Got a rather quick one for you guys if you got time.

I am looking for a 1 liner PHP solution to do this. (not sure if it is possible through the array functions)

Basically I want to remap an array based on the one item present in each.

Example

array(
[0] => array(
[id] => 1234,
[name] => blah
[properties] => whatever
),
[1] => array(
[id] => 5678,
[name] => blah2
[properties] => foobar
)
);

I want to take this array and map it to

array( [1234] => array(
[name] => blah,
[properties] => whatever
),
[5678] => array(
[name] => blah2
[properties] => foobar
));

Basically remapping the array to one of the items present in each element. I am currently using a tempArray and looping through and this works fine but I was curious if there was a 1 line way using the array functions (possibly combining a few) to make a one line php call to do the same thing.

PHP: array_walk - Manual

Should be able to create a custom function that takes the first element of the subarray and makes it the key of the parent.

That does not seem like a one line solution.

PHP Code:

<?php

$a=array(array('id'=>1234,'name'=>'blah','properties'=>'whatever'),

        array('id'=>5678,'name'=>'blah2','properties'=>'foobar'));

$b=array();

var_dump($a);

array_walk($a,'c');function c($v,$k){global $b;$b[$v['id']]=$v;unset($b[$v['id']]['id']);}

var_dump($b);

?>

array(2) {
[0]=>
array(3) {
["id"]=>
int(1234)
["name"]=>
string(4) "blah"
["properties"]=>
string(8) "whatever"
}
[1]=>
array(3) {
["id"]=>
int(5678)
["name"]=>
string(5) "blah2"
["properties"]=>
string(6) "foobar"
}
}
array(2) {
[1234]=>
array(2) {
["name"]=>
string(4) "blah"
["properties"]=>
string(8) "whatever"
}
[5678]=>
array(2) {
["name"]=>
string(5) "blah2"
["properties"]=>
string(6) "foobar"
}
}

I stand corrected.
LOL!

Thanks wire. I actually am going to use that, because it's a little more obfuscated and if anyone else ever has to look at my code I can imagine a good wtf coming their mouth. I do enjoy those WTFs for sometimes causing your fellow programmers a little pain during the day relieves a little stress.

Mark this as solved.
