Text after last sibling in DOM is not showing - php

i have this code which replace [img] tag with its source, but text after last image tag is not showing in the output
$url = 'aa<img class="emojioneemoji" src="http://localhost/sng/assets/js/plugins/em/2.1.4/assets/png/1f62c.png">bb<img class="emojioneemoji" src="http://localhost/sng/assets/js/plugins/em/2.1.4/assets/png/1f600.png">cc';
$doc = new DOMDocument();
#$doc->loadHTML($url);
$tags = $doc->getElementsByTagName('img');
$str = "" ;
foreach ($tags as $tag) {
$img_path = $tag->getAttribute('src');
$directory = $img_path;
$ee = pathinfo($directory);
$pic_name= $ee['basename'];
$next = "" ;
$previous = "";
//echo $tag->nextSibling->wholeText;
if ($tag->previousSibling && get_class($tag->previousSibling) == "DOMText") {
$previous = $tag->previousSibling->wholeText . "-" ;
}
elseif($tag->nextSibling && get_class($tag->nextSibling) == "DOMText") {
$next = $tag->nextSibling->wholeText . "-" ;
}
$str .= $previous. $pic_name . "-" . $next ;
}
echo $str ;
output of above is
aa-1f62c.png-bb-1f600.png-
how can i get text 'cc' after last [img] tag. ?

There are logic errors in you if-else statements. Try the following code:
<?php
$url = 'aa<img class="emojioneemoji" src="http://localhost/sng/assets/js/plugins/em/2.1.4/assets/png/1f62c.png">bb<img class="emojioneemoji" src="http://localhost/sng/assets/js/plugins/em/2.1.4/assets/png/1f600.png">cc';
$doc = new DOMDocument();
#$doc->loadHTML($url);
$tags = $doc->getElementsByTagName('img');
$str = "" ;
$i=0;
$src_array=array();
foreach ($tags as $tag) {
$img_path = $tag->getAttribute('src');
$src_array[]=$img_path;
$directory = $img_path;
$ee = pathinfo($directory);
$pic_name= $ee['basename'];
$next = "" ;
$previous = "";
if ($tag->previousSibling && get_class($tag->previousSibling) == "DOMText") {
$previous = $tag->previousSibling->wholeText . "-" ;
}
if($tag->nextSibling && get_class($tag->nextSibling) == "DOMText") {
$next = $tag->nextSibling->wholeText . "-" ;
}
if(isset($previous_tag)){
$previous="";
}
$str .= $previous. $pic_name . "-" . $next ;
$previous_tag=$tag;
}
$str=rtrim($str,"-");
echo $str ;
Updated:
If you want to recover the string, you could try the following code with adding an array $src_array in the code above to store the link src:
echo "<br/>";
$str_array=explode("-",$str); //please pay attention to the splitter character, it should be enough special
$j=0;
$recover_str="";
for($i=0;$i<count($str_array);$i++)
{
if(($i%2)==0){
$recover_str .= $str_array[$i];
}
else{
$recover_str .= '<img class="emojioneemoji" src="'.$src_array[$j].'">';
$j++;
}
}
echo $recover_str ;

