I am having issue with execution of nested foreach loop execution for desired result. Below is the scenario:
Following are result in two arrays
Result1:
Array ( [0]=> Array ( [questionID] => 103 [answer] => Female [answer_cnt] => 8 )
[1] => Array ( [questionID] => 103 [answer] => Male [answer_cnt] => 9 )
)
Result2
Array ( [0] => Male [1] => Female )
my code using foreach loop is below
foreach($qrs as $qrow)
{ foreach($d as $q){
echo"<br>".$q;
echo $qrow['answer_cnt']."<br>";}
}
it will get output :
Male 8
Female8
Male 9
Female9
But My Expected output is
Female 8
Male 9
You don't need to loop on the second. Just use the first one.
foreach($qrs as $qrow) {
echo $qrow['answer'] . ' ' . $qrow['answer_cnt'] . '<br/>';
}
Its quite unclear why do you need the second array but if you want to include it (which makes no sense), just include an if.
foreach($qrs as $qrow) {
foreach($d as $q) {
if($qrow['answer'] == $q) {
echo $qrow['answer'] . ' ' . $qrow['answer_cnt'] . '<br/>';
}
}
}
Your second array is useless. just do:
foreach($qrs as $qrow)
{
echo"<br>".$qrow['answer']." ";
echo $qrow['answer_cnt']."<br>";}
}
use this...
foreach($qrs as $qrow)
{
foreach($d as $q)
{
if(in_array($q, $qrow))
{
echo"<br>".$q;
echo $qrow['answer_cnt']."<br>";
}
}
}
$arr = array(
array( 'questionID' => 103, 'answer' => 'Female', 'answer_cnt' => 8),
array( 'questionID' => 103, 'answer' => 'Male', 'answer_cnt' => 9)
);
if(count($arr) > 0) {
foreach($arr as $val) {
echo "$val[answer] $val[answer_cnt] <br />";
}
}
you can also try this one.

I have some confusing issue here. please take a look and help if you don't mind.
let's say i have this multidimensional array, called $array.
[1] => Array
(
[3] => 2
[2] => 5
[4] => 4
)
[3] => Array
(
[1] => 2
)
[2] => Array
(
[1] => 5
)
that array is representing a path between two node. I try to implmenting dijkstra algorhitm here. when it's
$array[1][2] = 5
that's mean the distance between node 1 to node 2 is 5 and so on.
what Im asking is, how can I detect that array $array[1][4] = 4 doesn't have a reverse path such $array[4][1] = 4 like the example above.
thank you in advance.
Follow this:
$temp = array();
$array = array('1' => Array
(
'3' => 2,
'2' => 5,
'4' => 4
),
'3' => Array
(
'1' => 2
),
'2' => Array
(
'1' => 5
));
foreach ($array as $key => $value)
{
foreach ($value as $k => $v)
{
if($array[$key][$k] == isset($array[$k][$key]))
{
echo $key . 'to' . $k . 'reverse path available';
echo "<br>";
}
}
}
Like this.Loop foreach inside another foreach and check based on keys.
$array = array('1'=>array('3'=>2),'3'=>array('1'=>2));//assumed reversed array
//print_r($array);
foreach($array as $key=>$value){
foreach($value as $k=>$v){
if($array[$key][$k] == $array[$k][$key]){
echo "Reverse at:array[".$key."][".$k."]".PHP_EOL;
continue;
}
}
}
Output:
Reverse at:array[1][3]
Reverse at:array[3][1]
for that array you have to add nested for loop..
for($i=0;$i<count($your_array);$i++)
{
for($j=0;$j<count($your_array[$i]);$j++)
{
if(isset($your_array[$i][$j]) && isset($your_array[$j][$i]) && $your_array[$i][$j]==$your_array[$j][$i])
{
echo "same distance";
}
else
{
echo "different distance or path not available";
}
}
}
I have a multidimensional array.I want to extract this array through foreach loop and want to display in a unordered list. how to solve this. please help me. i am trying for 2 days but could not get any solution. i think i'm weak in loop.
Array
(
[id] => 1
[name] => Funny
[category_details] => Array
(
[get_everything] => Array
(
[0] => Array
(
[ci_cat_id] => 1
[img_name] => fapore kapor nosto
)
)
)
)
Array
(
[id] => 4
[name] => Events
[category_details] => Array
(
[get_everything] => Array
(
[0] => Array
(
[ci_cat_id] => 4
[img_name] => elo khushir eid
)
[1] => Array
(
[ci_cat_id] => 4
[img_name] => Eid e bari jacchi
)
)
)
)
i want the output like this
category name1:
1. test1
2. test2
3. test3
category name2:
1. test4
2. test5
3. test6
You need to use the array_column(). First of all you need to loop the array and get the category names, and also you need to get the img_name, for this you have to use the array_column and that function gives you the array of that img_name, so now again loop this new array and print the img_name.
