Convert associative array into indexed

Convert associative array into indexed - php

Ive seen a few examples by using array_values, but cant quite make out how to get it to work...
I have an associative array thats passed via POST, I need to convert it into a indexed array...
My print_r($_POST) gives me this... I need all of this put into an indexed array :)
Array (
[fieldnames] => 36771X21X198|36771X21X199|36771X21X200|36771X21X201|36771X21X202
[36771X21X198] => 3434343
[display36771X21X198] => on
[36771X21X199] => 5656565
[display36771X21X199] => on
[36771X21X200] => 89898989
[display36771X21X200] => on
[36771X21X201] => 90909090
[display36771X21X201] => on
[36771X21X202] => 12121212
[display36771X21X202] => on
[move] => movesubmit
[move2] => ONLINE Submit
[thisstep] => 1
[sid] => 36771
[token] => 1234567890
)

Observe this amazing way to convert your $_POST into a numerically indexed array:
$numerical = array_values($_POST);
but what if you want to preserve your keys? Perhaps you want something like this?
$numerical = array();
$sep = ':';
foreach($_POST as $k=>$v)
{
$numerical[] = $k.$sep.$v;
}
$numerical will then have:
Array
(
[0] => fieldnames:36771X21X198|36771X21X199|36771X21X200|36771X21X201|36771X21X202
[1] => 36771X21X198:3434343
[2] => display36771X21X198:on
[3] => 36771X21X199:5656565
[4] => display36771X21X199:on
[5] => 36771X21X200:89898989
[6] => display36771X21X200:on
[7] => 36771X21X201:90909090
[8] => display36771X21X201:on
[9] => 36771X21X202:12121212
[10] => display36771X21X202:on
[11] => move:movesubmit
[12] => move2:ONLINE Submit
[13] => thisstep:1
[14] => sid:36771
[15] => token:1234567890
)
or, for my final example:
$fieldnames_original = explode('|', $_POST['fieldnames']);
$fieldnames_actual = array();
$values = array();
foreach($_POST as $k=>$v)
{
if($k!='fieldnames')
{
$fieldnames_actual[] = $k;
$values[] = $v;
}
}
which will set 3 arrays:
$fieldnames_original:
Array
(
[0] => 36771X21X198
[1] => 36771X21X199
[2] => 36771X21X200
[3] => 36771X21X201
[4] => 36771X21X202
)
$fieldnames_actual:
Array
(
[0] => 36771X21X198
[1] => display36771X21X198
[2] => 36771X21X199
[3] => display36771X21X199
[4] => 36771X21X200
[5] => display36771X21X200
[6] => 36771X21X201
[7] => display36771X21X201
[8] => 36771X21X202
[9] => display36771X21X202
[10] => move
[11] => move2
[12] => thisstep
[13] => sid
[14] => token
)
and $values:
Array
(
[0] => 3434343
[1] => on
[2] => 5656565
[3] => on
[4] => 89898989
[5] => on
[6] => 90909090
[7] => on
[8] => 12121212
[9] => on
[10] => movesubmit
[11] => ONLINE Submit
[12] => 1
[13] => 36771
[14] => 1234567890
)

function
function array_default_key($array) {
$arrayTemp = array();
$i = 0;
foreach ($array as $key => $val) {
$arrayTemp[$i] = $val;
$i++;
}
return $arrayTemp;
}
Pass the associative array as a parameter and it will convert into the default index of the array. For example: we have Array('2014-04-30'=>43,'2014-04-29'=>41) after the call to the function the array will be Array(0=>43,1=>41).

