i have a html form in which i use array like this (name="courts[]"). when it send data to php file i use foreeach loop to create multidimensional array for inserting records in mysql. In php file i write foreeach loop to iterate like this
$data = array();
$i = 0;
foreach ($court_name as $result)
{
$data[] = array(
'court_name' => $result[0]
);
$i++;
}
it display result this
Array
(
[0] => Array
(
[court_name] => P
)
[1] => Array
(
[court_name] => S
)
)
instead of this
Array
(
[0] => Array
(
[court_name] => Punjab
)
[1] => Array
(
[court_name] => Sindh
)
)
(referring the outputs) in your loop, $result contains court name. So if you use $result[0], you get first character of string.
Try this:
foreach ($court_name as $result)
{
$data[] = array(
'court_name' => $result
);
$i++;
}
foreach loop gives you one element of array ($result) now you access to the first character of value via $result[0], change it to $result
foreach ($court_name as $result) {
$data[] = array( 'court_name' => $result );
}

I have this array:
[docs] => Array
(
[indexone] => Array ( [0] => P008062518 )
[indextwo] => Array ( [0] => )
[indexthree] => Array ( [0] => 0000141334 )
[indexfour] => Array ( [0] => P006871638 )
[indexfive] => Array ( [0] => 0000910067 )
[indexsix] => Array ( [0] => )
)
I need to end with this one, extracting all values from the given key:
[docValues] => Array
(
[indexone] => Array ( P008062518, 0000141334, P006871638, 0000910067 )
)
I try this loop but i end with the same array structure :
foreach($values as $key => $data)
{
if(array_key_exists('docs', $data) )
{
$filtered = array_filter($data['docs'], function($var) { return !empty($var);});
$numDocs = array_values($filtered);
$values[$key]['docValues'] = $numDocs;
}
}
How can it be done ?
To get that exact array output:
$result['docValues'][key($values['docs'])] =
array_filter(array_column($values['docs'], 0));
Get the first key to use it as your new key with key()
Get an array of all values in the 0 indexes with array_column()
Remove empty elements using array_filter()
If your first array is called $docArray, then you can do the following:
$docValuesArray = array();//declaring the result array
$indexoneArray = array();//declaring the array you will add values
//to in the foreach loop
foreach ($docArray as $value)
{
$indexoneArray[] = $value[0];//giving each of the values
//found in $docArray to the $indexoneArray
}
$docValueArray[] = $indexoneArray;//adding the $indexoneArray
//to the $docsValueArray
Let me know if that worked for you.
This should do the trick for you:
$docs = [
'indexone' => ['P008062518'],
'indextwo' => [ ],
'indexthree' => ['0000141334'],
'indexfour' => ['P006871638'],
'indexfive' => ['0000910067'],
'indexsix' => [ ],
];
$allDocs = array();
foreach($docs as $key => $doc) {
$docString = implode("<br>",$doc);
if (empty($docString)) {
continue;
}
$allDocs[] = $docString;
}
$allDocsString = implode("<br>",$allDocs);
echo($allDocsString);
P0080625180000141334P0068716380000910067
Simply do this:
Your array
$arr = array("docs" =>
array(
'indexone' => array('P008062518'),
'indextwo' => array(''),
'indexthree' => array('0000141334'),
'indexfour' => array('P006871638'),
'indexfive' => array('0000910067'),
'indexsix' => array('')
)
);
Process:
echo '<pre>';
$index = key($arr["docs"]);
$output['docValues'][$index] = implode('<br/>', array_filter(array_column($arr['docs'], 0)));
print_r($output);
Explanation:
key = key function Returns the first index.
implode = collapse all the array items with the delimiter of <br/>
array_filter = filters the values of an array using a callback
function.
array_column = returns the values from a single column in the input
array.