I'm trying to convert an array to XML but I am failing to get it 100% correct

I need to output the response from the database in XML. So far I have gotten it to output this:
The outermost tag needs to match the name of the action query, it'll either be <courses> or <students>.
Here is my code:
<?php
require_once('./database.php');
if (isset($_GET['format'])) {
$format = filter_var($_GET['format']);
}
if (isset($_GET['action'])) {
$action = filter_var($_GET['action'], FILTER_SANITIZE_STRING);
$tableName = "sk_$action";
}
$query = "SELECT * FROM $tableName";
if (isset($_GET['course'])) {
$course = filter_input(INPUT_GET, 'course');
$query .= " WHERE courseID = :course";
}
function arrayToXml($arr, $i = 1, $flag = false)
{
$sp = "";
for ($j = 0; $j <= $i; $j++) {
$sp .= " ";
}
foreach ($arr as $key => $val) {
echo "$sp<" . $key . ">";
if ($i == 1) echo "\n";
if (is_array($val)) {
if (!$flag) {
echo "\n";
}
arrayToXml($val, $i + 5);
echo "$sp</" . $key . ">\n";
} else {
echo "$val" . "</" . $key . ">\n";
}
}
}
$statement = $db->prepare($query);
$statement->bindValue(':course', $course);
$statement->execute();
$response = $statement->fetchAll(PDO::FETCH_ASSOC);
$statement->closeCursor();
if ($format == 'json') {
echo json_encode($response);
}
if ($format == 'xml') {
arrayToXml($response, 1, true);
}
I'm pretty new to PHP and have never worked with XML. All help is appreciated. Thanks.
function arrayToXml($arr, $collectionTag, $singleTag) {
$collection = new SimpleXMLElement("<$collectionTag/>");
foreach ($arr as $row) {
$element = $root->addChild($singleTag);
foreach ($row as $tag => $value) {
$element->addChild($tag, $value);
}
}
return $collection;
}
$courses = arrayToXml($response, 'courses', 'course');
echo $courses->asXML();
Tested with PHP 7.1.23. Output:
<?xml version="1.0"?>
<courses>
<course><courseID>cs601</courseID><courseName>Web Application Development</courseName></course>
<course><courseId>cs602</courseId><courseName>Server-Side Application Development</courseName></course>
<course><courseId>cs701</courseId><courseName>Rich Internet Application Development</courseName></course>
</courses>
(I added newlines because by default it doesn't add any.)

cron jobs doesn't work with some php function

when i set some cron jobs for loading a php file cron doesn't work and it seams some php function have problem with cron job.
i know my cron command is true because i tested my cron job working true with simple php code that put date to a text file so my cron command is true i tested all ways of command like : wget, crul , cd, php , /user/local/bin/php and another but i don't know why my php code doesn't work and too i test that codes working very well when i loading php files with my browser.

error in gallery pagination

I've adapted a simple paginated gallery to my needs, but it doesn't work as expected: usually it puts well the first "page" og pictures then in some cases it just skip some pictures and then go to further ones, in other cases it just do not load any other page (I'm using infinitescroll)
here is the php function:
function makeGallery($path, $directory, $seo){
$dir = $path . "/" . $directory;
$handle = opendir($dir);
while ($file = readdir($handle)){
if($file == '.' OR $file == '..' or $file == 'thumbs' or $file == '.DS_Store')
continue;
else
$result_array[]=$file;
}
$filecount = count(glob("" . $dir . "*.jpg"));
closedir($handle);
array_multisort($result_array, SORT_ASC);
$rows = 3;
$cols = 8;
if(isset($_GET['page'])){
$page = $_GET['page'];
}else{
$page = 0;
}
$num_pics = count($result_array);
$cells = $rows * $cols;
$pages = ceil($num_pics / $cells);
$num_pages = $pages - 1;
$output = array();
$slices = array();
$push = 0;
$showpage = $page + 1;
for($k=0;$k<$pages;$k++){
array_push($slices, $push);
$push = $push + $cells;
}
for($k=0;$k<$pages;$k++){
if($page == key($slices)){
$output = array_slice($result_array, current($slices), $cells);
}
next($slices);
}
reset($output);
print '<div class="container-fluid">
<div class="row">';
print "<ul id='photoswipe' class='thumbnails'>";
for($i=0;$i<$rows;$i++){
for($j=0;$j<$cols;$j++){
if(current($output) != false){
$value = current($output);
$parts = Explode('.', $value);
$title = $parts[count($parts) - 2];
$parts = Explode('-', $title);
$title = $parts[1];
if ($title == "") $title = $value;
print "<li class='box'><a title='$title' rel='group' class='thumbnails' href='$dir/$value'><img width='$width' height='inherrit' src='$dir/thumbs/$seo-$value' /></a></li>";
next($output);
}else{
print "</ul>";
}
}
}
$ref = $_SERVER['PHP_SELF'];
if($num_pages == '0'){
print " ";
print " ";
}elseif(($page == '0')||($page == '')){
$next = $page + 1;
print " ";
print "<a id='next' href='$ref?page=$next'> </a>";
}elseif($page == $num_pages){

