Hey all i am trying to get the data from a movie API. The format is this:
page => 1
results =>
0 =>
adult =>
backdrop_path => /gM3KKixSicG.jpg
id => 603
original_title => The Matrix
release_date => 1999-03-30
poster_path => /gynBNzwyaioNkjKgN.jpg
popularity => 10.55
title => The Matrix
vote_average => 9
vote_count => 328
1 =>
adult =>
backdrop_path => /o6XxGMvqKx0.jpg
id => 605
original_title => The Matrix Revolutions
release_date => 2003-10-26
poster_path => /sKogjhfs5q3aEG8.jpg
popularity => 5.11
title => The Matrix Revolutions
vote_average => 7.5
vote_count => 98
etc etc....
How can i get only the first element [0]'s data (as in backdrop_path, original_title, etc etc)? I'm new at PHP arrays :).
And of course this is what i used to output my array data:
print_r($theMovie)
Any help would be great!
Another solution:
$arr = reset($datas['results']);
Returns the value of the first array element, or FALSE if the array is empty.
OR
$arr = current($datas['results']);
The current() function simply returns the value of the array element that's currently being pointed to by the internal pointer. It does not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, current() returns FALSE.
You can point to the array with this $theMovie['result'][0]['backdrop_path']; or you can loop through it like this,
foreach($theMovie['results'] as $movie){
echo $movie['backdrop_path'];
}
You can use array_shift to pop off the first element, then check that it is valid (array_shift will return null if there are no results or the item isn't an array).
$data = array_shift($theMovie['results']);
if (null !== $data) {
// process the first result
}
If you want to iterate though all the results, you can do a foreach loop while loop with array_shift.
foreach($theMovie['results'] as $result) {
echo $result['backdrop_path'];
}
while ($data = array_shift($theMovie['results'])) {
echo $data['backdrop_path'];
}
Or just use $theMovie['result'][0]['backdrop_path']; as already suggested, after checking that $theMovie['result'][0] is actually set.
Assuming all this code is stored in a variable $datas :
$results = $datas['results'];
$theMovie = $results[0];
Try
$yourArray['results'][0]
But keep in mind this produces errors when the result array is empty.

Can i make multidimensionalarrry to assosiative array, Right now i am getting following result
Array
(
[0] => Array
(
[id] => 1
[minimum_marks] => 55
[maximum_marks] => 65
)
[1] => Array
(
[id] => 2
[minimum_marks] => 44
[maximum_marks] => 70
}
)
I just want to put all values in single, i want result like following array
Array
(
[id] => 1
[minimum_marks] => 55
[maximum_marks] => 65
)
Array
(
[id] => 2
[minimum_marks] => 44
[maximum_marks] => 70
)
Here is my code,My code not showing only one record with loop (code should showing all minimum_marks and maximum_marks), where i am wrong ?
$result = $query->result_array();
$simpleArray = [];
foreach ($result as $skuArray) {
$simpleArray['minimum_marks'] = $skuArray['minimum_marks'];
$simpleArray['maximum_marks'] = $skuArray['maximum_marks'];
}
print_R($simpleArray);
I don't know why are you expecting this output. But my suggestion, if you want it really?
$simpleArray = [];
foreach ($result as $skuArray) {
$simpleArray['minimum_marks'] = $skuArray['minimum_marks'];
$simpleArray['maximum_marks'] = $skuArray['maximum_marks'];
print_R($simpleArray);
}
Print the value inside loop, so it wont push and it wont create multiple array. every time, it will overwrite. But please be sure, finally you get last array value only on the simpleArray. Hope you understood!
Let me explain with example. If you want to display the marks in table, I will suggest you to return directly like below instead of creating variable and retrieving it again.
echo '<table>
<tr><th>Min Marks</th><th>Max Marks</th></tr>';
foreach ($result as $skuArray) {
$minMarks = $skuArray['minimum_marks'];
$maxMarks = $skuArray['maximum_marks'];
echo '<tr><td>'.$minMarks.'</td><td>'.$minMarks.'</td></tr>';
}
echo '</table>';
I don't really understand what you want.
If you want to get your array in two different variables you can try this:
Use dynamic variables, the name of the variable is dynamically generated in your loop.
foreach($result as $key => $_array){
//$key is your inder of you multidimensional
$name_variable = '_array_number_'.$key; //Name of the variable
$$name_variable = $_array; //Instanciate dynamic variable
}
//You got now this two array
print_r($_array_number_0);
print_r($_array_number_1);
But please be more precise next time with what you expect and why you need this.
