How to explode ans change the array values into key? - php

I am having an array like this.
Array
(
[0] => Array
(
[0] => a~226
[1] => a~228
)
[1] => Array
(
[0] => b~123
[1] => b~209
)
[2] => Array
(
[0] => c~161
[1] => c~140
)
)
I want to explode this array using ~ symbol and i want value to be a key in php array.i want an array like this.Kindly help me write the code.
Array
(
[0] => Array
(
[a] => 226
[a] => 228
)
[1] => Array
(
[b] => 123
[b] => 209
)
[2] => Array
(
[c] => 161
[c] => 140
)
)
Thanks in advance...


You cannot have such an array.
The keys must be unique (Like Mark Baker say).
You can have something like this:
Array
(
[a] => Array
(
[0] => 226
[1] => 228
)
[b] => Array
(
[0] => 123
[1] => 209
)
[c] => Array
(
[0] => 161
[1] => 140
)
)
The code to do this:
$array = array(
array("a~226", "a~228"),
array("b~123", "b~209"),
array("c~161", "c~140")
);
$result = array();
foreach($array as $inner_array) {
foreach($inner_array as $value) {
$spitted = explode("~", $value);
$result[$spitted[0]][] = end($spitted);
}
}
An working example: http://codepad.viper-7.com/znhhqB


try this
$arr_new = array();
foreach($arr_main as $key=>$arr)
{
foreach($arr as $k=>$val)
{
$str = explode("~",$val);
$arr_new[$key][$str[0].$k]=$str[1];
}
}
will maintain the index as a0, a1

How do i make one array out of two arrays containing different values

I have two arrays, one called fetched_services and one called fetched_companies, they look like this:
fetched_services
(
[1] => Array
(
[id] => 11
[child_services] => Array
(
[0] => Array
(
[id] => 153
)
[1] => Array
(
[id] => 137
)
[2] => Array
(
[id] => 138
)
)
)
)
fetched_companies
(
[0] => stdClass Object
(
[services] => Array
(
[0] => 25
[1] => 102
)
)
)
What i want to achieve is to end up with an array like fetched_services but only having child_services with id of fetched_companies["services"].
What i have tried is this:
$services = [];
$isFound = false;
foreach ($fetched_services as $fetched_service) {
foreach ($fetched_service["child_services"] as $fetched_child_service) {
$fetched_service["child_services"] = [];
foreach ($fetched_companies as $fetched_company) {
if( (in_array($fetched_child_service["id"],$fetched_company->services)) ) {
$fetched_service["child_services"][] = $fetched_child_service;
$isFound = true;
}
}
if($isFound) {
$services[] = $fetched_service;
$isFound = false;
}
}
}
This outputs this:
Array
(
[0] => Array
(
[id] => 11
[child_services] => Array
(
[0] => Array
(
[id] => 116
)
)
)
[1] => Array
(
[id] => 11
[child_services] => Array
(
[0] => Array
(
[id] => 117
)
)
)
)
As you can see the resulting array have two arrays containing same id but the child_services are different.
What i want to end up with is this:
Array
(
[0] => Array
(
[id] => 11
[child_services] => Array
(
[0] => Array
(
[id] => 116
)
)
(
[0] => Array
(
[id] => 117
)
)
)
)
What am i doing wrong here? Thanks!

Your question is a bit unclear (I'll edit/delete this if/when you clarify, see my comment above), but you could probably make use of array_filter by only keeping services that are present in said list (via in_array):
$result = array_filter(
$fetched_services['child_services'],
fn(array $child_service): bool => in_array($child_service['id'], $fetched_companies[0]->services, true)
);

Collecting values from a multidimensional array using foreach loops

There is an array which is built looks like the following (with some more values which i left away for this example):
Array
(
[0] => Array
(
[id] => 44
[cars] => Array
(
[0] => Array
(
[id] => 38
)
[1] Array
(
[id] => 39
)
)
)
[1] => Array
(
[id] => 45
[cars] => Array
(
[0] => Array
(
[id] =>136
)
[1] =>Array
(
[id] =>137
)
[2] =>Array
(
[id] =>138
)
)
)
)
I want to build another array from the above in the following form:
Array
(
[0] => Array
(
['car_filter_sort_id'] => 44
['car_id'] => 38
)
[1] => Array
(
['car_filter_sort_id'] => 44
['car_id'] => 39
)
[2] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 136
)
[3] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 137
)
[4] => Array
(
['car_filter_sort_id'] => 45
['car_id'] => 138
)
)
I tried to achieve this with following function:
foreach($filterSortSaveArray as $filterSortSaveArray['cars'] => $value){
$id = $filterSortSaveArray['id'];
foreach($value['cars'] as $value => $car){
$field_values['car_filter_sort_id'] = $id;
$field_values['car_id'] = $car['id'];
}
}
But the the result differs from what I have expected. Any suggestions?

There are two big issues in your code. First, are you referencing undefined value with $filterSortSaveArray['cars'], since there is no 'cars' key in the first level of the original array. Second, by assigning values to $field_values['car_filter_sort_id'] and $field_values['car_id'] in the loop you are just overriding them in each iteration. You need to push the values into an array using []= operator (which is equivalent to applying array_push()).
Try this:
$result = [];
foreach($filterSortSaveArray as $k => $v) {
if (!is_array($v['cars']))
continue;
$id = $v['id'];
foreach ($v['cars'] as $i => $car){
$result[] = [
'car_filter_sort_id' => $id,
'car_id' => $car['id']
];
}
}

how to find difference in single dimensional array with single dimensional array in php

I have two array two array. First is multidimensional and other is single dimensional. I want to find difference between them. How do I found.
$arrayresult
Array 1
Array (
[0] => Array ( [0] => ishani.lad [1] => 9033187384 )
[1] => Array ( [0] => rajkumar.prajapati [1] => 8460078459 )
[2] => Array ( [0] => lokesh.bhandari [1] => 9687060900 )
[3] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[4] => Array ( [0] => vishal.dake [1] => 9879815299 )
[5] => Array ( [0] => mohsin [1] => 8347163123 )
)
$useduser
Array 2
Array (
[0] => ishani.lad
[1] => rajkumar.prajapati
[2] => lokesh.bhandari
)
I need difference as result as below
Result
Array (
[0] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[1] => Array ( [0] => vishal.dake [1] => 9879815299 )
[2] => Array ( [0] => mohsin [1] => 8347163123 )
)
I have used solution as
$resultremainig = [];
foreach($arrayresult as $val2){
if(!in_array($val2[0], $useduser)){
echo $val2[0]."<br>";
$resultremainig[] = $val2;
}
}
But it show last record also. Result of above code is as below. It always show me last record in second array's also
Array (
[0] => Array ( [0] => lokesh.bhandari [1] => 9687060900 )
[1] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[2] => Array ( [0] => vishal.dake [1] => 9879815299 )
[3] => Array ( [0] => mohsin [1] => 8347163123 )
)

If you wanted you could try using nested loops like so:
<?php
$arrOne = $arrFinal = [
["ishani.lad", 9033187384],
["rajkumar.prajapati", 8460078459],
["lokesh.bhandari" , 9687060900],
["shishanshu.rai" , 8401915337],
["vishal.dake" , 9879815299],
["mohsin" , 8347163123],
];
$arrTwo = [
"ishani.lad",
"rajkumar.prajapati",
"lokesh.bhandari",
];
foreach($arrOne as $key=>$item){
foreach($arrTwo as $k=>$v){
if(in_array($v, $item)){
unset($arrFinal[$key]);
}
}
}
var_dump($arrFinal);
// PRODUCES:::
array (size=3)
3 =>
array (size=2)
0 => string 'shishanshu.rai' (length=14)
1 => int 8401915337
4 =>
array (size=2)
0 => string 'vishal.dake' (length=11)
1 => int 9879815299
5 =>
array (size=2)
0 => string 'mohsin' (length=6)
1 => int 8347163123

You could use array_filter():
$output = array_filter($arrayresult, function($a) use ($useduser) {
return !in_array($a[0], $useduser);
});

Hi You can also try this
$one = array(array('ishani.lad',9033187384),array('rajkumar.prajapati',8460078459),array('lokesh.bhandari',9687060900),array('shishanshu.rai',8401915337),array('vishal.dake',9879815299),array('mohsin',8347163123));
$two = array('ishani.lad','rajkumar.prajapati','lokesh.bhandari');
foreach($one as $array){
if(!in_array($array[0],$two)){
$final[] = $array;
}
}
echo "<pre>";print_r($final);
Output
Array
(
[0] => Array
(
[0] => shishanshu.rai
[1] => 8401915337
)
[1] => Array
(
[0] => vishal.dake
[1] => 9879815299
)
[2] => Array
(
[0] => mohsin
[1] => 8347163123
)
)

Trim the value before checking in $useduser array
$resultremainig = [];
foreach($arrayresult as $val2){
// this removes any extra spaces from the search string
if(!in_array(trim($val2[0]), $useduser)){
echo $val2[0]."<br>";
$resultremainig[] = $val2;
}

You need to use the array_diff function.
Store your 2 arrays in variables and compare them.

Create a multidimensional array in PHP by separating each line based off a specific value

This is the array I have:
Array
(
[0] => name:string:255
[1] => weight:integer
[2] => description:string:255
[3] => age:integer
)
I want it to look like this
NewArray
(
[0] => Array
(
[0] => name
[1] => string
[2] => 255
[1] => Array
(
[0] => weight
[1] => integer
[2] => Array
(
[0] => description
[1] => string
[2] => 255
[3] => Array
(
[0] => age
[1] => integer
)
Or better yet, I would prefer this result. Making two separate arrays based off the number of groups.
NewArray1
(
[0] => Array
(
[0] => name
[1] => string
[2] => 255
[1] => Array
(
[0] => description
[1] => string
[2] => 255
)
NewArray2
(
[0] => Array
(
[0] => weight
[1] => integer
[1] => Array
(
[0] => age
[1] => integer
)
I have tried exploding and implode and foreaching but I'm not quite getting the result I want.

Use array_reduce() to build a new array while iterating over the old, splitting it up by type:
$array = [
'name:string:255',
'weight:integer',
'description:string:255',
'age:integer',
];
$result = array_reduce($array, function(&$result, $item) {
$parts = explode(':', $item, 3);
$result[$parts[1]][] = $parts;
return $result;
}, []);

Try this:
<?php
$array = array("name:string:255", "weight:integer", "description:string:255", "age:integer");
function map_func($value) {
return explode(':', $value);
}
$newArray = array_map(map_func, $array);
echo "Output 1:\n";
print_r($newArray);
$sorted = array();
foreach($newArray as $el)
$sorted[$el[1]][] = $el;
echo "Output 2:\n";
print_r($sorted);
Output:
Output 1:
Array
(
[0] => Array
(
[0] => name
[1] => string
[2] => 255
)
[1] => Array
(
[0] => weight
[1] => integer
)
[2] => Array
(
[0] => description
[1] => string
[2] => 255
)
[3] => Array
(
[0] => age
[1] => integer
)
)
Output 2:
Array
(
[string] => Array
(
[0] => Array
(
[0] => name
[1] => string
[2] => 255
)
[1] => Array
(
[0] => description
[1] => string
[2] => 255
)
)
[integer] => Array
(
[0] => Array
(
[0] => weight
[1] => integer
)
[1] => Array
(
[0] => age
[1] => integer
)
)
)

I doubt the following is the best solution but it does return what you wanted.
$array = array(
"0" => "name:string:255",
"1" => "weight:integer",
"2" => "description:string:255",
"3" => "age:integer"
);
foreach ($array as $key => $val) {
foreach (explode(':', $val) as $part) {
$new_array[$key][] = $part;
}
}
print_r($new_array);
above returns the following.
Array
(
[0] => Array
(
[0] => name
[1] => string
[2] => 255
)
[1] => Array
(
[0] => weight
[1] => integer
)
[2] => Array
(
[0] => description
[1] => string
[2] => 255
)
[3] => Array
(
[0] => age
[1] => integer
)
)

So you have a 1-dimentional array of strings ($arr01) . strings are separated by :
and you need to have a 2-dimentional array ($arr02) where the second dimension is an array of strings composed by splitting the initial set of strings based on their separator character :
$arr01 = array("name:string:255", "weight:integer", "description:string:255", "age:integer");
$arr02 = array(array());
for($i=0; $i<sizeof($arr01); $i++) {
$arr02[$i] = explode(":",$arr01[$i]);
}
display the two arrays....
echo "array 01: <br>";
for($i=0; $i<sizeof($arr01); $i++) {
echo "[".$i."] ".$arr01[$i]."<br>";
}
echo "<br><br>";
echo "array 02: <br>";
for($i=0; $i<sizeof($arr01); $i++) {
echo "[".$i."] ==> <br>";
for($j=0; $j<sizeof($arr02[$i]); $j++) {
echo " [".$j."] ".$arr02[$i][$j]." <br>";
}
}
echo "<br><br>";

php unique multidimensional array by keeping entry with the highes value from one dimension?

I have another array unique question in the endless list of questions about them.
I can imagine this problem is quite simple to solve but I simply do not come on it.
Just because there are so many questions on this subject i wasn't able to find anything useful in this case.
the array:
Array
(
[0] => Array
(
[0] => blabla values
[1] => 91.181818181818
)
[1] => Array
(
[0] => blabla same values
[1] => 95.333333333333
)
[2] => Array
(
[0] => blabla other values
[1] => 86
)
[3] => Array
(
[0] => blabla other values
[1] => 92.5
)
[4] => Array
(
[0] => blabla same values
[1] => 88.5
)
)
I want to unique the array by the first array dimension and only keep the entry with the highest value from the second.
Maybe in MYSQL this would be no big deal but at the moment i am not able to implement something like that in php.
desired output array would be:
Array
(
[0] => Array
(
[0] => blabla values
[1] => 91.181818181818
)
[1] => Array
(
[0] => blabla same values
[1] => 95.333333333333
)
[2] => Array
(
[0] => blabla other values
[1] => 92.5
)
)
Has anyone a clever idea?

<?php
$list = array(
array('blabla values',91.181818181818),
array('blabla same values', 95.333333333333),
array('blabla other values', 86),
array('blabla other values', 92),
array('blabla same values', 88.5),
);
$result = array();
foreach ($list as $item)
{
$key = $item[0];
$value = $item[1];
if (!isset($result[$key]) || $result[$key][1] < $value)
{
$result[$key] = $item;
}
}
$result = array_values($result);
print_r($result);
the output:
Array
(
[0] => Array
(
[0] => blabla values
[1] => 91.1818181818
)
[1] => Array
(
[0] => blabla same values
[1] => 95.3333333333
)
[2] => Array
(
[0] => blabla other values
[1] => 92
)
)

usort($arr, function ($a, $b){
return $a[1] - $b[1];
});
$out = array();
foreach ($arr as $key => $value){
$out[$value[0]] = $value[1];
}
$arr = array_map(NULL, array_keys($out), $out);
Output:
Array
(
[0] => Array
(
[0] => blabla same values
[1] => 95.333333333333
)
[1] => Array
(
[0] => blabla other values
[1] => 86
)
[2] => Array
(
[0] => blabla values
[1] => 91.181818181818
)
)
