PHP manipulate array of string into an associative array

Question

I have an array like this:

array(4) {

  [0] => "1. \Device\NPF_{1AAAAA99-7933-4CBC-AF26-2A1C1394BD94} (VirtualBox Host-Only Network)"

  [1] => "2. \Device\NPF_{2BBBBB88-75BB-4CD0-970A-36430287C245} (Wireless Network Connection 6)"

  [2] => "3. \Device\NPF_{3CCCCC77-8469-4445-A2ED-9C0FDDBA1C3D} (Wireless Network Connection 7)"

  [3] => "4. \Device\NPF_{4EEEEE66-2C9D-4D47-B7EA-8A20A40A149B} (Local Area Connection)"

}

and would like to manipulate into a new associative array like this:

array(4) {

  ["1"] => "VirtualBox Host-Only Network"

  ["2"] => "Wireless Network Connection 6"

  ["3"] => "Wireless Network Connection 7"

  ["4"] => "Local Area Connection"

}

I realise that I could use a foreach loop to go thru the original array then in each iteration use substr function to get the first char for the new array key and to look for the sentence inside the () pattern but failed to implement this. Any suggestion is much appreciated! Thanks!

You should post the code that you have tried.

In php you can do that without loops:

$data = [
    "1. \Device\NPF_{1AAAAA99-7933-4CBC-AF26-2A1C1394BD94} (VirtualBox Host-Only Network)",
    "2. \Device\NPF_{2BBBBB88-75BB-4CD0-970A-36430287C245} (Wireless Network Connection 6)",
    "3. \Device\NPF_{3CCCCC77-8469-4445-A2ED-9C0FDDBA1C3D} (Wireless Network Connection 7)",
    "4. \Device\NPF_{4EEEEE66-2C9D-4D47-B7EA-8A20A40A149B} (Local Area Connection)",
    ];

$names = array_combine(
    preg_replace('~\D.*~', '', $data),
    preg_replace('~.*\((.+?)\)$~', '$1', $data));

print_r($names);

Result:

Array
(
    [1] => VirtualBox Host-Only Network
    [2] => Wireless Network Connection 6
    [3] => Wireless Network Connection 7
    [4] => Local Area Connection
)

Wow, that is fast! However, what I need is the final array key came from the first charater of the original array (e.g. the 1. 2. 3. 4.). Could I achieve that with your approach? Many many thanks!

Wow, work of a magician! After going through all the answers, I am amazed by the true power of regular expression and preg_match. My next topic of study. Again, thank you trully, everyone!

Your code should look something like this,

<?php
$items_extended = array("1. \\Device\\NPF_{1AAAAA99-7933-4CBC-AF26-2A1C1394BD94} (VirtualBox Host-Only Network)", 
"2. \\Device\\NPF_{2BBBBB88-75BB-4CD0-970A-36430287C245} (Wireless Network Connection 6)", 
"3. \\Device\\NPF_{3CCCCC77-8469-4445-A2ED-9C0FDDBA1C3D} (Wireless Network Connection 7)", 
"4. \\Device\\NPF_{4EEEEE66-2C9D-4D47-B7EA-8A20A40A149B} (Local Area Connection)");
$items = array();
foreach($items_extended as $key => $value){
    preg_match('#\((.*?)\)#', $value, $match);
    $items[($key + 1)] = $match[0];
}
?>

Try to use that code : by using foreach, it should work. To test regex : http://www.phpliveregex.com/

<? 
var $arrInputs = array (......); // you put your array with data

var $arrest = [];
foreach ($arrInputs as $key => $input_line ){

preg_match("(^.).*[(](.*)[)]$", $input_line, $output_array);

$arrest[$output_array[1]] = $output_array[2];

}

print_r($arrest);
