How can i make the values of such an array unique.
Array ( [0] => Array ( [0] => wallet [1] => pen [2] => perfume [3] => pen) )
as there is pen twice i would like it to be deleted in this way :
( [0] => Array ( [0] => wallet [1] => pen [2] => perfume) )
OR
( [0] => Array ( [0] => wallet [1] => perfume [2] => pen) )
and i would like it to apply for any length.
thanks for your help
How about array_flip used twice:
$arr = Array(0 => wallet, 1 => pen, 2 => perfume, 3 => pen);
$arr = array_flip(array_flip($arr));
print_r($arr);
output:
Array
(
[0] => wallet
[3] => pen
[2] => perfume
)
If you want to renumbered the indexes, add this ligne after:
$arr = array_values($arr);
if you just want to select a unique value you need to pass the array that you want to compare the values, I am assuming you passed the main array, you need to pass the array where the problem is found which is in your case the index 0 of an array
$result = array_unique($input[0]);
$input will have an array of unique values so pen will not be 2
if you need to delete any duplicated values in the array you can do this.
$input[0] = array_unique($input[0]);
if you need to reset the index you can use this
$new_index = array_values($input[0]);
print_r($new_index);
$tmp = array ();
foreach ($array as $row)
array_push($tmp,array_unique($row));
Here is the solution for multi dimensopnal array
$res = array();
foreach($your_array as $key=>$val){
$res[$key] = array_unique($val);
}
echo "<pre>";
print_r($res);

Is it possible to change the highlighted word to numbers without changing it in database table?
wanted from this
$value['how']
to this
$value['0']
Yes, you need to use array_values()
$array = array("how" => "how-value", "to" => "to-value");
print_r(array_values($array));
Output:
Array
(
[0] => how-value
[1] => to-value
)
EDIT BY OP
To get the value
foreach($array as $key => $value) {
$someArray = array_values($value);
print_r($someArray[0]);
}
//return 144
#Milan Chheda answer is correct but I am just briefing here so the user can get a better idea of that.
Use array_values() to get the values of an array.
$FormedArray = array_values($your_array);
now print that array print_r($FormedArray);
You will get your result like
Array
(
[0] => 144
[1] => 41
[2] => USA
[3] => 12
[4] => 12
)
Here is a working example. https://eval.in/843720
I have the following array:
Array
(
[0] => Array
(
[ContractorName] => Joe Soap
[BonusAmount] => 73.92
)
[1] => Array
(
[ContractorName] => Mike Michaels
[BonusAmount] => 68.55
)
[2] => Array
(
[ContractorName] => John Smith
[BonusAmount] => 34.35
)
[3] => Array
(
[ContractorName] => Pete Peterson
[BonusAmount] => 24.61
)
[4] => Array
(
[ContractorName] => Pete Smith
[BonusAmount] => 22.76
)
)
How do I go about ending up with an array that looks like this:
Array
(
[Joe Soap] => 73.92
[Mike Michaels] => 68.55
[John Smith] => 34.35
[Pete Peterson] => 24.61
[Pete Smith] => 22.76
)
I'm a bit lost at the moment. I have tried creating a new array by looping over the first array, but I'm getting unwanted results. Any help greatly appreciated.
Use array_combine with array_column as
array_combine(array_column($records, 'ContractorName'),array_column($records, 'BonusAmount'));
Go through entire array using foreach and then use each piece to construct new array.
$out = [];
foreach ($inputArray as $v) {
$out[$v['ContractorName']] = $v['BonusAmount'];
}
Second solution is by using array_combine and array_column.
$keys = array_column($inputArray, 'ContractorName');
$values = array_column($inputArray, 'BonusAmount');
$output = array_combine($keys, $values);
//Or put everything in single line
$output = array_combine(array_column($inputArray, 'ContractorName'), array_column($inputArray, 'BonusAmount'));
Third option
$output = array_column($inputArray, 'BonusAmount', 'ContractorName');
You can use one array_column(), and with the third parameter to specify the index. Live Demo.
array_column($array, 'BonusAmount', 'ContractorName');
I am creating a set of arrays with the following loop:
$assessmentArr = explode("&", $assessmentData);
foreach($assessmentArr as $data) {
$fullArr = explode("_", $data);
// Break down to only archetype and value
$resultArr = explode("=", $fullArr[2]);
//print_r($resultArr);
}
Which produces the following results:
Array
(
[0] => community-support
[1] => 24
)
Array
(
[0] => money-rewards
[1] => 30
)
Array
(
[0] => status-stability
[1] => 15
)
Array
(
[0] => personal-professional-development
[1] => 32
)
Array
(
[0] => community-support
[1] => 9
)
Array
(
[0] => money-rewards
[1] => 12
)
Array
(
[0] => status-stability
[1] => 16
)
Array
(
[0] => personal-professional-development
[1] => 29
)
I need to combine these into one array, and where the [0] value matches, I need to add the [1] value together.
So I would like the final output to be something like:
Array
(
[community-support] => 33
[money-rewards] => 42
[status-stability] => 31
[personal-professional-development] => 61
)
I found this question: How to merge two arrays by summing the merged values which will assist me in merging and adding the values together, but I'm not sure how to go about it when the arrays aren't assigned to a variable. Is what I am trying to do possible or am I going about this the wrong way?
Don't make it complicated, just check if the results array already has an element with that key and if not initialize it otherwise add it. E.g.
(Add this code in your loop):
if(!isset($result[$resultArr[0]]))
$result[$resultArr[0]] = $resultArr[1];
else
$result[$resultArr[0]] += $resultArr[1];
Then you have your desired array:
print_r($result);
You could do it like this
$assessmentArr = explode("&", $assessmentData);
$finalArr = array();
foreach($assessmentArr as $data) {
$fullArr = explode("_", $data);
// Break down to only archetype and value
$resultArr = explode("=", $fullArr[2]);
if(array_key_exists($resultArr[1], $finalArr)){
$finalArr[$resultArr[0]] += $resultArr[1];
}else{
$finalArr[$resultArr[0]] = $resultArr[1];
}
}
First check, if the key already exists in the array, if so you add the value to the value in the final array. Otherwise you add the new index to the final array, with the value from resultArr as inital value.
... way too slow :/
here is my code
array 1:
Array
(
[0] => Array
(
[id] => 42166
[Company_Website] => http://www.amphenol-highspeed.com/
[company_name] => Amphenol High Speed Interconnect
[city_name] => New York
[country_name] => USA
[comp_img] =>
)
)
array 2:
Array
(
[0] => Array
(
[Product_Name] => CX to CX,Amphenol High Speed Active,Serial Attached SCSI
[company_id] => 42166
)
)
php code:
$total = count($result);
$i=0;
foreach ($result as $key=>$value) {
$i++;
$company_id= implode(",",(array)$value['id']);
if ($i != $total)
echo',';
}
code to fetch array 2:
foreach ($res as $key1=>$value1) {
echo $total;
$event[$value['company_name']] = $value1['Product_Name'];
if($value1['company_id']==$company_id )
{
echo " match";
//$key[['company_name']]= $value1['Product_Name'];
}
else
{
echo "not matched";
}
}
what i need create a new index if company_id is match with id of another array.
that is product_name.
if product name is there just create index otherwise show null.
i want show in key=> value .
output should be like:
Array
(
[0] => Array
(
[id] => 42166
[Company_Website] => http://www.amphenol-highspeed.com/
[company_name] => Amphenol High Speed Interconnect
[city_name] => New York
[country_name] => USA
[comp_img] =>
[Product_Name] => CX to CX,Amphenol High Speed Active,Serial Attached SCSI
)
)
Your all problems with keys in arrays will disappear when you will start using company ids as a keys.
To reindex you arrays, you can use:
$array1 = array_combine(array_column($array1, 'id'), $array1);
$array2 = array_combine(array_column($array2, 'company_id'), $array2);
In the output you will get:
array 1:
Array
(
[42166] => Array
(
[id] => 42166
...
)
)
And array 2 will looks similiar - id as a key.
So accessing to the elements using ids as a keys is a piece of cake right now.
I have an multidimensional array:
Array
(
[0] => Array
(
[Id] => 1
[MTime_Id] => 1
[MName] => Breakfast
[DName] => Other Cereals
[IName] =>
[Date] => 2013-02-05
)
[1] => Array
(
[Id] => 1
[MTime_Id] => 1
[MName] => Breakfast
[DName] => Porridge
[IName] => Oats,Milk,Sugar
[Date] => 2013-02-06
)
[2] => Array
(
[Id] => 1
[MTime_Id] => 1
[MName] => Breakfast
[DName] => Porridge
[IName] => Oats,Milk,Sugar,Oats,Milk,Sugar
[Date] => 2013-02-05
)
)
And I am trying to use array unique to filter this
[IName] => Oats,Milk,Sugar,Oats,Milk,Sugar
I am having no luck. How can I filter the duplicates?
Cheers.
If you filter input and therefore don't have extra spaces in IName field, you can use something as simple as this for filtering:
$array[2]['IName'] = implode(',', array_unique(explode(',', $array[2]['IName'])));
The problem is that you habe in array two Oats,Milk,Sugar as element of IName, in array three you have Oats,Milk,Sugar,Oats,Milk,Sugar. This is not the same!
"Oats,Milk,Sugar"=="Oats,Milk,Sugar,Oats,Milk,Sugar" (or "Oats,Milk,Sugar".equals("Oats,Milk,Sugar,Oats,Milk,Sugar")) is false.
If you want to have it unique you have to explode the single results and then do a unique on it or you have to store the single values in seperate fields...
BTW: Here is a link how to remove duplicates from a multi dimensional array How to remove duplicate values from a multi-dimensional array in PHP
I am not sure if a function exists for that, here is a simple solution,
you can loop the array, and get the result of each value, then explode result, and insert it into an array.
then use the array_unique function.
try this:
$result = array();
foreach($arrays as $array)
{
$tmp = $array['IName'];
$tmp2 = explode(',',$tmp);
foreach ($tmp2 as $t)
{
$result[]=$t;
}
}
$array_unique = array_unique($result);
