsArray[i] = $this->firstSound;
} elseif ($i % $this->secondParam == 0) {
$this->numsArray[i] = $this->secondSound;
} else {
$this->numsArray[i] = $i;
}
echo $this->numsArray[$i];
This is a better binary string comparison for php...
if (strcmp($val, $this->firstSound) == 0)
I have an issue where I don't know for a foreach() loop to change the output on every(x) amount of results.
Here is my foreach() code:
$dir_handle = 'assets/icons/';
foreach(array_diff(scandir($dir_handle), array('.', '..')) as $file) {
$cut = substr($file, -4);
echo '<img id="preload_header" src="assets/icons/' . $file . '" /><br />';
}
How would I get it for that 1-4 have the same result, but then 5-8 have a different result, and then back to 1-4?
You want to do a count in your foreach loop
$count = 1;
foreach(array_diff(scandir($dir_handle), array('.', '..')) as $file) {
//Check if count is between 1 and 4
if($count >= 1 && $count <= 4) {
//Do something
} else { //Otherwise it must be between 5 and 8
//Do something else
//If we are at 8 go back to one otherwise just increase the count by 1
if($count == 8) {
$count = 1;
} else {
$count++;
}
}
}
You can use the % operator, combined with a division by 4:
foreach ($a as $key => $val) {
$phase = $key / 4 % 2;
if ($phase === 0) {
echo 'here';
}
elseif ($phase === 1) {
echo 'there';
}
}
This switches between the two branches every 4 iterations of your loop.
As pointed out in the comments, the above method assumes that the keys of your array are in order. If not, you can add a counter variable in the loop, like:
$c = 0;
foreach ($a as $val) {
$phase = $c++ / 4 % 2;
if ($phase === 0) {
echo 'here';
}
elseif ($phase === 1) {
echo 'there';
}
}
here is the problem, i need to find prime numbers up to a certain number and here is my code:
$a = 56;
for($i = 2; $i<=$a; $i++)
{
if($i == 2)
{
echo "2</br>";
}
if($i == 3)
{
echo "3</br>";
}
if($i == 5)
{
echo "5</br>";
}
if($i == 7)
{
echo "7</br>";
}
for($j =3; $j <= ceil($i/2); $j = $j + 2)
{
if($i % 2 == 0)
{
break;
}
if($i % 3 == 0)
{
break;
}
if($i % 5 == 0)
{
break;
}
if($i % 7 == 0)
{
break;
}
else
{
echo "$i</br>";
break;
}
}
}
It works fine, but it kinda seems like a brute force algorithm, doesnt it? Is there any other way to do this?
Thanks for help!!!
Suppose x is the limit (till which you want prime number)..
for($n=2;$n<=$x;$n++)
{
$i=2;
while($i<=$n-1)
{
if($n % $i == 0)
break;
$i++;
}
if($i==$num)
echo $n; // $n is the prime number...
}
