Loop through PHP multidimensional array - php

Question

I am trying to loop through a multidimensional array but in the foreach loop it just outputs error
index 'name' not found. index 'calories' not founder
foreach($responsex['foods'] as $fx5)
{
echo($fx5['name']);
echo($fx5['calories']);
}
Response: i.e. $responsex
array ( 'encodedId' => '4H8xxx', 'displayName' => 'sam', )array(3) {
["foods"]=> array(3) { [0]=> array(5) { ["isFavorite"]=> bool(false)

Answer 1

you can recursively iterate through the arrays and print them as follows as key value pairs.
<?php
//initially call the function
print_array($responsex);
function print_array($array){
foreach($array as $key=>$value){
//recursively print the array
if(is_array($value)){
echo("Array : ".$key."\n");
print_array($value);
}
else{
echo($key." => ".$value);
}
}
}
?>
You can define additional tasks other than printing them with the above code.
Edit:
if you are sure that the array is two dimensional, no need to go recursively.
<?php
//initially call the function
print_array($responsex);
//if you are sure that the array is two dimensional, no need to go recursively.
function print_array($array){
foreach($array as $key=>$value){
if(is_array($value)){
if($key==="foods"){
var_dump($array[$key]);
}
}
else{
echo($key." => ".$value);
}
}
}

Answer 2

Use this way..
<?php
$keys = array_keys($data);// put your array name as a place of $data
$iterations = count($array[$keys[0]]);
for($i = 0; $i < $iterations; $i++) {
$data = array();
foreach($array as $key => $value) {
$data[$key] = $value[$i];
}
print_r($data);
}
?>
