I have two array. array one and array two. I want to merge these array into single array with key. My output result is valid but sequence is not correct.
Array one
Array
(
[0] => test-685f1e7bc357187e449479d627100102
[1] => test-685f1e7bc357187e449479d627d29390
)
Array two
Array
(
[0] => DF955298-A664-4FA7-9586-FCD4CF977777
[1] => DF955298-A664-4FA7-9586-FCD4CF988888
)
Expected Result
Array
(
[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102
[uuid] => DF955298-A664-4FA7-9586-FCD4CF977777
)
[1] => Array
(
[key] => test-685f1e7bc357187e449479d627d29390
[uuid] => DF955298-A664-4FA7-9586-FCD4CF988888
)
)
My code is for that result is mentioned below:
$record = array();
foreach ($keys_array as $key => $all_key) {
foreach ($uuid_array as $uuid_key => $all_uuid) {
$record[$key]['key'] = $all_key;
$record[$uuid_key]['uuid'] = $all_uuid;
}
}
My output sequence is not valid. Where is the problem
Array
(
[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102
[uuid] => DF955298-A664-4FA7-9586-FCD4CF977777
)
[1] => Array
(
[uuid] => test-685f1e7bc357187e449479d627d29390
[key] => DF955298-A664-4FA7-9586-FCD4CF988888
)
)
Simple solution:
$record = array();
foreach ($keys_array as $key => $all_key) {
$record[] = [
'key' => $all_key,
// get value under the same key from `$uuid_array`
'uuid' => $uuid_array[$key],
];
}

But I Don't Know Ho To Get L Number By Value For Example I Have TL284394 And I Want To Know Level So It Will Show L11 How Can I Do It
you can use two foreach loop inside each other and array_search() like this:
$a = array("L1" => [ 0 => "TL422632" ],"L2"=> [ 0 => "TL422635" ]);
$x = "TL422635";
foreach($a as $key=>$value){
if($x === $value){
return $key;
}else{
foreach($value as $k=>$v){
if($x === $v){
return array_search([$k=>$v],$a);
}
}
}
}
I have an array like this:
Array
(
[0] => Array
(
[id] => 10
[field] => new
[value] => pqr
)
[1] => Array
(
[id] => 14
[field] => test
[value] => abc
)
[2] => Array
(
[id] => 17
[field] => test
[value] => xyz
)
)
Now I want to merge this array with field name with id and value will be comma separated. So my new array will look like:
Array
(
[0] => Array
(
[id] => 10
[field] => new
[value] => pqr
)
[1] => Array
(
[id] => 14,17
[field] => test
[value] => abc,xyz
)
)
Can we do this with any php inbuilt function.
I don't know of any built in function to do this, but it's pretty trivial with a simple foreach loop.
String Concatenation Approach
$new_array = [];
foreach($array1 as $arr) {
$field = $arr['field'];
$id = $arr['id'];
$value = $arr['value'];
//we use $field as $new_array keys so we can combine values
if(!array_key_exists($field, $new_array)) {
//key doesn't exist in new array, so create it
$new_array[$field] = $arr;
} else {
//key exists in new array, append new values
$new_array[$field]['id'] .= ",{$id}";
$new_array[$field]['value'] .= ",{$value}";
}
}
//reset array keys back to sequential
$new_array = array_values($new_array);
Output of $new_array would be
Array
(
[0] => Array
(
[id] => 10
[field] => new
[value] => pqr
)
[1] => Array
(
[id] => 14,17
[field] => test
[value] => abc,xyz
)
)
Normalized Array Approach
$new_array = [];
foreach($array1 as $arr) {
$field = $arr['field'];
$id = $arr['id'];
$value = $arr['value'];
//we use $field as $new_array keys so we can combine values
if(!array_key_exists($field, $new_array)) {
//key doesn't exist in new array, so create it
$new_array[$field] = ['id' => [$id], 'field' => $field, 'value' => [$value]];
} else {
//key exists in new array, append new values
$new_array[$field]['id'][] = $id;
$new_array[$field]['value'][] = $value;
}
}
//reset array keys back to sequential
$new_array = array_values($new_array);
Output of $new_array would be
Array
(
[0] => Array
(
[id] => Array
(
[0] => 10
)
[field] => new
[value] => Array
(
[0] => pqr
)
)
[1] => Array
(
[id] => Array
(
[0] => 14
[1] => 17
)
[field] => test
[value] => Array
(
[0] => abc
[1] => xyz
)
)
)
I'd like to filter an array which is created by converting XML to an array.
