Array returning images from previous iteration - php

For some reach my array returns the data numerous times, for different arrays after filtering via a foreach in the second example the post only contains 1 unique link so the rest shouldn't exist at all, it should print simply the data from image_1 here's the PHP code.
$imagecounter = 1;
foreach ($html2->find('.post img') as $source) {
$link = $source->src;
if (strpos($link, 'https://www.example.com/wp-content/uploads/') !== false) {
$data['image_'.$imagecounter++.''] = $link;
}
}
And here's the array.

Start with an empty $data array.
$data = [];
$imagecounter = 1;
foreach ($html2->find('.post img') as $source) {
$link = $source->src;
if (strpos($link, 'https://www.example.com/wp-content/uploads/') !== false) {
$data['image_'.$imagecounter++.''] = $link;
}
}
If you need to store multiple sets of $data, then you can store each new $data batch in a parent array.
foreach ($htmls as $html2) {
$data = [];
$imagecounter = 1;
foreach ($html2->find('.post img') as $source) {
$link = $source->src;
if (strpos($link, 'https://www.example.com/wp-content/uploads/') !== false) {
$data['image_'.$imagecounter++.''] = $link;
}
}
$result[] = $data;
}

Better way to dynamically access values in nested array

I need a way to dynamically access values in a nested array using an index map. What i want to achieve is looping over an array with data and extract some values that can be in any level of the nesting and save it to a bi-dimensional array.
So far I've come up with the following code, which works quite well, but I was wondering if there is a more efficient way to do this.
<?php
// Sample data
$array = array();
$array[0]['code'] = "ABC123";
$array[0]['ship'] = array("name" => "Fortune", "code" => 'FA');
$array[0]['departure'] = array("port" => "Amsterdam", "code" => "AMS");
$array[0]['document'] = array("type" => "Passport", "data" => array("valid" => '2022-03-18', 'number' => 'AX123456') );
$array[1]['code'] = "QWERT67";
$array[1]['ship'] = array("name" => "Dream", "code" => 'DR');
$array[1]['departure'] = array("port" => "Barcelona", "code" => "BRC");
$array[1]['document'] = array("type" => "Passport", "data" => array("valid" => '2024-12-09', 'number' => 'DF908978') );
// map of indexes of $array I need in my final result array. The levels of the nested indexes is subdivided by ":"
$map = array("code", "ship:name", "departure:port", "document:type", "document:data:number");
$result = array();
// loop array for rows of data
foreach($array as $i => $row){
// loop map for indexes
foreach($map as $index){
// extract specific nested values from $row and save them in 2-dim array $result
$result[$i][$index] = xpath_array($index, $row);
}
}
// print out result
print_r($result);
// takes path to value in $array and returns given value
function xpath_array($xpath, $array){
$tmp = array();
// path is subdivded by ":"
$elems = explode(":", $xpath);
foreach($elems as $i => $elem){
// if first (or ony) iteration take root value from array and put it in $tmp
if($i == 0){
$tmp = $array[$elem];
}else{
// other iterations (if any) dig in deeper into the nested array until last item is reached
$tmp = $tmp[$elem];
}
}
// return found item (can be value or array)
return $tmp;
}
Any suggestion?
This was quite tricky for me, i used Recursive function, first we normalize array keys to obtain key as you want like this document:type, then we normalize array to obtain all at same level :
/**
* #param array $array
* #param string|null $key
*
* #return array
*/
function normalizeKey(array $array, ?string $key = ''): array
{
$result = [];
foreach ($array as $k => $v) {
$index = !empty($key) && !\is_numeric($key) ? $key.':'.$k : $k;
if (true === \is_array($v)) {
$result[$k] = normalizeKey($v, $index);
continue;
}
$result[$index] = $v;
}
return $result;
}
/**
* #param array $item
* #param int $level
*
* #return array
*/
function normalizeStructure(array $item, int $level = 0): array
{
foreach ($item as $k => $v) {
$level = isset($v['code']) ? 0 : $level;
if (true === \is_array($v) && 0 === $level) {
$item[$k] = normalizeStructure($v, ++$level);
continue;
}
if (true === \is_array($v) && 0 < $level) {
$item = \array_merge($item, normalizeStructure($v, ++$level));
unset($item[$k]);
continue;
}
}
return $item;
}
$data = normalizeStructure(normalizeKey($array));
I edited your data set to add more nests:
// Sample data
$array = array();
$array[0]['code'] = "ABC123";
$array[0]['ship'] = array("name" => "Fortune", "code" => 'FA');
$array[0]['departure'] = array("port" => "Amsterdam", "code" => "AMS");
$array[0]['document'] = array("type" => "Passport", "data" => array("valid" => '2022-03-18', 'number' => 'AX123456'));
$array[1]['code'] = "QWERT67";
$array[1]['ship'] = array("name" => "Dream", "code" => 'DR');
$array[1]['departure'] = array("port" => "Barcelona", "code" => "BRC");
$array[1]['document'] = array("type" => "Passport", "data" => array("valid" => '2024-12-09', 'number' => 'DF908978', 'check' => ['number' => '998', 'code' => 'itsWell', 'inception' => ['border' => 'finalInception']]));
With these data, you should finally receive this result:
/*
Array
(
[0] => Array
(
[code] => ABC123
[ship:name] => Fortune
[ship:code] => FA
[departure:port] => Amsterdam
[departure:code] => AMS
[document:type] => Passport
[document:data:valid] => 2022-03-18
[document:data:number] => AX123456
)
[1] => Array
(
[code] => QWERT67
[ship:name] => Dream
[ship:code] => DR
[departure:port] => Barcelona
[departure:code] => BRC
[document:type] => Passport
[document:data:valid] => 2024-12-09
[document:data:number] => DF908978
[document:data:check:number] => 998
[document:data:check:code] => itsWell
[document:data:check:inception:border] => finalInception
)
)
*/
Recursivity seems to be like Inception, everything is nested and you can lose your mind in 😆, mine was already lost in.

How to show duplicate data in multidimensional array using PHP

I am using Spout Excel reader to read Excel files from php code and saving into a multidimensional array in PHP variable,Array looks like this
$array = [
[
'id[0]' => 'BX-78',
'Name[0]' => 'XXX',
'Address[0]' => 'YUUSATD'
],
[
'id[1]' => 'BX-79',
'Name[1]' => 'YYY',
'Address[1]' => 'DHJSHDJGY'
],
[
'id[2]' => 'BX-80',
'Name[2]' => 'ZZZ',
'Address[2]' => 'DDSDSDA'
]
[
'id[3]' => 'BX-78',
'Name[3]' => 'AAA',
'Address[3]' => 'FSDSDS'
][
'id[4]' => 'BX-81',
'Name[4]' => 'XXX',
'Address[4]' => 'DSDSDSD'
]];
Now i want to show duplicate data from above array using two keys ['id'] and ['name'] if id repeats show as duplicate data,
If name repeats show that row as duplicate data if both are duplicate show as again duplicate row
Otherwise it is unique row.
I have tried using multidimensional array sorting but it is using only one key to match data in rows.
foreach ($arrExcelData as $v) {
if (isset($arrExcelData[$v[0]])) {
// found duplicate
continue;
}
// remember unique item
$arrExcelData3[$v[0]] = $v;
}
// if you need a zero-based array, otheriwse work with $_data
$arrExcelData2 = array_values($arrExcelData3);
Edited : Expected Output Result :
Matching Rows:
Id Name Address
-------------------------
BX-78 XXX YUUSATD
BX-78 AAA DDSDSDA
BX-81 XXX DSDSDSD`
If you want to list the duplicate values, I think the address of the second match should be FSDSDS as there is not item with name AAA and value DDSDSDA:
BX-78 AAA FSDSDS
If that is the case, what you could do is to first use a double foreach to mark the arrays that contain a duplicate id or name by for example adding a property named id and name except when the array is itself in the second loop.
After this loop, you can tell which arrays are the duplicate ones. Instead of using a corresponding index 0 as in id[0], I have used reset and next so it is not tied to these indexes.
To get the filtered result you could use array_reduce to check for the array keys and unset them.
For example:
foreach ($array as $index => $a) {
foreach ($array as $v) {
if ($v === $a) continue;
if (reset($v) === reset($a)) $array[$index]["id"] = "duplicate";
if (next($v) === next($a)) $array[$index]["name"] = "duplicate";
}
}
$array = array_reduce($array, function($carry, $item) {
if (array_key_exists("id", $item) || array_key_exists("name", $item)) {
unset($item["id"], $item["name"]);
$carry[] = $item;
}
return $carry;
}, []);
print_r($array);
Result
Array
(
[0] => Array
(
[id[0]] => BX-78
[Name[0]] => XXX
[Address[0]] => YUUSATD
)
[1] => Array
(
[id[3]] => BX-78
[Name[3]] => AAA
[Address[3]] => FSDSDS
)
[2] => Array
(
[id[4]] => BX-81
[Name[4]] => XXX
[Address[4]] => DSDSDSD
)
)
See a php demo
I've this very pragmatic approach:
$spout_output = [
[
'id[0]' => 'BX-78',
'Name[0]' => 'XXX',
'Address[0]' => 'YUUSATD'
],
[
'id[1]' => 'BX-79',
'Name[1]' => 'YYY',
'Address[1]' => 'DHJSHDJGY'
],
[
'id[2]' => 'BX-80',
'Name[2]' => 'ZZZ',
'Address[2]' => 'DDSDSDA'
],
[
'id[3]' => 'BX-78',
'Name[3]' => 'AAA',
'Address[3]' => 'FSDSDS'
],
[
'id[4]' => 'BX-81',
'Name[4]' => 'XXX',
'Address[4]' => 'DSDSDSD'
]];
// store id to row, and name to row mappings.
// id and name will be keys, value will be an array of indexes of the array $spout_output
$id_to_rows = array();
$name_to_rows = array();
