Convert array in array to string - php

I wonder if there's easy way to convert array which is in another array to string and keep it in that array ? The array which is inside array always consists of only 1 key. This is array that I have now:
array(6) {
["miestas"]=>
string(2) "CC"
["checkbox"]=>
array(1) {
[0]=>
string(1) "1"
}
["kiekis"]=>
string(5) "Three"
}
And this is the result what I want to get:
array(6) {
["miestas"]=>
string(2) "CC"
["checkbox"]=>
string(1) "1"
["kiekis"]=>
string(5) "Three"
}

Read this: http://php.net/array
Use this: $array['checkbox'] = $array['checkbox'][0];

You can type cast the value
$data['checkbox'] = (string) $data['checkbox'];

array_replace
$replacement = array('checkbox' => 1);
$outputYouWant = array_replace($yourArray, $replacement);
print_r($outputYouWant);

Loops through the input array and checks if value is an array using is_array function. Pushes value array's value at index zero if an array otherwise pushes value to the result array.
$input = array('miestas' => 'CC', 'checkbox' => array("1"), 'kiekis' => 'Three');
$result = array();
foreach($input as $key=>$value) {
$result[$key] = is_array($value) ? $value[0] : $value;
}
// var_dump($result);

Generate multidimensional array based on given array

I have an array say,
$arr = ["x", "y", "z"];
What I want to achieve is create another array based on given array such as
$arr1["x" =>["y" => ["z"]]] = "some value";
Any idea to achieve this? Thanks in advance.
Edited:
'some value' is just a dummy data. What I'm trying to achieve is the multidimensional structure.
You can recursively build an array, taking and removing the first element of an array on each call :
function buildArray($arr, $someValue)
{
if (count($arr) == 0)
return $someValue;
// the key is the first element of the array,
// removed and returned at the same time using array_shift()
return [ array_shift($arr) => buildArray($arr, $someValue) ];
}
$arr = ["x", "y", "z"];
$arr1 = buildArray($arr, "some value");
var_dump($arr1);
echo "------------------------" . PHP_EOL;
// note that $arr is preserved
var_dump($arr);
This outputs :
array(1) {
["x"]=>
array(1) {
["y"]=>
array(1) {
["z"]=>
string(10) "some value"
}
}
}
------------------------
array(3) {
[0]=>
string(1) "x"
[1]=>
string(1) "y"
[2]=>
string(1) "z"
}
$keys = array('key1', 'key2', 'key3');
$value = 'some value';
$md = array();
$md[$keys[count($keys)-1]] = $value;
for($i=count($keys)-2; $i>-1; $i--)
{
$md[$keys[$i]] = $md;
unset($md[$keys[$i+1]]);
}
print_r($md);
You need to create recursive function:
function rec_arr($ar, $val){
$res = [];
if(is_array($ar) && count($ar)>0){
$tmp = $ar[0]; // catching the first value
unset($ar[0]); // unset first value from given array
sort($ar); // makes indexes as 0,1,...
$res[$tmp] = rec_arr($ar, $val); // recursion
} else {
return $val; // passing value to the last element
}
return $res;
}
Demo
Outputs:
Array
(
[x] => Array
(
[y] => Array
(
[z] => some value
)
)
)