print "<a id='next' href='$ref?page=$next'> </a>";
}
echo "<nav id='page-nav'>
<a href='$ref?page=$next'></a>
</nav></div></div>";
}
I'm sure there should be some silly bug that i've not spotted and i hope that some experienced php programmer can find it very easily.
you could see the gallery (and its problem) on http://eikonabox.com/page/portrait.php
(in the portrait gallery as you can see it jumps from the number 24 directly to number 49)
Thank you all
If somone get stuck in this kind of problem I've resolved this way:
function makeGallery($path, $directory, $seo){
$dir = $path . "/" . $directory;
$filearray = array();
if ($fil = opendir($dir)) {
while (($file = readdir($fil)) !== false) {
if ($file != "." && $file != ".." && $file != "thumbs" && $file != ".DS_Store") {
$filearray[] = $file;
$page = empty($_GET['page']) ? 1 : $_GET['page'];
$num_per_page = 25;
$total_pages = ceil(count($filearray)/$num_per_page);
}
}
array_multisort($filearray, SORT_ASC);
print '<div class="container-fluid">
<div class="row">';
print "<ul id='photoswipe' class='thumbnails'>";
for($i = ($page - 1) * $num_per_page; $i < $page * $num_per_page; $i++){
$value = basename($filearray[$i]);
$parts = Explode('.', $value);
$title = $parts[count($parts) - 2];
$parts = Explode('-', $title);
$title = $parts[1];
if ($title == "") $title = $value;
if($value != "")
print "<li class='box'><a title='$title' rel='group' class='thumbnails' href='$dir/$value'><img width='$width' height='inherrit' src='$dir/thumbs/$seo-$value' /></a></li>";
}
closedir($fil);
}
print "</ul>";
$ref = $_SERVER['PHP_SELF'];
if($num_pages == '0'){
print " ";
print " ";
}elseif(($page == '0')||($page == '')){
$next = $page + 1;
print " ";
print "<a id='next' href='$ref?page=$next'> </a>";
}elseif($page == $num_pages){

I need help to get work.
The following will display the list of directories, beginning each group with a first letter as beginning of the group (see codepad for proof):
(this assumes $dirs is array containing the names)
$cur_let = null;
foreach ($dirs as $dir) {
if ($cur_let !== strtoupper(substr($dir,0,1))){
$cur_let = strtoupper(substr($dir,0,1));
echo $cur_let."\n";
}
echo $dir . "\n";
}
You just need to add some formatting on your own, suited to your needs.
Edit:
Version grouping under # sign entries that begin with a number, can look like that:
$cur_let = null;
foreach ($dirs as $dir) {
$first_let = (is_numeric(strtoupper(substr($dir,0,1))) ? '#' : strtoupper(substr($dir,0,1)));
if ($cur_let !== $first_let){
$cur_let = $first_let;
echo $cur_let."\n";
}
echo $dir . "\n";
}
Please see codepad as a proof.
Is this what you are looking for?
<?php
$places = array(
'Aberdeen',
'Arundel',
'Aberyswith',
'Bath',
'Bristol',
'Brighton',
'Cardiff',
'coventry'
);
$first_letter = $places[0][0];
foreach($places as $p)
{
if(strtolower($p[0])!=$first_letter)
{
echo "<b>" . strtoupper($p[0]) . "</b><br/>";
$first_letter = strtolower($p[0]);
}
echo $p . "<br/>";
}
?>
Prints:
A
Aberdeen
Arundel
Aberyswith
B
Bath
Bristol
Brighton
C
Cardiff
coventry
My approach would be to generate a second array that associates the first letter to the array of names that begin with that letter.
$dirs; // assumed this contains your array of names
$groupedDirs = array();
foreach ($dirs as $dir) {
$firstLetter = strtoupper($dir[0]);
$groupedDirs[$firstLetter][] = $dir;
}
Then, you can iterate on $groupedDirs to print out the list.
<?php foreach ($groupedDirs as $group => $dirs): ?>
<?php echo $group; ?>
<?php foreach ($dirs as $dir): ?>
<?php echo $dir; ?>
<?php endforeach; ?>
<?php endforeach; ?>
This allows for a clean separation between two separate tasks: figuring out what the groups are and, secondly, displaying the grouped list. By keeping these tasks separate, not only is the code for each one clearer, but you can reuse either part for different circumstances.
Use something like this, change it to output the HTML the way you want thouugh:
sort($subdirs);
$count = count($subdirs);
$lastLetter = '';
foreach($subdirs as $subdir => $opts){
if(substr($subdir,0,1) !== $lastLetter){
$lastLetter = substr($subdir,0,1);
echo '<br /><div style="font-weight: bold;">'.strtoupper($lastLetter).'</div>';
}
echo '<div>'.$subdir.'</div>';
}
EDIT
Just realized $subdir is associative, made the change above:
