Question

Array
(
[Root] => Array
(
[Parent0] => Array
(
[Child0] => Child0
)
[Parent1] => Array
(
[Child1] => Child1
)
)
)
Above tree array need to be save in mysql with parent id so results should be like below:
id parent_id name
1 0 Root
2 1 Parent0
3 2 Child0
4 1 Parent1
5 4 Child1
Any one please let me know how can i save above results in mysql using php.
Thanks in advance for quick response.

Answer 1

Try this:EDITED
$c=0;
$x;
foreach($array1 as $key=>$val){
if(is_array($val)){
echo "insert $key with parent id $c<br>";
$c++;
$x=$c;
foreach($val as $key1=>$val1){
echo " insert $key1 with parent id $x<br>";
$c++;
if(is_array($val1)){
foreach($val1 as $key2=>$val2){
echo "insert $key2 with parent id $c<br>";
$c++;
getlevel($val2,$c);
}
}/* else{
echo "else insert $key1 with parent id $c<br>";
$c++; */
}
}
}
function getlevel($value,$c1){
if(is_array($value)){
foreach($value as $keyV=>$Value){
echo " insert $keyV with parent id $c1<br>";
$c1++;
if(is_array($Value)){
getlevel($Value,$c1);
}
}
}
}
where ever i have written echo replace with your sql.Hope it helps.here $array is your array.

Below the perfect working script in any depth level tree.
$root_id;
$parent_id = 0;
foreach ( $tree_array as $root_key => $root_value ) {
$parent_id = insertRecord($root_key, $parent_id);
$root_id = $parent_id;
if ( is_array($root_value) ) {
foreach ( $root_value as $parent_key => $parent_value ) {
$parent_id = insertRecord($parent_key, $root_id);
$keep_parent_id = $parent_id;
if ( is_array($parent_value) ) {
foreach ( $parent_value as $child_key => $child_value ) {
$parent_id = insertRecord($child_key, $keep_parent_id);
getlevel($child_value, $parent_id);
}
}
}
}
}
function getlevel($sub_childs, $new_parent_id) {
$keep_new_parent_id = $new_parent_id;
if ( is_array($sub_childs) ) {
foreach ( $sub_childs as $sub_child => $sub_child_sub ) {
$new_parent_id = insertRecord($sub_child, $keep_new_parent_id);
if ( is_array($sub_child_sub) ) {
getlevel($sub_child_sub, $new_parent_id);
}
}
}
}
function insertRecord($name, $parent_id) {
$q = "insert into xtable set name = '".$name."', parent_id = '".$parent_id."'";
mysql_query($q);
$folder_id = mysql_insert_id();
return $folder_id;
}
Thanks to everyone for your efforts.

If you want to achieve parent child tree you can go for the below code with n depth
Automobile
Fuel
Gasoline
Diesel
Maintenance
Food
Fish
Pork
First create a database table named “categories” that has fields.
- category_id (PK int)
- parent_id (int)
- title (varchar)
<?php
$connect = mysql_connect("localhost", "root", "") or die ( mysql_error() );
mysql_select_db("test");
$nav_query = mysql_query("SELECT * FROM `categories` ORDER BY `category_id`") or die( mysql_error() );
$tree = ""; // Clear the directory tree
$depth = 1; // Child level depth.
$top_level_on = 1; // What top-level category are we on?
$exclude = array(); // Define the exclusion array
array_push($exclude, 0); // Put a starting value in it
while ( $nav_row = mysql_fetch_array($nav_query) )
{
$goOn = 1; // Resets variable to allow us to continue building out the tree.
for($x = 0; $x < count($exclude); $x++ ) // Check to see if the new item has been used
{
if ( $exclude[$x] == $nav_row['category_id'] )
{
$goOn = 0;
break; // Stop looking b/c we already found that it's in the exclusion list and we can't continue to process this node
}
}
if ( $goOn == 1 )
{
$tree .= $nav_row['title'] . "<br>"; // Process the main tree node
array_push($exclude, $nav_row['category_id']); // Add to the exclusion list
if ( $nav_row['category_id'] < 6 )
{ $top_level_on = $nav_row['category_id']; }
$tree .= build_child($nav_row['category_id']); // Start the recursive function of building the child tree
}
}
function build_child($oldID) // Recursive function to get all of the children...unlimited depth
{
global $exclude, $depth; // Refer to the global array defined at the top of this script
$tempTree = "";
$child_query = mysql_query("SELECT * FROM `categories` WHERE parent_id=" . $oldID);
while ( $child = mysql_fetch_array($child_query) )
{
if ( $child['category_id'] != $child['parent_id'] )
{
for ( $c=0;$c<$depth;$c++ ) // Indent over so that there is distinction between levels
{ $tempTree .= " "; }
$tempTree .= "- " . $child['title'] . "<br>";
$depth++; // Incriment depth b/c we're building this child's child tree (complicated yet???)
$tempTree .= build_child($child['category_id']); // Add to the temporary local tree
$depth--; // Decrement depth b/c we're done building the child's child tree.
array_push($exclude, $child['category_id']); // Add the item to the exclusion list
}
}
return $tempTree; // Return the entire child tree
}
echo $tree;
?>
You can copy paste the above code and you are done :)