Php array get all values that are repeating

I have a Php array that have values of times as array values and timestamps as key array is like this:
array(
144454884=>"12:00am", 145454884=>"12:30am", 144474884=>"1:00am", 144454864=>"1:30am", 143354884=>"1:00am", 144654884=>"1:30am", 1444567584=>"2:00am "
);
Timestamp values in above example are not real I wrote an example they are useless anyway unless your timezone matches mine.
Problem:
I need to get "1:00am" and "1:30am" twice I can get repeating values 1 time as shown in answer here:
php return only duplicated entries from an array
I need both repeating values two times with both keys and values being repeated because I need to eliminate those timestamps from week time on my system because of daylight saving a time is repeating and I don't want to show 1:00am at all I just want to show this time as unavailable.
I am not 100% sure what you wanted but this is what I think you need.
Assuming your input array is called $a
$b = array_flip(array_flip($a));
$c = array_diff_key($a, $b);
$b will contain an array of unique values.
$c will contain the elements that were removed.
Results of $b and $c are as follows:
array(5) {
[144454884] = string(7) "12:00am"
[145454884] = string(7) "12:30am"
[143354884] = string(6) "1:00am"
[144654884] = string(6) "1:30am"
[1444567584] = string(7) "2:00am "
}
array(2) {
[144474884] = string(6) "1:00am"
[144454864] = string(6) "1:30am"
}
This code works :
<?php
$array_new = [];
$array_tmp = [];
$array = array(1=>'1233',2=>'12334',3 =>'Hello' ,4=>'hello', 5=>'U');
//loop trough all elements in array and for ever element create key
//For "world" key is "world"
//For "World" key is "world"
//For "WORLD" key is "world"
//So all this cases have same key and differenet representation eg. "world" => ["world","World","WORLD"]
foreach($array as $k => $v){
$index = strtolower($v);
$array_tmp[$index][] = $v;
}
//loop trough new array with new keys and if there are more than one element(> 1) for some key, all of his representations put in new array
foreach($array_tmp as $k => $v){
if(count($v) > 1){
foreach($v as $k2 => $v2){
$array_new[] = $v2;
}
}
}
echo '<pre>';
print_r($array_new);
echo '<pre>';
A possible solution keeping the key information (I will assign the intermediate results to their own variables otherwise it can be confusing to read)
$array = array(
143354883 => "1:00am",
144454884 => "12:00am",
145454884 => "12:30am",
144474884 => "1:00am",
144454864 => "1:30am",
143354884 => "1:00am",
144654884 => "1:30am",
1444567584 => "2:00am ",
0 => 4,
1 => 4,
2 => 4,
3 => "Test",
4 => "TEST",
5 => "test "
);
// Used this array_iunique function: http://stackoverflow.com/questions/2276349/case-insensitive-array-unique
function array_iunique($array) {
return array_intersect_key(
$array,
array_unique(array_map("StrToLower",$array))
);
}
$unique = array_iunique($array);
// Then get the difference by key, that will give you all the duplicate values:
$diff_key = array_diff_key($array, $unique);
// Now we have to find the values that are in the $diff_key and the $unique because we also want to have those:
$correspondingValues = array_uintersect($unique, $diff_key, "strcasecmp");
// Then we have to combine the $duplicate values with the $diff_key and preserve the keys:
$result = array_replace($correspondingValues, $diff_key);
var_dump($result);
Will result in:
array(10) {
[143354883]=>
string(6) "1:00am"
[144454864]=>
string(6) "1:30am"
[0]=>
int(4)
[3]=>
string(4) "Test"
[144474884]=>
string(6) "1:00am"
[143354884]=>
string(6) "1:00am"
[144654884]=>
string(6) "1:30am"
[1]=>
int(4)
[2]=>
int(4)
[4]=>
string(4) "TEST"
}

Change indexed Array to Associative Array PHP

I have an array from json_decode. And i want to reformat it.
this is my array format.
["Schedule"]=>array(1) {
["Origin"]=>
string(3) "LAX"
["Destination"]=>
string(2) "CGK"
["DateMarket"]=>
array(2) {
["DepartDate"]=>
string(19) "2015-02-01T00:00:00"
["Journeys"]=>
array(6) {
[0]=>
array(6) {
[0]=>
string(2) "3210"
[1]=>
string(14) "Plane Name"
[2]=>
string(8) "20150201"
[3]=>
string(8) "20150201"
[4]=>
string(4) "0815"
[5]=>
string(4) "1524"
}
}
}
And i want change the indexed array to associative with foreach function.
And here is my PHP code
foreach ($response->Schedule['DateMarket']['Journeys'] as $key=>$value) {
$value->Name= $value[1];
}
But i got an error "Attempt to assign property of non-object on line xXx..
My Question is, how to insert a new associative array to indexed array like the example that i've provide.
UPDATE : I've tried this solution
foreach ($response->Schedule['DateMarket']['Journeys'] as $key=>$value) {
$value['Name']=$value[1];
}
But my array format still the same, no error.
In this line:
$value->Name= $value[1];
You expect $value to be both object ($value->Name) and array ($value[1]).
Change it to something like:
foreach ($response->Schedule['DateMarket']['Journeys'] as $key=>$value) {
$response->Schedule['DateMarket']['Journeys'][$key]['Name'] = $value[1];
}
Or even better, without foreach:
$keys = array(
0 => 'Id',
1 => 'Name',
2 => 'DateStart',
3 => 'DateEnd',
4 => 'HourStart',
5 => 'HourEnd',
);
$values = $response->Schedule['DateMarket']['Journeys'];
$response->Schedule['DateMarket']['Journeys'] = array_combine( $keys , $values );
Array_combine makes an array using keys from one input and alues from the other.
Docs: http://php.net/manual/en/function.array-combine.php
Try this:
foreach ($response->Schedule['DateMarket']['Journeys'] as $key=>$value) {
$value['Name'] = $value[1];
}
You want to create new array index, but try to create new object.
foreach ($response->Schedule['DateMarket']['Journeys'] as $key => $value) {
$value['Name'] = $value[1];
}