Your array:
$arr = array(
array(
"id" => 1,
"name" => "Funny",
"category_details" => array(
"get_everything" => array(
array(
"ci_cat_id" => 1,
"img_name" => "fapore kapor nosto"
)
)
)
),
array(
"id" => 4,
"name" => "Events",
"category_details" => array(
"get_everything" => array(
array(
"ci_cat_id" => 4,
"img_name" => "elo khushir eid"
),
array(
"ci_cat_id" => 4,
"img_name" => "Eid e bari jacchi"
)
)
)
)
);
procedure:
foreach($arr as $val){
echo $val['name']."<br/>";
$i = 1;
$img_name = array_column($val['category_details']['get_everything'], 'img_name');
foreach($img_name as $v){
echo $i++.' - '.$v."<br/>";;
}
}
Output:
Funny
1 - fapore kapor nosto
Events
1 - elo khushir eid
2 - Eid e bari jacchi
Try this will may help you,
1) If you want array:
foreach ($array as $k=>$v){
foreach ($v['category_details']['get_everything'] as $key => $val){
$finalArray[$v['name']][] = $val['img_name'];
}
}
Output will look like this,
Array
(
[Funny] => Array
(
[0] => fapore kapor nosto
)
[Events] => Array
(
[0] => elo khushir eid
[1] => Eid e bari jacchi
)
)
2)If You want string :
foreach ($array as $k=>$v){
echo $v['name'].'<br/>';
$i=1;
foreach ($v['category_details']['get_everything'] as $key => $val){
echo $i.'. '.$val['img_name'].'<br/>';
$i++;
}
}
Output Will be,
Funny
1. fapore kapor nosto
Events
1. elo khushir eid
2. Eid e bari jacchi
try this one
foreach($array as $value) {
echo $value['name'];
foreach($value['category_details'] as $val) {
$i=1;
foreach($val as $v) {
echo $i++ . '. ' . $v['img_name'];
}
}
}
hope this help..

I have this array $pages which spits out this data:
Array (
[Name] => Array (
[Subname] => Array (
[0] => 43.2057, -79.9632, 1, -70,-150
[1] => 140240757658.jpg
[2] => 5
[3] => 0
) )
[Name2] => Array (
[Subname2] => Array (
[0] => 43.1769, -79.4703, 5, -70,-150
[1] => 140267498933.png
[2] => 16
[3] => 0
) )
)
and I have this foreach setup:
foreach($pages as $row => $value) {
echo '<li>'.$row.'<ul>';
foreach($value as $x => $y) {
echo
'<li>
'.$x.'
</li></ul></li>';
}
}
What I am trying to do is if [3] in each of the Subname is equal to 0, then skip it from my foreach.
NOTE: Subname and Name are just examples, they will be different for each one.
This should work:
foreach ($pages as $page) {
foreach($page as $subname) {
if ($subname[3] != 0) {
/* Do whatever you want with the data of this subname */
}
}
}
Or this if you want to use the key names:
foreach ($pages as $pageKey => $page) {
foreach($page as $subnameKey => $subname) {
if ($subname[3] != 0) {
/* Do whatever you want with the data of this subname */
}
}
}
If you want to skip the sub-foreach then this is the solution
foreach($pages as $row => $value) {
if($value['Subname'][3] == 0)
continue;
echo '<li>' . $row . '<ul>';
foreach($value as $x => $y) {
echo '<li>' . $x . '</li></ul></li>';
}
}
Since this is an Associative Array you will not be able to to check
$pages['foo']['bar'][0] === 0
before the first foreach begins since we don't know the value of $pages['foo'] before hand. when we get to the check you have already output html at the point in the form of:
echo '<li>' . $row . '<ul>';
Hi,
How can we find the count of duplicate elements in a multidimensional array ?
I have an array like this
Array
(
[0] => Array
(
[lid] => 192
[lname] => sdsss
)
[1] => Array
(
[lid] => 202
[lname] => testing
)
[2] => Array
(
[lid] => 192
[lname] => sdsss
)
[3] => Array
(
[lid] => 202
[lname] => testing
)
)
How to find the count of each elements ?
i.e, count of entries with id 192,202 etc
You can adopt this trick; map each item of the array (which is an array itself) to its respective ['lid'] member and then use array_count_value() to do the counting for you.
array_count_values(array_map(function($item) {
return $item['lid'];
}, $arr);
Plus, it's a one-liner, thus adding to elite hacker status.
Update
Since 5.5 you can shorten it to:
array_count_values(array_column($arr, 'lid'));
foreach ($array as $value)
{
$numbers[$value[lid]]++;
}
foreach ($numbers as $key => $value)
{
echo 'numbers of '.$key.' equal '.$value.'<br/>';
}
Following code will count duplicate element of an array.Please review it and try this code
$arrayChars=array("green","red","yellow","green","red","yellow","green");
$arrLength=count($arrayChars);
$elementCount=array();
for($i=0;$i<$arrLength-1;$i++)
{
$key=$arrayChars[$i];
if($elementCount[$key]>=1)
{
$elementCount[$key]++;
} else {
$elementCount[$key]=1;
}
}
echo "<pre>";
print_r($elementCount);
OUTPUT:
Array
(
[green] => 3
[red] => 2
[yellow] => 2
)
You can also view similar questions with array handling on following link
http://solvemyquest.com/count-duplicant-element-array-php-without-using-built-function/
The following code will get the counts for all of them - anything > 1 at the end will be repeated.
