This is my first time on Stackoverflow so please bear with me if my question is not clear !. I am trying to fetch all rows from tblproperty and loop through the array to convert it into an associative array. Once the property is fetched i am checking if the property is of the page or object. If the property if of the page we add the same in the propertiesArray. If the property is of object I am checking if the object is of the page or child of another parent object. The code below works for 3 levels (meaning Parent > Child > Child > Child). However I need to improve it to loop continuously if the object is of another parent object. Need advice how can I improve it. Further below code is in PHP on Server Side. I am looking to take it to Client Side. Any way to do it in Angular JS. Thanks in advance to all who chose to help !

CodePudding user response：
To iterate your object recursively you need ... recursion
Create separate function with conditions inside.
- If current item belongs to page - push to array and return
- If current item belongs to object - take child element and repeat this check again.
This is pseudo code, adjust how you need it:
if($DBObj->fetchNumOfRows() >= 1){
$queryRecords = $DBObj->fetchAllRecordsArray();
$rows = $DBObj->fetchNumOfRows();
for($i = 0; $i < $rows; $i ){
recursiveAction($queryRecords[$i]);
}
}
function recursiveAction(&$item, $propertiesArray) {
switch ($item['propof']) {
case 'page':
// No need for that "if" check
$propertiesArray[$item['propofid']][] = [$item['propid'] => $item['propvalue'],'proplinkedto' => $item['proplinkedto']];
break;
case 'object':
$DBObj->querySelect(...);
$queryRecord = $DBObj->fetchNumOfRows() == 1 ? $DBObj->fetchRecordArray() : "";
if (!empty($queryRecord)) {
// Here we convert common part of "object" into recursion
recursiveAction($queryRecord);
}
break;
case 'element':
...
}
}
