Adding dynamic array to the end of a static array PHP - php

Question

I've got the following code which is within a sql loop to determine how many rows i output onto a spreadsheet. Basically without pasting the full thing as it's quite a lengthy statement, the top SQL statement will return 60 rows, which will contain the variables I enter into the original $data1 array.
$stmt2= $mysqV1->prepare("SELECT DISTINCT master_recipe, recipe, matl_id, comp_length, comp_width, comp_tck from components where recipe > 0 and matl_id > 0 order BY CAST(recipe AS UNSIGNED) ASC" );
foreach ($result2 as $key2=>$value2)
{
$data1[]=(array("Master Recipe"=>$master_recipe,"Recipe"=>$recipe,"Recipe Name"=>$recipe_name,"Material"=>$material,"Length"=>$comp_length,"Width"=>$comp_width,"Thickness"=>$comp_tck));
}
I then have a further nested loop (inside the original $result2 loop) which will determine how many elements i add to that array, as the value will change from record to record. I have tried to declare an array then use array push and array merge but neither of them seem to do what i want.
$temp7 = array($master_recipe);
$stmt7= $mysqV1->prepare("Select * from machine where master_recipe = ? order by route_header_id asc" );
$stmt7->execute($temp7);
$result7=$stmt7->fetchAll();
foreach ($result7 as $key7=>$value7)
{
$station_id = $value7['route_header_id'];
$time_taken = $value7['time_hrs'];
$a[] = (array("StationID"=>$time_taken));
array_push($data1,$a);
}
So what I would like this to do is add the contents of $a to the end of $data1 to give me 1 array value which then prints out to my spreadsheet(the print part is already working for the $data1 array) but it's not adding the $a to it.
Final result I would like to end up something like this for the value in $data1
$data1[]=(array("Master Recipe"=>$master_recipe,"Recipe"=>$recipe,"Recipe Name"=>$recipe_name,"Material"=>$material,"Length"=>$comp_length,"Width"=>$comp_width,"Thickness"=>$comp_tck,"$station_id1"=>$time_taken,"$station_id2"=>$time_taken2,"$station_id3"=>$time_taken3));

Answer 1

Put the row that you're adding to $data1 in the $a variable, then you can add new elements to that row before you push it into $data1.
foreach ($result2 as $value2) {
$master_recipe = $value2['master_recipe'];
$recipe = $value2['recipe'];
...
$a = array("Master Recipe"=>$master_recipe,"Recipe"=>$recipe,"Recipe Name"=>$recipe_name,"Material"=>$material,"Length"=>$comp_length,"Width"=>$comp_width,"Thickness"=>$comp_tck);
$temp7 = array($master_recipe);
$stmt7= $mysqV1->prepare("Select route_header_id, time_hrs from machine where master_recipe = ? order by route_header_id asc" );
$stmt7->execute($temp7);
while ($value7 = $stmt7->fetch())
{
$station_id = $value7['route_header_id'];
$time_taken = $value7['time_hrs'];
$a[$station_id] = $time_taken;
}
$data1[] = $a;
}

Answer 2

What if you change your initial set of $data1 to this:
$data1= array(
"Master Recipe"=>$master_recipe,
"Recipe"=>$recipe,
"Recipe Nme"=>$recipe_name,
"Material"=>$material,
"Length"=>$comp_length,
"Width"=>$comp_width,
"Thickness"=>$comp_tck
);
then, in your loop..
foreach ($result7 as $key7=>$value7)
{
$station_id = $value7['route_header_id'];
$time_taken = $value7['time_hrs'];
$data1[$station_id] = $time_taken;
}