Recursive assoc to indexed converter tested on a small array.
function assoc2indexedMulti($arr) {
// initialize destination indexed array
$indArr = array();
// loop through source
foreach($arr as $val) {
// if the element is array call the recursion
if(is_array($val)) {
$indArr[] = assoc2indexedMulti($val);
// else add the value to destination array
} else {
$indArr[] = $val;
}
}
return $indArr;
}

how to array push with multidimension in php

I have an array in PHP loop output like this
this is my php code :
$sql = "SELECT * FROM `acc` ";
$stm = $conn->prepare($sql);
$stm->execute();
$array= [];
while ($row = $stm->fetch(PDO::FETCH_ASSOC)) {
$array[]=$row['h_id'];
}
print_r($array);
and output is :
Array

[1] => 12
[2] => 13
[3] => 1101
[4] => 1102
[5] => 110101

)
and I want to sort and rearrange array to multi-dimension for parent and child with php Loop Like this :

how to implemention and push array to another with php.
thanks!

I absolutely don't understand what you're doing, but I think I've grasped how your input may be mapped to desired output. Here is the code:
<?php
$flat = [
11,
12,
13,
1101,
1102,
110101,
110102,
1201,
1202,
1301,
1302,
1303,
130201,
130202,
130301,
130302,
];
function expand($flat)
{
$expanded = [];
foreach ($flat as $element) {
$sections = str_split((string)$element, 2);
$tmp = &$expanded;
$path = '';
foreach ($sections as $section) {
$path .= $section;
if (!isset($tmp[$path])) {
$tmp[$path] = [];
}
$tmp =& $tmp[$path];
}
unset($tmp);
}
return $expanded;
}
function fold($expanded) {
$folded = [];
foreach ($expanded as $key => $value) {
if ($value === []) {
$folded[] = $key;
} else {
$folded[$key] = fold($value);
}
}
return $folded;
};
print_r(fold(expand($flat)));
And here is its output (which is suspiciously close to yours):
Array
(
[11] => Array
(
[1101] => Array
(
[0] => 110101
[1] => 110102
)
[1102] => 1102
)
[12] => Array
(
[0] => 1201
[1] => 1202
)
[13] => Array
(
[0] => 1301
[1302] => Array
(
[0] => 130201
[1] => 130202
)
[1303] => Array
(
[0] => 130301
[1] => 130302
)
)
)
There are some differences, though, e.g. there is element 1102 in your input, but in your sample output it is absent, and I'm not sure if you forgot it or if you have filtered it out for some reason.

This is what I have tried:
$tmp = array();
foreach($arrayName as $arg){
$tmp[$arg['package']][] = $arg['value'];
}
$output = array();
foreach($tmp as $type => $labels){
$output[] = array( 'package' => $type, 'value' => $labels, );
}
print_r(($output))

Try this:
foreach ($your_array as $subarr) {
echo $subarr[package]." minimum = ";
echo min($subarr[value])." and maximum = ";
echo max($subarr[value])."<br>";
}
this will output each package name together with the minimum and maximum values.

Simply use the min() and max() functions.
Your code:
foreach(array_column($array, 'value') as $key => $values){
echo PHP_EOL . 'SubArray '. $key .' min = '. min($values) . ' and max value = '. max($values);
}
output is:
SubArray 0 min = 5 and max value = 3356143
SubArray 1 min = 1 and max value = 2764815

#Arebhy Sri, You should search about array in php, It's like basic problem.
$finalArray = [];
foreach ($mainArr as $subArr){
$array = $subArr['value'];
sort($array);
$tempArray['minimum'] = reset($array);
$tempArray['maximum'] = end($array);
$tempArray['package'] = $subArr['package'];
$finalArray[] = $tempArray;
}
$finalArray //you can use
I am using simple foreach and two functions of array reset() and end().
reset(): Returns the value of the first array element, or FALSE if the array is empty.
end(): Returns the value of the last element or FALSE for empty array.

