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"];

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>";
}
}
I would like the data to be echoed out in this format
[0] - [name][description]
[1] - [name][description]
[2] - [name][description]
$options = array('guide_info' => $guide_info);
$guide_info = array( 'guide_name' => $guide_name,
'guide_description' => $guide_description
);
I created two foreach loops to try and echo out the name and description of each, like this:
foreach ($options as $key => $value) {
foreach ($guide_info as $type => $info){
$html .= $type . " " . $info . "\n";
}
}
but I receive errors about invalid argument supplied for foreach() on the second loop.
Currently my print_r($options) shows
Array ( [guide_name] => f
[guide_description] => fff
[0] => Array (
[guide_name] => fsss
[guide_description] => sssss
)
)
and my echo prints
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
How would I be able to echo out the correct information that print_r is showing?
Use a recursive function to echo out the name and description values in the desired format.
function process_array($arr, $counter){
foreach($arr as $key => $value){
if(is_array($value)){
process_array($value, ++$counter);
}else{
if($key == "guide_name"){
echo "[" . $counter . "] - [" . $value . "][";
}else{
echo $value . "]<br />";
}
}
}
}
// Here $options is your original array
process_array($options, 0);
Output:
[0] - [f][fff]
[1] - [fsss][sssss]
$guide_info = array( 'guide_name' => 'guid name',
'guide_description' => 'guid description',
);
$options = array('guide_info' => $guide_info);
foreach ($options as $key => $value) {
foreach($value as $a => $b) {
echo $a," =",$b ;
}
}
or for print_r
foreach ($options as $key => $value) {
print_r($value) ;
}
Why are you putting the $guide_info in $options.If you want all the entries from $guide_info, you can do this-
for($i = 0; $i < count($guide_info); $i++){
$html .= $type . " " . $info . "\n";
}
-> considering $guide_info is a multidimensional array like = array( [0] => 'guide_name' => $guide_name,
'guide_description' => $guide_description)
If for some reason $guide_info IS important, I would suggest it to be an indexed array not assoc.. Hope you find the solution :)
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 />";
}
}
i want to send more than on array in foreach() .
i know this way is false .whats the true method ?
$Fname = [1,2,3,4,5];
$Lname = [1,2,3,4,5];
$Addrs = [1,2,3,4,5];
$Mobile = [1,2,3,4,5];
$fields = array(
'name' => 'a',
'type' => 'b',
'value' => 'n',
'show' => 'd',
);
foreach($fields as $key => $n)
{
echo " {$Fname[$key]} , {$Lname[$key]},{$Addrs[$key]} , {$Mobile[$key]},{$key} ,{$n} <br>";
}
If all your arrays have the same number of rows, you can use a for loop instead of a foreach, in conjunction with next() and current() for associative array:
for( $i = 0; $i < count($Fname); $i++ )
{
echo $Fname[$i] . PHP_EOL;
echo $Lname[$i] . PHP_EOL;
echo $Addrs[$i] . PHP_EOL;
echo $Mobile[$i] . PHP_EOL;
echo current($fields) . PHP_EOL;
next($fields);
}
The problem is that your arrays haven't same rows number...
So you have to add some condition like this:
for( $i = 0; $i < count($Fname); $i++ )
{
echo $Fname[$i] . PHP_EOL;
echo $Lname[$i] . PHP_EOL;
echo $Addrs[$i] . PHP_EOL;
echo $Mobile[$i] . PHP_EOL;
if( isset(current($fields)) )
{
echo current($fields) . PHP_EOL;
next($fields);
}
}
i know this way is false...? What's false about it?
foreach() will iterate over an array, not over multiple arrays.... if you absolutely need to iterate over multiple arrays within the same foreach() loop, you can use SPL's MultipleIterator, but it adds a lot more complexity to your code, and the approach that you've taken is as good as any
Just make sure that your keys match up in all the arrays; if they don't then you will have problems
foreach(array_values($fields) as $key => $n)
{
$k = array_keys($fields)[$key];
echo " {$Fname[$key]} , {$Lname[$key]},{$Addrs[$key]} , {$Mobile[$key]},{$k} ,{$n} <br>";
}
Instead of storing your data like that, it'd be easier to store it in an array of associative arrays:
$people = array(
array(
'firstName' => 'Bruce',
'lastName' => 'Wayne',
'address' => '123 East St. Gotham City, XX USA'
'mobile' => '847-847-8475'
),
array(
'firstName' => 'Roland',
'lastName' => 'Deschain',
'address' => 'N/A'
'mobile' => '191-919-1919'
)
);
foreach($people as $person){
echo $person['firstName'] + ', ' + $person['lastName'];
echo $person['address'] + ', ' + $person['mobile'];
}
It's just a cleaner way to store/access your data, makes it easy to use one foreach as well.
Try this code
$arr1 = array("a" => 1, "b" => 2, "c" => 3);
$arr2 = array("x" => 4, "y" => 5, "z" => 6);
foreach ($arr1 as $key => &$val) {}
foreach ($arr2 as $key => $val) {}
var_dump($arr1);
var_dump($arr2);
I'm trying to get sum and average of visitors from the following multi-dimensional array :
Array([visitors] => Array(
[2015-06-12] => Array([0] => Array([value] => 29))
[2015-06-11] => Array([0] => Array([value] => 55))
...
))
I cannot manage to find a way to get the results i need as i get lost with "foreach".
Can anybody help please ?
Use this
<?php
$mainarray = array('visitors' => Array(
'2015-06-12' => Array(Array('value' => 29)),
'2015-06-11' => Array(Array('value' => 55))));
$sum = 0;
$count = 0;
$visitor = $mainarray['visitors'];
foreach ($visitor as $key => $val) {
$sum += $val[0]['value'];
$count++;
}
echo "Sum is " . $sum."<br>";
$average = ($sum / $count);
echo "Average is " .$average."<br>";;
?>