$duplicate_ids = array();
$duplicate_names = array();
foreach($spout_output as $row => $data)
{
$key_id = 'id['.$row.']';
$key_name = 'Name['.$row.']';
if(!isset($data[$key_id]))
continue;
$value_id = $data[$key_id];
$value_name = $data[$key_name];
if(!isset($id_to_rows[$value_id]))
{
$id_to_rows[$value_id] = array();
}
else
{
if(!isset($duplicate_ids[$value_id]))
{
$duplicate_ids[$value_id] = $id_to_rows[$value_id];
}
$duplicate_ids[$value_id][] = $row;
}
if(!isset($name_to_rows[$value_name]))
{
$name_to_rows[$value_name] = array();
}
else
{
if(!isset($duplicate_names[$value_name]))
{
$duplicate_names[$value_name] = $name_to_rows[$value_name];
}
$duplicate_names[$value_name][] = $row;
}
$id_to_rows[$value_id][] = $row;
$name_to_rows[$value_name][] = $row;
}
echo 'Duplicates:';
echo '<br>';
$shown_rows = array();
foreach($duplicate_ids as $id => $rows)
{
foreach($rows as $nr)
{
echo $id . '|' . $spout_output[$nr]['Name['.$nr.']'] . '|' . $spout_output[$nr]['Address['.$nr.']'];
echo '<br>';
$shown_rows[] = $nr;
}
}
foreach($duplicate_names as $name => $rows)
{
foreach($rows as $nr)
{
// if already shown above, skip this row
if(in_array($nr, $shown_rows))
continue;
echo $spout_output[$nr]['id['.$nr.']'] . '|' . $spout_output[$nr]['Name['.$nr.']'] . '|' . $spout_output[$nr]['Address['.$nr.']'];
echo '<br>';
$shown_rows[] = $nr;
}
}
Outputs:
Duplicates:
BX-78|XXX|YUUSATD
BX-78|AAA|FSDSDS
BX-81|XXX|DSDSDSD
I think your 'wanted output' contains an error in the address?
Anyway, with my code above I think you'll have enough mapped data to produce the output you want.
You could do something like this:
$dupes = [];
$current = [];
foreach ($array as $index => $entry) {
$idKey = "id[$index]";
$nameKey = "Name[$index]";
if (array_key_exists($entry[$idKey], $current)) {
$dupes[] = [$entry, $current[$entry[$idKey]]];
}
elseif (array_key_exists($entry[$nameKey], $current)) {
$dupes[] = [$entry, $current[$entry[$nameKey]]];
}
else {
$current[$entry[$idKey]] = $current[$entry[$nameKey]] = $entry;
}
}
print_r($dupes);
Which results in an array containing each set of duplicates (array of arrays):
Array
(
[0] => Array
(
[0] => Array
(
[id[3]] => BX-78
[Name[3]] => AAA
[Address[3]] => FSDSDS
)
[1] => Array
(
[id[0]] => BX-78
[Name[0]] => XXX
[Address[0]] => YUUSATD
)
)
[1] => Array
(
[0] => Array
(
[id[4]] => BX-81
[Name[4]] => XXX
[Address[4]] => DSDSDSD
)
[1] => Array
(
[id[0]] => BX-78
[Name[0]] => XXX
[Address[0]] => YUUSATD
)
)
)
Demo here: https://3v4l.org/JAtNU
In case someone of you are searching unique values by key.
function unique_multidim_array($array, $key) {
$temp_array = array();
$i = 0;
$key_array = array();
foreach($array as $val) {
if (!in_array($val[$key], $key_array)) {
$key_array[$i] = $val[$key];
$temp_array[$i] = $val;
}
$i++;
}
return $temp_array;
}
This function just takes multidimensional array and key value of field you need.
Then takes value of given array one by one (smaller arrays).
Then traverses given array and looking if taken key-value pair matches with given key.
After that if taken key-value pair matches with given key function just inserts smaller array in temporary array (array with unique values).
Don't forget to increment indexes of arrays ($i).
Then return array you got (with unique values) after function ends work.

