array_combine() expects parameter 2 to be array, string given in php - php

Array
(
[0] => tttt
[1] => tttt
)
$terms_keys = array("terms");
$terms_array = array();
foreach ( array_map(null,$inv_terms) as $key => $value ) {
$terms_array[] = array_combine($terms_keys, $value);
}
what is mistake done in my code ?

The $value param in the foreach is of course not an array its a scalar tttt, so you could make it into an array by doing [$value] in the combine
$terms_keys = array("terms");
$terms_array = array();
foreach ( array_map(null,$inv_terms) as $key => $value ) {
$terms_array[] = array_combine($terms_keys, [$value]);
}
Or simplified as the array_map() does not achieve anything
$terms_keys = array("terms");
$terms_array = array();
foreach ( $inv_terms as $key => $value ) {
$terms_array[] = array_combine($terms_keys, [$value]);
}

I don't understand how it could be advantageous to bloat your array structure with more depth, but generating the indexed array of associative arrays can be done without iterated function calls. Just push the values into their new deep location using square-brace pushing syntax in a body-less foreach loop.
Code: (Demo)
$inv_terms = ['tttt', 'tttt'];
$result = [];
foreach ($inv_terms as $result[]['terms']);
var_export($result);
Output:
array (
0 =>
array (
'terms' => 'tttt',
),
1 =>
array (
'terms' => 'tttt',
),
)

PHP Puttin values of array into multidimensional array

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();
}

array conversion with in array PHP

i need to convert bellow array from
Array
(
[Property] => Array
(
[S] => Built As Condominium
)
)
to
Array
(
[property] => Built As Condominium
)
is their any way.
You could use an implode under a foreach
<?php
$arr=Array ( 'Property' => Array ( 'S' => 'Built As Condominium' ) );
foreach($arr as $k=>$arr1)
{
$arr[$k]=implode('',$arr1);
}
print_r($arr);
Demo
you can use the key of the array to implode the value in one line for example
$array['Property'] = $array['Property']['S'];
Results
Array ( [property] => Built As Condominium )
$data = array(
"Property" => array(
"S" => "Built As Condominium"
)
);
foreach($data as $key => $value) {
if($key == "Property") {
$normalized_data['Property'] = is_array($value) && isset($value['S']) ? $value['S'] : NULL;
}
}
Program Output
array(1) {
["property"]=>
string(20) "Built As Condominium"
}
Link
Implode is not necessary, or keys, just use a reference, i.e. the '&'. This is nice and simple.
$array = Array ( 'Property' => Array ( 'S' => 'Built As Condominium' ) );
foreach($array as &$value){
$value=$value['S'];
}
or.... if you don't know the key of the inner array but only care about its value (and assuming you want the first member of the inner array as your new value) then something like reset inside a foreach loop would work:
$arr = array ('Property' => array( 'S' => 'Built As Condominium'));
$new = array();
foreach($arr as $key => $inner) {
$new[$key] = reset($inner);
}
print_r($new);
output:
Array
(
[Property] => Built As Condominium
)

Converting multidimensional array's values into a key value pair in a one-dimensional array while taking out a prefix out of one of the values?

