ok, assuming I have 5 arrays, all just indexed arrays, and I would like to combine them, this is the best way I can figure, is there a better way to handle this?
function mymap_arrays(){
$args=func_get_args();
$key=array_shift($args);
return array_combine($key,$args);
}
$keys=array('u1','u2','u3');
$names=array('Bob','Fred','Joe');
$emails=array('[email protected]','[email protected]','[email protected]');
$ids=array(1,2,3);
$u_keys=array_fill(0,count($names),array('name','email','id'));
$users=array_combine($keys,array_map('mymap_arrays',$u_keys,$names,$emails,$ids));
this returns:
Array
(
[u1] => Array
(
[name] => Bob
[email] => [email protected]
[id] => 1
)
[u2] => Array
(
[name] => Fred
[email] => [email protected]
[id] => 2
)
[u3] => Array
(
[name] => Joe
[email] => [email protected]
[id] => 3
)
)
EDIT: After lots of benchmarking I wend with a version of Glass Robots answer to handle a variable number of arrays, it's slower than his obviously, but faster than my original:
function test_my_new(){
$args=func_get_args();
$keys=array_shift($args);
$vkeys=array_shift($args);
$results=array();
foreach($args as $key=>$array){
$vkey=array_shift($vkeys);
foreach($array as $akey=>$val){
$result[$keys[$akey]][$vkey]=$val;
}
}
return $result;
}
$keys=array('u1','u2','u3');
$names=array('Bob','Fred','Joe');
$emails=array('[email protected]','[email protected]','[email protected]');
$ids=array(1,2,3);
$vkeys=array('name','email','id');
test_my_new($keys,$vkeys,$names,$emails,$ids);
