Use Array data in another function - php

Question

I am hoping I can get some assistance with some issues I'm trying to get the array data from one function to be used in another function.
So in the function that's creating the array data, it looks like this:
function wlp_generate_pdf_and_save( $data, $post_id ){
// Function needing array data
}
function wlp_generate_preview($data, $generateType){
$out_product_brands = array();
if( count($all_posts) > 0 ){
foreach( $all_posts as $s_post )
{
...
$out_product_brands[] = array( 'brand' => vooHelperNew::get_posts_products( $s_post->ID ) );
...
}
}
}
This function "wlp_generate_preview" works perfectly, but it's this $out_product_brands data i need to use in the function (wlp_generate_pdf_and_save) above this one.
Does the order the functions are place change anything?

Answer 1

Return the data from wlp_generate_preview then pass it as a parameter of wlp_generate_pdf_and_save

Answer 2

First you want to return the array from your first function and then send that as a variable to the second function:
<?php
function wlp_generate_pdf_and_save( $data, $post_id, $input_array ){ //added a third
varible to this functions input
// Function needing array data
}
function wlp_generate_preview($data, $generateType){
$out_product_brands = array();
if( count($all_posts) > 0 ){
foreach( $all_posts as $s_post )
{
...
$out_product_brands[] = array( 'brand' => vooHelperNew::get_posts_products( $s_post->ID ) );
...
}
}
return $out_product_brands;//Returned The array
}
And then when calling your functions you might do something like this:
$input_array = wlp_generate_preview($data, $generateType);//Calls the first function
wlp_generate_pdf_and_save($data, $post_id, $input_array);//The third variable passes it into the next function