By the way, what happened to your code is that in the first loop you instanciate 'minimum_marks' and 'maximum_marks' in $_simple_array.
But in your second loop you overwrite the value of 'minimum_marks' and 'maximum_marks'.
As a newbie, does anyone have any good tutorials to help me understand different levels of an array? What I'm trying to learn is how to echo different levels, e.g. here is the output array:
Array
(
[meta] =>
Array
(
[total_record_count] => 1
[total_pages] => 1
[current_page] => 1
[per_page] => 1
)
[companies] =>
Array
(
[0] =>
Array
(
[id] => 291869
[url] => https://api.mattermark.com/companies/291869
[company_name] => gohenry.co.uk
[domain] => gohenry.co.uk
)
)
[total_companies] => 1
[page] => 1
[per_page] => 1
)
And here is the code to parse the array:
foreach($jsonObj as $item)
{
echo $item['total_companies'];
}
I'm really struggling to find the structure and how to output each items, e.g. tried things like:
echo $item[0]['total_companies'];
echo $item['companies'][0]['id'];
Any help or pointers would be greatly received.
Well, Lets start, You have a multi-dimensional array. For a multi-dimensional array you need to use looping e.g: for, while, foreach. For your purpose it is foreach.
Start with the array dimension, Array can be multi-dimension, Like you have multi-dimension. If you have an array like below, then it is single dimension.
array(
key => value,
key2 => value2,
key3 => value3,
...
)
Now, How can you know what is a multi-dimension array, If you array has another array as child then it is called multi-dimensional array, like below.
$array = array(
"foo" => "bar",
42 => 24,
"multi" => array(
"dimensional" => array(
"array" => "foo"
)
)
);
Its time to work with your array. Suppose you want to access the value of company_name, what should you do?? Let your array name is $arr.
First you need to use a foreach loop like:
foreach($arr as $key => $val)
The keys are (meta, companies, total_companies...), they are in the first dimension. Now check if the key is company_name or not, if it matches than you got it. Or else you need to make another loop if the $val is an array, You can check it using is_array.
By the same processing at the last element your loop executes and find your value.
Learning
Always a good idea to start with the docs:
arrays: http://php.net/manual/en/language.types.array.php
foreach: http://php.net/manual/en/control-structures.foreach.php
As for tutorials, try the interactive tutorial over at codecademy: https://www.codecademy.com/learn/php
Unit 4 has a tutorial on arrays
Unit 11 has a lesson on advanced arrays.
Your code
As for your code, look at the following which I will show you your array structure and how to access each element. Perhaps that will make things clearer for you.
So lets say your array is named $myArray, see how to access each part via the comments. Keep in mind this is not php code, I'm just showing you how to access the array's different elements.
$myArray = Array
(
// $myArray['meta']
[meta] => Array (
// $myArray['meta']['total_record_count']
[total_record_count] => 1
// $myArray['meta']['total_pages']
[total_pages] => 1
// $myArray['meta']['current_page']
[current_page] => 1
// $myArray['meta']['per_page']
[per_page] => 1
)
// $myArray['companies']
[companies] => Array (
// $myArray['companies'][0]
[0] => Array (
// $myArray['companies'][0]['id']
[id] => 291869
// $myArray['companies'][0]['url']
[url] => https://api.mattermark.com/companies/291869
// $myArray['companies'][0]['company_name']
[company_name] => gohenry.co.uk
// $myArray['companies'][0]['domain']
[domain] => gohenry.co.uk
)
)
// $myArray['total_companies']
[total_companies] => 1
// $myArray['page']
[page] => 1
// $myArray['per_page']
[per_page] => 1
)
As for your for each loop
foreach($jsonObj as $item)
{
echo $item['total_companies'];
}
What the foreach loop is doing is looping through each first level of the array $jsonObj, so that would include:
meta
companies
total_companies
page
per_page
Then within the curly braces {} of the foreach loop you can refer to each level by the variable $item.
So depending on what you want to achieve you need to perhaps change your code, what is it you're trying to do as it's not really clear to me.
