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;
}
