Iterate through Nested array in PHP - php

I have a nested array on this link Array Sample
I am using code below to parse this, but second and beyond depth it's returning nothing. However tried with recursive function.
printAllValues($ArrXML);
function printAllValues($arr) {
$keys = array_keys($arr);
for($i = 0; $i < count($arr); $i++) {
echo $keys[$i] . "$i.{<br>";
foreach($arr[$keys[$i]] as $key => $value) {
if(is_array($value))
{
printAllValues($value);
}
else
{
echo $key . " : " . $value . "<br>";
}
}
echo "}<br>";
}
}
What I am doing Wrong? Please help.


Version of J. Litvak's answer that works with SimpleXMLElement objects.
function show($array) {
foreach ($array as $key => $value) {
if (!empty($value->children())) {
show($value);
} else {
echo 'key=' . $key . ' value=' . $value. "<br>";
}
}
}
show($ArrXML);


You can use recurcive function to print all values:
function show($array) {
foreach( $array as $key => $value) {
if (is_array($value)) {
show($value);
} else{
echo 'key=' . $key . ' value=' . $value. "<br>";
}
}
}
show($ArrXML);

How to detect URL redirections and separate each header?

I have a problem: i want to detect all redirections of a 3xx response code and separate each header of URL. I investigated that get_headers function follows redirections and put it in an array of each component of redirection. I know that "fb.com" redirects 3 times as you can see on this page:
I want to do the same thing of that page, and am trying to do so:
But my PHP code seems to be wrong. Here it is:
<?php
$header = array();
$header[] = array();
$header_url = #get_headers('http://fb.com',1);
/*
foreach ($header_url as $key => $value){
echo $key . " = " . $value . "<br />";
}
*/
$a = 0;
foreach($header_url as $key => $value){
if(is_int($key)){
$header[$a][] = $value;
$a++;
} else if(!is_int($key) && !is_object($key)){
$header[0][$key] = $value;
} else if(!is_int($key) && is_object($key)){
foreach ($key as $key2 => $value2){
$header[$key2][$key] = $value2;
}
}
}
echo "<h1>ONE</h1>";
foreach ($header[0] as $key => $value) {
echo $key . " = " . $value . "<br />";
}
echo "<h1>TWO</h1>";
foreach ($header[1] as $key => $value) {
echo $key . " = " . $value . "<br />";
}
echo "<h1>THREE</h1>";
foreach ($header[2] as $key => $value) {
echo $key . " = " . $value . "<br />";
}
?>
I would appreciate help on what i am doing wrong.
THANKS SO MUCH AND HAVE A NICE DAY DEV!

How to Print multilevel array index in php

I have the following array:
$array=array("string",array(1,2,3),true,"php");
and I want to print indexes like:
0=>string
1.0=>1
1.1=>2
1.2=>3
2=>true
3=>php

<?php
$array=array("string",array(1,2,3),true,"php");
foreach($array as $key=>$value)
{
if(is_array($value))
{
foreach($value as $childkey=>$childvalue)
{
echo $key . "." . $childkey . "=>" . $childvalue . "\n";
}
}
elseif(is_bool($value))
{
echo $key . "=>" . ($value ? "true" : "false") . "\n";
}
else
{
echo $key . "=>" . $value . "\n";
}
}
Output:
0=>string
1.0=>1
1.1=>2
1.2=>3
2=>true
3=>php

Try this
<?php
$array=array("string",array(1,2,3),true,"php");
foreach($array as $key=>$value){
if(is_array($value)){
foreach($value as $key1=>$value1){
echo $key.".".$key1." => ".$value1."</br>";
}
}
else{
echo $key." => ".$value."</br>";
}
}

<?php
$array=array("string",array(1,2,3),"true","php");
foreach($array as $key=>$value){
if(is_array($value)){
foreach($value as $key1=>$loop){
echo $key.'.'.$key1 .'=>'.$loop."<br>";
}
}else{
echo $key .'=>'.$value."<br>";
}
}
?>

Try this code
$array=array("string",array(1,2,3),true,"php");
foreach($array as $key=>$val){
if(is_array($val)){
foreach($val as $key1=>$val1){
echo $key.'.'.$key1 .'=>'.$val1.'<br/>';
}
}else{
echo $key .'=>'.$val.'<br/>';
}
}

You can try this-
<?php
$arr=array("string",array(1,2,3),true,"php");
$res=convArray($arr);
foreach($res as $k=>$v){
echo $k."=>".$v."\n";
}
function convArray($arr)
{
foreach($arr as $k1=>$v1){
if(is_array($v1)){
foreach($v1 as $k2=>$v2){
$res[$k1.'.'.$k2]=$v2;
}
}else{
$res[$k1]=$v1;
}
}
return $res;
}
?>