As for the code within the loop:
echo $item['total_companies'];
It won't work because you're trying to access an array with the index of total_companies within the first level of the $jsonObj array which doesn't exist. For it to work your array would have to look like this:
$jsonObj = array (
'0' => array ( // this is what is reference to as $item
'total_companies' => 'some value'
)
)
What you want to do is this:
foreach($jsonObj as $item)
{
echo $jsonObj['total_companies'];
}
As for your final snippet of code:
echo $item[0]['total_companies'];
Answered this above. Access it like $jsonObj['total_companies'];
echo $item['companies'][0]['id'];
If you want to loop through the companies try this:
foreach($jsonObj['companies'] as $item)
{
// now item will represent each iterable element in $jsonObj['companies]
// so we could do this:
echo $item['id'];
}
I hope that all helps! If you don't understand please make a comment and I'll update my answer.
Please take a look in to here and here
Information about php arrays
Try recursive array printing using this function:
function recursive($array){
foreach($array as $key => $value){
//If $value is an array.
if(is_array($value)){
//We need to loop through it.
recursive($value);
} else{
//It is not an array, so print it out.
echo $value, '<br>';
}
}
}
if you know how deep your array structure you can perform nested foreach loop and before every loop you have to check is_array($array_variable), like :
foreach($parent as $son)
{
if(is_array($son))
{
foreach($son as $grandson)
{
if(is_array($son))
{
foreach($grandson as $grandgrandson)
{
.....
......
.......
}
else
echo $grandson;
}
else
echo $parent;
}
else
echo $son;
}
hope it will help you to understand
I have and array that is being produced from a webservice.
Array (
[TPA_Extensions] => Array (
[TPARoomDetail] => Array (
[GuestCounts] => Array (
[GuestCount] => Array (
[!AgeQualifyingCode] => 10
[!Count] => 1
)
)
[!Occupancy] => Single
[!OccupancyCode] => SGL
)
)
[!IsRoom] => true
[!Quantity] => 1
[!RoomType] => Palace Gold Club Room
[!RoomTypeCode] => PGC
)
My foreach loop is as below
foreach ($roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"] as $guestcount) {
echo "guest count1->";print_r($guestcount);
echo "guest count2->"; print_r($roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"]);
}
The output i get is
guest
count1->10 guest count2->Array ( [!AgeQualifyingCode] => 10 [!Count] => 1 )
guest count1 should have been an array
Array ( [!AgeQualifyingCode] => 10 [!Count] => 1 ) but it comes as an int 10 ..
why is that so ..?
Your output is correct, $guestcount holds the number '10',
where $roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"]
hold an array.
this is your loop:
foreach ($roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"] as $guestcount) {
echo "guest count1->";print_r($guestcount);
echo "guest count2->"; print_r($roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"]);
}
ths loop will run 2 times, because that's the number of childs in GuestCount array.
it will be '10', then '1', exactly reflecting the structure of your array:
[!AgeQualifyingCode] => 10
[!Count] => 1
Theres nothing wrong in the code as 1st index holds integer value and 2nd index holds array. However your method of accessing array value are very complicated and doesn't looks good. You an access the array values and keys in more effective manner as follows.
1)Create a method that takes path of the array you want to access
For example According to your code if I want to access AgeQualifyingCode key than I have to write $roomType["TPA_Extensions"]["TPARoomDetail"]["GuestCounts"]["GuestCount"]["AgeQualifyingCode"].
This doesn't looks good, wouldn't it be great if you just have to pass the path of key you want to access the value to.
For example: /TPA_Extensions/TPARoomDetail/GuestCounts/GuestCount/AgeQualifyingCode
You just have to define a function that takes the path of the key, and will return value for that key
<?php
function path($path=null){
if($path){
$array = $theNameOfOriginalArray
$path = explode('/',$path);
foreach($path as $sub){
if(isset($array[$sub])){
$array = $array[$sub];
}
}
return $array;
}
}
$value = path('TPA_Extensions/TPARoomDetail/GuestCounts/GuestCount/AgeQualifyingCode');
//will return 10
?>
I am new to php and still learning the language,
let say I have two array
For Example
Array
(
[house_id] => 6
[name] => Lake Villa
[floor] => 5
[unit] => 25
)
Array
(
[house_id] => 6
[name] => Lake Villa
[floor] => 5
[unit] => 25
[parking_id] => 9
[resident_count] => 4
)
How do i get the keys of 1st array onto second, what i am saying is, i just need house_id, name, floor, unit from second array and discard rest of the information.
However, they key is not same and dynamic, which means the first array key whatever returned is also present on second but with additional information. The information above is just an example and the keys might varies but whatever key on first array contains on second array too.
I tried this, but isn't working:
foreach($arr1 as $k=>$v) {
foreach($arr2 as $j=>$w) {
if(isset($arr2[$k]))
$arr[$k] = $w;
}
}
You could use array_intersect_key, to merge the arrays.