Result:
Array
(
[docValues] => Array
(
[indexone] => P008062518<br/>0000141334<br/>P006871638<br/>0000910067
)
)
use array_filter() function . if you pass array in array_filter then remove all empty and NULL data record
Hello I want to put values of single array into a multidimensional array with each value on a n+1
This is my array $structures
Array
(
[0] => S
[1] => S.1
[2] => S-VLA-S
[3] => SB
[4] => SB50
)
What I want for output is this
Array
(
[S] => Array(
[S.1] => Array (
[S-VLA-S] => Array (
[SB] => Array (
[SB50] => Array(
'more_attributes' => true
)
)
)
)
)
)
This is what I have tried so far
$structures = explode("\\", $row['structuurCode']);
foreach($structures as $index => $structure) {
$result[$structure][$structure[$index+1]] = $row['structuurCode'];
}
The values of the array is a tree structure that's why it would be handy to have them in an multidimensional array
Thanks in advance.
It becomes pretty trivial once you start turning it inside out and "wrap" the inner array into successive outer arrays:
$result = array_reduce(array_reverse($structures), function ($result, $key) {
return [$key => $result];
}, ['more_attributes' => true]);
Obviously a more complex solution would be needed if you needed to set multiple paths on the same result array, but this is the simplest solution for a single path.
Slightly different approach:
$var = array('a','an','asd','asdf');
$var2 = array_reverse($var);
$result = array('more_attributes' => true);
$temp = array();
foreach ($var2 as $val) {
$temp[$val] = $result;
$result = $temp;
$temp = array();
}
I want to convert multi dimensional array in Php
I'm stuck in logic.. Kindly help
Thanks in advance
Current Produced array :
Array
(
[5316] => Array
(
[0] => Array
(
[PROD1] => color=black
)
[1] => Array
(
[PROD1] => paper=a1
)
[2] => Array
(
[PROD2] => color=metallic_silver
)
[3] => Array
(
[PROD2] => paper=a1
)
)
)
I want to convert this array into this form
Array
(
[5316] => Array
(
[PROD1] => Array
(
color => black
paper => a1
)
[PROD2] => Array
(
color => metallic_silver
paper => a1
)
)
)
If you can't hardcode that key to directly point to it, you can use reset() in this case, then grouped them inside a foreach accordingly. Example:
$array = array(
5316 => array(
array('PROD1' => 'color=black'),
array('PROD1' => 'paper=a1'),
array('PROD2' => 'color=metallic_silver'),
array('PROD2' => 'paper=a1'),
),
);
$grouped = array();
// point it to the first key which gives an array of those values
foreach (reset($array) as $key => $value) {
reset($value); // reset the internal pointer of the sub array
$key = key($value); // this return `PROD1, PROD2`
$grouped[$key][] = current($value); // current gives color=black, the values
}
$array[key($array)] = $grouped; // then reassign
echo '<pre>';
print_r($array);
Sample Output
You can try something like below.
$newArr = [];
$count = count($arr[5316]);
for($i = 0, $j = 1; $i < $count; $i += 2){
$color = explode('=', $arr[5316][$i]['PROD'.$j]);
$paper = explode('=', $arr[5316][$i+1]['PROD'.$j]);
$newArr[5316]['PROD'.$j] = array('color'=>$color[1], 'paper'=>$paper[1]);
$j++;
}
//To show output
print '<pre>';
print_r($newArr);
print '</pre>';
I am struggling with an array that I need to convert into a new array based on the unique array keys. My current result looks like below. Each array represent just a part of the desired result (pivot) where I need a [menu_name], [menu_url] and [menu_target] as result and when the next array begins with the same keys, etc. So the way I see it to achieve this is to construct a new array, each time an array_key_exist in the array. But i am unable to achieve this.
