Description
Php Generate Key Value Array Php
$keys
, mixed$value
) : array Fills an array with the value of the value
parameter, using the values of the keys
array as keys.
Parameters
- Picks one or more random entries out of an array, and returns the key (or keys) of the random entries. It uses a pseudo random number generator that is not suitable for cryptographic purposes.
- How can I add key value pairs to an array? This won't work. The only thing with this solution is that this way you can only add key-value pairs to the end of the array, even if you have integer keys. PHP arrays are ordered. You can create the single value array key-value as.
- Nov 21, 2019 php search multidimensional array by key and value. Here we will learn how to search in the multidimensional array for value and return key. Also learn how to search multidimensional array for key and return value. Sometimes we need to search in an array or multidimensional array by key or value without using any function.
- Jul 16, 2011 Hi Lotte, you make an array filled with the numbers 1.12 and swap randomly pairs. I have chosen for generating the pairs to take the index i, but you could also generate 2 random numbers and swap those.
- Create Key Value Pair Array Using Javascript, Our today's article is simple but demanding. Most of the new or experience java-script developer required below code. In this code snippet I have define java-script array values are in the form of key and value.
Arrayfill cannot be used to setup only missing keys in an array. This may be necessary for example before using implode on a sparse filled array. The solution is to use this function. PHP Array Push Example. PHP arraypush function is used to insert new items at the end of an array and get the updated number of array elements. You may add as many values as you need. Your added elements will always have numeric keys, even if the array itself has string keys. PHP array push function has been introduced in PHP 4.
keys
Array of values that will be used as keys. Illegal values for key will be converted to string.
value
Value to use for filling
Examples
Example #1 array_fill_keys() example
<?php
$keys = array('foo', 5, 10, 'bar');
$a = array_fill_keys($keys, 'banana');
print_r($a);
?>

- array_fill() - Fill an array with values
- array_combine() - Creates an array by using one array for keys and another for its values
<?php
$a = array('1');
var_dump(array_fill_keys($a, 'test'));
?>
array(1) {
[1]=>
string(4) 'test'
}
now string key '1' become an integer value 1, be careful.
If an associative array is used as the second parameter of array_fill_keys, then the associative array will be appended in all the values of the first array.
e.g.
<?php
$array1 = array(
'a' => 'first',
'b' => 'second',
'c' => 'something',
'red'
);
$array2 = array(
'a' => 'first',
'b' => 'something',
'letsc'
);
print_r(array_fill_keys($array1, $array2));
?>
The output will be
Array(
[first] => Array(
[a] => first,
[b] => something,
[0] => letsc
),
[second] => Array(
[a] => first,
[b] => something,
[0] => letsc
),
[something] => Array(
[a] => first,
[b] => something,
[0] => letsc
),
[red] => Array(
[a] => first,
[b] => something,
[0] => letsc
)
)
This function does the same as:
<?php
$array = array_combine($keys,array_fill(0,count($keys),$value));
?>
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, $arr2);
returns:
abc => 452, def =>128
Scratchy's version still doesn't work like the definition describes. Here's one that can take a mixed variable as the second parameter, defaulting to an empty string if it's not specified. Don't know if this is exactly how the function works in later versions but it's at least a lot closer.
function array_fill_keys($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] =>
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 $arraydisplay;
}
To remove arbitrary keys from an associative array:
<?php
function nuke_keys($keys, $array) {
return array_diff_key($array, array_fill_keys($keys, 0));
}
$array = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$keys = array('red', 'purple');
print_r(nuke_keys($keys, $array));
?>
The above snippet will return:
Array
(
[blue] => 1
[green] => 3
)

// Fill it with value.
$keys = array_fill_keys($keys, 'banana');
print_r($keys);
// Fill it different value.
$apples = array_fill_keys(array_keys($keys), 'apple');
print_r($apples);
// Output:
Array (
[1] => banana
[2] => banana

)
Array (
[1] => apple
[2] => apple
[3] => apple
)

Hey everyone i'm currently learning more about javascript and wanted to know how to do something like this in PHP which is a multidimensional array with key pairs
But how would i do something like this in javascript this is what i have attempted and so far only got errors i'm using an object rather than array if i'm going about this wrong please tell me haha
Why do you try to make an Object? In Object JS doing it other way(with ':' and ',')
Php Get Array Key
Butif you need a multidimensional array do this way:
Would i just access the variables in the array like
Php Key In Array
Hi Tunde,
Since an array is an object in javascript, would something like this suit you?
You can access each property either like this: multiarray.cat.name or if you prefer it to be like php: multiarray['cat']['legs']
Oh, I see! Word apple mac free download. What you calling array is collection indeed. To access it like hotels['hilton']['name'] you need such object:

Your awesome haha sorry i thought it was called the same in js but thats exactly what i'm looking for are there any methods to add new items into the collection ?

Php Create Key Value Array
Awesome that works thanks for all your help mate :D
These are commonly known as Object Literals in JavaScript but yes they are indeed associative arrays since the indexes are named (with a string) and not a numeric index.
