Array format php - php

I need to change the format of an array returned in CodeIgniter, leaving a field of the database as index, I made the same querys in PHP and CodeIgniter and both are different, any suggestions? I am using result_array () in CodeIgniter and also result ();
I need this:
Array
(
[1_1] => Array
(
[0] => 1_1
[1] => 16
[2] => ch
[3] => Chemistry
)
[1_2] => Array
(
[0] => 1_2
[1] => 17
[2] => ch
[3] => Chemistry
)
[2_3] => Array
(
[0] => 2_3
[1] => 18
[2] => ch
[3] => Chemistry
)
[2_5] => Array
(
[0] => 2_5
[1] => 19
[2] => ch
[3] => Chemistry
)
[9_1] => Array
(
[0] => 9_1
[1] => 20
[2] => ch
[3] => Chemistry
)
)
Query results:
Array
(
[0] => Array
(
[pos] => 1_1
[tbl_id] => 16
[sub_id] => ch
[sub_name] => Chemistry
)
[1] => Array
(
[pos] => 1_2
[tbl_id] => 17
[sub_id] => ch
[sub_name] => Chemistry
)
[2] => Array
(
[pos] => 2_3
[tbl_id] => 18
[sub_id] => ch
[sub_name] => Chemistry
)
[3] => Array
(
[pos] => 2_5
[tbl_id] => 19
[sub_id] => ch
[sub_name] => Chemistry
)
[4] => Array
(
[pos] => 9_1
[tbl_id] => 20
[sub_id] => ch
[sub_name] => Chemistry
)
)
How can I delete the array that is at the beginning? Thank you.


$array = [
[
'pos' => '1_1',
'tbl_id' => 16,
'sub_id' => 'ch',
'sub_name' => 'Chemistry'
]
];
$result = [];
foreach ($array as $data) {
$values = array_values($data);
$result[$data['pos']] = $values;
}
This will give you what you want.
Array
(
[1_1] => Array
(
[0] => 1_1
[1] => 16
[2] => ch
[3] => Chemistry
)
)

I have a function that groups the last value in an array into a range of numbers, however it doesn't work with the above array. I have tried a number of different arrays with no success. The above array is generated by a mysql query result.
$getlocations = $db->query("
SELECT barcode
, test_num
, magnum
, sect
, slidenum
FROM fas_log
WHERE barcode LIKE '%$bcinv'
AND notes = '$notes'
AND removed = '$removed'
AND staffid= '$sid'
ORDER BY magnum, sect, slidenum
");
while ($getlocationsrow = $getlocations->fetch()) {
extract($getlocationsrow);
$magrange[]=array("$magnum", "$sect", "$slidenum");
}
function rangeslides($arr) {
$previous = null;
$result = array();
$consecutiveArray = array();
// Slice array by consecutive sequences
foreach($arr as $number) {
if ($number == $previous + 1) {
$consecutiveArray[] = $number;
} else {
$result[] = $consecutiveArray;
$consecutiveArray = array($number);
}
$previous = $number;
}
$result[] = $consecutiveArray;
// Get length of each sub array
$count = array_map('count', $result);
$first = reset($count);
$last = end($count);
prettyarray($result);
}
I want to extract data from the array to look like this showing the first and last numbers in the range:
19.0001.2 1 - 12
The above array should produce 15 different results with 9 of them showing no range of numbers because they are singular.
ie: 19.0001.8 4 40

How do I use array_map recursively in PHP?

I am attempting to convert an associative array to a 2D array to allow me to export it to Google Sheets. I've figured out a simplistic solution that works as follows:
$headers = $data["resultSets"][0]["headers"];
$rowSet0 = $data["resultSets"][0]["rowSet"][0];
$rowSet1 = $data["resultSets"][0]["rowSet"][1];
$hackresults = array_map(null, $headers, $rowSet0, $rowSet1);
This produces the following:
(
[0] => Array
(
[0] => SEASON_ID
[1] => 22017
[2] => 22017
)
[1] => Array
(
[0] => Player_ID

This is the output I'm looking for, but there are 27 "rowSet"s, and it seems there must be a recursive way of performing this task.
I've looked at a number of custom array_map_recursive style functions but haven't had any success. Apologies and thanks in advance, I am a terrible novice coder!

