I'm trying to create an array only from the basename of the url's of $member1 and $member2 and so on to $member(n).
the base array i'm using looks like this for a reason, since I'm using it for another foreach loop.
So the scheme looks like this:
$member1 = 'http://www.bla-bla.com/aFolder/anotherFolder';
$member2 = 'http://www.yada-yada.com/yetAnotherFolder/innerFolder';
$member3 = 'http://www.boo-boo.com/abcs/folder';
//this is the main array
$teams = array(
array("url" => $member1, "selector" => "a"),
array("url" => $member2, "selector" => "input"),
array("url" => $member3, "selector" => "h1"),...,...);
I would like to build a foreach that would create at the end an array with the values with basename($member(n)).
I would like my result to look like this:
Array
(
[0] => anotherFolder
[1] => innerFolder
[2] => folder
)
Thus far I've tried different ways to extract that specific value with no avail, I couldn't find a way on how to extract that specific value.
I'll appreciate the help.
$basenames = [];
foreach ($teams as $team) {
$basenames[] = basename($team['url']);
}
function getBaseName($array){
$return=array();
foreach($array as $arr)
{
$exp=explode("/",$arr['url']);
$return[]=array_pop($exp);
}
return $return;
}
$basenames[]=getBaseName($teams);
If I understood you right, try this:
$resArray = array();
foreach($teams as $team){
$resArray[] = basename($team['url']);
}
The solution using array_map and basename functions:
...
$result = array_map(function($v){ return basename($v['url']); }, $teams);
$array = array();
foreach($teams as $team){
$array[] = basename($team["url"]);
}
print_r($array);
will print
Array
(
[0] => anotherFolder
[1] => innerFolder
[2] => folder
)

This question already has answers here:
PHP rename array keys in multidimensional array
(10 answers)
Closed last month.
When I var_dump on a variable called $tags (a multidimensional array) I get this:
Array
(
[0] => Array
(
[name] => tabbing
[url] => tabbing
)
[1] => Array
(
[name] => tabby ridiman
[url] => tabby-ridiman
)
[2] => Array
(
[name] => tables
[url] => tables
)
[3] => Array
(
[name] => tabloids
[url] => tabloids
)
[4] => Array
(
[name] => taco bell
[url] => taco-bell
)
[5] => Array
(
[name] => tacos
[url] => tacos
)
)
I would like to rename all array keys called "url" to be called "value". What would be a good way to do this?
You could use array_map() to do it.
$tags = array_map(function($tag) {
return array(
'name' => $tag['name'],
'value' => $tag['url']
);
}, $tags);
Loop through, set new key, unset old key.
foreach($tags as &$val){
$val['value'] = $val['url'];
unset($val['url']);
}
Talking about functional PHP, I have this more generic answer:
array_map(function($arr){
$ret = $arr;
$ret['value'] = $ret['url'];
unset($ret['url']);
return $ret;
}, $tag);
}
Recursive php rename keys function:
function replaceKeys($oldKey, $newKey, array $input){
$return = array();
foreach ($input as $key => $value) {
if ($key===$oldKey)
$key = $newKey;
if (is_array($value))
$value = replaceKeys( $oldKey, $newKey, $value);
$return[$key] = $value;
}
return $return;
}
foreach ($basearr as &$row)
{
$row['value'] = $row['url'];
unset( $row['url'] );
}
unset($row);
This should work in most versions of PHP 4+. Array map using anonymous functions is not supported below 5.3.
Also the foreach examples will throw a warning when using strict PHP error handling.
Here is a small multi-dimensional key renaming function. It can also be used to process arrays to have the correct keys for integrity throughout your app. It will not throw any errors when a key does not exist.
function multi_rename_key(&$array, $old_keys, $new_keys)
{
if(!is_array($array)){
($array=="") ? $array=array() : false;
return $array;
}
foreach($array as &$arr){
if (is_array($old_keys))
{
foreach($new_keys as $k => $new_key)
{
(isset($old_keys[$k])) ? true : $old_keys[$k]=NULL;
$arr[$new_key] = (isset($arr[$old_keys[$k]]) ? $arr[$old_keys[$k]] : null);
unset($arr[$old_keys[$k]]);
}
}else{
$arr[$new_keys] = (isset($arr[$old_keys]) ? $arr[$old_keys] : null);
unset($arr[$old_keys]);
}
}
return $array;
}
Usage is simple. You can either change a single key like in your example:
multi_rename_key($tags, "url", "value");
or a more complex multikey
multi_rename_key($tags, array("url","name"), array("value","title"));
It uses similar syntax as preg_replace() where the amount of $old_keys and $new_keys should be the same. However when they are not a blank key is added. This means you can use it to add a sort if schema to your array.