I'd like to remove all parent keys of arrays with key = 0 and an empty value (f.e. "InvalidKey"), but not the ones with a custom name and no value (f.e. "column").
I've already used array_filter (even in combination with array_map), but those functions will filter too few or too much information from the array.
I've also tried to create a loopable function to check if the current array has a key of 0 and an empty value, but I don't know how to get the parent key of the current array, f.e.:
Array
(
[InvalidKey] => Array
(
[0] => *NULL*
)
);
key($arrInput) = 0;
parent::key($arrInput) = "InvalidKey";
So, how to get from:
Array
(
[test] =>
[demo] => 524018
[column] =>
[xml] => Array
(
[Header] => Array
(
[0] => Array
(
[ValidKey] => Array
(
[0] => 1234
)
[InvalidKey] => Array
(
[0] =>
)
)
)
[Body] => Array
(
[0] => *NULL*
)
[Footer] => Array
(
[0] => Array
(
[ValidKey] => Array
(
[0] => I am valid
)
[MoreValidKey] => Array
(
[0] => I am valid too
)
[InvalidKey] => Array
(
[0] =>
)
)
)
)
)
To:
Array
(
[test] =>
[demo] => 524018
[column] =>
[xml] => Array
(
[Header] => Array
(
[0] => Array
(
[ValidKey] => Array
(
[0] => 1234
)
)
)
[Footer] => Array
(
[0] => Array
(
[ValidKey] => Array
(
[0] => I am valid
)
[MoreValidKey] => Array
(
[0] => I am valid too
)
)
)
)
)
PS: The used array key names are variable. For simplicity I used "(In)ValidKey". The array can be as much levels deep as possible, so I can't suffice with 2 for loops.
You need to write a custom script which checks all elements of your array.
Example:
<?php
$test = [
[
[
"asdf",
"",
0,
false,
true,
[
"asdf",
"",
[]
]
],
[]
],
[]
];
function removeEmptyElements(array $array)
{
foreach ($array as $key => $value) {
if (is_array($value))
$value = removeEmptyElements($value);
if (empty($value) && false !== $value && 0 !== $value)
unset($array[$key]);
else
$array[$key] = $value;
}
return $array;
}
print_r(removeEmptyElements($test));
Is there a way to delete a dimension in a array (only if it's empty), it's pretty dificult to explain with words, so that's what i want to do :
I have an array that returns :
(
[region1] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
)
I want it to be :
(
[region1] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
foreach($array as $key => $value) {
$array[$key] = reset($value);
}
That will replace each value in the outer array with the first element of that value.
i have a multidimensional array whose index/keys (not the values) are like this:
this is how the submitted array looks
[param] => Array
(
[3] => groupedlista
[0] => groupedlistb
[2] => groupedlistc
)
[f_name] => Array
(
[3] => grouplistaa
[0] => grouplistbb
[2] => grouplistcc
)
[f_label] => Array
(
[3] => grouplistL3
[0] => grouplistL0
[2] => grouplistL2
)
this is how the order looks
0,2,3
i want that Result
[param] => Array
(
[0] => groupedlistb
[1] => groupedlistc
[2] => groupedlista
)
[f_name] => Array
(
[0] => grouplistbb
[1] => grouplistcc
[2] => grouplistaa
)
[f_label] => Array
(
[0] => grouplistL0
[1] => grouplistL2
[2] => grouplistL3
)
that's it
PS: i use a jquery sort / add / delete feature in the form and i prefer to do the final sorting php-based. the index array [$i] is required to be declared at the form.
$order = '0,2,3';
$out = array(); // This will hold the sorted values
$order = explode(',',$order); // Turn the order into an array
foreach ($multiDimArray as $key => $subArray) { // Loop outer array
foreach ($order as $pos) { // Loop order array
if (isset($subArray[$pos])) { // Make sure the key exists
$out[$key][] = $subArray[$pos]; // Put the correct value in the correct place
}
}
}
print_r($out);