Foreach array to update table of database use those element of array

How to get the first value of element of array in php.
My story board is like this:
I have an array like this:
(
[0] => Array
(
[ID] => 68
[MATERIAL] => I have
[AC] => Try
)
[1] => Array
(
[ID] => 69
[MATERIAL] => It
[AC] => No Surrender
)
)
I want to update some record on my database like this,
foreach element of array,
UPDATE MY TABEL SET MATERIAL = [MATERIAL], AC = [AC] where id= [id]
this is the model named m_admin :
public function update_eir_to_cost($id, $material, $ac) {
$data = array(
"MATERIAL" => $material,
"AC" => $ac);
$this->db->trans_start();
$this->db->where($id);
$this->db->update('tb_repair_detail', $data);
$this->db->trans_complete();
if ($this->db->trans_status() === FALSE) {
// generate an error... or use the log_message() function to log your error
echo "Error Updating";
} else {
echo "Alhamdulillah";
}
}
This is the controller :
public function update_json_detail() {
$post_data = $this->input->post("POST_ARRAY");
$execute = array();
foreach ($post_data as $data) {
$execute[] = array(
'ID'=> $data['0'],
'MATERIAL' => $data['7'],
'AC' => $data['8']
);
}
echo "<pre>";
print_r($execute); // return an array like above.
/*forech element
update table using model
*/
}
This will solve your problem:
public function update_json_detail() {
$post_data = $this->input->post("POST_ARRAY");
$execute = array();
foreach ($post_data as $data) {
$execute[] = array(
'ID'=> $data['0'],
'MATERIAL' => $data['7'],
'AC' => $data['8']
);
}
echo "<pre>";
print_r($execute); // return an array like above.
$this->load->model('m_admin');
foreach ($execute as $row) {
$this->m_admin->update_eir_to_cost($row['ID'], $row['MATERIAL'], $row['AC']);
}
}