I have an array in the following format:
Array (
[0] => Array
(
[option_id] => 10820
[option_name] => PREFIX_FIRST_OPT_KEY
[option_value] => FIRST_OPT_VALUE
[autoload] => yes
)
[1] => Array
(
[option_id] => 10821
[option_name] => PREFIX_SECOND_OPT_KEY
[option_value] => SECOND_OPT_VALUE
[autoload] => yes
)
[2] => Array
(
[option_id] => 10824
[option_name] => PREFIX_THIRD_OPT_KEY
[option_value] => SECOND_OPT_VALUE
[autoload] => yes
)
)
What is the appropriate function to use to get a one dimensional associative array with the following structure?
Array (
[FIRST_OPT_KEY] => FIRST_OPT_VALUE
[SECOND_OPT_KEY] => SECOND_OPT_VALUE
[THIRD_OPT_KEY] => THIRD_OPT_VALUE
)
I only want to keep the indicated values as key value pairs in the new array and ignore the rest - PREFIX_ is fixed length.
What I am doing right now:
foreach ( $the_original_array as $key => $value ) {
$new_key = substr($the_original_array[$key]['option_name'], 7);
$option_value = $the_original_array[$key]['option_value'];
$new_array[$new_key] = $option_value;
}
but I feel there ought to be a cleaner/more efficient way of accomplishing this
If you have PHP >= 5.5:
To extract values:
$result = array_column($array, 'option_value', 'option_name');
Then to remove prefix:
$result = array_combine(
array_map(
function($k){
return str_replace('PREFIX_', '', $k);
},
array_keys($result)
), $result
);
A way of simulating array_column() if you aren't running PHP 5.5+
$newArray = array_combine(
array_map(
function($value) {
return substr($value['option_name'], 7);
},
$the_original_array
),
array_map(
function($value) {
return $value['option_value'];
},
$the_original_array
)
);
The accepted answer is valid, but it causes the data to be iterated over multiple times. Assuming PHP < 5.5.0, using array_reduce will loop over the data only once, and return the same result:
$iterator = function($result, $record) {
$key = substr($record['option_name'], 7);
$result[$key] = $record['option_value'];
return $result;
};
$newArray = array_reduce($original, $iterator, array());
I would use array_column but for PHP < 5.5.0 what you have is about the best you can do, but you can use the $value that is generated by the foreach:
foreach ( $the_original_array as $value ) {
$new_key = substr($value['option_name'], 7);
$option_value = $value['option_value'];
$new_array[$new_key] = $option_value;
}
I think than foreach is good like:
$new = array();
foreach ($original_array as $item) {
$index = str_replace('PREFIX_', '', $item['option_name']);
$new[$index] = $item['option_value'];
}

Replace key of array with the value of another array while looping through

I have two multidimensional arrays. First one $properties contains english names and their values. My second array contains the translations. An example
$properties[] = array(array("Floor"=>"5qm"));
$properties[] = array(array("Height"=>"10m"));
$translations[] = array(array("Floor"=>"Boden"));
$translations[] = array(array("Height"=>"Höhe"));
(They are multidimensional because the contains more elements, but they shouldn't matter now)
Now I want to translate this Array, so that I its at the end like this:
$properties[] = array(array("Boden"=>"5qm"));
$properties[] = array(array("Höhe"=>"10m"));
I have managed to build the foreach construct to loop through these arrays, but at the end it is not translated, the problem is, how I tell the array to replace the key with the value.
What I have done is this:
//Translate Array
foreach ($properties as $PropertyArray) {
//need second foreach because multidimensional array
foreach ($PropertyArray as $P_KiviPropertyNameKey => $P_PropertyValue) {
foreach ($translations as $TranslationArray) {
//same as above
foreach ($TranslationArray as $T_KiviTranslationPropertyKey => $T_KiviTranslationValue) {
if ($P_KiviPropertyNameKey == $T_KiviTranslationPropertyKey) {
//Name found, save new array key
$P_KiviPropertyNameKey = $T_KiviTranslationValue;
}
}
}
}
}
The problem is with the line where to save the new key:
$P_KiviPropertyNameKey = $T_KiviTranslationValue;
I know this part is executed correctly and contains the correct variables, but I believe this is the false way to assing the new key.
This is the way it should be done:
$properties[$oldkey] = $translations[$newkey];
So I tried this one:
$PropertyArray[$P_KiviPropertyNameKey] = $TranslationArray[$T_KiviTranslationPropertyKey];
As far as I understood, the above line should change the P_KiviPropertyNameKey of the PropertyArray into the value of Translation Array but I do not receive any error nor is the name translated. How should this be done correctly?
Thank you for any help!

