使用一维数组，将其展开，并创建一个多维数组

Question

So I have an array that looks like this:

Array
 (
  [0] => [e-mail]:John
  [1] => [e-mail]:Jane
)

As you can see, it's user'semail and user's name, seperated by a colon.

I want to create a multi dimensional array, that explodes the colon, and then will create a multi dimensional array that would look more like

Array
 (
   [0] => Array
    (
        [user_email] => [e-mail]
        [user_name] => John
    )

   [1] => Array
    (
        [user_email] => [e-mail]
        [user_name] => Jane
    )

)

Answer 1

You can do it like:

<?php

$data = [
    "[e-mail]:John",
    "[e-mail]:Jane"
];

function customArray($data){
    $final = [];
    $i = 0;

    foreach($data as $k => $v){
        $splitted = explode(":",$v);
        $final[$i]['user_email'] = $splitted[0];
        $final[$i]['user_name']  = $splitted[1];
        $i++;
    }

    return $final;
}

print_r(customArray($data));

See the results here. Basically what I do above is

• iterate over the array,
• explode the value by the delimiter :,
• index them within the iteration using the same [$i] so that the new key/value is paired correctly per original array element.

Do properly name things though, I'm just giving an example :-)
