So I've got a list of paths, such as:
path/to/directory/file1
path/directory/file2
path2/dir/file3
path2/dir/file4
And I'd like to convert them into a multidimensional array like this:
array(
path => array(
to => array(
directory => array(
file1 => someValue
),
),
directory => array(
file2 => someValue
),
),
path2 => array(
dir => array(
file3 => someValue,
file4 => someValue
)
)
)
My first thought was to explode() the paths into segments and set up the array using a foreach loop, something like this:
$arr = array();
foreach ( $path as $p ) {
$segments = explode('/', $p);
$str = '';
foreach ( $segments as $s ) {
$str .= "[$s]";
}
$arr{$str} = $someValue;
}
But this doesn't work, and since the number of segments varies, I've kinda got stumped. Is there away to do this?
If somevalue can be an empty array:
<?php
$result = array();
$input = [
'path/to/directory/file1',
'path/directory/file2',
'path2/dir/file3',
'path2/dir/file4',
];
foreach( $input as $e ) {
nest( $result, explode('/', $e));
}
var_export($result);
function nest(array &$target, array $parts) {
if ( empty($parts) ) {
return;
}
else {
$e = array_shift($parts);
if ( !isset($target[$e]) ) {
$target[$e] = [];
}
nest($target[$e], $parts);
}
}
Here is the solution and a easy way
Just Reverse the whole exploded array and start creating array within a Array
$path[1] = "path/to/directory/file1";
$path[2] = "path/directory/file2";
$path[3] = "path2/dir/file3";
$path[4] = "path2/dir/file4";
$arr = array();
$b = array();
$k = 0;
foreach($path as $p) {
$c = 0;
$segments = explode('/', $p);
$reversed = array_reverse($segments);
foreach($reversed as $s) {
if ($c == 0) {
$g[$k] = array($s => "somevalue");
} else {
$g[$k] = array($s => $g[$k]);
}
$c++;
}
$k++;
}
var_dump($g);
Thanks so much VolkerK! Your answer didn't quite answer my question but it got me on the right track. Here's the version I ended up using to get it to work:
$result = array();
$input = [
'path/to/directory/file1' => 'someValue',
'path/directory/file2' => 'someValue',
'path2/dir/file3' => 'someValue',
'path2/dir/file4' => 'someValue',
];
foreach( $input as $e=>$val ) {
nest( $result, explode('/', $e), $val);
}
var_export($result);
function nest(array &$target, array $parts, $leafValue) {
$e = array_shift($parts);
if ( empty($parts) ) {
$target[$e] = $leafValue;
return;
}
if ( !isset($target[$e]) ) {
$target[$e] = [];
}
nest($target[$e], $parts, $leafValue);
}
I basically just added the somevalue as $leafValue and moved the base case around so that it would add the leafValue instead of a blank array at the end.
This results in:
Array
(
[path] => Array
(
[to] => Array
(
[directory] => Array
(
[file1] => someValue
)
)
[directory] => Array
(
[file2] => someValue
)
)
[path2] => Array
(
[dir] => Array
(
[file3] => someValue
[file4] => someValue
)
)
)
Thanks a lot!
It can be done without recursion
$path = array(
'path/to/directory/file1',
'path/directory/file2',
'path2/dir/file3',
'path2/dir/file4');
$arr = [];
$someValue = 'someValue';
foreach ( $path as $p ) {
$segments = explode('/', $p);
$str = '';
$p = &$arr;
foreach ( $segments as $s ) {
if (! isset($p[$s] ) ) $p[$s] = array();
$p = &$p[$s];
}
$p = $someValue;
}
print_r($arr);
I try to parse a list of url strings, after two hours of work I don't reach any result, the list of url strings look like this:
$url_list = array(
'http://google.com',
'http://localhost:8080/test/project/',
'http://mail.yahoo.com',
'http://www.bing.com',
'http://www.phpromania.net/forum/viewtopic.php?f=24&t=7549',
'https://prodgame10.alliances.commandandconquer.com/12/index.aspx',
'https://prodgame10.alliances.commandandconquer.ro/12/index.aspx',
);
Output should be:
Array
(
[0] => .google.com
[1] => .localhost
[2] => .yahoo.com
[3] => .bing.com
[4] => .phpromania.net
[5] => .commandandconquer.com
)
The first thing what induce me in the error zone is more than 2 dots in the url.
Any algorithm example?