(
[arable_no_flag] => Ei peltoa
[group] => Kohde
)
[3] => Array
(
[arableland] => Pellon kuvaus
[group] => Kohde
)
)
I can build the translations array in another way. I did this like this, because in the second step I have to check, which group the keys belong to...
Try this :
$properties = array();
$translations = array();
$properties[] = array("Floor"=>"5qm");
$properties[] = array("Height"=>"10m");
$translations[] = array("Floor"=>"Boden");
$translations[] = array("Height"=>"Höhe");
$temp = call_user_func_array('array_merge_recursive', $translations);
$result = array();
foreach($properties as $key=>$val){
foreach($val as $k=>$v){
$result[$key][$temp[$k]] = $v;
}
}
echo "<pre>";
print_r($result);
output:
Array
(
[0] => Array
(
[Boden] => 5qm
)
[1] => Array
(
[Höhe] => 10m
)
)
Please note : I changed the array to $properties[] = array("Floor"=>"5qm");, Removed a level of array, I guess this is how you need to structure your array.
According to the structure of $properties and $translations, you somehow know how these are connected. It's a bit vague how the indices of the array match eachother, meaning the values in $properties at index 0 is the equivalent for the translation in $translations at index 0.
I'm just wondering why the $translations array need to have the same structure (in nesting) as the $properties array. To my opinion the word Height can only mean Höhe in German. Representing it as an array would suggest there are multiple translations possible.
So if you could narrow down the $translations array to an one dimensional array as in:
$translation = array(
"Height"=>"Höhe",
"Floor"=>"Boden"
);
A possible loop would be
$result = array();
foreach($properties as $i => $array2) {
foreach($array2 as $i2 => $array3) {
foreach($array3 as $key => $value) {
$translatedKey = array_key_exists($key, $translations) ?
$translations[$key]:
$key;
$result[$i][$i2][$translatedKey] = $value;
}
}
}
(I see every body posting 2 loops, it's an array,array,array structure, not array,array ..)
If you cannot narrow down the translation array to a one dimensional array, then I'm just wondering if each index in the $properties array matches the same index in the $translations array, if so it's the same trick by adding the indices (location):
$translatedKey = $translations[$i][$i2][$key];
I've used array_key_exists because I'm not sure a translation key is always present. You have to create the logic for each case scenario yourself on what to check or not.
This is a fully recursive way to do it.
/* input */
$properties[] = array(array("Floor"=>"5qm", array("Test"=>"123")));
$properties[] = array(array("Height"=>"10m"));
$translations[] = array(array("Floor"=>"Boden", array("Test"=>"Foo")));
$translations[] = array(array("Height"=>"Höhe"));
function array_flip_recursive($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_flip_recursive($val);
}
else {
$arr = #array_flip($arr);
}
}
return $arr;
}
function array_merge_it($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_merge_it($val);
} else {
if(isset($arr[$key]) && !empty($arr[$key])) {
#$arr[$key] = $arr[$val];
}
}
}
return $arr;
}
function array_delete_empty($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_delete_empty($val);
}
else {
if(empty($arr[$key])) {
unset($arr[$key]);
}
}
}
return $arr;
}
$arr = array_replace_recursive($properties, $translations);
$arr = array_flip_recursive($arr);
$arr = array_replace_recursive($arr, $properties);
$arr = array_merge_it($arr);
$arr = array_delete_empty($arr);
print_r($arr);

You have to do the for loop in this way. If i understood you right (i.e) in associative array first key is same (some index).
foreach($properties as $key => $values) {
foreach($values as $key1 => $value1) {
$propertyResult[] = array($translations[$key][$key1][$value1] => $properties[$key][$key1][$value1]);
}
}
print_r($propertyResult);

How do I invert a multi-dimensional array?

I have an array with n elements in it, with each element containing n child elements, each containing...
Array
(
[tea] => Array
(
[drink] => Array
(
[food] =>
)
)
[biscuits] => Array
(
[snack] => Array
(
[food] =>
)
)
...
)
What I want to do is have the inner most element on the outside, and the outer most elements on the inside:
Array
(
[food] => Array
(
[drink] => Array
(
[tea] =>
)
[snack] => Array
)
[biscuits] =>
(
)
...
)
And the solution needs to be able to deal with n children arrays. I am aware of How do I invert a multidimensional array in PHP but the solutions there did not solve this problem.
I'm pretty sure this could be condensed further, but it does the job:
function flatten(array $array) {
$key = array(key($array));
$val = current($array);
if (is_array($val)) {
$key = array_merge(flatten($val), $key);
}
return $key;
}
function build(array $path, array $result) {
$key = array_shift($path);
if (!isset($result[$key])) {
$result[$key] = $path ? array() : null;
}
if ($path) {
$result[$key] = build($path, $result[$key]);
}
return $result;
}
$result = array();
foreach ($array as $key => $value) {
$result = build(flatten(array($key => $value)), $result);
}