Compare two arrays and append last values if they are the same else value zero

I have two string values namely $late_array and $wrong_array. The values are comma delimited.
What I would like to do is compare the two arrays and if the first two elements are the same add the value to the end else make it zero. The arrays I have:
$late_array = array(
[0] => 140610d,Richard,12
[1] => 140610a,Dave,22
[2] => 140610n,Noddy,121
[3] => 140610a,Nick,15
)
$wrong_array = array(
[0] => 140610d,Richard,2
[1] => 140610d,Mary,60
[2] => 140610a,Dave,11
[3] => 140610n,Noddy,90
)
The end result should be:
$combined_array = array(
[0] => 140610d,Richard,12,2
[1] => 140610d,Mary,0,60
[2] => 140610a,Dave,22,11
[3] => 140610a,Nick,15,0
[4] => 140610n,Noddy,121,90
)
I have so far formed a foreach and used the '===' operators to check if the date and name match then output as I want but I have not been able to get it to work if the name is not present in one array but another to make the value zero.
EDIT: Just to clear it up, hopefully. If the value is present in both arrays then the date,name,late value,wrong value should show. But if the value is present in late only then the value for wrong should be 0, same visa versa. Added "Nick" to try and explain a bit better.
This is what I did to solve the problem so far:
$wrong_val = array();
foreach($out as $wrong_value) {
$wrong_tosearch[] = substr($wrong_value,0,strrpos($wrong_value,","));
$w_id = substr($wrong_value,0,strrpos($wrong_value,","));
$wrong_val[$w_id] = substr($wrong_value,strrpos($wrong_value,",")+1,strlen($wrong_value));
}
foreach($sql_late_array as $late_value) {
$late_tosearch[] = substr($late_value,0,strrpos($late_value,","));
$l_id = substr($late_value,0,strrpos($late_value,","));
$late_val[$l_id] = substr($late_value,strrpos($late_value,",")+1,strlen($late_value));
}
$merge = array_merge($wrong_tosearch,$late_tosearch);
$sort = array_values(array_unique($merge));
$combined_array = array();
foreach ($sort as $search_val) {
if (array_key_exists($search_val,$wrong_val) !== FALSE) {
foreach ($wrong_val as $w_key=>$w_val) {
$combined_array[$w_key]['late'] = "0";
$combined_array[$w_key]['wrong'] = $w_val;
}
}
if (array_key_exists($search_val,$late_val) !== FALSE) {
foreach ($late_val as $l_key=>$l_val) {
$combined_array[$l_key]['wrong'] = "0";
$combined_array[$l_key]['late'] = $l_val;
}
}
}
print_r($combined_array);
Check if below code solves your problem.
$late_array = array(
"0" => "140610d,Richard,12",
"1" => "140610a,Dave,22",
"2" => "140610n,Noddy,121"
);
$wrong_array = array(
"0" => "140610d,Richard,2",
"1" => "140610d,Mary,60",
"2" => "140610a,Dave,11",
"3" => "140610n,Noddy,90"
);
foreach($wrong_array as $wv)
{
$tosearch = substr($wv,0,strrpos($wv,",")-1);
$valtoadd = substr($wv,strrpos($wv,",")+1,strlen($wv));
$added=false;
foreach($late_array as $lv)
{
if(strstr($lv, $tosearch) !== false)
{
$combined_array[] = $lv.",".$valtoadd;
$added=true;
break;
}
}
if(!$added)
$combined_array[] = $tosearch.",0,".$valtoadd;
}
$tcombined_array = $combined_array;
foreach($late_array as $wv)
{
$added = false;
foreach($tcombined_array as $cv)
if(strstr($cv,$wv))
$added = true;
if(!$added) $combined_array[] = $wv.",0";
}
print_r($combined_array);
May be big but works
<?php
$late_array = array(
0 => "140610d,Richard,12",
1 => "140610a,Dave,22",
2 => "140610n,Noddy,121",

);
$pattern = "/[0-9]*[a-zA-Z]*,[0-9]*[a-zA-Z]*,/";
$combined_array = $late_array;
foreach($wrong_array as $wrong_index => $wrong_value){

preg_match_all($pattern, $late_value, $late_matches);
preg_match_all($pattern, $wrong_value, $wrong_matches);

