Merging arrays that are inside a foreach loop using PHP - php

Question

I have following array:
Array
(
[0] => ALFA01
[1] => BETA02
[2] => GAMMA03
[3] => DELTA04
[4] => EPSILON05
[5] => ZETA06
[6] => THETA07
[7] => IOTA08
[8] => KAPPA09
[9] => LAMBDA10
)
Then I separate the values into characters and numbers in the following way:
foreach($portfolio as $value) {
$char = substr("$value", 0, 2);
$numb = substr("$value", 2);
and do a query using this values:
$query = "
SELECT id, typ1, typ2, typ3
FROM data_table
WHERE char = '$char'
AND numb = $numb
LIMIT 1";
$result = mysqli_query($mysqli, $query);
//Now we have some important variables that will help finding our result.
while($row = mysqli_fetch_array($result)) {
$id = $row['id'];
$typ1 = $row['typ1'];
$typ2 = $row['typ2'];
$typ3 = $row['typ3'];
}
Then I do some queries in case typ* are = 1 (it can be only 0 or 1).
if ($typ1 == 1) {
$query_id_num2 = "
SELECT id_num2
FROM values_table01
WHERE id_num1 = $id";
$result_id_num2 = mysqli_query($mysqli, $query_id_num2);
// Return an array with all ids.
$id_num2_typ01 = array();
while($row = mysqli_fetch_array($result_appln_id_num2)) {
$id_num2_typ01[] = ($row['id_num2']);
}
}
/== EDIT ==/
In each different typ we have a different values_table.
I'm now writing the complete query for typ2, so it will be emphasised.
// == /EDIT ==/
Then I do the same to typ2 and typ3...
if ($typ2 == 1) {
$query_id_num2 = "
SELECT id_num2
FROM values_table02
WHERE id_num1 = $id";
$result_id_num2 = mysqli_query($mysqli, $query_id_num2);
// Return an array with all ids.
$id_num2_typ02 = array();
while($row = mysqli_fetch_array($result_appln_id_num2)) {
$id_num2_typ02[] = ($row['id_num2']);
}
}
etc.
In the end I merge the three arrays (if they are set) and print the result on the screen:
// typ01
if (isset($id_num2_typ01)){
$id_num2_typ01 = $id_num2_typ01;
} else {
$id_num2_typ01 = array();
}
// typ02
if (isset($id_num2_typ02)){
$id_num2_typ02 = $id_num2_typ02;
} else {
$id_num2_typ02 = array();
}
// typ03
if (isset($id_num2_typ03)){
$id_num2_typ03 = $id_num2_typ03;
} else {
$id_num2_typ03 = array();
}
// merge arrays
$id_num2 = array_merge($id_num2_typ01,$id_num2_typ02,$id_num2_typ03);
// print it on screen
echo '<pre>id_num2:<br />';
print_r($appln_idNum2);
echo '</pre>';
} // this closes the above foreach, i.e. the code will loop to every value of the first array
As result I receive for example following data:
id_num2:
Array
(
[0] => 41558194
[1] => 44677841
[2] => 44503689
[3] => 40651770
[4] => 41667291
)
id_num2:
Array
(
[0] => 15458354
[1] => 35477154
[2] => 15703123
[3] => 95151111
[4] => 55567125
)
etc.
In our case we will have 10 small arrays like that.
My problem is: How can I merge this small arrays so in the ende I have only one array?
Thank you for your help to solve this particular problem. Maybe is there also another possibility to write the code to be better and more efficient.