Try this:
<?php
$array=array("string",array(1,2,3,array('a','b','c')),true,"php");
$kt = array();
function showarray($arr,$k) {
global $kt;
foreach($arr as $key => $v) {
$nk = $k == '' ? $key:$k.'.'.$key;
if(is_array($v)) {
showarray($v,$nk);
} else {
$kt[$nk] = $v;
}
}
}
showarray($array,"");
print_r($kt);

Php foreach in_array keeps returning false

I built a foreach which loops through a specific folder and gets an array:
foreach ($watchFolder as $key => $value) {
echo '<pre>';
print_r($value);
echo '</pre>';
if((in_array('xml', $watchFolder))) {
echo "true";
} else {
echo "false";
}
foreach ($value as $key => $valueSub) {
$currentWatchPath2 = $currentWatchPath . '\\' . $key;
foreach ($valueSub as $content) {
$currentWatchPath3 = $currentWatchPath2 . '\\' . $content;
}
}
}
If I print out the $watchfolder I get this:
Array (
[test] => Array([videos] => Array()
[xml] => Array())
[test2] => Array([json] => Array([0] => test.json)
[videos] => Array())
)
If I try this:
dd(in_array('xml', $value));
it returns null, whereas it should return true or?
I am really confused at the moment, so I appreciate every tips and suggestion.

xml is a key of $value array so I think you should check like this:
foreach ($watchFolder as $key => $value) {
echo '<pre>';
print_r($value);
echo '</pre>';
if(isset($value['xml'])) { // <--- here is the changed.
echo "true";
} else {
echo "false";
}
foreach ($value as $key => $valueSub) {
$currentWatchPath2 = $currentWatchPath . '\\' . $key;
foreach ($valueSub as $content) {
$currentWatchPath3 = $currentWatchPath2 . '\\' . $content;
}
}
}

In replace of in_array('xml', $watchFolder), it would be used in_array('xml', $value)
foreach ($watchFolder as $key => $value) {
echo '<pre>';
print_r($value);
echo '</pre>';
if((in_array('xml', $value))) {
echo "true";
} else {
echo "false";
}
foreach ($value as $key => $valueSub) {
$currentWatchPath2 = $currentWatchPath . '\\' . $key;
foreach ($valueSub as $content) {
$currentWatchPath3 = $currentWatchPath2 . '\\' . $content;
}
}
}

XML - Nodes with the same name showing only one time in PHP

I have a little problem with decoding my xml with php:
I have an xml file with details about movies, what I need to do is to take the nodes torrents->torrent->quality and show the result in my php script. Right now I have a part of the code, it shows me only the first quality that it finds.
(For example: I have the movie "Poltergeist" that is in 720p and 1080p, but in my script it will only show the 720p and skip the 1080p)
Screenshot website:
Screenshot xml:
<link rel="stylesheet" type="text/css" href="css/style.css">
<?php
$xml = simplexml_load_file("https://yts.to/api/v2/list_movies.xml?limit=10");
$titolo = array();
$locandina = array();
$anno = array();
$durata = array();
$genere = array();
$qualita = array();
$i = 0;
foreach ($xml->data->movies->movie as $element) {
foreach ($element->children() as $key => $val) {
$chiave = $key;
$valore = $val;
if ($key == "title") {
$titolo[] = $val;
}
if ($key == "medium_cover_image") {
$locandina[] = $val;
}
if ($key == "year") {
$anno[] = $val;
}
if ($key == "runtime") {
$durata[] = $val;
}
if ($key == "genres") {
for($g = 0; $g < count($xml->data->movies->movie[$i]->genres->genre); $g++) {
$genere[$i][] = $xml->data->movies->movie[$i]->genres->genre[$g];
}
}
$qualdef = $xml->data->movies->movie->torrents->torrent;
foreach ($qualdef as $element) {
foreach ($element->children() as $key => $val) {
if ($key == "quality") {
$qualita[] = $val;
}
}
}
}
$i++;
}
for ($i = 0; $i < count($titolo); $i++) {
echo "<div class=totbox>";
if (isset($locandina[$i])) {
echo "<div class=box><img src=" . $locandina[$i] . "></div>";
}
echo "<div class=text><b>" . $titolo[$i] . "</b> - " . $anno[$i] . "</div>";
foreach ($genere[$i] as $genResult) {
echo "<div class=text><b>" . $genResult . "</b></div>";
}
echo "<div class=text><b> Qualita':" . $qualita[$i] . "</b></div>";
echo "<div class=text><b> Durata:" . $durata[$i] . "</b></div>";
echo "</div>";
}
?>
What am I doing wrong?