PHP - Create Hierarchal Array

I'm not even sure how to begin wording this question, but basically, I have an array, that looks like this:
Array
(
[0] => /
[1] => /404/
[2] => /abstracts/
[3] => /abstracts/edit/
[4] => /abstracts/review/
[5] => /abstracts/view/
[6] => /admin/
[7] => /admin/ads/
[8] => /admin/ads/clickcounter/
[9] => /admin/ads/delete/
[10] => /admin/ads/edit/
[11] => /admin/ads/list/
[12] => /admin/ads/new/
[13] => /admin/ads/sponsordelete/
[14] => /admin/ads/sponsoredit/
[15] => /admin/ads/sponsornew/
[16] => /admin/ads/stats/
[17] => /admin/boilerplates/
[18] => /admin/boilerplates/deleteboiler/
[19] => /admin/boilerplates/editboiler/
[20] => /admin/boilerplates/newboilerplate/
[21] => /admin/calendar/event/add/
[22] => /admin/calendar/event/copy/
)
And I need to 'reduce' / 'process' it into an array that looks like this:
Array
(
[''] => Array()
['404'] => Array()
['abstracts'] => Array
(
[''] => Array()
['edit'] => Array()
['review'] => Array()
['view'] => Array()
)
['admin'] => Array
(
['ads'] => Array
(
[''] => Array()
['clickcounter'] => Array()
['delete'] =>Array()
['edit'] => Array()
)
)
.....
.....
)
That, if manually initialized would look something like this:
$urlTree = array( '' => array(),
'404' => array(),
'abstracts'=> array( '' => array(),
'edit' => array(),
'review'=> array(),
'view' => array() ),
'admin' => array( 'ads'=> array( '' => array(),
'clickcounter'=> array(),
'delete' => array(),
'edit' => array() ) )
);
I usually stray away from asking straight up for a chunk of code on SO, but does anyone perhaps have any advice / code that can traverse my array and convert it to a hierarchy?
EDIT: Here is the bit I have right now, which, I know is pitifully small, I'm just blanking out today it seems.
function loadUrlData()
{
// hold the raw data, /blah/blah/
$urlData = array();
$res = sql::query( "SELECT DISTINCT(`url`) FROM `pages` ORDER BY `url` ASC" );
while( $row = sql::getarray( $res ) )
{
$urlData[] = explode( '/', substr( $row['url'], 1, -1 ) );
}
// populated, eventually, with the parent > child data
$treeData = array();
// a url
foreach( $urlData as $k=> $v )
{
// the url pieces
foreach( $v as $k2=> $v2 )
{
}
}
// $treeData eventually
return $urlData;
}
Looks rather easy. You want to loop through all lines (foreach), split them into parts (explode), loop through them (foreach) and categorize them.
Since you don't like asking for a chunk of code, I won't provide any.
Update
A very nice way to solve this is to reference the $urlTree (use &), loop through every part of the URL and keep updating a variable like $currentPosition to the current part in the URL tree. Because you use &, you can simply edit the array directly while still using a simple variable.
Update 2
This might work:
// a url
foreach( $urlData as $k=> $v )
{
$currentSection = &$treeData;
// the url pieces
foreach( $v as $k2=> $v2 )
{
if (!isset($currentSection[$v2])) {
$currentSection[$v2] = array();
}
$currentSection = &$currentSection[$v2];
}
}
I know you didn't ask for a chunk of code, but I'd just call this a petit serving:
$map = array();
foreach($urls as $url) {
$folders = explode('/', trim($url, '/'));
applyChain($map, $folders, array());
}
function applyChain(&$arr, $indexes, $value) { //Here's your recursion
if(!is_array($indexes)) {
return;
}
if(count($indexes) == 0) {
$arr = $value;
} else {
applyChain($arr[array_shift($indexes)], $indexes, $value);
}
}
It's fairly simple. We separate each url into its folders (removing trailing and leading slashes) and then work our way down the array chain until we reach the folder mentioned in the URL. Then we place a new empty array there and continue to the next URL.
My version:
$paths = array(
0 => '/',
1 => '/404/',
2 => '/abstracts/',
3 => '/abstracts/edit/',
4 => '/abstracts/review/',
5 => '/abstracts/view/',
6 => '/admin/',
7 => '/admin/ads/',
// ....
);
$tree = array();
foreach($paths as $path){
$tmp = &$tree;
$pathParts = explode('/', rtrim($path, '/'));
foreach($pathParts as $pathPart){
if(!array_key_exists($pathPart, $tmp)){
$tmp[$pathPart] = array();
}
$tmp = &$tmp[$pathPart];
}
}
echo json_encode($tree, JSON_PRETTY_PRINT);

}
}
return $original;

$old_array = array("/", "/404/", "/abstracts/", "/abstracts/edit/", "/abstracts/review/", "/rrl/");
$new_array = array();
foreach($old_array as $woot) {
$segments = explode('/', $woot);
$current = &$new_array;
for($i=1; $i<sizeof($segments); $i++) {
if(!isset($current[$segments[$i]])){
$current[$segments[$i]] = array();
}
$current = &$current[$segments[$i]];
}
}
print_r($new_array);

You might consider converting your text to a JSON string, then using json_decode() to generate the structure.