$newArray = array_intersect_key($array2, $array1);
Use array_intersect_key().
array_intersect_key() returns an array containing all the entries of
array1 which have keys that are present in all the arguments.
Code
var_dump(array_intersect_key($array1, $array2));
foreach($arr2 as $key=>$val){
if(!array_key_exists($key,$arr1))
unset($arr2[$key]);
}
change condition from
if(isset($arr2[$k]))
to
if($arr1[$k] == $arr2[$j]) // it will work.
and isset is used for checking the variable is set or not.
Try this:
foreach($arr2 as $k=>$v) {
//Check if key is in first array
if(!isset($arr1[$k])) {
//Key not in first array, remove from second array.
unset($arr2[$k]);
}
}
try this
$result_array = array_intersect_key($arr2, $arr1);
I am pulling some data from a mysql table via the following:
$result = mysql_query("SELECT characters_ID, name, borndate, deathdate, marrieddate, ispregnant FROM characters WHERE isfemale='1'",$db);
$femaledata = array();
while ($row_user = mysql_fetch_assoc($result))
$femaledata[] = $row_user;
This gives me an array that looks like this:
Array (
[0] => Array ( [characters_ID] => 2 [name] => Helene [borndate] => 35 [deathdate] => 431 [marrieddate] => 157 [ispregnant] => 0 )
[1] => Array ( [characters_ID] => 4 [name] => Isabelle [borndate] => 161 [deathdate] => [marrieddate] => 303 [ispregnant] => 1 )
[2] => Array ( [characters_ID] => 7 [name] => Helene [borndate] => 326 [deathdate] => [marrieddate] => [ispregnant] => 0 )
[3] => Array ( [characters_ID] => 72 [name] => Faylinn [borndate] => 335 [deathdate] => [marrieddate] => [ispregnant] => 0 )
[4] => Array ( [characters_ID] => 74 [name] => Relina [borndate] => 349 [deathdate] => [marrieddate] => [ispregnant] => 0 )
)
Now I need to remove any characters who have a value for deathdate or ispregnant, and then I need to run some code on the others. For instance I need to grab the borndate value, compare it to the current date to find age, and based partly on age, I need to run code for each to determine if the character has become pregnant on the turn.
Apologies that this seems like a long-reaching question. Multidimensional arrays still seem to confound me.
Edit: (question needs to be more clear)
Can you please suggest the best way that I would either explode or break up the array, and then do conditional modification to the data, or instead how I could remove unneeded data and then do conditional modification to the data.
My ultimate output here would be taking suitable female characters (not dead or pregnant already), and based on their age, giving them a chance at becoming pregnant. If true, I'd throw some code back at the SQL database to update that character.
Thanks!
All the things you need could probably get done with SQL :
Now I need to remove any characters who have a value for deathdate or
ispregnant
Simply add some argument to your WHERE condition :
isPregnant IS NULL AND deathdate IS NULL
For instance I need to grab the borndate value, compare it to the
current date to find age
Depending of your field format the maths could be done in SQL , have look to the DATE function of mysql
Don't underestimate the power of your sql server , 99% of the time it is probably faster than php to work on data set.
Instead if immediately removing some rows from your array, try limiting the data you recieve through SQL.
You can loop through your array like this:
foreach($femaledata as $female)
{
echo $female['name'];
}
do you mean something like this?
$femaledata = array();
while ($row_user = mysql_fetch_assoc($result)) {
$ok = false;
// do you validation for every user
if($ok) array_push($femaledata,$row_user);
}
TJHeuvel gave you the right answer, and you should accept that answer. However, to inform: multidimensional arrays need not confound. Let me see if I can explain.
In PHP, you can put any object at all into an array, including other arrays. So, let's say you have an array that contains other arrays. When you iterate over that array using a looping construct (usually a foreach loop), each iteration of the loop will give you another array; if you want to access the elements of this sub-array, just loop over it. This is called a nested loop. Example:
$r = array(
array(1,2,3),
array(4,5,6),
array(7,8,9)
);
foreach ($r as $cur) {
foreach ($cur as $num) {
echo $num;
}
}
In each iteration of the outer loop, $cur contains an array; the inner loop iterates over contents of this array. This technique allows you to process arrays of any dimension.
However, in your specific case, you don't need to use an inner loop to iterate over your subarrays. You only need to access certain elements of your subarrays by their keys, rather that processing all of them in turn. So, a simple foreach loop will do.