It seems like you are collecting data without any problem but when you are displaying you go by the index of $titolo so you don't go through every element of $qualita array.
So just try this:
echo "<div class=text><b> Qualita':" . implode(', ',$qualita) . "</b></div>";

XML: Show two child nodes with the same name in php

I have a problem with showing my xml into a php page. I have an xml that looks like this (obviously its only a part of it because it really to long to post it all).
It all goes well until it cames to the "genre", I have two values for it and I don't know how to show them at the same time.
<movie>
<id>4441</id>
<title>Rudderless</title>
<title_long>Rudderless (2014)</title_long>
<year>2014</year>
<rating>7.5</rating>
<runtime>105</runtime>
<genres>
<genre>Comedy</genre>
<genre>Drama</genre>
</genres>
</movie>
(an important thing to notice is that not every movie will have two genre, sometimes there is only one and sometime two or three)
This is my code right now
$genere = array();
foreach ($xml->data->movies->movie->genres as $row) {
foreach ($row->children() as $key => $val) {
if ($key == "genre") {
$genere[] = $val;
}
}
}
//and then I'll print
for ($i = 0; $i < 20 ; $i++) {
echo "<div class=text><b>" . $genere[$i] . "</b></div>";
}
When I'm doing this it will print only for the first item of the array, and the others just give me a "Notice: Undefined offset: 1 in /path/ on line 53"
I've tried to follow some guides but it was a failure
What am I doing wrong?
/--Edit--/
<?php
$xml = simplexml_load_file("https://yts.to/api/v2/list_movies.xml")
$titolo = array();
$locandina = array();
$anno = array();

$genere = array();
foreach ($xml->data->movies->movie as $element)
{
foreach($element->children() as $key => $val)
{
$chiave = $key;
$valore = $val;
if ($key == "title")
{
$titolo[] = $val ;
}
if ($key == "medium_cover_image")

echo "<div class=text><b> Durata:" . $durata[$i] . "</b></div>";
echo "</div>";
}
?>

UPDATED - Code fixed. Please, try now.
<?php
$xml = simplexml_load_file("https://yts.to/api/v2/list_movies.xml")
$titolo = array();
$locandina = array();
$anno = array();
$durata = array();
$genere = array();
$i = 0;
foreach ($xml->data->movies->movie as $element) {
foreach ($element->children() as $key => $val) {
$chiave = $key;
$valore = $val;
if ($key == "title") {
$titolo[] = $val;
}
if ($key == "medium_cover_image") {
$locandina[] = $val;
}
if ($key == "year") {
$anno[] = $val;
}
if ($key == "runtime") {
$durata[] = $val;
}
if ($key == "genres") {
for($g = 0; $g < count($xml->data->movies->movie[$i]->genres->genre); $g++) {
$genere[$i][] = $xml->data->movies->movie[$i]->genres->genre[$g];
}
}
}
$i++;
}
for ($i = 0; $i < count($titolo); $i++) {
echo "<div class=totbox>";
if (isset($locandina[$i])) {
echo "<div class=box><img src=" . $locandina[$i] . "></div>";
}
echo "<div class=text><b>" . $titolo[$i] . "</b> - " . $anno[$i] . "</div>";
foreach ($genere[$i] as $genResult) {
echo "<div class=text><b>" . $genResult . "</b></div>";
}
echo "<div class=text><b> Durata:" . $durata[$i] . "</b></div>";
echo "</div>";
}
I hope this helps!

Look on my code, based on yours. PHP file:
<?php
$xml = new SimpleXMLElement(file_get_contents('test.xml'));
$genere = array();
foreach ($xml->genres as $row) {
foreach ($row->children() as $key => $val) {
if ($key == "genre") {
$genere[] = $val;
}
}
}
//and then I'll print
foreach ($genere as $genre) {
echo "<div class=text><b>" . $genre . "</b></div>";
}
XML file:
<movie>
<id>4441</id>
<title>Rudderless</title>
<title_long>Rudderless (2014)</title_long>
<year>2014</year>
<rating>7.5</rating>
<runtime>105</runtime>
<genres>
<genre>Comedy</genre>
<genre>Drama</genre>
</genres>
</movie>
Its work fine, test it.
Based on your full xml file, look on this:
<genres>
<genre>Horror</genre>
</genres>
You have only one genre on first position, so its work fine. You need to loop on movie tag first, not genres. So put your genre tag inside movie foreach.
Like:
foreach($element->children() as $key => $val)
{
if ($key == "genres")
{
// your loop, based on $val variable!
}