<?php
$lidCount = array();
$lnameCount = array();
foreach ($yourArray as $arr) {
if (isset($lidCount[$arr['lid']])) {
$lidCount[$arr['lid']]++;
} else {
$lidCount[$arr['lid']] = 1;
}
if (isset($lnameCount [$arr['lname']])) {
$lnameCount [$arr['lname']]++;
} else {
$lnameCount [$arr['lname']] = 1;
}
}
$array = array('192', '202', '192', '202');
print_r(array_count_values($array));
$orders = array(
array(
'lid' => '',
'lname' => '',
))....
$foundIds = array();
foreach ( $orders as $index => $order )
{
if ( isset( $foundIds[$order['lid']] ) )
{
$orders[$index]['is_dupe'] = true;
$orders[$foundIds[$order['lid']]]['is_dupe'] = true;
} else {
$orders[$index]['is_dupe'] = false;
}
$foundIds[$order['lid']] = $index;
}
Try this code :
$array_count = array();
foreach ($array as $arr) :
if (in_array($arr, $array_count)) {
foreach ($array_count as $key => $count) :
if ($key == $arr) {
$array_count[$key]++;
break;
}
endforeach;
} else {
$array_count[$arr] = 1;
}
endforeach;
Check with in_array() function.
Below is foreach and the 3 dimension arrays, no problem with the looping but i cannot sepcify which array to echo, they must me the whole arrays like echo $subvalue, any better solutions with looping 3 dimension array? i actually feel weird with this looping. Thanks in adv
foreach ($stories as $key => $story){
//echo "<br />";
foreach($story as $subkey => $subvalue){
echo $subvalue."<br />";
foreach($subvalue as $key => $subsubvalue){
echo $subsubvalue."<br />";
}
}
}
Array
(
[270] => Array
(
[uid] => 36
[user_email] => aaa#hotmail.com
[sid] => 270
[story_name] => Story C
[photo_url] => Array
(
[0] => story_photos/2012/0322/361332381418153311.jpg

Why not try this :
foreach ($stories as $key => $story){
if(is_array($story)){
foreach($story as $subkey => $subvalue){
if(is_array($subvalue)){
foreach($subvalue as $key => $subsubvalue){
echo $subsubvalue."<br />";
}
} else {
echo $subvalue."<br />";
}
}
} else {
echo $story."<br />";
}
}
Also, I am not sure because your question isn't really clear or specified.
Or
function echoArray( $array )
{
foreach ($array as $key => $cell)
{
if ( true == is_array($cell) )
{
echoArray($cell);
}
else
{
echo "$cell<br />";
}
}
}
It works for N dimensionnal array
An improved version to know the depth and use different css class for depth and to use set the tag in which the value should be added:
Eg: for depth 0 the class will by arrayclass_0, for depth 1 arrayclass_1, etc...
/**
$array : The array
$depth: The depth ( you should always set it to 0)
$cssclassprefix: The css class prefix you want to set
$tag: the default tag to use to render
$arraytagkey: An optionnal key in your array to extract the tag to use
*/
function echoArray( $array, $depth=0, $cssclassprefix='arrayclass_', $tag='div', $arraytagkey = '' )
{
if ( 0 != strcmp($arraytagkey) && isset($array[$arraytagkey]) )
{
$tag=$array[$arraytagkey];
}
foreach ($array as $key => $cell)
{
if ( true == is_array($cell) )
{
echoArray($cell, $depth+1, $cssclassprefix, $tag, $arraytagkey);
}
else
{
$matches = array();
if ( 0 != preg_match("/^(img|iframe|input)$/i",$tag) )
{
if ( 0 != strcasecmp('input',$tag) )
{
echo "<input class='$cssclassprefix$depth' value='$cell' />";
}
else
{
echo "<$tag class='$cssclassprefix$depth' src='$cell' />";
}
}
else if( 0 != preg_match("/^(br|hr)$/i",$tag) )
{
echo "$cell<$tag />";
}
else
{
echo "<$tag class='$cssclassprefix$depth'>$cell</$tag>";
}
}
}
}
This doesn't really answer your question, but note, your third loop is this:
foreach ($subvalue as $key => $subsubvalue){
But you've already used $key in the first loop:
foreach ($stories as $key => $story){
You should change the third to:
foreach ($subvalue as $subsubkey => $subsubvalue){
Are you just wanting to loop through and get access to the photo_urls and other data? If that's the case then here's a simple example of how you can access the data:
foreach($stories as $key => $story)
{
// here you can echo the $store['user_email'] etc
echo 'Email: ' . $story['user_email'] . '<br />';
// loop over the photo urls
foreach($story['photo_url'] as $photo_url)
{
echo 'Photo URL: ' . $photo_url . '<br />';
}
// loop over the photo added dates
foreach($story['photo_added_date'] as $photo_added_date)
{
echo 'Photo Date: ' . $photo_added_date . '<br />';
}
}
If you're wanting to recursively search the array then the other answers are what you want.
