Remove Duplicated Values From Array - PHP - php

Question

What I want to achieve
I want to make as many arrays as the number of the secondArray (in this particular case: 2) only if the value is 1
I have the array firstArray.
firstArray
(
[analysis] => coding
[data] => Array
(
[data1] => Array
(
[0] => Array
(
[name] => "test"
)
)
[data2] => Array
(
[0] => Array
(
[age] => 22
)
)
[data3] => Array
(
[0] => Array
(
[CODE] => 1111 //Stable
[QUANTITY] => 1
)
)
)
)
My second array is secondArray
secondArray
(
[0] => Array
(
[test1] => 1
[test2] => 1
[test3] => 1
[test4] => 1
)
[1] => Array
(
[test1] => 1
[test2] =>
[test3] => 1
[test4] =>
)
)
What I want to achieve
I want to make as many arrays as the number of the secondArray (in this particular case: 2) only if the value is 1
The result must be:
firstArray
(
[analysis] => coding
[data] => Array
(
[data1] => Array
(
[0] => Array
(
[name] => "test"
)
)
[data2] => Array
(
[0] => Array
(
[age] => 22
)
)
[data3] => Array
(
[0] => Array
(
[CODE] => 1111 //Stable
[QUANTITY] => 1
)
[1] => Array
(
[CODE] => 0001
[QUANTITY] => 1
)
[2] => Array
(
[CODE] => 0002
[QUANTITY] => 1
)
[3] => Array
(
[CODE] => 0003
[QUANTITY] => 1
)
[4] => Array
(
[CODE] => 0004
[QUANTITY] => 1
)
)
)
)
and second firstArray must be
firstArray
(
[analysis] => coding
[data] => Array
(
[data1] => Array
(
[0] => Array
(
[name] => "test"
)
)
[data2] => Array
(
[0] => Array
(
[age] => 22
)
)
[data3] => Array
(
[0] => Array
(
[CODE] => 1111 //Stable
[QUANTITY] => 1
)
[1] => Array
(
[CODE] => 0001
[QUANTITY] => 1
)
[2] => Array
(
[CODE] => 0003
[QUANTITY] => 1
)
)
)
)
the code I am currently working on is, but I do not get the desired result. the second firstArray also prints the values of the first firstArray
foreach ($secondArray as $key => $value) {
if($key == 'test1' && $value == "1"){
array_push($firstArray ['data']['data3'],
array('CODE' => "0001",
'QUANTITY' => "1"
)
);
}
if($key == 'test2' && $value == "1"){
array_push($firstArray ['data']['data3'],
array('CODE' => "0002",
'QUANTITY' => "1"
)
);
}
if($key == 'test3' && $value == "1"){
array_push($firstArray ['data']['data3'],
array('CODE' => "0003",
'QUANTITY' => "1"
)
);
}
if($key == 'test4' && $value == "1"){
array_push($firstArray ['data']['data3'],
array('CODE' => "0004",
'QUANTITY' => "1"
)
);
}
}

You could write for example a nested foreach and check if the key starts with test instead of hardcoding all the different keys.
Then increment a variable for the value of CODE and use for example a padding for the leading zeroes.
$firstArray = [
"analysis" => "coding",
"data" => ["data1" => [["name" => "test"]], "data2" => [["age" => 22]], "data3" => [["CODE" => 1111, "QUANTITY" => 1]]]
];
$secondArray = [
["test1" => "1", "test2" => "1", "test3" => "1", "test4" => "1"],
["test1" => "1", "test2" => "", "test3" => "1", "test4" => ""]
];
$result = [];
foreach ($secondArray as $sa) {
$code = 1;
$tmp = $firstArray;
foreach ($sa as $key => $value) {
if (substr($key, 0, 4) === "test" && $value === "1") {
$tmp["data"]["data3"][] = [
"CODE" => str_pad($code, 4, "0", STR_PAD_LEFT),
"QUANTITY" => 1
];
}
$code++;
}
$result[] = $tmp;
}
foreach ($result as $r) {
print_r($r);
}
Instead of substr to check the first 4 characters to start with test you could also make the check more specific and check for test followed by 1 o more digits using:
if (preg_match("/^test\d+$/", $key) && $value === "1") {
See a php demo.
