在3个变量中列出数组

I am noob in php and i need help for list this array in 3 variables.

Array ( [ram] => 2,3, [almacenamiento] => 16,32, [marca] => Huawey,Samsung, ) 

I want this :

$ram= "2,3,";

$almacenamiento="16,32,";

$marca="Huawey,Samsung,";

I only know list array simple with foreach()

print_r($_POST);

$result=$_POST;

foreach($result as $indice=>$valor){

    print"$indice";//INDICE
    print"$valor";//VALOR
}

You can just use $$ to create variables with the same name as the keys of the array, like this:

foreach($values as $key => $value) {
    $$key = $value;
}

If it is a keyed array you're using

$ram = $array['ram'];

If it is a $_POST variable (form submit, could also be a $_GET)

$ram = $_POST['ram'];

Use extract to pull out the variables from the array.

$arr = Array ( "ram" => "2,3" , "almacenamiento" => "16,32" , "marca" => "Huawey,Samsung");
Extract ($arr);

Echo $ram; // "2,3"

However I usually recommend keeping the values in the array and not extracting them.
Only in rare cases is there a point of extracting the variables.

you can use the extract() method, it will convert the array keys into values:

$arr = array ( "ram" => "2,3" , "almacenamiento" => "16,32" , "marca" => "Huawey,Samsung");

extract($arr);

echo $ram; //2,3
echo $almacenamiento; //16,32
echo $marca; //Huawey,Samsung

Here you can find more details about extract()

Here's another way that uses array destructuring (see here, too) and it works in PHP 7.1.10+:

<?php

[$ram,$almacenamiento, $marca ]= array_values(["ram" => "2,3", 
                                               "almacenamiento" => "16,32", 
                                               "marca" => "Huawey,Samsung"
                                               ]);
var_dump($ram,$almacenamiento, $marca);

see live code

One of the disadvantages of using array destructuring is that if one is not careful, one could overwrite a variable's value. The same may occur if you use extract(), unless you provide it the paramter EXTR_SKIP, as the following example illustrates:

<?php

$a = ["red"=>"rouge","blue"=>"sea","rally"=>"game","trolley"=>"SF"];


$red = "heifer";

extract($a, EXTR_SKIP);

echo "$red, $blue, $rally, $trolley
";

However, in Programming PHP by Rasmus Lerdorf et al (1st edition), one is advised to avoid potential variable conflict by using a parameter EXTR_PREFIX_SAME which affixes a user-specified prefix to extracted variables.

Lastly, you may automate generating multiple variables based on the array's values, using the list construct along with array_values(), as follows:

<?php

list($ram,$almacenamiento, $marca )= array_values(["ram" => "2,3", 
                                               "almacenamiento" => "16,32", 
                                               "marca" => "Huawey,Samsung"
                                               ]);
var_dump($ram,$almacenamiento,$marca);

With list(), one may also overwrite variables. So one should exercise care and test whether any variables already exist before using them with list(); see example here.
