Build array by string name OR make multiple array by string values - php

I want to build a array or multiple array by breaking the main array , and my array is like ,
Array
(
[0] => string1
[1] => 1
[2] => 2
[3] => 3
[4] => 66
[5] => 34
[6] => string1
[7] => aww
[8] => brr
[9] => string3
[10] => xas
)
So basically by the value 'string1' i want to make a new array or first array which has only those three values (1,2,3) and same for string2 and string3,So each array has its values(three).
Please help me to build this.
Note: those all string names will be static.
Thank you in advance.
Result should me like:
string1 array:
<pre>Array
(
[1] => 1
[2] => 2
[3] => 3
[4] => 66
[5] => 34
)
string2 array:
<pre>Array
(
[1] => aww
[2] => brr
)
string3 array:
<pre>Array
(
[1] => xas
)

This I think will get you what you want.
It does assume that the first entry in the old array will be a keyword!
$old = array('string1',1,2,3,66,34,'string2','aww','brr','string3','xas');
$new = array();
$keywords = array('string1', 'string2', 'string3');
$last_keyword = '';
foreach ($old as $o) {
if ( in_array($o, $keywords) ) {
$last_keyword = $o;
} else {
$new[$last_keyword][] = $o;
}
}
print_r($new);
It creates a new array like this
Array
(
[string1] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 66
[4] => 34
)
[string2] => Array
(
[0] => aww
[1] => brr
)
[string3] => Array
(
[0] => xas
)
)
However I still maintain that it would be better to go back to where the original array gets created and look to amend that process rather than write a fixup for it

How to add values to an array inside an array obtained through AJAX

In my PHP file, I'm receiving a total of 4 variables $data, $date, $shift and $val1.
$data is an array and the other 3 are date and 2 strings obtained through AJAX with no problem.
What I'm trying to do is to insert these 3 values inside my $data variable.
I tried using array merge, and a For each loop with multiple instances but no luck so far.
I obtained my variables like this:
if (isset($_POST['date'])){
$date = $_POST['date'];
$date = json_encode($date);
$date = json_decode($date);
}
if (isset($_POST['shift'])){
$shift = $_POST['shift'];
$shift = json_encode($shift);
$shift = json_decode($shift);
}
if (isset($_POST['val1'])){
$val1 = $_POST['val1'];
$val1 = json_encode($val1);
$val1 = json_decode($val1);
}
if (isset($_POST['data'])){
$dat = $_POST['data'];
$data = json_decode($dat, true);
}
$values = array($date,$shift,$val1);
$r = (array_merge($data, $values));
My data array looks something like this:
Array (
[0] => Array (
[data] => Array (
[0] => Array (
[0] => 1
[1] => 2
[2] => 3
[3] => 0
[4] => Mat1
[5] => Box1
[6] => 100
[7] => 100
[8] => Piece1
[9] => Loc1
[10] => Mach1
[11] => 1000
[12] => Accepted
)
)
)
[1] => 2019-04-09
[2] => First
[3] => Value1
)
But what I want to achieve is this:
Array (
[0] => Array (
[data] => Array (
[0] => Array (
[0] => 1
[1] => 2
[2] => 3
[3] => 0
[4] => Mat1
[5] => Box1
[6] => 100
[7] => 100
[8] => Piece 1
[9] => Suc1
[10] => Mach1
[11] => 1000
[12] => Accepted
[13] => 2019-04-09
[14] => First
[15] => Value1
)
)
)
)
What am I doing wrong? Or How can I achieve what I'm trying to do?
Edit: Since I can get more than one array at my array, something like this
Array (
[0] => Array (
[data] => Array (
[0] => Array (...)
[1] => Array (...)
[2] => Array (...)
[3] => Array (...)
)
)
)
I just added this code to #HelgeB answer, I'm leaving it here in case someone might need it in the future.
$count = count($data[0]['data']);
for ($i=0; $i < $count ; $i++) {
$data[0]['data'][$i][] = $date;
$data[0]['data'][$i][] = $shift;
$data[0]['data'][$i][] = $val1;
}
As far as I can see from your merged output, your $data array structure is $data[0]['data'][0] = [1,2,3,...,'Accepted'].
So in my opinion you need to insert the values exactly on the level $data[0]['data'][0] to obtain your result.
The simplest way to achieve this would be:
$data[0]['data'][0][] = $date;
$data[0]['data'][0][] = $shift;
$data[0]['data'][0][] = $val1;
If you want to use your merge approach you need to merge on the correct level like this:
$r = [0 => ['data' => [0 => (array_merge($data[0]['data'][0], $values))]]];

