array_fill_keys — Befüllt ein Array mit Werten mit den übergebenen Schlüsseln
Befüllt ein Array mit dem Wert, der im Parameter value übergeben wurde, und verwendet dabei die Werte des Arrays keys als Schlüssel.
Ein Array mit den Werten, die als Schlüssel verwendet werden. Für Schlüssel ungültige Werte werden in einen String konvertiert.
Der Wert, der zum Befüllen des Arrays verwendet wird
Gibt das befüllte Array zurück
Beispiel #1 array_fill_keys()-Beispiel
<?php
$keys = array('foo', 5, 10, 'bar');
$a = array_fill_keys($keys, 'Banane');
print_r($a);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Array
(
[foo] => Banane
[5] => Banane
[10] => Banane
[bar] => Banane
)
This function does the same as:
<?php
$array = array_combine($keys,array_fill(0,count($keys),$value));
?>
Scratchy's version still doesn't work like the definition describes. Here's one that can take a mixed variable as the second parameter, defaulting to an empty string if it's not specified. Don't know if this is exactly how the function works in later versions but it's at least a lot closer.
function array_fill_keys($target, $value = '') {
if(is_array($target)) {
foreach($target as $key => $val) {
$filledArray[$val] = is_array($value) ? $value[$key] : $value;
}
}
return $filledArray;
}
This works for either strings or numerics, so if we have
$arr1 = array(0 => 'abc', 1 => 'def');
$arr2 = array(0 => 452, 1 => 128);
$arr3 = array(0 => 'foo', 1 => 'bar');
then
array_fill_keys($arr1,$arr2)
returns: [abc] => 452, [def] => 128
array_fill_keys($arr1,0)
returns: [abc] => 0, [def] => 0
array_fill_keys($arr2,$arr3)
returns: [452] => foo, [128] => bar
array_fill_keys($arr3,'BLAH')
returns: [foo] => BLAH, [bar] => BLAH
and array_fill_keys($arr1)
returns: [abc] =>, [def] =>
RE: bananasims at hotmail dot com
I also needed a work around to not having a new version of PHP and wanting my own keys. bananasims code doesn't like having an array as the second parameter...
Here's a slightly modified version than can handle 2 arrays as inputs:
//we want these values to be keys
$arr1 = (0 => "abc", 1 => "def");
/we want these values to be values
$arr2 = (0 => 452, 1 => 128);
function array_fill_keys($keyArray, $valueArray) {
if(is_array($keyArray)) {
foreach($keyArray as $key => $value) {
$filledArray[$value] = $valueArray[$key];
}
}
return $filledArray;
}
array_fill_keys($arr1, $arr2);
returns:
abc => 452, def =>128
Some of the versions do not have this function.
I try to write it myself.
You may refer to my script below
function array_fill_keys($array, $values) {
if(is_array($array)) {
foreach($array as $key => $value) {
$arraydisplay[$array[$key]] = $values;
}
}
return $arraydisplay;
}
