How to get data from variable array length? - php

Question

I have this code:
$ItemID = 'a62442e2-ca1f-4fd1-b80d-0d0dc511758e';
$GET_FreeTextFields = new \Picqer\Financials\Exact\ItemExtraField($connection);
$FreeTextFields = $GET_FreeTextFields->filter("ItemID eq guid'$ItemID'", '', '' );
$FreeTextFields01 = array();
$FreeTextFields02 = array();
foreach($FreeTextFields as $GET_FreeTextFields){
$FreeTextFields01[] = $GET_FreeTextFields->Value;
$FreeTextFields02[] = $GET_FreeTextFields->Number;
}
print_r($FreeTextFields01);
print_r($FreeTextFields02);
This outputs:
Value Array
(
[0] => 390
[1] => 804715
[2] => WW001
[3] => WHT/WHT/WHT
[4] => 39/42
[5] => 804715 WW00139/42
[6] => 3pk Quarter Socks
)
Numbers Array
(
[0] => 3
[1] => 4
[2] => 5
[3] => 6
[4] => 7
[5] => 8
[6] => 10
)
What this needs to output:
What i want if i use the first output so with 6 values in the array:
$FreeTextField01 = null
$FreeTextField02 = null
$FreeTextField03 = 390
$FreeTextField04 = 804715
$FreeTextField05 = WW001
$FreeTextField06 = WHT/WHT/WHT
$FreeTextField07 = 39/42
$FreeTextField08 = 804715 WW00139/42
$FreeTextField09 = null
$FreeTextField10 = 3pk Quarter Socks
But with other $ItemID, it can also output:
Value Array
(
[0] => 10100153
[1] => 2007
[2] => 350
[3] => 804082
[4] => WW006
[5] => WHT/NNY/OXGM
[6] => 35/38
[7] => 804082 WW00635/38
[8] => 0,00138857
[9] => Champion 3pk Quarter Socks
)
Numbers Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
[9] => 10
)
What i want is that if a variable is not in the numbers list so 1-10, setting it to empty, and if the numbers is in the numbers array setting that number to the corresponding value variable. For example the number at [0] is 1 then set the variable $FreeTextField1 to $NumbersArray[0]->Value.
I keep making all kinds off loops but i just get stuck at the fact that the array length changes so that [6] can be the number 10 at one $itemID, but at another $ItemID, the number can be 6.
I tried researching this but I don't even know what I have to type in google to find this problem, that's why I'm describing it here.
edit i tried describing it a second time:
Yeah I'm having problems describing what i want, so let me try again. I get two arrays as output one with numbers that correspond with place it stands, as example you have FreeTextField0 thru FreeTextField10. What i tried to do is if (Numbers[0] == 0){ $FreeTextField0 = Value[0]}, but then I get the problem that Numbers[0] can be 3 or something else because if FreeTextField1 is empty i don't get a null value but nothing.
What i want if i use the first output so with 6 values in the array:
$FreeTextField01 = null
$FreeTextField02 = null
$FreeTextField03 = 390
$FreeTextField04 = 804715
$FreeTextField05 = WW001
$FreeTextField06 = WHT/WHT/WHT
$FreeTextField07 = 39/42
$FreeTextField08 = 804715 WW00139/42
$FreeTextField09 = null
$FreeTextField10 = 3pk Quarter Socks

Answer 1

I think this is what you're after but I have to say that I think you're barking up the wrong tree here. You really should not dynamically create variables in your script. To me, it is a serious code-smell and I think you should evaluate your design here.

<?php
// Test case
$values = [
'390',
'804715',
'WW001',
'WHT/WHT/WHT',
'39/42',
'804715 WW00139/42',
'3pk Quarter Socks'
];
$numbers = [3, 4, 5, 6, 7, 8, 10];
// Flip the $numbers array and then use the keys to find the corresponding values in the $values array
$intersection = array_unique(array_intersect_key($values, array_flip($numbers)));
// Fill in the missing keys and use `null` as the value
$output = $intersection + array_fill_keys(range(1,10), null);
// Sort the final output by the keys
ksort($output);
// Format the keys to match FreeTextField{00}
$output = array_combine(
array_map(function($k){ return 'FreeTextField'.str_pad($k, 2, '0', STR_PAD_LEFT); }, array_keys($output)),
$output
);
// Use the extract function to bring all those array keys + values into the symbol table.
// You can now use $FreeTextField01 - $FreeTextField10
extract($output);
var_dump($output);

Answer 2

Use ${$var}
If you want to see a doc about this type of var you can see it here:
