I want to transfer
Array
(
[0] => name|smith
[1] => kid|tom
[2] => wife|emily
)
The fastest, smartest way into
Array
(
[name] => smith
[kid] => tom
[wife] => emily
)
It's not a big deal to use foreach for that. But I would prefer a smart one-liner.
try array_walk function:
$a = array
(
0 => 'name|smith',
1 => 'kid|tom',
2 => 'wife|emily'
);
$new_arr = array();
array_walk($a, function($v, $k) use(&$new_arr){
$arr = explode('|', $v);
$new_arr[$arr[0]] = $arr[1];
});
print_r($new_arr);
output
Array
(
[name] => smith
[kid] => tom
[wife] => emily
)
There are more than one ways to skin a cat.
Using array_reduce() (not in a single line, though):
$result = array_reduce(
$a,
function (array $carry, $item) {
list($key, $value) = explode('|', $item);
$carry[$key] = $value;
return $carry;
},
array()
);
And a solution in a single line:
array_column(array_map(function($item) { return explode('|', $item); }, $a), 1, 0)
Please note that it requires PHP 5.5 (this is the version when the function array_column() was introduced).
Not a one-liner, but...
<?php
$a = array(
'name|smith',
'kid|tom',
'wife|emily',
);
$a2 = array();
foreach($a AS $val) {
list($key, $value) = explode("|", $val);
$a2[$key] = $value;
}
print_r($a);
print_r($a2);
