my script :
$reverse_sets = array_reverse($sets);
foreach ($extraset as $element) {
foreach ($sets as $index => $set) {
if (in_array($element, $set)) {
$actual_index = count($sets)-$index-1;
echo "Extraset element '$element' is in set $actual_index<br>";
break;
}
}
}
outputs me an $actual_index serie of numbers, from 20 to 0.
I need to reverse the output of $actual_index displaying the numbers backwards (from 0 to 20), without touching the previous logic of the script.
I tried using again array reverse on $actual_index, creating $final_index :
$reverse_sets = array_reverse($sets);
foreach ($extraset as $element) {
foreach ($sets as $index => $set) {
if (in_array($element, $set)) {
$actual_index = count($sets)-$index-1;
$final_index = array_reverse($actual_index);
echo "Extraset element '$element' is in set $final_index<br>";
break;
}
}
}
but i don't get any output.
What is wrong with my code ? How do I fix this ? thanks for your help

I have this code using an api , the first iteration is showing everything right , but at the second iteration is showing the items from the first iteration + the items from the second iteration , and the same thing at the third iteration.
I dont want that , how can i fix that problem ?
$g=0;
foreach ($matches as $match) {
$inside = $api->getMatch('123');
$pp = $api->getMatchTimeline('123');
foreach ($inside->participants as $partId) {
if ($partId->championId == $match->champion) {
$participant_id[] = $partId->participantId;
$participant_idS = $partId->stats->participantId;
foreach ($pp->frames as $p) {
foreach ($p->events as $t) {
if ($t->type == "ITEM_PURCHASED" and $t->participantId == $participant_idS) {
$item_id = $t->itemId;
$d = $api->getStaticItem($item_id);
if($d->depth == 2 or $d->depth == 3){
$itemsMade[] = $d->id;
}
}
}
}
}
}
$dt = [['match_ids' => $part, "champion" => $soloq->champion, "timestamp" => $match->timestamp, "participantId" => $participant_id[$g++], "itens" => json_encode($itemsMade)]
];
echo ' <pre>';
var_dump($dt);
echo '</pre>';
}
You need to set that array to be empty at the start of your loop. Otherwise you just keep adding to it as you see in your output.
foreach ($inside->participants as $partId) {
$itemsMade = [];
Using below array, i'm trying to use foreach loop to iterate through each item. Then i need to apply if condition to check if the given number is even and odd. I also need to create two arrays one for even and one for odd and push each number in their respective category.
So i have done this so far:
These are the two arrays i created to push through the values to.
}
$numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14];
$array_odd = [];
$array_even = [];
foreach ($numbers as $value)
{
if (value %2 == 0)
{
$array_even = $value;
echo $array_even;
}
else
{
$array_odd = $value;
echo $array_odd;
}
I'd like to know if i'm using the correct solution or are there major errors im committing?
It will surely work like charms.
$numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14];
$array_odd = [];
$array_even = [];
foreach ($numbers as $value)
{
if ($value %2 == 0)
{
$array_even[] = $value;
}
else
{
$array_odd[] = $value;
}
}
echo "<pre>";
print_r($array_odd);
echo "<pre>";
print_r($array_even);
I want to remove or hide duplicate values in loop , It's not array.
You can see in picture 1/3, & 2/2 is repeating so I want only once using loop. It's not return any array it's simple data so we can't use array_unique
$i=1;
$result = array();
foreach ($boxes as $key => $value) {
foreach ($result as $k => $val) {
echo $i."/".count($value).'</br>';
}
$i++;
}
Expected Output
REG-Pre-Cut Short 1/3
REG-Pre-Cut Long -
PREM-Pre-Cut Short -
PREM-Pre-Cut Short 2/2
PREM-Pre-Cut Long -
Try something like this.
First you create an array in the expected format.
Then use array_unique to remove duplicates.
Then you print out the array.
$i=1;
$result = array();
$outputResult = array();
foreach ($boxes as $key => $value) {
foreach ($result as $k => $val) {
$outputResult[] = $i."/".count($value).'</br>';
}
$i++;
}
$outputResult = array_unique($outputResult);
foreach ($outputResult as $result) {
echo $result;
}
I have following array construction: $array[$certain_key][some_text_value]
And in a while loop, I want to print the data from the array, where $certain_key is a specific value.
