I have array structure like this,
Array
(
[1] => Array
(
[1] =>
[2] =>
[3] =>
[4] => Product
[5] => Product Name
..
[59] => Color
)
[2] => Array
(
[1] =>
[2] =>
[3] => 1
[4] => 9155
....
[59] =>
)
[3] => Array
(
[1] =>
[2] =>
[3] => 1
[4] => 9165
...
[59] => Green
)
[4] => Array
(
[1] =>
[2] =>
[3] =>
[4] =>
...
[58] =>
[59] =>
)
)
Its reading data from Excel sheets , the issue is when i read data from excel sheet it reads empty rows too, I already tried to ignore empty rows from the excel sheet some how its working (when the excel is created from MSexcel ) but from Google Drive its reading empty rows. So I would like to remove those rows with 1- 59 are blanks. in the above example array with index 4 .
Note that some index have missing values in many sub index but I don't want to remove those, only all sub indexes from 1-59 are blank then that main index (here its 4) needs to remove.
Is there any smart way to remove those array index that have empty values. I not like to iterate all the array and store to another.
if you want to remove the index 4 that is an empty array :
array_filter(array_map('array_filter', $array));
Use array_map
$array = array_map('array_filter', $array);
let try with array_filter
$entry = array(
0 => 'foo',
1 => false,
2 => -1,
3 => null,
4 => ''
);
print_r(array_filter($entry));
Array
(
[0] => foo
[2] => -1
)
Use array_filter..It will remove all empty values..
array_filter($array);

So this is how my Array ($dataArray) looks oks like:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 10:45:43
[2] => 237
[3] => Some text from
[4] => Client 1
)
[2] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)
[3] => Array
(
[0] => 2021-12-01
[1] => 11:53:03
[2] => 44
[3] => anonymous
[4] => Client 1
)
I need to Loop trough it to search the Client Names, and if i find the matching name in the Element 4 then delete the entire Array.
$ExportKDname = "Client 1"
foreach($dataArray as $key => $sub_array) {
if($sub_array[4] == $ExportKDname) {
unset($dataArray[$key]);
break;
}
}
print_r($dataArray);
But with this code none of the arrays will be deleted. And I just can not find the right way to do it.
The Final array what I need to look like if we find the "Client 1" in the array would be like this:
Array
(
[0] => Array
(
[0] => Date
[1] => Time
[2] => Duration
[3] => Info
[4] => Client
)
[1] => Array
(
[0] => 2021-12-01
[1] => 11:29:13
[2] => 77
[3] => Nothing important
[4] => Client 2
)
In the if condition you are saying "if u match with $sub_arr[4] == $ExportKDname unset it and stop the loop". the machine doing that. when it matched first time it removes and stoping. If u wanna delete all match do not write break; let it continue. So delete or make it comment break; line.
You can array_filter your variable and check if value is in_array.
With PHP 7.4+ syntax it should look like this:
$result = array_filter($dataArray, fn ($innerArray) => !in_array('Client 1', $innerArray));
I have the following array :
Array
(
[0] => Array
(
[Name] => first_data
[building] => A
[apt] => 16
)
[1] => Array
(
[Name] => first_data
[building] => B
[apt] => 16
)
[2] => Array
(
[Name] => second_data
[building] => A
[apt] => 17
)
[3] => Array
(
[Name] => second_data
[building] => B
[apt] => 18
)
and I need it to be returned as :
Array
(
[0] => Array
(
[Name] => first_data
[A] => 16
[B] => 16
)
[1] => Array
(
[Name] => second_data
[A] => 17
[B] => 18
)
Any ideas?
BTW the first array has hundreds of entries (not only first_data, but second and etc...) plus it has more than A and B.
Thanks in advance.
Not exactly what you want, but if you instead index the new array by the name, you can do this very easily. If the index number is some kind of ID, you can just create a field for it
foreach ( $oldarray as $index => $piece )
{
$newarray[$piece['Name']] = array($piece['building'] => $piece['apt'])
}
This will give you
Array
(
['first_data'] => Array
(
['A'] => 16,
['B'] => 16
)
['second_data'] => Array
(
['A'] => 17,
['B'] => 18
)
)
Since you have two entries with the same new, when you hit the 2nd loop, it will simply add the other building name. If you can work with this layout, then your solution is very easy, it will take more steps to do it exactly as you showed. If you absolutely have to do it the way you showed, you need extra code to loop through the new array, find the building name, add the key in the correct place, but this will be slower if you have a large amount of data.
