You can create array by this way:
$array = array(
'category_1' => 'value',
'category_2' => array(
'subcategory_1' => 'value',
'subcategory_2' => 'value',
),
);

My PHP Loop is below
foreach ($retr as $page) {
echo $page['name'];
//var_dump($page);
}
Regards
Your array is multidimentional, being a single element array containing a further 19 child elements.
If you just want to itterate the child elements, then run the loop over the top level elelemt, not the parent array:
foreach ($retr[0] as $page) {...}
I have this flat array that I am trying to turn into a parent-child array:

Here is my recursive function that maps the ids and makes it into a parent-child array:
function buildTree(array $elements, $parentId = 0) {
$branch = array();
foreach ($elements as $element) {
if ($element['parent_id'] == $parentId) {
$children = buildTree($elements, $element['id']);
if ($children) {
$element['children'] = $children;
}
$branch[] = $element;
}
}
return $branch;
}
Here is the output I am getting from the above function:

While the first part of it is correct, it sometimes labels the child arrays as a parent after mapping it correctly the first time. Why are some child arrays being mapped as a parent?
Edit: I'm an idiot, when I calling buildTree() I was not passing in a parentId and just left the value as zero.
I don't know what you want exactly but I have added my code to separate parent and children in array. Please check below code:
function buildTree($elements = array()) {
$branch = array();
if(!empty($elements))
{
foreach ($elements as $element) {
if(!isset($branch[$element['parent_id']]))
{
$branch['parent_id'][]=$element['parent_id'];
$branch[$element['parent_id']]=array();
$branch[$element['parent_id']]['children'][]=$element['id'];
}
else
{
$branch[$element['parent_id']]['children'][]=$element['id'];
}
}
}
return $branch;
}
$arr_rtn = buildTree($arr);
I want to convert this array in a single dimensional flat array without losing the sort order.

Give it try with below function:
function makeOneDimensionArray(array $array, &$res = array())
{
foreach($array as $arr)
{
$res[] = array(
'id' => $arr['id'],
'title' => $arr['title'],
'parent_id' => $arr['parent_id']
);
if(isset($arr['children']))
{
makeOneDimensionArray($arr['children'], $res);
}
}
return $res;
}
$finalArr = makeOneDimensionArray($your_array);
print_r($finalArr);
I have a long array from which I wish to fetch all the values and store it in a separate variable, and store each value in database.

I am able to fetch the outer values of this array by using this code:
if (!empty($array))
{
foreach ($array['categories'] as $category)
{
echo $category['category_id'];
echo "<br>";
}
}
I got values as:
39
40
91
60
15
16
38
57
But I also wish to access the inner most values of the array. Can anyone tell how I can create a nested loop?
If you now how deep your array is you can just simply add other foreach-loops within your main loop.
if (!empty($array))
{
foreach ($array['categories'] as $category)
{
echo $category['category_id'];
echo "<br>";
if(isset($category['categories'])){
foreach($category['categories'] as $category2)
{
echo $category2['category_id'];
echo "<br>";
if (isset($category2['categories'])){
foreach($category2['categories'] as $category3)
{
echo $category3['category_id'];
echo "<br>";
...
} }
}}
}
}

any suggestions on how to make a nested dropdown out of this array ?
i have no idea where to start.....
$HOST="localhost";
$DB="db_dir";
$USER="root";
$PASS="";
mysql_connect($HOST,$USER,$PASS);
mysql_select_db($DB);
function RecursiveCat($pid)
{
static $level=0;
static $strid="";
static $strname="";
$sql=mysql_query("select * from categories where cat_parent =".$pid." ");
//var_dump($sql);
while($row=mysql_fetch_assoc($sql))
{
$id=$row['cat_id'];
$level--;
$pad="";
for($p=1;$p<($level*-1);$p++) $pad.=" > ";
$strname.='<option value="'.$row['cat_id'].'">'.$pad.$row['cat_title'].'</option>';
$rid=RecursiveCat($id);
$strid[]=$row['cat_id'];
$level++;
}
return $strname;
}
<?php echo '<select name="parent">'.'<option value="0">None</option>';
echo RecursiveCat(0);echo '</select>';?>