I know how to loop through multidimensional arrays, which is not the complete solution to this problem:
foreach ($a as $v1) {
foreach ($v1 as $v2) {
echo "$v2\n";
}
}
I do not want to loop the whole array each time, but only when $certain_key is matched.
EDIT: to be more exact, this is what I'm trying to do:
$array[$array_key][some_text];
while reading from db {
//print array where a value returned from the db = $array_key
}
while ($row = fetch()) {
if (isset($array[$row['db_id']])) {
foreach ($array[$row['db_id']] as $some_text_value => $some_text_values_value) {
echo ...
}
}
}
foreach ($array as $certain_key => $value) {
if($certain_key == $row['db_id']) {
foreach ($value as $some_text_value) {
echo "$v2\n";
}
}
}
You mean like
foreach($array[$certain_key] as $k => $v)
{
do_stuff();
}
?
Maybe you're looking for array_key_exists? It works like this:
if(array_key_exists($certain_key, $array)) {
// do something
}
<?php
foreach ($a as $idx => $value) {
// replace [search_value] with whatever key you are looking for
if ('[search_value]' == $idx) {
// the key you are looking for is stored as $idx
// the row you are looking for is stored as $value
}
}
Using a regular for loop, it's possible to comapred the current index with the last to tell if I'm in the last iteration of the loop. Is there a similar thing when using foreach? I mean something like this.
foreach($array as $item){
//do stuff
//then check if we're in the last iteration of the loop
$last_iteration = islast(); //boolean true/false
}
If not, is there at least a way to know the current index of the current iteration like $iteration = 5, so I can manually compare it to the length of the $array?
The counter method is probably the easiest.
$i = count($array);
foreach($array as $item){
//do stuff
//then check if we're in the last iteration of the loop
$last_iteration = !(--$i); //boolean true/false
}
You can use a combination of SPL’s ArrayIterator and CachingIterator class to have a hasNext method:
$iter = new CachingIterator(new ArrayIterator($arr));
foreach ($iter as $value) {
$last_iteration = !$iter->hasNext();
}
Here are a few methods for this;
$items = ["Bhir", "Ekky", null, "Uych", "foo"=>"bar"];
$values = array_values($items);
// Bhir, Ekky, Uych, bar
foreach ($values as $i => $item) {
print("$item");
$next = isset($values[$i + 1]);
if ($next) {
print(", ");
}
}
// Bhir, Ekky, , Uych, bar
foreach ($values as $i => $item) {
print("$item");
$next = array_key_exists($i + 1, $values);
if ($next) {
print(", ");
}
}
// Bhir, Ekky, , Uych, bar
$i = count($values);
foreach ($items as $item) {
print("$item");
$next = !!(--$i);
if ($next) {
print(", ");
}
}
// Bhir, Ekky, , Uych, bar
$items = new \CachingIterator(new \ArrayIterator($items));
foreach ($items as $item) {
print("$item");
$next = $items->hasNext();
if ($next) {
print(", ");
}
}
No, you need to have a counter and know the amount of items in the list. You can use end() to get the last item in an array and see if it matches the current value in your foreach.
If you know that the values of the array will always be unique, you can compare the current $item to end($array) to know if you're at the last item yet. Otherwise, no, you need a counter.
You can get the key and the value in foreach() like this:
foreach($array as $key=>$value) { ... }
Alternatively, you could do a count() of the array so you know how many items there are and have an incrementing counter so that you know when you've reached the last item.
end($array);
$lastKey = key($array);
foreach($array as $key => $value) {
if ($key === $lastKey) {
// do something endish
}
}
The valid() method says if the ArrayIterator object has more elements.
See:
$arr = array("Banana","Abacaxi","Abacate","Morango");
$iter = new ArrayIterator($arr);
while($iter->valid()){
echo $iter->key()." - ".$iter->current()."<br/>";
$iter->next();
}