In my opinion, the way I presented it is a far easier way to look around the array too. If you wanted to know the apt value for A in "second_data" you can just do
$newarray['second_data']['A']
with your array layout, it would require a loop to search the array for "second_data" because you have no idea where it is.
Given this array:
Array
(
[0] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[1] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[2] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
[3] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
)
The ssm_featured_post_id value corresponds to the value of the array items in the second array.
I want to order the first array items in the same order as the items in the second array
Array
(
[1] => 63
[0] => 70
[3] => 1
[2] => 49
)
so the result after sorting would be
Array
(
[0] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[1] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[2] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
[3] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
)
The simpler way would be to use usort and write a function that uses the second table to compare two values from first table.
You may want to check out array_multisort, particularly the third example given. The idea is that you create arrays based on the "columns" of the multidimensional array, then sort them simultaneously, and put the result back in the original array.
This is the example array I get sent from the CMS to Smarty.
[field] => Array
(
[value] => 19
[options] => Array
(
[labels] => Array
(
[0] => --- Select ---
[1] => John
[2] => Mark
[3] => Luke
[4] => Philip
)
[values] => Array
(
[0] =>
[1] => 15
[2] => 1
[3] => 19
[4] => 17
)
)
So I would normally write {$field.value} or {html_options values=$field.options.values output=$field.options.labels selected=$field.value}
My question is how can I easily get the label from the value. I tried this: {$field.options.labels[$field.value]} but then realise this is just going to get the index of the array and not the value.
I know you could do this in a {foreach/if} but that is going to get messy in the template. Is there a way to write a plugin for this?
Without foreach loop it can be done in one-liner:
{$field.options.labels[$field.value|array_search:$field.options.values]}
Or modifier:
function extractLabel($field){
$idx = array_search($field['value'], $field['options']['values']);
if($idx !== FALSE && isset($field['options']['labels'][$idx])){
return $field['options']['labels'][$idx];
}
}
$smarty->registerPlugin('modifier', 'extractLabel', 'extractLabel');
tpl:
{$field|extractLabel}
I am working on a function that submits multiple records on various relationship types. The main issue I am running into is the format of the array. In order for my saveAll() to work on my multiple relationships setup, the array needs to be in this format as you can see the models are Keys (first array below).
My main question is: 1) Is it possible to strip the numerical indexes off the second layer of the second array below?
I am returning my input fields like so. You can see the prefixed counter (which I believe is what is creating the numeric index on that second level).
<?php echo $this->Form->input("$i.monthly_cost", array('label' => 'Monthly Cost')); ?>
I am using a for loop counter for the fields. So my question number to is: can this for value be changed to something that will work with Cake's saveAll()?
<?php for ($i = 1; $i <= 2; $i++) { ?>
Example where models are the keys (this is the format I need):
Array
(
[User] => Array
(
[username] => billy
)
[Profile] => Array
(
[sex] => Male
[occupation] => Programmer
)
The only output I can get on my multiple input array (below is the debug() dump)
My actual output is numerically indexed:
Array
(
[Plan] => Array
(
[1] => Array
(
[plan_detail_id] => 36
[monthly_cost] => 0
[dental_cost] => 0
[age_id] => 14
[applicant_id] => 1
[state_id] => 1
)
[2] => Array
(
[plan_detail_id] => 36
[monthly_cost] => 0
[dental_cost] => 0
[age_id] => 2
[applicant_id] => 4
[state_id] => 1
)
)
[1] => Array
(
[1] => Array
(
[Zip] => Array
(
[0] => 487
[1] => 486
[2] => 485
[3] => 484
[4] => 483
)
)
)
[2] => Array
(
[2] => Array
(
[Zip] => Array
(
[0] => 485
[1] => 484
[2] => 483
)
)
)
)
Did you already check out the Set Core Utility Library? This can help you out a lot with array management.