PHP - How to move the empty values of an array to its last positions

How can I move the empty values of an array to its last position?
For example:
$givenArray = array(
0=>'green',
1=>'',
2=>'red',
3=>'',
4=>'blue'
);
$requiredArray = array(
0=>'green',
1=>'red',
2=>'blue',
3=>'',
4=>''
);
Provided that the non empty values should not be sorted. It should be as it is, i.e. only the empty values should move to the end of an array.
I need exactly what my examples show.
You are looking for all values not being an empty string ("") first and then all values being an empty string:
$requiredArray = array_diff($givenArray, array(''))
+ array_intersect($givenArray, array(''));
This will give you:
array(5) {
[0]=> string(5) "green"
[2]=> string(3) "red"
[4]=> string(4) "blue"
[1]=> string(0) ""
[3]=> string(0) ""
}
Which has the benefit that it preserves key => value association. If you need to renumber the keys, just apply the array_values function:
$requiredArray = array_values($requiredArray);
This will turn it into your required layout (Demo):
array(5) {
[0]=> string(5) "green"
[1]=> string(3) "red"
[2]=> string(4) "blue"
[3]=> string(0) ""
[4]=> string(0) ""
}
There are much better/more elegant answers in this thread already, but this works too:
//strip empties and move to end
foreach ($givenArray as $key => $value)
{
if ($value === "")
{
unset($givenArray[$key]);
$givenArray[] = $value;
}
}
// rebuild array index
$givenArray = array_values($givenArray);
Codepad demo
Try using usort.
function empty_sort ($a, $b) {
if ($a == '' && $b != '') return 1;
if ($b == '' && $a != '') return -1;
return 0;
}
usort($array, 'empty_sort');
Which gives (Demo):
Array
(
[0] => blue
[1] => green
[2] => red
[3] =>
[4] =>
)
This should work:
function sortempty( $a, $b ) {
return empty( $a );
}
usort( $array, 'sortempty' );
Output (Demo):
Array
(
[0] => blue
[1] => green
[2] => red
[3] =>
[4] =>
)
usort() allows you to sort an array using a user-defined function. I return if $a is empty or not. If it's empty, return 1 which makes value $a shift right (or down) in the array.
$givenArray = array(
0=>'green',
1=>'',
2=>'red',
3=>'',
4=>'blue'
);
foreach($givenArray as $value){
if(empty($value)){
$newarray[] = $value;
}else{
$filledarray[] = $value;
}
}
$requiredArray = array_merge($filledarray,$newarray);
There is usort($array, $callback) function that will sort with your own custom callback.

target numeric keys only in array

I have an array with 2 kinds of keys, strings and integers. I want to do foreach() on this array and want to do it for numeric keys only. What is the most elegant way of doing it?
Here's a complicated method using array_filter() to return the numeric keys then iterate over them.
// $input_array is your original array with numeric and string keys
// array_filter() returns an array of the numeric keys
// Use an anonymous function if logic beyond a simple built-in filtering function is needed
$numerickeys = array_filter(array_keys($input_array), function($k) {return is_int($k);});
// But in this simple case where the filter function is a plain
// built-in function requiring one argument, it can be passed as a string:
// Really, this is all that's needed:
$numerickeys = array_filter(array_keys($input_array), 'is_int');
foreach ($numerickeys as $key) {
// do something with $input_array[$key']
}
It's much easier though to just foreach over everything:
foreach ($input_array as $key => $val) {
if (is_int($key)) {
// do stuff
}
}
Edit Misread original post and thought I saw "numeric" rather than "integer" keys. Updated to use is_int() rather than is_numeric().
foreach($array as $key => $val) {
if(!is_int($key))
continue;
// rest of the logic
}
This one-liner returns a new array with the values and its numeric keys:
$new_array = array_filter($my_array, 'is_int', ARRAY_FILTER_USE_KEY);
so if we have this:
array(
'fruit' => 'banana'
1 => 'papaya'
)
..we get this:
array(
1 => 'papaya'
)
Using array_filter you must aware if you have value that similar as FALSE.
This is my solution:
function filterArrayKeyInteger(Array $array) {
$integer = array_filter($array, function ($key) {
if ($key === 0 || is_int($key)) {
return true;
}
}, ARRAY_FILTER_USE_KEY);
return array_intersect_key($array, $integer);
}
$a = [0, false, 'aa','bb', 'cc', 'dd' => 'dd', '9.9' => 9.9];
$b = filterArrayKeyInteger($a);
Result of vardump
var_dump(a): array(7) {
[0]=>
int(0)
[1]=>
bool(false)
[2]=>
string(2) "aa"
[3]=>
string(2) "bb"
[4]=>
string(2) "cc"
["dd"]=>
string(2) "dd"
["9.9"]=>
float(9.9)
}
var_dump(b): array(5) {
[0]=>
int(0)
[1]=>
bool(false)
[2]=>
string(2) "aa"
[3]=>
string(2) "bb"
[4]=>
string(2) "cc"
}