This is what I try:
$url_list = array(
'http://google.com',
'http://localhost:8080/test/project/',
'http://mail.yahoo.com',
'http://www.bing.com',
'http://www.phpromania.net/forum/viewtopic.php?f=24&t=27549',
'https://prodgame10.alliances.commandandconquer.com/12/index.aspx',
);
function size($list)
{
$i=0;
while($list[++$i]!=NULL);
return $i;
}
function url_Host($list)
{
$listSize = size($list)-1;
do
{
$strSize = size($list[$listSize]);
$points = 0;
$dpoints = 0;
$tmpString = '';
do
{
$currentChar = $list[$listSize][$strSize];
if(ord('.')==ord($currentChar))
{
$tmpString .= '.';
$points++;
}
else if(ord(':')==ord($currentChar))
{
$tmpString .= ':';
$dpoints++;
}
}while($list[$listSize][--$strSize]!=NULL);
print $tmpString;
$strSize = size($list[$listSize]);
$tmpString = '';
do
{
$slice = false;
$currentChar = $list[$listSize][$strSize];
if($dpoints > 2)
{
if(ord('\\')==ord($curentChar)) $slice = true;
$tmpString .= '';
}
}while($list[$listSize][--$strSize]!=NULL);
print $tmpString."<br />";
}while($list[--$listSize]);
}
url_Host($url_list);
You can use the built-in function parse_url() as follows:
function getDomain($url)
{
$domain = implode('.', array_slice(explode('.', parse_url($url, PHP_URL_HOST)), -2));
return $domain;
}
Test cases:
foreach ($url_list as $url) {
$result[] = getDomain($url);
}
Output:
Array
(
[0] => google.com
[1] => localhost
[2] => yahoo.com
[3] => bing.com
[4] => phpromania.net
[5] => commandandconquer.com
[6] => commandandconquer.ro
)
As for the dots, you can manually prepend them to string, like so:
$result[] = "." . getDomain($url);
I'm not sure why you need to do this, but this should work.
Demo!
Look at parse_url. For example:
$url = 'http://www.phpromania.net/forum/viewtopic.php?f=24&t=7549';
$host = parse_url($url, PHP_URL_HOST);
First the result for localhost is no sense, but try this:
$result =array();
foreach($url_list as $u){
$arr = explode('//',$u);
$arr2 = explode('.', $arr[1]);
if($arr2[0] == 'www')
array_push($result, $arr2[1]);
else
array_push($result, $arr2[0]);
}
We can also use array_map() with an arrow function to simplify the code.
I'm refactoring #Alessandro Minoccheri's code here.
$domains = array_map(fn($url) => implode('.', array_slice(explode('.', parse_url($url, PHP_URL_HOST)), -2)),$urls);
var_dump($domains);
I need to extract a associative array keys into a string and implode with "/" or any character/symbols.
For eg:
$array = array([key1] =>
array([key11] =>
array([key111] => 'value111',
[key112] => 'value112',
[key113] => 'value113',
),
),
);
I need an output as below array:
array([0] => 'key1/key11/key111',[1] => 'key1/key11/key112', [2] => 'key1/key11/key112');
I've edited an answer given here and came up with the following code.
function listArrayRecursive($someArray, &$outputArray, $separator = "/") {
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($someArray), RecursiveIteratorIterator::SELF_FIRST);
foreach ($iterator as $k => $v) {
if (!$iterator->hasChildren()) {
for ($p = array(), $i = 0, $z = $iterator->getDepth(); $i <= $z; $i++) {
$p[] = $iterator->getSubIterator($i)->key();
}
$path = implode($separator, $p);
$outputArray[] = $path;
}
}
}
$outputArray = array();
listArrayRecursive($array, $outputArray);
print_r($outputArray);
Input:
Array
(
[key1] => Array
(
[key11] => Array
(
[key111] => value111
[key112] => value113
[key113] => value113
)
)
)
Output:
Array
(
[0] => key1/key11/key111
[1] => key1/key11/key112
[2] => key1/key11/key113
)
Works for different depth of array:
function getKeys($array, $prefix='', $separator = '/') {
$return = array();
foreach($array as $key => $value) {
if (!is_array($value)) $return[] = $prefix . $key;
else $return = array_merge($return, getKeys($value, $prefix . $key . separator), $separator);
}
return $return;
}
$keys = getKeys($array, '', '#');
See online fiddle http://ideone.com/krU4Xn
you could do something like...
