I'm from Perl but I'm beginner in PHP. I'm having following array
$rating_data = Array ("51" => Array (5,3,4,2));
I'm trying to access the each data using loop so I tried following
foreach ($keys as $rating_data)
{
foreach ($index as $rating_data[$keys])
{
echo "$index";
}
}
But the above one is not working. I have also tried the below one also,
$all_keys = array_keys($rating_data);
foreach ($keys as $all_keys)
{
foreach ($values as $all_keys)
{
echo "$values";
}
}
But I didn't get the output. It works if I hard code the keys like below:
$rating_data["51"][0];
How to fix this issue.?
You can get the key position and iter value ( sencod level ).
foreach($rating_data as $key => $values)
{
echo $key; // Output "51"
foreach($values as $value)
{
echo $value; // Output: iter1: "5", iter2: "3", iter3: "4", iter1: "2",
}
}
It should be as simple as below:
foreach($rating_data as $key => $values) {
echo $key;
foreach($values as $value) {
echo $value;
}
}
You seem to have your parameters the wrong way around in your foreach statements. I would advise a quick read through the foreach docs.

So here's the thing, I get this json from a url ( in my context i get it from a url, but let's say here I write my json in a variable :
$file = '[
{"status": "5.4.1","email": "dddddd#exelcia-it.com"},
{"status": "5.4.1",, "email": "sksksksk#exelcia-it.com"}
]'
Then I do $json = json_decode($file,true);
And I want to get all the emails so I do :
foreach ($json as $key => $value) {
echo $value["email"]. "<br>";
}
But what I also need, is to return something like that from the loop (only for one property):
"email = dddddd#exelcia-it.com".
So I need to also get the name of the property but I can't figure this out.
I tried
foreach($json as $key => $propName){
echo $key.'<br>';
}
But I just get the index (0,1,...), not what I want.
Thanks!
You have to loop each json row, this should works:
$file = '[{"status": "5.4.1","email": "dddddd#exelcia-it.com"},{"status": "5.4.1", "email": "sksksksk#exelcia-it.com"}]';
$json = json_decode($file,true);
foreach($json as $row)
{
foreach($row as $key => $value)
{
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
Use this loop to get key and value pairs together.
foreach($data as $row)
{
foreach($row as $key => $val)
{
echo $key . ': ' . $val;
echo '<br>';
}
}
Ok thanks that's what I needed !
For me I just need the email properties and values, so I do :
foreach($json as $row)
{
foreach($row as $key => $value)
{
if($key=='email'){
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
}
Awesome ! thanks !
Below is a simple array that I created:
$colors = array(
"parent1" =>array(
"item1"=>"red",
"item2"=>"green",
"item3"=>"blue",
"item4"=>"yellow"
),
"parent2" =>array(
"item1"=>"red",
"item2"=>"green",
"item3"=>"blue",
"item4"=>"yellow"
)
);
What I need to get is the key of my level 1 arrays which are string "parent1" and "parent2".
Currently I'm using foreach with while loop to get the key
foreach ($colors as $valuep) {
while (list($key, $value) = each($colors)) {
echo "$key<br />";
}
}
but I'm only able to get the "parent2" string from using the above method and not "parent1".
You're so close.
foreah($colors as $key => $val)
{
echo $key . "<br/>";
}
Use the key like so:
foreach ($colors as $key => $value) {
echo $key.'<br>';
}
To print out the keys:
foreach ($colors as $key => $value) {
echo $key . '<br />';
}
You can also get all of the keys from an array by using the array_keys() method, for example:
$keys = array_keys($colors);
foreach ($keys as $key) {
echo $key . '<br />';
}
I have an array that looks like this:
$array = array(
array(
"http://google.com",
"Google"
),
array(
"http://yahoo.com",
"Yahoo"
)
);
What is the simplest way to loop through it. Something like:
foreach ($array as $arr) {
// help
}
EDIT: How do I target keys, for example, I want to do:
foreach ($array as $arr) {
echo '<a href" $key1 ">';
echo ' $key2 </a>';
}
In order to echo out the bits you have to select their index in each array -
foreach($array as $arr){
echo ''.$arr[1].'';
}
Here is an example.
Use nested foreach() because it is 2D array. Example here
foreach($array as $key=>$val){
// Here $val is also array like ["Hello World 1 A","Hello World 1 B"], and so on
// And $key is index of $array array (ie,. 0, 1, ....)
foreach($val as $k=>$v){
// $v is string. "Hello World 1 A", "Hello World 1 B", ......
// And $k is $val array index (0, 1, ....)
echo $v . '<br />';
}
}
In first foreach() $val is also an array. So a nested foreach() is used. In second foreach() $v is string.
Updated according to your demand
foreach($array as $val){
echo ''.$val[1].'';
}
The easiest way to loop through it is:
foreach ($array as $arr) {
foreach ($arr as $index=>$value) {
echo $value;
}
}
EDIT:
If you know that your array will have always only two indexes then you can try this:
foreach ($array as $arr) {
echo "<a href='$arr[0]'>$arr[1]</a>";
}
First modify your variable like this:
$array = array(
array("url"=>"http://google.com",
"name"=>"Google"
),
array("url"=>"http://yahoo.com",
"name"=>"Yahoo"
));
then you can loop like this:
foreach ($array as $value)
{
echo '<a href='.$value["url"].'>'.$value["name"].'</a>'
}
The way to loop through is,
foreach($array as $arr)
foreach($arr as $string) {
//perform any action using $string
}
Use the first foreach loop without { } for the simplest use.
That can be the most simple method to use a nested array as per your request.
For your edited question.
Wrong declaration of array for using key.
$array = array(
"http://google.com" => "Google",
"http://yahoo.com" => "Yahoo" );
And then, use the following.
foreach ($array as $key => $value)
echo "<a href='{$key}'>{$value}</a>";
This doesn't slow down your server's performance.
In modern versions of php, you can assign (destructure) subarray values to variables of your choosing.
A good tutorial: https://stitcher.io/blog/array-destructuring-with-list-in-php
Code: (Demo)
$array = [
["http://example1.com", "Example 1"],
["http://example2.com", "Example 2"]
];
foreach ($array as [$key1, $key2]) {
echo "$key2\n";
}
Output:
Example 1
Example 2
To be honest, I'd probably name the variables $url and $text respectively.
I want to use a multidimensional array in different functions.so i am making it as a global variable(array).i created a multidimensional array and made it as global to access in different function.now how can i get the values from it using foreach loop?
here is my code
$test=array(
array(
"input1"=>"v1",
"input2"=>"v2"),
array(
"input3"=>"v3",
"input4"=>"v4")
);
class testing
{
function testp()
{
global $test;
foreach($test as $key => $value)
{
echo $value;
}
var_dump($test);
echo is_array($test);
}
}
$obj = new testing();
$obj->testp();
i used is_array and var_dump to confirm whether its an array.
all are fine
and its shwoing Error suppression ignored. now how can i get the values from it?
It is array of arrays, what works for top order array, works further as well:
foreach($test as $key => $value)
{
foreach($value as $k => $v){
echo $v;
}
}
This will echo your values v1, v2, v3, v4 one after another.
More general answer:
public function visitArray($test)
{
foreach($test as $key=>$value)
{
if(is_array($value))
{
visitArray($value);
}
else
{
echo $value;
}
}
}
Edit
Don't know why you're looping over keys and values, if key isn't took into account
More easy & simple way to access array values within a array.
foreach($test as $array_value){
if(is_array($array_value)) {
foreach ($array_value as $value) {
echo $value.'<br>';
}
}
}
I am trying to create a foreach that will go through some variables within an object.
At the moment it is just
class jabroni
{
var $name = "The Rock";
var $phrases = array ("The rock says", "Im gonna put the smackdown on you", "Bring it on jabroni");
var $moves = array ("Clothes line", "Pile driver", "Reverse flip");
}
I tried doing this:
$jabroni = new jabroni()
foreach ($jabroni as $value)
{
echo $value->phrases;
echo $value->moves;
}
However nothing gets printed.
Any ideas if what I am trying to achieve is possible, I have that gut feeling that its not and that I will have to just do individual foreach statements for each object member variable that is an area?
Thanks for your time!
You are doing wrong the loop.. You have one object, not an array of objects. so the correct way should be..
$jabroni = new jabroni();
foreach ($jabroni->phrases as $value)
{
echo $value;
}
foreach ($jabroni->moves as $value)
{
echo $value;
}
foreach ($jabroni->phrases as $value) {
echo $value;
}
foreach ($jabroni->moves as $value) {
echo $value;
}
You can do it in nested foreach loops. This will be easy instead of going for two for loops seperatley
foreach ($jabroni as $keys => $values)
{
if ($keys == 'phrases' || $keys == 'moves') {
foreach ($values as $value) {
echo $value;
}
}
}
