Answer 1

try this:
$array1 = array('category1' =>
array('Company A' =>
array('name', 'city', 'CEO')),
'category2' =>
array('Company B' =>
array('name', 'city', 'CEO')));
foreach ($array1 as $key => $value)
{
foreach ($value as $key1 => $value1)
{
echo "<pre>";
print_r($value1);
echo "</pre>";
}
}
Problem is in your inner foreach loop

Answer 2

There is a problem in inner foreach loop and echo line.
Replace $array_cat by $item and in echo line there is an error:
Cannot use [ ] for reading
By following way, you can achieve your goal.
foreach ($array_cat as $item) {
foreach ($item as $company_display) {
echo $company_display['category']['company']['name'];
}
}

How to create this multidimensional array in PHP
If I would design an array for that, i would do something like this:
$array = array(
//Category 1, nameless i assume?
array(
//Companies
"Company A" => array(
//Company properties
"name" => "My A company",
"city" => "Some city that starts with an A",
"CEO" => "Some CEO that starts with an A"
),
"Company B" => array(
//Company properties
"name" => "My B company",
"city" => "Some city that starts with an B",
"CEO" => "Some CEO that starts with an B"
),
),
//Category two, nameless i assume
array(
//Companies
"Company C" => array(
//Company properties
"name" => "My C company",
"city" => "Some city that starts with an C",
"CEO" => "Some CEO that starts with an C"
),
"Company D" => array(
//Company properties
"name" => "My D company",
"city" => "Some city that starts with an D",
"CEO" => "Some CEO that starts with an D"
),
),
);
Then, if i wanted to get some data out of it, i could do something like this:
$companyAcity = $array[0]['Company A']['city'];
echo $companyAcity;
If I wanted to loop in the array, i could so something like this:
for($categoryID = 0; categoryID < count($array); $i++) {
//Prints data for each category it loops through.
echo $array[$categoryID];
//Loops through the companies contained in the current category where it's looping through
foreach($array[$categoryID] as $companyName => $companyData) {
echo $companyName;
echo $companyData['name'];
}
}
I want to fill an array in a while loop.
If you want to add data to the array while looping in it, you can do something like this:
for($categoryID = 0; categoryID < count($array); $i++) {
$array[$categoryID][] = $categoryID +1;
}