Use this all the time, hope it helps!
Very simple approach to replace keys in a multidimensional array, and maybe even a bit dangerous, but should work fine if you have some kind of control over the source array:
$array = [ 'oldkey' => [ 'oldkey' => 'wow'] ];
$new_array = json_decode(str_replace('"oldkey":', '"newkey":', json_encode($array)));
print_r($new_array); // [ 'newkey' => [ 'newkey' => 'wow'] ]
This doesn't have to be difficult in the least. You can simply assign the arrays around regardless of how deep they are in a multi-dimensional array:
$array['key_old'] = $array['key_new'];
unset($array['key_old']);
You can do it without any loop
Like below
$tags = str_replace("url", "value", json_encode($tags));
$tags = json_decode($tags, true);
class DataHelper{
private static function __renameArrayKeysRecursive($map = [], &$array = [], $level = 0, &$storage = []) {
foreach ($map as $old => $new) {
$old = preg_replace('/([\.]{1}+)$/', '', trim($old));
if ($new) {
if (!is_array($new)) {
$array[$new] = $array[$old];
$storage[$level][$old] = $new;
unset($array[$old]);
} else {
if (isset($array[$old])) {
static::__renameArrayKeysRecursive($new, $array[$old], $level + 1, $storage);
} else if (isset($array[$storage[$level][$old]])) {
static::__renameArrayKeysRecursive($new, $array[$storage[$level][$old]], $level + 1, $storage);
}
}
}
}
}
/**
* Renames array keys. (add "." at the end of key in mapping array if you want rename multidimentional array key).
* #param type $map
* #param type $array
*/
public static function renameArrayKeys($map = [], &$array = [])
{
$storage = [];
static::__renameArrayKeysRecursive($map, $array, 0, $storage);
unset($storage);
}
}
Use:
DataHelper::renameArrayKeys([
'a' => 'b',
'abc.' => [
'abcd' => 'dcba'
]
], $yourArray);
It is from duplicated question
$json = '[
{"product_id":"63","product_batch":"BAtch1","product_quantity":"50","product_price":"200","discount":"0","net_price":"20000"},
{"product_id":"67","product_batch":"Batch2","product_quantity":"50","product_price":"200","discount":"0","net_price":"20000"}
]';
$array = json_decode($json, true);
$out = array_map(function ($product) {
return array_merge([
'price' => $product['product_price'],
'quantity' => $product['product_quantity'],
], array_flip(array_filter(array_flip($product), function ($value) {
return $value != 'product_price' && $value != 'product_quantity';
})));
}, $array);
var_dump($out);

This is how I rename keys, especially with data that has been uploaded in a spreadsheet:
function changeKeys($array, $new_keys) {
$newArray = [];
foreach($array as $row) {
$oldKeys = array_keys($row);
$indexedRow = [];
foreach($new_keys as $index => $newKey)
$indexedRow[$newKey] = isset($oldKeys[$index]) ? $row[$oldKeys[$index]] : '';
$newArray[] = $indexedRow;
}
return $newArray;
}
Based on the great solution provided by Alex, I created a little more flexible solution based on a scenario I was dealing with. So now you can use the same function for multiple arrays with different numbers of nested key pairs, you just need to pass in an array of key names to use as replacements.
$data_arr = [
0 => ['46894', 'SS'],
1 => ['46855', 'AZ'],
];
function renameKeys(&$data_arr, $columnNames) {
// change key names to be easier to work with.
$data_arr = array_map(function($tag) use( $columnNames) {
$tempArray = [];
$foreachindex = 0;
foreach ($tag as $key => $item) {
$tempArray[$columnNames[$foreachindex]] = $item;
$foreachindex++;
}
return $tempArray;
}, $data_arr);
}
renameKeys($data_arr, ["STRATEGY_ID","DATA_SOURCE"]);
this work perfectly for me
$some_options = array();;
if( !empty( $some_options ) ) {
foreach( $some_options as $theme_options_key => $theme_options_value ) {
if (strpos( $theme_options_key,'abc') !== false) { //first we check if the value contain
$theme_options_new_key = str_replace( 'abc', 'xyz', $theme_options_key ); //if yes, we simply replace
unset( $some_options[$theme_options_key] );
$some_options[$theme_options_new_key] = $theme_options_value;
}
}
}
return $some_options;
I have array multidimensional code like this:
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$eaten = 'grape';
unset($array[$eaten]);
and what i need is to delete 'grape' from the array because 'grape' already eaten. how to fix my code to unset the 'grape'?
and my question number two, if it can be unset, is there a way to unset multi value like
unset($array,['grape','orange']);
thanks for help..
