I'm trying to print array. All code working fine with foreach loop. But I'm trying to print with associated keys. Is it possible?
Example: key['user_id'] this will print all user_id from array. is it possible? please help me thanks
Array
(
[Post1] => Array
(
[id] => 1
[title] => hi
)
[Post2] => Array
(
[0] => Array
(
[user_id] => 1
)
[1] => Array
(
[user_id] => 2
)
)
[Post3] => Array
(
[0] => Array
(
[user_name] => 1
)
)
)
Here is my PHP code:
foreach($post as $key => $value) {
foreach($value as $print => $key) {
if (is_array($key)){
foreach($key as $print2 => $key2) {
echo "<br>".$key2;
}
}else{
echo "<br>".$key;
}
}
}
You can print_r to achive the same results you want with your triple for each.

You can easily use recursion for such a problem. You can use something along the lines of:
function printValuesByKey($array, $key) {
if (!is_array($array)) return;
if (isset($array[$key]))
echo $key .': '. $array[$key] .'<br>';
else
foreach ($array as $v)
printValuesByKey($v, $key);
}
In your example:
printValuesByKey($array, 'user_id');
will print:
user_id: 1
user_id: 2

Array
(
[data] => Array
(
[0] => Array
(
['degree_level'] => Bachelor's
)
[1] => Array
(
['field_of_study'] => Science
)
[2] => Array
(
['grade_point'] => 3
)
[3] => Array
(
['criteria'] => desired
)
)
)
What I want :
Array
(
[data] => Array
(
['degree_level'] => Bachelor's
['field_of_study'] => Science
['grade_point'] => 3
['criteria'] => desired
)
)
You should use array_flatten(); to achieve your goal like this,
$flattened = array_flatten(Your_Data_Array);
Please give it a try and let me know.
UPDATE
$flattened = array_map(function($item) {
return $item[0];
}, Your_Data_Array);
For more information you can visit this for PHP functions.
Let me know in case of any queries.
$output = array_map(function($item) { return $item[0]; }, $myArray);
Try this,
foreach($data as $key1=>$val1){
foreach($val1 as $key2=>$val2){
$new_array[$key2] = $val2;
}
}
You can do it by loop.
foreach ($data as $key => $value) {
foreach ($value as $key1 => $value2) {
$data[$key1] = $value2;
}
}
You could use for example a double foreach loop to use the key and the value from the second loop and add those to the $arrays["data"] array.
Then you could use unset to remove the nested arrays.
$arrays = [
"data" => [
["degree_level" => " Bachelor's"],
["field_of_study" => "Science"],
["grade_point" => 3],
["criteria" => "desired"]
]
];
foreach($arrays["data"] as $dataKey => $data) {
foreach ($data as $key => $value) {
$arrays["data"][$key] = $value;
}
unset($arrays["data"][$dataKey]);
}
print_r($arrays);
That would give you:
Array
(
[data] => Array
(
[degree_level] => Bachelor's
[field_of_study] => Science
[grade_point] => 3
[criteria] => desired
)
)
Demo
you can achieve this using array_collapse.

EDIT :
while tag has changed.
Here is the core php solution based on Laravel array_collapse:
function collapse($array)
{
$results = [];
foreach ($array as $values) {
if (! is_array($values)) {
continue;
}
$results = array_merge($results, $values);
}
return $results;
}
Array
(
[edit] => true
[id] => 1
[type] => Array
(
[0] => LC
)
[userid] => 1
[norooms] => 1
[park] => Central
[start] => 09:00
[end] => 11:00
[length] => 2
[student] => 79
[status] => Rejected
)
<?php
$posted_data = array();
if (!empty($_POST['edit'])) {
$posted_data = json_decode($_POST['editVal'], true);
}
print_r ($posted_data);
foreach ($posted_data as $key => $value) {
echo '<p>'.$key.'</p>';
echo '<p>'.$value.'</p>';
}
?>
The array at the top is the jason_decode returned. However with my foreach function it does not display the first index of the array within the array. ie. ( [0] => LC ).
Where am I going wrong?
You need to build a recursive function, something like:
function print_recursively(array $array)
{
foreach ($array as $key => $value)
{
if(is_array($value))
{
print_recursively($value);
}
else
{
echo '<p>'.$key.'</p>';
echo '<p>'.$value.'</p>';
}
}
}
Tune it according to your needs.
If you know there is array hierarchy to one level only
Keep printing the values and if the value is an array using is_array.. Iterate again.
foreach($dataArray as $key =>$value){
if(is_array($value)){
foreach($value as $array2Data){
echo $array2Data; //you can use keys as well
}
}
else
echo $value;
}
I am a little confused about the array_search function (or maybe I am trying to use the incorrect thing.) I have a bunch of transaction objects, (transactions about a customer) each is an array of values. After passing in an email address, I get an object that is one transaction where that email address was used. Example is below. I get it from the command print_r($results):
stdClass Object
(
[OverallStatus] => OK
[RequestID] => 4564564654-65465464565-4654654
[Results] => Array
(
[0] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 5555555555
[email_addy] => someaddy#something.com
)
[1] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 6666666666
[email_addy] => someaddy#something.com
)
[2] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 6666666666
[email_addy] => someaddy#something.com
)
)
)
I get this output with no trouble at all. My issue is that I need to identify when someone has a specific ID. I was trying to use a foreach but I am not getting back what I need. The code and output is below.
foreach ($results as $key => $value) {
echo "Key: $key; Value: $value<br />\n";
}
Output is
Key: OverallStatus; Value: OK
Key: RequestID; Value: 4564564654-65465464565-4654654
Key: Results; Value: Array
All I really need to know is if the customer has an ID of 5555555555. This number will always stay the same. Am I going in the wrong direction here?
You have array of object , so you should get first the array results , and then iterate over it,try this :
foreach ($results->Results as $key => $value) {
if($value->ID == 55555555) echo 'found at position'.$key;//if id is unique , add a break;
}
You need to iterate through $results->Results.
foreach ($results->Results as $key => $value) {
if($value->ID == 5555555555)
print "Match found";
}
You should loop again for results array. Try following foreach
foreach ($results as $key => $value) {
if($key == "Results") {
foreach($value as $v) {
if($v->ID == "5555555555") {
echo "I found you";
break;
}
}
} else {
echo "Key: $key; Value: $value<br />\n";
}
}
Loop through '$results->Results' and check in loop if the ID=5555555555 like this:
foreach ($results->Results as $value) {
if($value->ID == 5555555555) {
//do something
}
}
It would be something like the following:
$transactions = $results->Results; //get results array
foreach ($transactions as $transaction) { // loop through each transaction object.
echo $transaction->ID . '<br />'; // print out the id of each transaction.
}
I have a $search_array like this
Array
(
[1] => Array
(
[type] => book
[search] => steve
)
[2] => Array
(
[type] => book
[search] => john
)
foreach ($search_array as $s) {
$arrayid = //???????
$searchtype = $s['type'];
$search = urlencode($s['search']);
getResult($arrayid);
}
I'm trying to figure out how to get the array number. So for the first result i need $arrayid to be 1. How do I reference that in the foreach loop?
Thanks
Use a foreach with "$key => $value"
Array
(
[1] => Array
(
[type] => book
[search] => steve
)
[2] => Array
(
[type] => book
[search] => john
)
foreach ($search_array as $key => $s) {
$arrayid = $key
$searchtype = $s['type'];
$search = urlencode($s['search']);
getResult($arrayid);
}
Adding $arrayid => in your foreach loop declaration will auto-assign $arrayid with the current array index.
foreach ($search_array as $arrayid => $s) {
// ...
getResult($arrayid);
}
See foreach on PHP Manual.
foreach ($search_array as $arrayid => $s) {
Please read PHP documentation before asking such basic questions
foreach ($search_array as $arrayid => $s) {
// your code here
}
This is a way you could retrieve data from a Php array. It will retrieve all entries from array $value and their key $key.
foreach ($array as $key => $value) {
// $key is the array index
}
I'm trying to print array. All code working fine.But at last I'm getting `ArrayArray'. Can any one solve this problem. many many thanks
here is my array
Array
(
[Post1] => Array
(
[id] => 1
[title] => hi
)
[Post2] => Array

[0] => Array
(
[id] => 1
)
)
[Post3] => Array
(
[0] => Array
(
[id] => 1
)
)
)
Here is my PHP Code
foreach($post as $key => $value) {
foreach($value as $print => $key) {
echo "<br>".$key;
}
}
here is output
ID
Array
Array
Try this:
foreach($post as $key => $value) {
foreach($value as $print => $key) {
if (is_array($key)){
foreach($key as $print2 => $key2) {
echo "<br>".$key2;
}
}else{
echo "<br>".$key;
}
}
}
The to string method of an array is to return "Array".
It sounds like you want to view the array for debugging purposes. var_dump() is your friend :)
you are trying to print an array, resulting in Array.
If you want to print an array use print_r
I think the trouble for you is that you have $key in the outer loop and $key in the inner loop so its really confusing which $key you are talking about for starters.
You just want the stuff printed out to debug?
echo "<pre>" . print_r( $post , true ) . "</pre>\n";