Array
(
Array
(
[menu_name] => Contact
)
Array
(
[menu_url] => /contact
)
Array
(
[menu_target] => _blank
)
Array
(
[menu_name] => Home
)
Array
(
[menu_url] => /home
)
Array
(
[menu_target] => _self
)
)
The desired array I want to create looks like this:
Array
(
[0] => Array
(
[menu_name] => Contact,
[menu_url] => /contact,
[menu_target] => _blank
)
[1] => Array
(
[menu_name] => Home,
[menu_url] => /home,
[menu_target] => _blank
)
)
Here is my code so far (incomplete):
$result = array();
foreach($array as $option => $value)
{
$result[$value->option_key] = $value->option_value;
$new_array = array();
if(array_key_exist($value->option_key, $new_array))
{
// here is where I get stuck….
print_r($new_array);
}
}
I hope some one can get me in the right direction to further complete the code with the desired result.
You can use a var you increment each time key already exists :
$result = array();
$i = 0;
foreach($array as $option => $value)
{
if ( array_key_exists($value->option_key, $result[$i]) ) $i++;
$result[$i][$value->option_key] = $value->option_value;
}
Another way, is if the current batch of keys are complete, go to the next one and fill up the next one. Example:
$values = array(array('menu_name' => 'Contact'),array('menu_url' => '/contact'),array('menu_target' => '_blank'),array('menu_name' => 'Home'),array('menu_url' => '/home'),array('menu_target' => '_self'),);
$new_values = array();
$x = 0;
$columns = array_unique(array_map(function($var){
return key($var);
}, $values));
foreach($values as $value) {
$current_key = key($value);
$new_values[$x][$current_key] = reset($value);
if(array_keys($new_values[$x]) == $columns) $x++;
}
echo '<pre>';
print_r($new_values);
Sample Demo
Provided your answer is always grouped by threes, as posted in your example.
This is an alternative method to djidi's answer incase you wanted to see it done with silly loops.
$new = array_chunk($a, 3);
$d = array();
foreach($new as $i => $group) {
foreach($group as $index => $item) {
foreach($item as $name=>$val) {
$d[$i][$name] = $val;
}
}
}
Which returns:
Array
(
[0] => Array
(
[menu_name] => Contact
[menu_url] => /contact
[menu_target] => _blank
)
[1] => Array
(
[menu_name] => Home
[menu_url] => /home
[menu_target] => _self
)
)
Example Demo
I'm trying to use a specific object type from a JSON feed, and am having a hard time specifying it. Using the code below I grab and print the specific array (max) I want,
$jsonurl = "LINK";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json,true);
$max_output = $json_output["max"];
echo '<pre>';
print_r($max_output);
echo '</pre>';
And from the Array below, all I want to work with is the [1] objects in each array. How can I specify and get just those values?
Array
(
[0] => Array
(
[0] => 1309924800000
[1] => 28877
)
[1] => Array
(
[0] => 1310011200000
[1] => 29807
)
[2] => Array
(
[0] => 1310097600000
[1] => 33345
)
[3] => Array
(
[0] => 1310184000000
[1] => 33345
)
[4] => Array
(
[0] => 1310270400000
[1] => 33345
)
[5] => Array
(
[0] => 1310356800000
[1] => 40703
)
Well you could fetch those values with array_map:
$max_output = array_map(function($val) { return $val[1]; }, $json_output["max"]);
This requires PHP 5.3, if you use an earlier version, then you can use create_function to achieve similar results:
$max_output = array_map(create_function('$val', 'return $val[1];'), $json_output["max"]);
When you need to create new array which will contain only second values, you may use either foreach loop which will create it or use array_map() (just for fun with anonymous function available since php 5.3.0):
$newArray = array_map( function( $item){
return $item[1]
},$array);
Then you want to use last ("max" -> considering array with numeric keys) item, you can use end():
return end( $item);
And when you can process your data sequentially (eg. it's not part of some big getData() function) you can rather use foreach:
foreach( $items as $key => $val){
echo $val[1] . " is my number\n";
}
After you get $max_output...
for( $i = 0; $i < length( $max_output ); $i++ ) {
$max_output[$i] = $max_output[$i][1];
}
try this:
$ones = array();
foreach ($max_output as $r)
$ones[] = $r[1];
