I have the following array that I need to use in a laravel email view template
$inputs['test']
Which looks like this when I dd($inputs['test']);
Array:1[
"order" => array:2[
0 => 523
1 => 522
]
]
I've tried this in my foreach loop but it doesn't work
foreach($inputs['test']->order as $test){
echo $test;}
What syntax would I need to echo each value from the order nested array?
You use square braces [] to access array values, arrows -> to access properties on objects
foreach($inputs['test']['order'] as $test){
echo $test;
}
You have to use array not object loop:
foreach($inputs['test']['order'] as $test){
echo $test;
}
Simply use the helper method for Arr facade and avoid all these complications.
For instance, if you've something like
$array = ['products' => ['desk' => ['price' => 100]]];
You can do this
return Arr::get($array, 'products.desk.price');
and it will return 100. The best part is if the key price doesn't exist, it doesn't throw and error.
So, if the array had to be like this
$array = ['products' => ['desk' => []];
and you did this
return Arr::get($array, 'products.desk.price');
It would return null and not any error even though the item doesn't exist. You can also set a default value if you want like this
return Arr::get($array, 'products.desk.price', 2);
This would return 2 if the price doesn't exist. https://laravel.com/docs/8.x/helpers#method-array-get
use Illuminate\Support\Arr; if neededTry
$inputs['test']['order'][0]
Basically, php reads the nested arrays as arrays in arrays .. so no matter how many arrays nested you can always use [][][][][]
<?php
$array = array(
"foo" => "bar",
42 => 24,
"multi" => array(
"dimensional" => array(
"array" => "foo"
)
)
);
var_dump($array["foo"]);
var_dump($array[42]);
var_dump($array["multi"]["dimensional"]["array"]);
?>
and you can use it in looping as such
foreach($inputs['test']['order'] as $test){
echo $test;}
First you have what is key and what is value of arrays
They are multiple ways to echo arrays this is one way
foreach($inputs['test']['order'] as $key => $test){
echo 'Key ->'.$key.'<br/>';
echo 'Value ->'. $test. '<br/>';
}
$myEcho = function($x){
if(is_array($x)){foreach($x as $one){$myEcho($one);}
}else{ echo $x; }
};
array_map($myEcho, $inputs['test']['order']);
data_get($mainArrayName, '.nestedArrayName..NestedArrayKeyName');
try it..hope this work No need a foreach here
data_get() is not an existing core PHP function.
