Split array to create an associative array - php

Question

I have an array that looks like this:
a 12 34
b 12345
c 123456
So the array looks like
$array[0] = "a 12 34"
$array[1] = "b 12345"
$array[2] = "c 123456"
I am trying to create an associative array such that
[a] => 12 34
[b] => 12345
[c] => 123456
Can I possibly split the array into two, one for containing "a, b, c" and another for their contents and use the array_combine()? Or are there any other ways?

Answer 1

You can do that within a loop like the snippet below demonstrates. Quick-Test here:
$array = array("a 12 34", "b 12345", "c 123456");
$array2 = array();
foreach($array as $data){
preg_match("#([a-z])(\s)(.*)#i", $data, $matches);
list(, $key, $space, $value) = $matches;
$array2[$key] = $value;
}
var_dump($array2);
// YIELDS::
array(3) {
["a"]=> string(5) "12 34"
["b"]=> string(5) "12345"
["c"]=> string(6) "123456"
}
Or using a Blend of array_walk() and array_combine() which can be Quick-Tested Here.
<?php
$array = array("a 12 34", "b 12345", "c 123456");
$keys = array();
array_walk($array, function(&$data, $key) use (&$keys){
$keys[] = trim(preg_replace('#(\s.*)#i', '', $data));;
$data = trim(preg_replace('#(^[a-z])#i', '', $data));
});
$array = array_combine($keys, $array);
var_dump($array);;
// YIELDS::
array(3) {
["a"]=> string(5) "12 34"
["b"]=> string(5) "12345"
["c"]=> string(6) "123456"
}

Answer 2

You can do it without any difficulty :) A simple loop is possible to do it.
Create new array
Lopp on each row
Split each data (explode(' ', $row, 2), strstr, substr, ...) ?
Put data on your new array $array[$key] = $value;

Answer 3

You could use a combination of array_map, array_column and array_combine:
$array = array_map(function ($v) { return explode(' ', $v, 2); }, $array);
$array = array_combine(array_column($array, 0), array_column($array, 1));
