I have this json file: and I would like to get all the title so my code is: var_dump($json['results'][0]['title']); but it getting just one title, I know I need to do a foreach but I don't know how :( so if you could help me that will be great ! Thanks
Your data is coming back as an array with item's inside of it. This mean's you'll need to loop through this JSON and print each item;
foreach($json['results'] as $movie) {
echo $movie['title'] . "<br />";
}
You will want to loop through all of the JSON results objects and echo or store the 'title' value;
foreach ($json['results'] as $object) {
//Option 1
echo $object['title'];
//Option 2
array_push($titles, $object['title'];
}
Assuming that the variable $json contains your data, I see two equivalent options in order to iterate trough the array
Using for
for($index = 0; $index < count($json['results']); $index++) {
echo $json['results'][$index]['title'] . "\n";
}
Using foreach
foreach($json['results'] as $movie) {
echo $movie['title'] . "\n";
}

Hey i have five json from all getting information now i encountered with problem like this -> from five different json i need to get latest videoId who newer shows first and all it need put to one function foreach for my too hard i try it do about 5hours and stay in same step
Json 1 json 2
All code need from this two json get latest(newest) videoId in one foreach echo
<?php
$videoList1 = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCKLObxxmmAN4bBXdRtdqEJA&maxResults=50&key=AIzaSyDVTF2abNVa5pRitb8MVz1ceJFhE-2y_qk'));
$videoList2 = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCynfZM0Edr9cA4pDymb2rEA&maxResults=50&key=AIzaSyDVTF2abNVa5pRitb8MVz1ceJFhE-2y_qk'));
$i = 0;
foreach($videoList1->items as $item){
if(isset($item->id->videoId)) {
echo $item->id->videoId;
if ( ++$i > 3) {
break;
}
}
}
Tray this:
$videoList1 = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCKLObxxmmAN4bBXdRtdqEJA&maxResults=50&key=AIzaSyDVTF2abNVa5pRitb8MVz1ceJFhE-2y_qk'),true);
$videoList2 = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/search?order=date&part=snippet&channelId=UCynfZM0Edr9cA4pDymb2rEA&maxResults=50&key=AIzaSyDVTF2abNVa5pRitb8MVz1ceJFhE-2y_qk'),true);
$videoList = array_merge($videoList1["items"],$videoList2["items"]);
/// sort lastet first
foreach ($videoList as $key => $part) {
$sort[$key] = strtotime($part['snippet']['publishedAt']);
}
array_multisort($sort, SORT_DESC, $videoList);
foreach ($videoList as $video) {
if(isset($video["id"]["videoId"])) {
echo 'publishedAt: '. $video['snippet']['publishedAt'] . ' VideoID: ' . $video["id"]["videoId"] . "\n </br>";
}
}
So I would like to create just one loop to parse the json data i have. I can successfully parse it in 2 foreach loops however when trying to combine in one loop using $key => $value the $key returns nothing when called. How can I successfully take the 2 foreach loops I have here and combine them into one?
$contents = file_get_contents($url);
$results = json_decode($contents, true);
$jsonList = $results['genres'];
foreach($jsonList as $key) {
$GenreID = $key['id'].'<br>';
echo $GenreID;
}
foreach($jsonList as $key => $value) {
$GenreName = $value['name'].'<br><br>';
echo $GenreName;
}
The json data is as follows:
{"genres":[{"id":28,"name":"Action"},{"id":12,"name":"Adventure"},{"id":16,"name":"Animation"},{"id":35,"name":"Comedy"},{"id":80,"name":"Crime"},{"id":99,"name":"Documentary"},{"id":18,"name":"Drama"},{"id":10751,"name":"Family"},{"id":14,"name":"Fantasy"},{"id":36,"name":"History"},{"id":27,"name":"Horror"},{"id":10402,"name":"Music"},{"id":9648,"name":"Mystery"},{"id":10749,"name":"Romance"},{"id":878,"name":"Science Fiction"},{"id":10770,"name":"TV Movie"},{"id":53,"name":"Thriller"},{"id":10752,"name":"War"},{"id":37,"name":"Western"}]}
You can still use $key as an index when also extracting the $value.
However note that you shouldn't be assigning the line breaks to your variables, and should instead consider them part of the view by echoing them out independently:
$contents = file_get_contents($url);
$results = json_decode($contents, true);
$jsonList = $results['genres'];
foreach($jsonList as $key => $value) {
$GenreID = $key['id']; // Depending on structure, you may need $value['id'];
$GenreName = $value['name'];
echo $GenreID . '<br>';
echo $GenreName . '<br><br>';
}
Your single loop below here.
foreach($jsonList as $key)
{
$GenreID = $key['id'].'<br>';
echo $GenreID;
$GenreName = $value['name'].'<br><br>';
echo $GenreName;
}
$key is a assosative array.Therefore it had some index.So you can use this index in single loop.
It seems you get confused over your data structure. Seeing the json, the resulting "$jsonlist" supposed to contain array with id and value as keys.
You can iterate over it and extract the the appropriate key.
Myabe something like this:
foreach($jsonlist as $value) {
echo "id: " . $value['id'] . "\n";
echo "name: " . $value['name'] . "\n";
}
extra bonus, if you want to create 1 level array from your json based on id with the name you could try array reduce using anon function like this:
$jsonlist = array_reduce($jsonlist, function($result, $item){
$result[$item['id']] = $item['name'];
return $result;
}, []);
extra neat for transformation of static structure data.
I want to change the value of the $key because I have array_splice inside the loop which change the position of my values so - it mess up the value I need in a specific place.
I tried $key-- but it doesn't work.
for example when I print the $key after I do echo $key it's fine but when I echo $key just after the foreach loop I get the worng value.
Any ideas?
foreach ($cut as $key => $value) {
echo "foreach key:".$key."<br>";
if(in_array($value,$operators))
{
if($value == '||')
{
echo "found || in position:".$key."<br>";
if(($key+1<sizeof($cut)))
{
$multi = new multi;
echo "<br>"."key-1: ";
print_r($cut[$key-1]);
echo"<br>";
echo "<br>"."key+1: ";
print_r($cut[$key+1]);
echo"<br>";
$res = $multi->orex($cut[$key-1],$cut[$key+1],$numString);
$cut[$key-1]= $res;
array_splice($cut,$key,1);
array_splice($cut,$key,1);
$key--; //here trying to change the key
echo "new string:";
print_r($cut);
echo "<br>";
echo "key:".$key."<br>";
}
}
}
}

I don't think it is a good idea to change the array itself inside the foreach loop. So please crete another array and fill data into it, which will be your result array. This method works well when your array data is not big, in other words, most situations.

I don't know what do you mean. Let me give it a guess...
You want:
foreach($arr as $key=>$val){
$newkey = /* what new key do you want? */
$arr[$newkey] = $arr[$key];
unset($arr[$key]);
}
i have fetched a json output for menus to be displayed in the webpage.
I want to convert it into menus and sub menus. I have tried looping through it but it doesnt works.Please help me with this, thanks in advance.
$output = json_encode(array($menu_main_row['menu_name'] => $sub_menu));
Json Output:
{"Home":"[{\"Create\":\"create.php\"},{\"Edit\":\"edit.php\"}]"}
{"Projects":"[{\"My Projects\":\"myprojects.php\"},{\"My reports\":\"reports.php\"}]"}
This is the foreach loop which i used.
foreach($value as $main_menu_name=>$arr_val_sub)
{
echo "<ul>";
echo $main_menu_name;
$val=json_decode($arr_val_sub);
foreach ($val as $menu_name=>$menu_url)
{
echo $menu_name;
echo "<br>";
echo $menu_url;
}
}
The main menu name is printing, but when i print the sub menu name and url it prints like 0 1 .
You missed another step to dig into the json. $menu_url is another json to parse. Below code fixes it
foreach($value as $main_menu_name=>$arr_val_sub)
{
echo "<ul>";
echo $main_menu_name;
$val=json_decode($arr_val_sub);
foreach ($val as $menu_name=>$menu_url)
{
$submenu=new RecursiveArrayIterator($menu_url);
foreach ($submenu as $submenu_name=>$submenu_url)
{
echo $submenu_name;
echo "<br>";
echo $submenu_url;
echo "<br>";
}
}
}
After searching for an answer in this forum I found only related questions but under other context that would not apply to my case. Here's my problem:
I have a 3-dim array defined in a function like this:
$m_Array[h][$family][$iterator]
the values for
$family range from 6-10;
$iterator from 0-3 but has duplicates (0,1,2,3,1),
and the $m_Array results in values (25,26,30,31,33).
I am unable to echo the result using those indices to get these results once returned from the function.
NOTE: I was able to echo when I had 2-dim $m_Array[h][$iterator] but could not use it because the last value for the iterator would replace the second in the array.
Since I was able to echo the 2-dim, this is not a question on getting the return from the function or iterate over the indices.
Thanks.
Use print_r($arrayName) to print an array. You cannot echo an Array or Object
as others mentioned, you can use var_dump() or print_r(). If you need to access each item then you're going to need nested loops.
foreach($m_Array as $i => $h)
{
//echo $i, $key for h
foreach($h as $j => $family)
{
//echo $j, key for family
foreach($family as $k => $iterator)
{
echo $iterator;
}
}
}
try this:
$keys = array_keys($h);
for($i = 0; $i < count($h); $i++) {
echo $keys[$i] . "{<br>";
foreach($h[$keys[$i]] as $key => $value) {
echo $key . " : " . $value . "<br>";
}
echo "}<br>";
}
It prints all values and keys