You can use argument unpacking.
With the ... operator, you can use all the elements under $data["resultSets"][0]["rowSet"] as additional arguments to array_map.
$headers = $data["resultSets"][0]["headers"];
$rowSets = $data["resultSets"][0]["rowSet"];
$results = array_map(null, $headers, ...$rowSets);
(This isn't recursion, but I think it does what you're trying to do.)

How to change this kind of array arrangement into like this

I want that array to form like this:
$example_data = array(
array('00',1,12,1),//bing,google,yahoo
array('01',0,7,0),
array('02',0,5,0),
array('03',1,4,0),
array('04',0,7,0),
array('05',0,5,1),
array('06',1,2,0),
array('07',0,7,0),
array('08',1,8,0),
array('09',0,13,0),
array('10',1,19,1),
//should have more arrays in here, but I hope you got my point...
);
So basically, all the 00 of bing,google, and yahoo is being grouped by on a single array, then the other 01,02,03,etc.. are to be grouped by on a single array again.
So if you noticed that we have a zero on this array array('01',0,7,0), it because bing doesn't have a 01 value in the array, and yahoo also doesn't have a 01 value in the array, except for google which has a 01 that has a value of 7.
Any help how to transform this kind of array to the one I posted.
Your help will be greatly appreciated! Thanks!

I managed to answer it on my own, not sure if this is efficient but it works! :)
//$new variable is the array that I the google analytics api returned
foreach($new as $key => $value){
if($value[1] == 'bing')
$combine['bing'][$value[0]] = $value[2];
if($value[1] == 'google')
$combine['google'][$value[0]] = $value[2];
if($value[1] == 'yahoo')
$combine['yahoo'][$value[0]] = $value[2];
}
$example_data = array();
for($i=0;$i<=23;$i++){
$tempI = $i;
if($i < 10)
$tempI = "0".$i;
$bing = 0;
$google = 0;
$yahoo = 0;
if(isset($combine['bing'][$tempI])){
$bing = $combine['bing'][$tempI];
}
if(isset($combine['google'][$tempI])){
$google = $combine['google'][$tempI];
}
if(isset($combine['yahoo'][$tempI])){
$yahoo = $combine['yahoo'][$tempI];
}
//time,bing,google,yahoo
$example_data[$i][0] = $tempI;

Thanks again StackOverflow! :)

How about this:
<?php
$initial = [
[ '00', 'bing', 1 ],
[ '00', 'google', 12 ],
[ '00', 'yahoo', 1 ],
[ '01', 'google', 7 ],
[ '02', 'google', 5 ],
[ '03', 'bing', 1 ],
[ '03', 'google', 4 ],
];
$searchEngines = ['bing', 'google', 'yahoo' ];
$temp = [];
foreach ( $initial as $data )
{
// Create array of the type $data['00']['google'] = 12
$temp[ $data[0] ][ $data[1] ] = $data[2];
}
$final = [];
// Now go over the newly created array
foreach( $temp as $code => $entry )
{
// Initialize a new array holding initially that $code ( I don't know if $code is correct term though )
$temp2 = [ $code ];
// And now for each of the defined search engines
foreach( $searchEngines as $se )
{
// Check if we have a value set

And if someday you decide to add another search engine to the list all you'll have to do will be to add it to the $searchEngines array.

Replace numeric array keys with associative keys from array

I have a dataset similar to this in which I am trying to replace the numeric key values within DATA to the corresponding values in COLUMNS. I can do this in a loop but I don't think I'm doing it in the most efficient way possible. Can anyone suggest any nice functions that I haven't considered to accomplish this?

foreach ($data->DATA as $key => $array) {
$data->DATA[$key] = array_combine($data->COLUMNS, $array);
}
$data is the object you showed.
Loop trough the data and combine the keys with the data, see array_combine

$data->DATA = array_map(function (array $entry) use ($data) {
return array_combine($data->COLUMNS, $entry);
}, $data->DATA);

Is this the correct syntax for 'array_unique()' in PHP?

I want to get rid of duplicates in my array but I'm still printing duplicates with this:
$getuser = ltrim($top10['url'], " users/" ); //trim url to get user id
$array[$i++] = $getuser;
$dirty = $array;
$clean = array_unique($dirty);
print_r($clean)."<br />";
Input print_r($array)

Yes, it seems to be correct. Basically you specify an array to array_unique and it gives you unique items out of the array.
$unique_array = array_unique($your_array);