How to retrieve data from multiple arrays

I have two arrays that was converted from csv file.
The first csv line looks like this:
franchise_id,franchise_name,phone,website,email,region_codes;
1,"Abbott, Hackett and O`Conner",1-648-177-9510,auto-service.co/bw-319-x,Lupe-2485#auto-service.co,"36101,36055,36071";
The second csv line looks like this:
postal_code,region_code,city,state,region;
14410,36055,Adams Basin,NY,Monroe;
I converted these lines to arrays like this:
//Region Array
$region_lines = explode(PHP_EOL, $region_mappings_string);
$region_array = array();
foreach ($region_lines as $region_line) {
$region_array[] = str_getcsv($region_line);
}
//Franchise Array
$franchise_lines = explode(PHP_EOL, $franchises_string);
$franchise_array = array();
foreach ($franchise_lines as $franchise_line) {
$franchise_array[] = str_getcsv($franchise_line);
}
After that I got the result like this for Region:
Array
(
[0] => Array
(
[0] => postal_code
[1] => region_code
[2] => city
[3] => state
[4] => region;
)
[111] => Array
(
[0] => 14410
[1] => 36055
[2] => Adams Basin
[3] => NY
[4] => Monroe;
)
[112] => Array
(
[0] => 14617
[1] => 36055
[2] => Rochester
[3] => NY
[4] => Monroe;
)
And for franchise:
Array
(
[0] => Array
(
[0] => franchise_id
[1] => franchise_name
[2] => phone
[3] => website
[4] => email
[5] => region_codes;
)
[1] => Array
(
[0] => 1
[1] => Abbott, Hackett and O`Conner
[2] => 1-648-177-9510
[3] => auto-service.co/bw-319-x
[4] => Lupe-2485#auto-service.co
[5] => 36101,36055,36071;
)
What I need to do is to look for 14410 postal code from the first array, get the region_code and look for this region_code in second array and then output the results in PHP. How can this be done?
Will have to loop over franchises array and run simple comparison
function getDataByRegionCode($code, $franchiseArray) {
foreach ($franchiseArray as $key => $data) {
if(isset($data[5])){
$codes = explode(',',$data[5]);
if(in_array($code,$codes)) return $data;
}
}
return NULL;
}
print_r(getDataByRegionCode(14410,$franchiseArray));

Split an array into a MD array every nth line

bit of a question here. Ive got an array that contains data which has been parsed from a website using all our favourite php functions such as array_map.
The array is current 3 sub arrays deep.
Here is the code I am using:
for ($tcid = 1; $tcid <= count($categories); $tcid++) {
$catHeader[$tcid] = $categories[$tcid][0];
$event[$i]['tickets'] = $categories;
unset($categories[$tcid][0]);
$categories[$tcid] = array_map('trim', $categories[$tcid]);
$categories[$tcid] = array_values($categories[$tcid]);
$ab = 0;
for ($b = 0; $b <= count($categories[$tcid]); $b++) {
if ($categories[$tcid][$b] == "" || !$categories[$tcid][$b] || $categories[$tcid][$b] == null) {
unset($categories[$tcid][$b]);
}
}
}
and the array looks something like....
[1] => Array (
[data] => Array ( ...
)
[tickets] => Array (
[1] => Array (
[0] => xxx
[1] => etc
[3] => etc2
)
[2] => (
[0] => Std1
[1] => 10 / 10
[2] => £20.00
[3] => £200.00
[4] => Std2
[5] => 100 / 100
[6] => £13.00
[7] => £1,300.00
[8] => Std3
[9] => 10 / 320
[10] => £15.00
[11] => £150.00
)
)
)
My question to you today, is how on earth do I split the array every 4 \n's or array keys as they're known and explode each 4 into a further sub array?
So that Std1, Std2, Std3 will be their own sub array with its associated data of the 2nd key of tickets, but also doing this for every sub array of tickets that has more than 1 set of data (a set of data being 4 array keys).
I've tried all sorts but can't get it to work.
See below of how I want it to look.
[1] => Array (
[data] => Array ( ...
)
[tickets] => Array (
[1] => Array (
[0] => xxx
[1] => etc
[3] => etc2
)
[2] => (
[0] => Array (
[0] => Std1
[1] => 10 / 10
[2] => £20.00
[3] => £200.00
)
[1] => Array (
[0] => Std2
[1] => 100 / 100
[2] => £13.00
[3] => £1,300.00
)
[2] => Array (
[0] => Std3
[1] => 10 / 320
[2] => £15.00
[3] => £150.00
)
)
)
)
Thanks
As noted in the comments, you'd be best off handling your array by-reference to modify it's original contents somewhere within your loops
Provided the array groupings you want to chunk are in groups of 4, you could array_chunk() it:
$array['tickets'][2] = array_chunk($array['tickets'][2], 4);

Check values of sub-arrays, use key as new value in new array - PHP

I have an array, let call it $mainArray, which looks like this: -
Array
(
[1] => Array
(
)
[5] => Array
(
[0] => 10
[1] => 15
[2] => 20
[3] => 25
)
[80] => Array
(
[0] => 20
[1] => 40
[2] => 50
[3] => 60
)
[777] => Array
(
[0] => 100
[1] => 200
[2] => 300
[3] => 400
)
[666] => Array
(
[0] => 1234
[1] => 5678
[2] => 20
[3] => 9865
)
[555] => Array
(
[0] => 111
[1] => 222
[2] => 333
[3] => 444
)
)
What I want to do is create 2 new arrays: -
1) Where values are equal to the key names of $mainArray, but only those where the sub-array (if there is one) contains the value "20" somewhere in it. For example my new array (call it $arrayOne) will be [0] => 5, [1] => 80, [2] => 666.
2) Similar to above, but where there's either no sub-array or, if there is, it doesn't include "20" as a value. So that (call it $arrayTwo) would be [0] => 1, [1] => 777, [2] =>555.
I've tried loads of for each loops and even a little RecursiveIteratorIterator (whatever that is!) but can't seem to reference keys and values in the way that I need to. Any help would be much appreciated!
Will this do?:
<?php
foreach( $mainArray as $mKey => &$mVal )
{
if( in_array( 20, $mVal ) )
{
$arrayOne[] = $mKey;
}
else
{
$arrayTwo[] = $mKey;
}
}
I trust you can create a function which would check if array contains 20 as it's value or not. Let's call this function has20.
You two new arrays would then be array_filter($mainArray, 'has20') and array_filter($mainArray, function ($x) {return !has20($x);})
You can do it like this:
$newArray = array();
foreach($mainArray as $key => $subArray) {
if (in_array(20, $subArray)) {
$newArray[] = $key;
}
}

Match array elements beginning with letters specified in another array in PHP

I have the following array:
Array
(
[0] => BCD
[1] => ACE
[2] => AHP
[3] => BGH
[4] => ART
[5] => COT
[6] => ARG
[7] => BGT
)
I need to match all elements whose first letter is in the following array:
Array
(
[0] => B
[1] => A
)
to get:
Array
(
[0] => ACE
[1] => AHP
[2] => BGH
[3] => ART
[4] => ARG
[5] => BGT
)
Short of looping through the whole array, how do I do this in PHP? Is there a built-in PHP array function for this or a combination of so? The order does not matter for both keys and values of the resulting array. Thanks much.
You can use array_filter for these operations:
$array = array('CBD', 'NHN', 'NHP', 'WHC', 'NND', 'CQN', 'WST', 'WVT');
$whitelist = array('W', 'N');
$filtered = array_filter($array, function($val) use ($whitelist) {
// check if first letter is in the whitelist array
if (in_array($val{0}, $whitelist)) {
return $val;
}
return false;
});
Output:
Array
(
[1] => NHN
[2] => NHP
[3] => WHC
[4] => NND
[6] => WST
[7] => WVT
)
