PHP create new arrays based on the values of another array

PHP create new arrays based on the values of another array - php

To create the data split up as you want, you can just use explode() with a space, but limit it to 2 items. The first is the type and the second is the range. Then add the items to the $optionValues array using these values.
So something like ...
if ($option['name'] == 'License') {
list($type, $range) = explode(" ", $value, 2);
$optionValues[$type][] = $range;
} else {
You can also remove the following code...
if ($option['name'] == 'License') {
$optionValues['desktop'] = ???;
$optionValues['web'] = ???;
$optionValues['app'] = ???;
}

save path and count images in mysql database

Only loop once. Only store what you need: paths and image counts.
foreach($files_dirs as $file){
if (is_file($file)) {
$d = dirname($file);
if (!isset($dirs_files[$d])) {
$dirs_files[$d] = 0;
} else {
++$dirs_files[$d];
}
}
}

Creating a multidimensional array tree from MySQL table in PHP

I'm trying to organize my mysql table into a multidimension php tree array.
For example, I'm trying to organize my products in a hierarchy for easy selection to narrow down the result the narrower they go in the result.
I am returned mysql rows like this:
Array
(
[1] => Amazon
[2] => Kindle Fire
[3] =>
[4] =>
[5] =>
[6] =>
[7] =>
[8] =>
[9] => 1
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => WiFi
[4] => 7"
[5] =>
[6] => 16GB
[7] =>
[8] =>
[9] => 2
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => WiFi
[4] => 7"
[5] =>
[6] => 32GB
[7] =>
[8] =>
[9] => 3
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => WiFi
[4] => 8.9"
[5] =>
[6] => 16GB
[7] =>
[8] =>
[9] => 4
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => WiFi
[4] => 8.9"
[5] =>
[6] => 32GB
[7] =>
[8] =>
[9] => 5
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => 4G LTE
[4] => 8.9"
[5] =>
[6] => 32GB
[7] =>
[8] =>
[9] => 6
)
Array
(
[1] => Amazon
[2] => Kindle Fire HD
[3] => 4G LTE
[4] => 8.9"
[5] =>
[6] => 64GB
[7] =>
[8] =>
[9] => 7
)
Array
(
[1] => Amazon
[2] => Kindle Fire HDX
[3] => Wifi
[4] => 7"
[5] =>
[6] => 16GB
[7] =>
[8] =>
[9] => 8
)
Array
(
[1] => Amazon
[2] => Kindle Fire HDX
[3] => Wifi
[4] => 7"
[5] =>
[6] => 32GB
[7] =>
[8] =>
[9] => 9
)
Array
(
[1] => Amazon
[2] => Kindle Fire HDX
[3] => Wifi
[4] => 7"
[5] =>
[6] => 64GB
[7] =>
[8] =>
[9] => 10
)
...etc
Note the last array value is the Product ID.
And I'm looking for help writing a recursive function that will result in an array that looks like:
Array(
'Amazon' => Array(
'Kindle Fire' => 1,
'Kindle Fire HD' => Array(
'WiFi' => Array(
'7"' => Array(
'16GB' => 2,
'32GB' => 3
)
'8.9"' => Array(
'16GB' => 4,
'32GB' => 5
)
)
)
)
)
I've tried something like:
while($row = mysqli_fetch_row($res)) {
$id = $row[0];
unset($row[0]);
unset($row[count($row)]);
$row[] = $id; // Moves id to last array value
for($i = 1; $i < count($row); $i++) {
if($i == 1) {
if(!array_key_exists($row[$i], $data)) {
// Insert key
$data[$row[$i]] = array();
}
}
else {
$level = $data[$row[$i-1]];
if(array_key_exists($row[$i], $level)) {
// Key exists
}
else {
// Insert key
}
}
}
}

I think your code has a good intention: using $level to hold the current depth. But at the moment this won't work, because you are copying via $level = $data[$row[$i-1]]; - instead you need to refer to it, e.g. with $level =& $data[$row[$i-1]];.
$result = array();
while ($row = mysqli_fetch_row($res)) [
$id = array_shift($row);
if (!isset($maxIterator))
$maxIterator = count($row)-1;
$current =& $result;
for ($i=0; $i<$maxIterator; $i++) {
if (empty($row[$i]))
break;
if (!array_key_exists($row[$i], $current))
$current[ $row[$i] ] = array();
$current =& $current[ $row[$i] ];
}
//for properly ended and wasn't broken out of sooner
if ($i == $maxIterator) {
if (!array_key_exists($row[$i], $current))
$current[ $row[$i] ] = 1;
else
$current[ $row[$i] ]++;
}
}
array_shift basically does, what you needed two lines for: get the first element of an array and then remove it. Then I save the result of the count in a variable, so it doesn't need to be recalculated in every iteration of the for AND while.
Also I would suggest setting $maxIterator manually. With the shown result a good default would be 5. This way all values before the 5th. will be used for nesting and the 5th itself will be used to count (in your example this is storage size).
As the for will execute $i++ after the last iteration (and then it fails the condition and hence the loop breaks), it can be used for the counting.
Personally I would overthink what exactly you are doing and maybe use a specifc structure for that. However, this code should give you a good impression how it can be solved using references.

get specific values of array not showing

This is what my array looks like :
Array (
[0] => SimpleXMLElement Object (
[key] => Array (
[0] => Track ID
[1] => Name
[2] => Artist
[3] => Album Artist
[4] => Composer
[5] => Album
[6] => Genre
[7] => Kind
[8] => Size
[9] => Total Time
[10] => Disc Number
[11] => Disc Count
[12] => Track Number
[13] => Year
[14] => Date Modified
[15] => Date Added
[16] => Bit Rate
[17] => Sample Rate
[18] => Play Count
[19] => Play Date
[20] => Play Date UTC
[21] => Artwork Count
[22] => Persistent ID
[23] => Track Type
[24] => Location
[25] => File Folder Count
[26] => Library Folder Count )
[integer] => Array (
[0] => 2056
[1] => 3732918
[2] => 230661
[3] => 1
[4] => 1
[5] => 1
[6] => 1993
[7] => 128
[8] => 44100
[9] => 3
[10] => 3439412487
[11] => 1
[12] => 5
[13] => 1 )
[string] => Array (
[0] => Eye of the Tiger
[1] => Survivor
[2] => Survivor
[3] => Frankie Sullivan/Jim Peterik
[4] => Greatest Hits
[5] => Rock
[6] => MPEG audio file
[7] => 772F0F53F195E705
[8] => File
[9] => file://localhost/Users/cameron/Music/iTunes/iTunes%20Media/Music/Survivor/Greatest%20Hits/01%20Eye%20of%20the%20Tiger.mp3 )
[date] => Array (
[0] => 2012-08-27T17:01:00Z
[1] => 2012-08-27T17:01:03Z
[2] => 2012-12-27T07:21:27Z ) )
that's 1 result, there is about 50 of them repeated.
I am trying to select the artist value in this case : Frankie Sullivan/Jim Peterik
please note: there is about 50 other results that come after this first one, so I would like to do a foreach to display all results.
any suggestions? I am stuck.this is the code I used to get these results:
$xml = simplexml_load_file('Library.xml');
$xmlx = $xml->dict->dict->dict->key;
$artist = $xmlx->xpath("//dict[key='Artist']");
echo "<pre>" . print_r($artist, true) . "</pre>";

It seems that you have an array of SimpleXMLElement,
so you can iterate over your array and use the SimpleXMLElement facilities.
Try:
foreach($yourArray as $simpleXmlElement)
{
// Retrieve the name
echo $simpleXmlElement->string[3];
}
Take a look at the documentation for more question: SimpleXMLElement
For your specific problem, assuming the key and string are synchronized, you can try:
// Loop on your array of SimpleXMLElement
foreach($yourArray as $simpleXmlElement)
{
// Initialize the position and found value
$position = 0;
$found = false;
// Loop on the sub array 'key' and search the 'Artist Album' position
foreach($simpleXmlElement->key as $index => $value)
{
if ($value == "Album Artist")
{
$found = true;
break;
}
// Not found, increment position
$position++;
}
// Retrieve the name if found the artist album key
if ($found)
echo $simpleXmlElement->string[$position];
}
As
[3] => Album Artist
will give the position 3
Then, when retrieving the string value, it will return Frankie Sullivan/Jim Peterik