get count of entries in multi-dimensional array with comma separated values- php

How to get count of entries in an array below?
I tried Count arrays comma separated values and didnot get desired solution.Please suggest a method.
For below sample count is 11.
$sample= Array (
[0] => Array (
[0] => Array ( [attendance] => 2012SD71,2010SD94 )
[1] => Array ( [attendance] => 2003SD18,2003SD19 )
[2] => Array ( [attendance] => 2003SD23,2003SD28 ))
[1] =>
[2] =>
[3] =>
[4] =>
[5] =>
[6] =>
[7] =>
[8] =>
[9] =>
[10] =>
[11] =>
[12] =>
[13] => Array (
[0] => Array ( [attendance] => 2012SD81,2010SD84 )
[1] => Array ( [attendance] => 2003SD18,2003SD19,2004SD14 ) ) [14] =>
[15] =>
);

A simple recursive function should work that uses explode() and array_merge():
function recurse($array,&$new)
{
foreach($array as $key => $value) {
if(is_array($value)) {
recurse($value,$new);
}
else {
if(!empty($value)) {
$exp = array_filter(explode(',',$value));
$new = array_merge($new,$exp);
}
}
}
}
# Create a storage array
$new = array();
# Run the recursive function
recurse($sample,$new);
# Show count
print_r(count($new));

Multidimensional Array Listing Printing Php

You can do it like this:
<?php
// Dummy data source
$data = array(
'/do-update.php',
'/sitemap.xml',
'/sitemap.xml.gz',
'/wp-config.php',
array(
array(
array(
'/wp-content/uploads/2013/05/kabeduvarkad-1024x768.jpg',
'/wp-content/uploads/2013/05/kabeduvarkad-150x150.jpg',
'/wp-content/uploads/2013/05/kabeduvarkad-300x225.jpg<br>'
)
)
)
);
// Helper function
function getFiles($data, &$fileList) {
foreach ($data as $dataItem) {
if (is_array($dataItem))
getFiles($dataItem, $fileList);
else
$fileList[] = $dataItem;
}
}
// Debug
echo "<b>Orignal Array</b>";
var_dump($data);
echo "<hr>";
// Helper function usage
echo "<b>Parsed Array</b>";
$fileList = array();
getFiles($data, $fileList);
var_dump($fileList);
?>
Output:

Ok use this function its working
$all=array();
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
foreach($it as $v) {
$all[]=$v;
}
print_r($all);

With $var[] = you basically say that you want to add a new Element to $var with an incremented key.
Your Recursive frunction returns an array.
So this array is assigned as a new element in your array.
But what you want is a flat array.
Instead of adding an array to your array like this:
if (is_array($v)){
$result[] = listArrayRecursive($v, $ident.'/'.$k);
Merge the existing arrays like this:
if (is_array($v)){
$tmpResult = listArrayRecursive($v, $ident.'/'.$k);
$result = array_merge($result, $tmpResult);
You can see a working example here.

Shuffle inside array php

how to shuffle arrays in array ? I tried lots of way but I can't achieve that. I think it's very simple but I'm stuck on that.
Array
(
[2] => Array
(
[0] => 12011190
[1] => 12011158
[2] => 12011583
[3] => 12012107
[4] => 12011222
[5] => 12010638
[6] => 12013836
[7] => 12012232
[8] => 12011256
[9] => 12010007
[10] => 12012531
[11] => 12012182
[12] => 12013253
)
[6] => Array
(
[0] => 12011565
[1] => 12010020
[2] => 12011352
[3] => 12014366
[4] => 12011879
[5] => 12011449
)
)
I want to shuffle within arrays. I hope explain...

As far as I know, you can do it like this (assuming you want to shuffle every sub-array independently):
foreach($array AS &$element) {
shuffle($element);
}
Or maybe like this:
array_walk($array, function(&$value, $key) {
shuffle($value);
});

Here is a recursive multi-level function you can use.
function shuffle_array($arr) {
if (!is_array($arr)) return $arr;
shuffle($arr);
foreach ($arr as $key => $a) {
if (is_array($a)) {
$arr[$key] = shuffle_array($a);
}
}
return $arr;
}
print_r(shuffle_array($array));