$mapArray = array();
$symbol = '/';
foreach($array as $k =>$v)
foreach($v as $k1 =>$v1)
foreach($v1 as $k2 =>$v2)
$mapArray[] = $k.$symbol.$k1.$symbol.$k2;
also this obviously only works in this particular case, if it needs to be more generic it can be done, but I think this should get you started.
I want to dissect an array like this:
[
"ID",
"UUID",
"pushNotifications.sent",
"campaigns.boundDate",
"campaigns.endDate",
"campaigns.pushMessages.sentDate",
"pushNotifications.tapped"
]
To a format like this:
{
"ID" : 1,
"UUID" : 1,
"pushNotifications" :
{
"sent" : 1,
"tapped" : 1
},
"campaigns" :
{
"boundDate" : 1,
"endDate" : 1,
"pushMessages" :
{
"endDate" : 1
}
}
}
It would be great if I could just set a value on an associative array in a keypath-like manner:
//To achieve this:
$dissected['campaigns']['pushMessages']['sentDate'] = 1;
//By something like this:
$keypath = 'campaigns.pushMessages.sentDate';
$dissected{$keypath} = 1;
How to do this in PHP?
You can use :
$array = [
"ID",
"UUID",
"pushNotifications.sent",
"campaigns.boundDate",
"campaigns.endDate",
"campaigns.pushMessages.sentDate",
"pushNotifications.tapped"
];
// Build Data
$data = array();
foreach($array as $v) {
setValue($data, $v, 1);
}
// Get Value
echo getValue($data, "campaigns.pushMessages.sentDate"); // output 1
Function Used
function setValue(array &$data, $path, $value) {
$temp = &$data;
foreach(explode(".", $path) as $key) {
$temp = &$temp[$key];
}
$temp = $value;
}
function getValue($data, $path) {
$temp = $data;
foreach(explode(".", $path) as $ndx) {
$temp = isset($temp[$ndx]) ? $temp[$ndx] : null;
}
return $temp;
}
function keyset(&$arr, $keypath, $value = NULL)
{
$keys = explode('.', $keypath);
$current = &$arr;
while(count($keys))
{
$key = array_shift($keys);
if(!isset($current[$key]) && count($keys))
{
$current[$key] = array();
}
if(count($keys))
{
$current = &$current[$key];
}
}
$current[$key] = $value;
}
function keyget($arr, $keypath)
{
$keys = explode('.', $keypath);
$current = $arr;
foreach($keys as $key)
{
if(!isset($current[$key]))
{
return NULL;
}
$current = $current[$key];
}
return $current;
}
//Testing code:
$r = array();
header('content-type: text/plain; charset-utf8');
keyset($r, 'this.is.path', 39);
echo keyget($r, 'this.is.path');
var_dump($r);
It's a little rough, I can't guarantee it functions 100%.
Edit: At first you'd be tempted to try to use variable variables, but I've tried that in the past and it doesn't work, so you have to use functions to do it. This works with some limited tests. (And I just added a minor edit to remove an unnecessary array assignment.)
In the meanwhile, I came up with (another) solution:
private function setValueForKeyPath(&$array, $value, $keyPath)
{
$keys = explode(".", $keyPath, 2);
$firstKey = $keys[0];
$remainingKeys = (count($keys) == 2) ? $keys[1] : null;
$isLeaf = ($remainingKeys == null);
if ($isLeaf)
$array[$firstKey] = $value;
else
$this->setValueForKeyPath($array[$firstKey], $value, $remainingKeys);
}
Sorry for the "long" namings, I came from the Objective-C world. :)
So calling this on each keyPath, it actually gives me the output:
fields
Array
(
[0] => ID
[1] => UUID
[2] => pushNotifications.sent
[3] => campaigns.boundDate
[4] => campaigns.endDate
[5] => campaigns.pushMessages.endDate
[6] => pushNotifications.tapped
)
dissectedFields
Array
(
[ID] => 1
[UUID] => 1
[pushNotifications] => Array
(
[sent] => 1
[tapped] => 1
)
[campaigns] => Array

[endDate] => 1
[pushMessages] => Array
(
[endDate] => 1
)
)
)
Consider following array
$details = array(
array('lname'=>'A', 'fname'=>'P','membkey'=>700,'head'=>'y'),
array('lname'=>'B', 'fname'=>'Q','membkey'=>540,'head'=>'n'),
array('lname'=>'C', 'fname'=>'R','membkey'=>700,'head'=>'n'),
array('lname'=>'D', 'fname'=>'S','membkey'=>540,'head'=>'y'),
array('lname'=>'E', 'fname'=>'T','membkey'=>700,'head'=>'n')
);
Here I would like to sort with head and membkey. Top element of same membkey element should have 'head=y' and echoed as,
$details = array(
array('lname'=>'A', 'fname'=>'P','membkey'=>700,'head'=>'y'),
array('lname'=>'E', 'fname'=>'T','membkey'=>700,'head'=>'n'),
array('lname'=>'C', 'fname'=>'R','membkey'=>700,'head'=>'n'),
array('lname'=>'D', 'fname'=>'S','membkey'=>540,'head'=>'y'),
array('lname'=>'B', 'fname'=>'Q','membkey'=>540,'head'=>'n')
);
I tried it as follows
function orderbymemberKey( $a, $b ){
if ( $a[membkey] == $b[membkey] )
return 0;
return($a[membkey] < $b[membkey] )? -1 :1;
}
usort( $details, orderbymemberKey );
and it successfully order by membkey.
Any suggestions please.
You're half way there (though you were sorting backwards for membkey based on your example):
function order_by_member_key($a, $b)
{
if ($a['membkey'] == $b['membkey'])
{
// membkey is the same, sort by head
if ($a['head'] == $b['head']) return 0;
return $a['head'] == 'y' ? -1 : 1;
}
// sort the higher membkey first:
return $a['membkey'] < $b['membkey'] ? 1 : -1;
}
usort($details, "order_by_member_key");
Is this array being pulled from a database? Because, if so, you should be able to make use of ORDER BY clauses to clean it up outside of php.
<?php
$membkey = array();
$head = array();
foreach ($details as $key => $row) {
$membkey[$key] = $row['membkey'];
$head[$key] = $row['head'];
}
array_multisort($membkey, SORT_DESC, $head, SORT_DESC, $details);
print_r($details);
Or, an even more generic solution:
function sort_by($array) {
$arguments = func_get_args();
$array = array_pop($arguments);
$variables = array();
foreach ($arguments as $index => $key) {
$variables[] = '$arguments['.$index.']';
if ($index % 2 == 0) {
$arguments[$index] = array();
foreach ($array as $row) $arguments[$index][] = $row[$key];
}
}
// call_user_func_array will not work in this case
eval('array_multisort('.implode(', ', $variables).', $array);');
return $array;
}
print_r(sort_by('membkey', SORT_DESC, 'head', SORT_DESC, $details));
Ugly but someone wrote a function on php.net:
http://php.net/manual/en/function.sort.php
<?php
$array[0]['name'] = 'Chris';
$array[0]['phone'] = '3971095';
$array[0]['year'] = '1978';
$array[0]['address'] = 'Street 1';
$array[1]['name'] = 'Breanne';
$array[1]['phone'] = '3766350';
$array[1]['year'] = '1990';
$array[1]['address'] = 'Street 2';
$array[2]['name'] = 'Dusty';
$array[2]['phone'] = '1541120';
$array[2]['year'] = '1982';
$array[2]['address'] = 'Street 3';
function multisort($array, $sort_by, $key1, $key2=NULL, $key3=NULL, $key4=NULL, $key5=NULL, $key6=NULL){
// sort by ?
foreach ($array as $pos => $val)
$tmp_array[$pos] = $val[$sort_by];
asort($tmp_array);
// display however you want
foreach ($tmp_array as $pos => $val){
$return_array[$pos][$sort_by] = $array[$pos][$sort_by];
$return_array[$pos][$key1] = $array[$pos][$key1];
if (isset($key2)){
$return_array[$pos][$key2] = $array[$pos][$key2];
}
if (isset($key3)){
$return_array[$pos][$key3] = $array[$pos][$key3];
}
if (isset($key4)){
$return_array[$pos][$key4] = $array[$pos][$key4];
}
if (isset($key5)){
$return_array[$pos][$key5] = $array[$pos][$key5];
}
if (isset($key6)){
$return_array[$pos][$key6] = $array[$pos][$key6];
}
}
return $return_array;
}
//usage (only enter the keys you want sorted):
$sorted = multisort($array,'year','name','phone','address');
print_r($sorted);
//output:
