PHP - Php Unserialize Adding Brackets Around Array Keys?

Is it possible to create a PHP array that contains only keys?

	array
	1
	3
	5
	6
	7
	

 

I have a query that returns row ID's that I want to put into an array to do some work.  There is no real concept of a "value" - I just need to store a list of the database table rows that i want and that's it!

Hello

I am having some trouble with array_keys

I have an array for which I want to return all the keys based on value X

This is my code:

Code: [Select]

$depth = array_keys(X', $Array);

echo print_r ($depth,1);



I have checked the content of my array $Array and it contains at least 1 instance of 'X' but I am getting nothing when I do the print_r

Any suggestions would be appreciated

Thanks

Hi ..
i have an array format like (mysql result array)
$new_array=Array ( [0] => Array ( [quantity] => 5 )  [1] => Array ( [quantity] => 25 )  [2] => Array ( [quantity] => 20 ) )

I have to convert this array into the following format
$new_array['quantity'][0]=5
$new_array['quantity'][1]=25
$new_array['quantity'][2]=20


How to convert this array format using any standard array method.

is there a way to reset the array keys? to 0,1,2,3,...

also for example that i have something like this:

$array['dog']='dog';
$array['mouse']='mouse';
$array['cat']='cat';

and i want it like this:

$array[0]='dog';
$array[1]='mouse';
$array[2]='cat';

is there a function for that already in php?

I have an array of type
Code: [Select]
Array ( [2] => Array ( [name] => Shelby Baptist Medical Ctr [city] => Alabaster ) [1] => Array ( [name] => Andalusia Regional Hospital [city] => Andalusia ) [0] => Array ( [name] => Long Term Hospital of Anniston [city] => Anniston ))
How can sort the keys of an array but there content remains the same so that they are like
Code: [Select]
Array ( [0] => Array ( [name] => Shelby Baptist Medical Ctr [city] => Alabaster ) [1] => Array ( [name] => Andalusia Regional Hospital [city] => Andalusia ) [2] => Array ( [name] => Long Term Hospital of Anniston [city] => Anniston ))
Can someone please point me if there is any func. for this

hey guys im trying to result an array key and value if it has one...the code and results are below if anyone can help with this simple problem...thanks alot

Code: [Select]
<?php

$columns = array('news_id' => 'id', 'news');

foreach ($columns as $column => $column_alias)
{
echo $column . ' ' . $column_alias;
}
?>
the result im getting is:

news_id  id
0 news

but im just after the result of just result the column name and alias (if it has one)
so im looking for the result

news_id  id
news

The title makes it sound more complicated than it is.

I have a recurring function that searches for a specific value in a multi-dimensional array. When it finds it, it returns an array of the index.

For example, if it found the value at $array[1][4][2][0], it would return an array like this:
[0]=>1
[1]=>4
[2]=>2
[3]=>0

Here's the function.
Code: [Select]
<?php

// Other Code

/**
 * Find's the parent of an item
 * Unfortunately, it takes a bit more work than just using the loudspeaker at a grocery store
 * @param int $parent The parent to be searched for
 * @param array $array 
 * @param array $cur_index
 */
private function findParent($parent, $array, $cur_index)
{
    for($i = 0; $i < count($array); $i++) { // Search the array
        if($array[$i]['id'] == $parent) { // If the parent is found
            $cur_index[count($cur_index)] = $i;
            return array(true, $cur_index);
        }

        if(count($array[$i][1]) > 1) { // Call findParent again to search the child
            $cur_index[count($cur_index)] = $i;
            $found_in_child = $this->findParent($parent, $array[$i], $cur_index);
            if($found_in_child[0]) {
                return $found_in_child;
            }
        }
    }
    
    return array(false); // Return no matches
}
I need to be able to call that index using the keys from the key array (as we will call it). How can I do that?

Thank you in advance for your help.

I have a sequential multidimensional array with many outer rows where all the inner arrays have the same number of elements as another sequential array which represents metadata of the first array's inner arrrays.

$keys: 

["time","system1_typeA","system2_typeA","system1_typeB","system3_typeC","system2_typeB","system1_typeC"]

$arrayValues: 

[
    ["2020-06-27 07:40:06",2.16,9.25,9.44,7.76,5.43,1.12],
    ["2020-06-27 07:40:23",2.66,8.93,4.31,6.59,8.44,3.42],
    ["2020-06-27 07:41:24",8.71,2.78,8.92,6.58,3.65,4.38],
    ["2020-06-27 07:41:58",1.86,6.36,2.65,3.99,7.25,3.32],
    ["2020-06-27 07:42:33",8.71,3.66,8.82,8.54,8.22,4.51]
]

My desired output is: 

{
    "time": ["2020-06-27 07:40:06", "2020-06-27 07:40:23", "2020-06-27 07:41:24", "2020-06-27 07:41:58", "2020-06-27 07:42:33"],
    "system1": {
        "typeA": [2.16, 2.66, 8.71, 1.86, 8.71],
        "typeB": [9.44, 4.31, 8.92, 2.65, 8.82],
        "typeC": [1.12, 3.42, 4.38, 3.32, 4.51]
    },
    "system2": {
        "typeA": [9.25, 8.93, 2.78, 6.36, 3.66],
        "typeB": [5.43, 8.44, 3.65, 7.25, 8.22]
    },
    "system3": {
        "typeC": [7.76, 6.59, 6.58, 3.99, 8.54]
    }
}

Is there much faster way to do so than the following?  I would like to use a built in function like array_combine() if possible, but grouping by system and type creates an issue.

function transform(array $keys, array $arrayValues):array {
    $map=[];
    foreach ($keys as $key) {
        $map[] = explode('_',$key);
    }
    $count=count($keys);

    $newValues=[];
    foreach ($arrayValues as $i=>$arrayValue) {
        $newValues['time'][]=$arrayValue[0];
        for ($i = 1; $i < $count; $i++) {
            $newValues[$map[$i][0]][$map[$i][1]][]=$arrayValue[$i];
        }
    }
    return $newValues;
}

 

Hey guys so I've been trying to figure something out for a day now but I really don't know where to start, basically I'm trying to create some kind of function that goes through my array and checks if the keys value is less than 5, if it is then I want to unset the key removing it from the array,   I programmed this underneath as this is basically what I want to achieve however there's a syntax issue as the array_key_excists function doesn't seem to allow the if statement, if anyone knows anything about it it would be very helpful!

if (array_key_exists(($key > 5),$data))
 {
    unset($data[$key]);
 }

any help is very much appreciated,   Thanks very much in advance!

Hi, I'm not sure if this is a wierd one, I have lots of arrays i'm looping through like this to see them:-


for($i=0; $i <count($confirmed); $i++){//loop through
     print_r_html($confirmed[$i]);
}


Which shows the following :-

Code: [Select]
Array
(
    [0] => AAAAAA-BBBBBB
    [1] => 2
    [2] => 2010-09-29
)
Array
(
    [0] => AAAAAA-BBBBBB
    [1] => 2
    [2] => 2010-09-28
)
Array
(
    [0] => CCCCCC-DDDDDD-EEEEEE
    [1] => 3
    [2] => 2010-09-29
)
Key 0 is a Groupconcat split by "-"
Key 1 shows how many fields are in 0
Key 2 is just the date

What I would like to do is split the first array into 2 arrays, the second in 2, and the third into 3 (therefore ungrouping the groupconcat if you will)
as such:-

Code: [Select]
First into these two:-
Array
(
    [0] => AAAAAA
    [1] => 2
    [2] => 2010-09-29
)
Array
(
    [0] => BBBBBB
    [1] => 2
    [2] => 2010-09-29
)
Second into these two:-
Array
(
    [0] => AAAAAA
    [1] => 2
    [2] => 2010-09-28
)
Array
(
    [0] => BBBBBB
    [1] => 2
    [2] => 2010-09-28
)
Third into these two:-
Array
(
    [0] => CCCCCC
    [1] => 3
    [2] => 2010-09-29
)
Array
(
    [0] => DDDDDD
    [1] => 3
    [2] => 2010-09-29
)
Array
(
    [0] => EEEEEE
    [1] => 3
    [2] => 2010-09-29
)
)
I know I can get out the info from the first of the keys in each array by putting this into the loop:-


for($i=0; $i <count($confirmed); $i++){//loop through
     if($i==0){
             $seperated[] = explode("-",$confirmed[$i]);//split by "-"
     } 
}
    print_r_html($seperated);



but i'm not sure how to copy the other keys at the same time? If anyone has got any ideas that would be great!
thanks in advance
Kev.

Say i have two arrays with custom keys. What would be the easiest way to write a function that would determine if all the keys in arrayOne are in arrayTwo? The example below would return false because keys 3 and 4 are missing in arrayTwo. Any help would be much appreciate. thanks!

Code: [Select]
<?php

$arrayOne['1'] = "adg";
$arrayOne['2'] = "a4g";
$arrayOne['3'] = "346";
$arrayOne['4'] = "etwe";

$arrayTwo['1'] = "xcb";
$arrayTwo['2'] = "acbr";
$arrayTwo['6'] = "yiy";
$arrayTwo['7'] = "mmm";
?>

Hi,

I have the following code that takes a list from a mySQL db and puts it into an array that shows 'gig date, venue, city' per entry: -

 
Code: [Select]
while ($row = mysql_fetch_array($result,MYSQL_ASSOC))
{

$array[] = ($row['date'].', '.$row['gl_venue'].', '.$row['gl_city']);
}

$output = json_encode($array);
this outputs JSON like so:
Code: [Select]
["06-05-2011, O'neills, Southend","07-05-2011, Power League, Peterborough","14-05-2011, Queen Victoria hall, Oundle",.......]
how do I add keys into the array so I get something like:
Code: [Select]

{"gigs":[
 { "gig": "date, venue, city",}
]}
 
at least I think so anyway!?!

What I want to do is eventually be able to parse a JSON listing into Objective-C and be able to call key/pairs into various different parts of an app.

I'm pretty new to this so any advice would be great.

Code: [Select]
array ( 0 => array ( 'id' => '6', 't' => 'Food & Beverage', ), 1 => array ( 'id' => '6', 't' => 'Food & Beverage', ), 2 => array ( 'id' => '2', 't' => 'Automotive', ), )
how to sum it, to get:

Code: [Select]
array ( 0 => array ( 'id' => '6', 't' => 'Food & Beverage', 'cnt' => '2' ), 1 => array ( 'id' => '2', 't' => 'Automotive', 'cnt' => '1' ), )

Hi guys,

I am getting data from a json source:

```

$jsondata = file_get_contents($url);
  $response = json_decode($jsondata, true)
  echo "<pre>"; print_r(array_keys($response));; echo "</pre>";

```

and this returns:

```

Array
(
    [0] => jsonapi
    [1] => data
    [2] => links
)

```

I want  to extract data from specific key in the data array (eg 'title'):

```

    [data] => Array
        (
            [0] => Array
                (
                    [type] => recipes
                    [id] => d6cd7643-6e44-4d26-9ed9-9da7196cef12
                    [attributes] => Array
                        (
                            [internalId] => 7
                            [isPublished] => 1
                            [title] => Deep mediterranean quiche
                            [createdAt] => 2019-05-07T13:34:27+0200
                            [updatedAt] => 2019-05-07T13:34:27+0200
                            [isPromoted] => 1
                            [path] => /recipes/deep-mediterranean-quiche
                            [cookingTime] => 30
                            [difficulty] => medium
                            [ingredients] => Array
                                (
                                    [0] => For the pastry:
                                    [1] => 280g plain flour
                                    [2] => 140g butter
                                    [3] => Cold water
                                    [4] => For the filling:
                                    [5] => 1 onion
                                    [6] => 2 garlic cloves
                                    [7] => Half a courgette
                                    [8] => 450ml soya milk
                                    [9] => 500g grated parmesan
                                    [10] => 2 eggs
                                    [11] => 200g sun dried tomatoes
                                    [12] => 100g feta
                                )

                            [numberOfservings] => 8
                            [preparationTime] => 40
                            [instructions] => 

```

How do I loop through the data array and select just the 'title' and 'difficulty' for example?
