How can I foreach this array object? - php

I want to foreach the game name and info and each game must filter as platform_name.
$list = (object)[];
$list->egame =
[
(object)['platform_name'=>'TT', 'game'=>(object)[(object)['game_name'=>'game1', 'info'=>'test1'],(object)['game_name'=>'game2', 'info'=>'test2'],(object)['game_name'=>'game3', 'info'=>'test3']]],
(object)['platform_name'=>'TG', 'game'=>(object)[(object)['game_name'=>'game4', 'info'=>'test4'],(object)['game_name'=>'game5', 'info'=>'test5']]],
(object)['platform_name'=>'TBIN', 'game'=>(object)[(object)['game_name'=>'game6', 'info'=>'test6']]]
];
?>

Try this
$list = (object)[];
$list->egame =
[
(object)['platform_name' => 'TT', 'game' => (object)[(object)['game_name' => 'game1', 'info' => 'test1'], (object)['game_name' => 'game2', 'info' => 'test2'], (object)['game_name' => 'game3', 'info' => 'test3']]],
(object)['platform_name' => 'TG', 'game' => (object)[(object)['game_name' => 'game4', 'info' => 'test4'], (object)['game_name' => 'game5', 'info' => 'test5']]],
(object)['platform_name' => 'TBIN', 'game' => (object)[(object)['game_name' => 'game6', 'info' => 'test6']]]
];
$arr = (array)$list->egame;
for ($i = 0; $i < count($arr); $i++) {
foreach ($arr[$i] as $key => $value) {
$aa = (array)$arr[$i]->game;
foreach ($aa as $k => $v) {
echo $aa[$k]->game_name." ".$aa[$k]->info."<br/>";
}
echo "<br/>";
}
}

Here You go:
<?php
$list = (object)[];
$list->egame =
[
(object)['platform_name'=>'TT', 'game'=>(object)[(object)['game_name'=>'game1', 'info'=>'test1'],(object)['game_name'=>'game2', 'info'=>'test2'],(object)['game_name'=>'game3', 'info'=>'test3']]],
(object)['platform_name'=>'TG', 'game'=>(object)[(object)['game_name'=>'game4', 'info'=>'test4'],(object)['game_name'=>'game5', 'info'=>'test5']]],
(object)['platform_name'=>'TBIN', 'game'=>(object)[(object)['game_name'=>'game6', 'info'=>'test6']]]
];
foreach ( $list->egame as $eg ) {
foreach ( $eg->game as $game ) {
echo "game: " . $game->game_name . " info: " . $game->info . "<br>";
}
}
?>
Edit #1
Includes platform:
foreach ( $list->egame as $eg ) {
foreach ( $eg->game as $game ) {
echo "platform: " . $eg->platform_name . " game: " . $game->game_name . " info: " . $game->info . "<br>";
}
}

Calculating with multi arrays

I need help with some of my code. I need to use the numbers in prijs for a calculation.
$autos = array(
"<b>Mercedes</b>" =>array(
"Kenteken" => "77NLXJ",
"Prijs" => "54800",
),
"<b>Tesla</b>" =>array(
"Kenteken" => "GV713G",
"Prijs" => "70700",
),
"<b>Porsche</b>" =>array(
"Kenteken" => "GG101K",
"Prijs" => "85000",
)
Is this possible?
$keys = array_keys($autos);
for($i = 0; $i < count($autos); $i++) {
echo $keys[$i] . "<br>";
foreach($autos[$keys[$i]] as $key => $value) {
echo $key . " : " . $value . "<br>";
}
echo "<br>";
}
To access and change them, you need to access them through the $autos array:
//by loop:
foreach($autos as $key => $auto){
//get or set them with this var
$autos[$key]["Prijs"];
}
//to get and set them directly:
$autos[0]["Prijs"];
$autos[1]["Prijs"];
$autos[2]["Prijs"];

How to auto increment in sub foreach loop?

Here is the example code:
<?php
$arr = array(
array(
'company' => array(
'code' => 'ccd1',
'name' => 'cnm1'
) ,
'products' => array(
array(
'code' => 'pcd1',
'name' => 'pnm1'
) ,
array(
'code' => 'pcd2',
'name' => 'pnm2'
)
)
) ,
array(
'company' => array(
'code' => 'ccd2',
'name' => 'cnm2'
) ,
'products' => array(
array(
'code' => 'pcd1',
'name' => 'pnm1'
) ,
array(
'code' => 'pcd2',
'name' => 'pnm2'
) ,
array(
'code' => 'pcd3',
'name' => 'pnm3'
)
)
)
);
echo "<pre>"; print_r($arr); echo "</pre>";
$AI = 1;
foreach($arr as $value){
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
foreach($value['products'] as $value2){
echo " ".$value2['name']."<br />";
}
}
I don't know how to explain it, but what I want is to add auto increment in sub foreach loop, like this:
1.cnm1 (2)
1.pnm1
2.pnm2
2.cnm2 (3)
1.pnm1
2.pnm2
3.pnm3
Usually you can just use the foreach keys plus one. As another alternative, if this is just for presentation, just use ordered lists:
echo '<ol>';
foreach($arr as $ar1) {
echo '<li>' . $ar1['company']['name'] . ' (' . count($ar1['products']) . ')</li>';
echo '<ol>';
foreach($ar1['products'] as $ar2) {
echo "<li>{$ar2['name']}</li>";
}
echo '</ol>';
}
It'll number those items accordingly. No need for addition. Plus you can use CSS to style the list,
You can access the key/index of an foreach :
foreach($arr as $i => $value){
$total_products = count($value['products']);
echo ($i+1).'.'.$value['company']['name'].' ('.$total_products .')<br />';
foreach($value['products'] as $j => $value2){
echo ' '.($j+1).'.'.$value2['name'].'<br />';
}
}
Here you go.
$arr = array(array('company'=>array('code'=>'ccd1', 'name'=>'cnm1'), 'products'=>array(array('code'=>'pcd1', 'name'=>'pnm1'), array('code'=>'pcd2', 'name'=>'pnm2'))), array('company'=>array('code'=>'ccd2', 'name'=>'cnm2'), 'products'=>array(array('code'=>'pcd1', 'name'=>'pnm1'), array('code'=>'pcd2', 'name'=>'pnm2'), array('code'=>'pcd3', 'name'=>'pnm3'))));
echo "<pre>";
print_r($arr);
echo "</pre>";
$AI = 1;
foreach($arr as $value)
{
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
$k = 0;
foreach($value['products'] as $value2)
{
echo " ".$k++.". ".$value2['name']."<br />";
}
}
This also worked for me:
foreach($value['products'] as $key2=>$value2){
$AI2 = $key2+1;
echo " ".$AI2.".{$value2['name']}<br />";
}
You can try this:
foreach($arr as $value){
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
$sub=1;
foreach($value['products'] as $value2){
echo " ".$sub++.'.'.$value2['name']."<br />";
}
}

How Can I Convert a Multidimensional Array in Php to XML

I have an array like
$a = array(
'aaa' => "sample",
'bbb' => "sample2",
'ccc' => "adas",
'ddd' => "2",
'eee' => '2013-09-05',
'fff' => "false",
'ggg' => "893",
'qqq' => '2013-09-05',
'sss' => array(
"iii" => array(
'vvv' => "sample3",
'xxx' => 500,
)
),
'nnn' => '2013-09-05',
'mmm' => "Normal",
);
and I want to convert it to xml but witout using SimpleXMLElement or another function. That's why I have tried to do it with foreach. Here is my code ;
$data = '';
foreach ($a as $k => $v) {
if (is_array($k)) {
$data .= "<a:$k>" . $v . "</a:$k>";
foreach ($k as $j => $m) {
if (is_array($j)) {
foreach ($j as $s => $p) {
$data .= "<a:$s>" . $p . "</a:$s>";
}
} else {
$data .= "<a:$j>" . $m . "</a:$j>";
}
}
} else {
$data .= "<a:$k>" . $v . "</a:$k>";
}
}
but it's not working. I can make it work with hashmaps in another language but it must be in php. How can I do this.
Thanks.
You could try this:
function createXml($array, $level = 0)
{
$xml = ($level == 0) ? '<?xml version="1.0" encoding="ISO-8859-1"?>'.PHP_EOL : '';
$tab = str_pad('', $level, ' ', STR_PAD_LEFT);
foreach($array as $node => $value)
{
$xml .= "{$tab}<{$node}>";
if(!is_array($value))
{
$xml .= $value;
}
else
{
$level++;
$xml .= PHP_EOL.createXml($value, $level).$tab;
}
$xml .= "</{$node}>".PHP_EOL;
}
return $xml;
}
$xml = createXml($a);
echo $xml;

Read nested array dynamicly in php

I need to read nested arrays without knowing how the array will look.
For example;
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
Needs to be formatted to strings like:
Data1_lvl1/Data1_lvl2/
Data1_lvl1/Data2_lvl2/Data1_lvl3/
Data2_lvl1/
But the array can be of any size with any number of nested arrays inside it.
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
function printArray($array)
{
foreach ($array as $key=>$value)
{
echo $key.'/';
if (is_array($value))
{
printArray($value);
} else {
echo '<br>';
}
}
}
printArray($data);
If you want to output only the name of array elements then this recursive function will do the trick.
Your data:
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
Function:
function array2str($array, $str) {
foreach($array as $key => $val) {
if (is_array($val) ) {
$str .= $key . '/';
array2str($val, $str);
}
}
echo $str.'<br />';
return $str;
}
array2str($data);
As you can see the script does ECHO in itself with <br /> to break the line when viewing results in a browser.
One way would to walk recursively through array with function similar to this:
<?php
function f($d, $str = '') {
foreach ($d as $key => $val) {
if (is_array($val)) f($val, $str . '/' . $key); // If this element is array parse next level
else print_r($str . '/' . $key . '/'); // Output current string or do what you need to do with it..
}
}
$data = array(
'Data1_lvl1' => array(
'Data1_lvl2' => "value",
'Data2_lvl2' => array(
'Data1_lvl3' => "value"
)
),
'Data2_lvl1' => 'value'
);
f($data);
with that function:
<?php
function print_tree ($data, $prefix = '', &$index = 1) {
foreach($data as $key => $datum) {
echo $index++ . '. ' . ($new_prefix = $prefix . $key . '/') . PHP_EOL;
if (is_array($datum)) {
print_tree ($datum, $new_prefix, $index);
}
}
}
I get
Data1_lvl1/
Data1_lvl1/Data1_lvl2/
Data1_lvl1/Data2_lvl2/
Data1_lvl1/Data2_lvl2/Data1_lvl3/
Data2_lvl1/

Get array's key recursively and create underscore separated string

Right now i got an array which has some sort of information and i need to create a table from it. e.g.
Student{
[Address]{
[StreetAddress] =>"Some Street"
[StreetName] => "Some Name"
}
[Marks1] => 100
[Marks2] => 50
}
Now I want to create database table like which contain the fields name as :
Student_Address_StreetAddress
Student_Address_StreetName
Student_Marks1
Student_Marks2
It should be recursive so from any depth of array it can create the string in my format.
You can use the RecursiveArrayIterator and the RecursiveIteratorIterator (to iterate over the array recursively) from the Standard PHP Library (SPL) to make this job relatively painless.
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($arr));
$keys = array();
foreach ($iterator as $key => $value) {
// Build long key name based on parent keys
for ($i = $iterator->getDepth() - 1; $i >= 0; $i--) {
$key = $iterator->getSubIterator($i)->key() . '_' . $key;
}
$keys[] = $key;
}
var_export($keys);
The above example outputs something like:
array (
0 => 'Student_Address_StreetAddress',
1 => 'Student_Address_StreetName',
2 => 'Student_Marks1',
3 => 'Student_Marks2',
)
(Working on it, here is the array to save the trouble):
$arr = array
(
'Student' => array
(
'Address' => array
(
'StreetAddress' => 'Some Street',
'StreetName' => 'Some Name',
),
'Marks1' => '100',
'Marks2' => '50',
),
);
Here it is, using a modified version of #polygenelubricants code:
function dfs($array, $parent = null)
{
static $result = array();
if (is_array($array) * count($array) > 0)
{
foreach ($array as $key => $value)
{
dfs($value, $parent . '_' . $key);
}
}
else
{
$result[] = ltrim($parent, '_');
}
return $result;
}
echo '<pre>';
print_r(dfs($arr));
echo '</pre>';
Outputs:
Array
(
[0] => Student_Address_StreetAddress
[1] => Student_Address_StreetName
[2] => Student_Marks1
[3] => Student_Marks2
)
Something like this maybe?
$schema = array(
'Student' => array(
'Address' => array(
'StreetAddresss' => "Some Street",
'StreetName' => "Some Name",
),
'Marks1' => 100,
'Marks2' => 50,
),
);
$result = array();
function walk($value, $key, $memo = "") {
global $result;
if(is_array($value)) {
$memo .= $key . '_';
array_walk($value, 'walk', $memo);
} else {
$result[] = $memo . $key;
}
}
array_walk($schema, 'walk');
var_dump($result);
I know globals are bad, but can't think of anything better now.
Something like this works:
<?php
$arr = array (
'Student' => array (
'Address' => array (
'StreetAddress' => 'Some Street',
'StreetName' => 'Some Name',
),
'Marks1' => array(),
'Marks2' => '50',
),
);
$result = array();
function dfs($data, $prefix = "") {
global $result;
if (is_array($data) && !empty($data)) {
foreach ($data as $key => $value) {
dfs($value, "{$prefix}_{$key}");
}
} else {
$result[substr($prefix, 1)] = $data;
}
}
dfs($arr);
var_dump($result);
?>
This prints:
array(4) {
["Student_Address_StreetAddress"] => string(11) "Some Street"
["Student_Address_StreetName"] => string(9) "Some Name"
["Student_Marks1"] => array(0) {}
["Student_Marks2"] => string(2) "50"
}
function getValues($dataArray,$strKey="")
{
global $arrFinalValues;
if(is_array($dataArray))
{
$currentKey = $strKey;
foreach($dataArray as $key => $val)
{
if(is_array($val) && !empty($val))
{
getValues($val,$currentKey.$key."_");
}
else if(!empty($val))
{
if(!empty($strKey))
$strTmpKey = $strKey.$key;
else
$strTmpKey = $key;
$arrFinalValues[$strTmpKey]=$val;
}
}
}
}