You can remove eaten element by following way. Use array_search() you can find key at the position of your eaten element.
Here below code shows that in any multidimensional array you can call given function.
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$eaten = 'grape';
$array = removeElement($array, $eaten);
function removeElement($data_arr, $eaten)
{
foreach($data_arr as $k => $single)
{
if (count($single) != count($single, COUNT_RECURSIVE))
{
$data_arr[$k] = removeElement($single, $eaten);
}
else
{
if(($key = array_search($eaten, $single)) !== false)
{
unset($data_arr[$k][$key]);
}
}
}
return $data_arr;
}
P.S. Please note that you can unset() multiple elements in single call. But the way you are using unset is wrong.
Instead of using unset() i suggest you to create a new Array after removal of required value benefit is that, your original array will remain same, you can use it further:
Example:
// your array
$yourArr = array(
'fruits'=>array('apple','orange','grape', 'pineaple'),
'vegetables'=>array('tomato', 'potato')
);
// remove array that you need
$removeArr = array('grape','tomato');
$newArr = array();
foreach ($yourArr as $key => $value) {
foreach ($value as $finalVal) {
if(!in_array($finalVal, $removeArr)){ // check if available in removal array
$newArr[$key][] = $finalVal;
}
}
}
echo "<pre>";
print_r($newArr);
Result:
Array
(
[fruits] => Array
(
[0] => apple
[1] => orange
[2] => pineaple
)
[vegetables] => Array
(
[0] => potato
)
)
Explanation:
Using this array array('grape','tomato'); which will remove the value that you define in this array.
This is how I would do it.
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$unset_item = 'grape';
$array = array_map(function($items) use ($unset_item) {
$found = array_search($unset_item, $items);
if($found){
unset($items[$found]);
}
return $items;
}, $array);
I would like to build a multidimensional array from an array. For example I would like
$test = array (
0 => 'Tree',
1 => 'Trunk',
2 => 'Branch',
3 => 'Limb',
4 => 'Apple',
5 => 'Seed'
);
to become
$test =
array (
'Tree' => array (
'Trunk' => array (
'Branch' => array (
'Limb' => array (
'Apple' => array (
'Seed' => array ()
)
)
)
)
)
);
or more simply
$result[Tree][Trunk][Branch][Limb][Apple][Seed] = null;
I'm trying to do this with a recursive function but i'm hitting memory limit so I'm clearly doing it wrong.
<?php
$test = array (
0 => 'Tree',
1 => 'Trunk',
2 => 'Branch',
3 => 'Limb',
4 => 'Apple',
5 => 'Seed'
);
print_r($test);
print "results of function";
print_r(buildArray($test));
function buildArray (&$array, &$build = null)
{
if (count($array) > 0)
{
//create an array, pass the array to itself removing the first value
$temp = array_values($array);
unset ($temp[0]);
$build[$array[0]] = $temp;
buildArray($build,$temp);
return $build;
}
return $build;
}
Here's an approach with foreach and without recursion, which works:
function buildArray($array)
{
$new = array();
$current = &$new;
foreach($array as $key => $value)
{
$current[$value] = array();
$current = &$current[$value];
}
return $new;
}
[ Demo ]
Now your function... first, using $build[$array[0]] without defining it as an array first produces an E_NOTICE.
Second, your function is going into infinite recursion because you are not actually modifying $array ($temp isn't the same), so count($array) > 0 will be true for all of eternity.
And even if you were modifying $array, you couldn't use $array[0] anymore, because you unset that, and the indices don't just slide up. You would need array_shift for that.
After that, you pass $build and $temp to your function, which results in further because you now you assign $build to $temp, therefore creating another loop in your already-infinitely-recurring loop.
I was trying to fix all of the above in your code, but eventually realized that my code was now pretty much exactly the one from Pevara's answer, just with different variable names, so... that's that.
This function works recursively and does the trick:
function buildArray($from, $to = []) {
if (empty($from)) { return null; }
$to[array_shift($from)] = buildArray($from, $to);
return $to;
}
In your code I would expect you see an error. You are talking to $build in your first iteration as if it where an array, while you have defaulted it to null.
It seems to be easy
$res = array();
$i = count($test);
while ($i)
$res = array($test[--$i] => $res);
var_export($res);
return
array ( 'Tree' => array ( 'Trunk' => array ( 'Branch' => array ( 'Limb' => array ( 'Apple' => array ( 'Seed' => array ( ), ), ), ), ), ), )
Using a pointer, keep re-pointing it deeper. Your two output examples gave array() and null for the deepest value; this gives array() but if you want null, replace $p[$value] = array(); with $p[$value] = $test ? array() : null;
$test = array(
'Tree',
'Trunk',
'Branch',
'Limb',
'Apple',
'Seed'
);
$output = array();
$p = &$output;
while ($test) {
$value = array_shift($test);
$p[$value] = array();
$p = &$p[$value];
}
print_r($output);
This is the code I have:
$orders = Array();
foreach ($unassigned as $uorder) {
$array = Array(
"ordid" => $uorder->idord,
"fecha" => $uorder->datorod,
"cliente" => $uorder->idcli
);
array_push($orders[$uorder->user_id], $array);
}
print_r($orders);
Which results:
Array (
[vendor1] =>
[vendor2] =>
)
I want to make some kind of sort
So I could use $orders[vendor1][0][ordid] to find the first order that the vendor made.
You have to assign $orders[$uorder->user_id] as an array first, otherwise it doesn't make sense to push an item onto it. Additionally, you can use the shorthand append notation:
if(!isset($orders[$uorder->user_id]))
$orders[$uorder->user_id] = array();
$orders[$uorder->user_id][] = $array;
In your foreach loop check if $orders[$uorder->user_id] is an array, if not create one.
foreach($unassigned as $uorder):
if(! is_array($orders[$uorder->user_id]))
$orders[$uorder->user_id] = array();
array_push($orders[$uorder->user_id],Array("ordid" => $uorder->idord, "fecha" => $uorder->datorod, "cliente" => $uorder->idcli));
endforeach;
I'm sure this has been asked before, but I can't seem to find the answer.
To that end, I have an array that looks like this:
Array
(
[0] => Array
(
[status] => active
[sid] => 1
)
[1] => Array
(
[status] => expired
[sid] => 2
)
)
What I'd like to be able to do is type $arrayName["active"] and it return the SID code. I will be using this like a dictionary object of sorts. It's like I need to reindex the array so that it is the key/value pair that I need. I was just wondering if there was an easier way to do it.
You should convert your nested arrays into a single associative array. Something like this should take your example and turn it into an associative array:
$assoc_array = array();
foreach( $example_array as $values ) {
$assoc_array[$values["status"]] = $values["sid"];
}
You can then access the sid for a given status by using $assoc_array["expired"] (returns 2)
After seeing the others' solutions, I realize this might be bit of an overkill, but I'm still just gonna throw it out there:
$foo = array(
array('status' => 'active', 'sid' => 1),
array('status' => 'expired', 'sid' => 2),
);
// Get all the 'status' elements of each subarray
$keys = array_map(function($element) {
return $element['status'];
}, $foo);
// Get all the 'sid' elements of each subarray
$values = array_map(function($element) {
return $element['sid'];
}, $foo);
// Combine them into a single array, with keys from one and values from another
$bar = array_combine($keys, $values);
print_r($bar);
Which prints:
Array
(
[active] => 1
[expired] => 2
)
Manual pages:
array_map()
array_keys()
array_values()
array_combine()
Anonymous functions
You can use this function:
function findActive($my_array){
foreach($my_array as $array){
foreach($array as $val){
if($val['status']==='active'){
return $val['sid'];
}
}
}
return false;
}
access it via a loop or directly.
if($arrayName[0]['status'] == "active") {
echo $arrayName[0]['sid'];
}
If you want to check all the SIDs
foreach($arrayName as $item) {
if($item['status'] == "active") {
echo $item['sid'];
}
}
A more direct approach is just putting the loop in a function and return an array of all active session IDs
$sidArr = array();
foreach($yourArr as $val) {
if("active" == $val["status"]) {
array_push($sidArr, $val["sid"]);
}
}
reindex would be the best
$arrayName = array()
foreach ($data_array as $data)
$arrayName[$data['status']]=$data['sid'];
Or use a function
function get_sid($status)
{
global $data_array;
foreach ($data_array as $data) {
if ($data['status']==$status)
return $data['sid'];
}
return false;
}
