PHP: Sorting MySQL result to multi-dimensional array - php

Now I'm tryin' to sort MySQL result to multi-dimensional array by type line in SQL
so, that's my code:
function getTableValues($table_name)
{
// $link = connect_db();
$front_end_query = "SELECT * FROM `".$table_name."` WHERE `type` = 'front_end'";
$front_end_query_result = mysql_query($front_end_query);
$cur_row = 0;
/*while ($line = mysql_fetch_assoc($queryresult))
{
$values = $line;
$cur_row++;
}*/
$front_end = mysql_fetch_assoc($front_end_query_result);
$i=0;
while ($line = mysql_fetch_assoc($front_end_query_result)){
#if ($line['type'] === 'front_end'){
# $line[$line['type']][$line['name']] = $line['value'];
# $line[$line['type']][$line['name']]['desc'] = $line['description'];
# $line[$line['type']][$line['name']]['visible_name'] = $line['visible_name'];
# $line[$line['type']][$line['name']]['write_roles'] = $line['write_roles'];
# $line[$line['type']][$line['name']]['read_roles'] = $line['read_roles'];
#}
$values['front_end'][$line['name']] = $line;
$i++;
}
return $values;
}
And my MySQL table:
id type write_roles read_roles name value description visible_name
1 front_end 0 any title sometitle exampletitle Title
2 front_end 0 any description somedesc example Description
And that's what I want to get:
$config[(someType)][(SomeName)] = (value of line)
$config[(someType)][(SomeName)][(SomeOption)] = (value of option)
E.g.: $config['front_end']['title']['description'] that returns exampletitle
How I can do that?
UPD0: so I tried to echo my array with foreach, and it's returned just one row from my DB.
What I doing wrong?

$values = array(); //base array
while ($line = mysql_fetch_assoc($front_end_query_result)){ //fetch the rows
//in the base array create a new array under 'name'
$values[$line['name']] = array();
//for each item in the result set, add it to the new array
foreach ($line as $key => $value) {
$values[$line['name']][$key] = $value;
}
}

PHP combine matching rows from associative arrays from sql and display results in html

I have 2 results set
$result_a = #pg_query($rquery_a);
$result_b = #pg_query($rquery_b);
I have 2 arrays to host and display the data on an html page:
$datas_a = array();
$datas_b = array();
$datas_a gets this data:
$i=0;
while ($row = #pg_fetch_assoc($result_a)){
$datas_a[$i] = array('s1' => $row['salle'],
'duree_occu' => $row['duree_resa']);
$i++;
}
and $datas_b gets this data:
$i=0;
while ($row = #pg_fetch_assoc($result_b)){
$datas_b[$i] = array('s1' => $row['salle'],
'duree_cours' => $row['duree_cours']);
$i++;
}
From these 2 existing arrays with same number of rows and same keys, I would like 3 columns, 1 column is the same for both arrays ($datas_a and $datas_b), the second column is from $datas_a and the third column is from $datas_b
It currently looks like this for $datas_a
$datas_a
It currently looks like this for $datas_b
$datas_b
It should look like this
merging columns
Now, I have used
$dataComb = array_merge($datas_a, $datas_b);
but it puts one array on top of the other while I would like to just add a column
try
$i=0;
foreach ($datas_a as $data) {
$dataComb[$i]["s1"] = $data["s1"];
$dataComb[$i]["duree_resa"] = $data["duree_resa"];
$i++;
}
$i=0;
foreach ($datas_b as $data) {
$dataComb[$i]["duree_cours"] = $data["duree_cours"];
$i++;
}
Edit - 2021-08-20
Or for something more robust given it's a basic way I only know to do this
$datas_a = array(); // associative array
$datas_b = array();
$dataComb = []; // indexed array
$i=0;
while ($row = #pg_fetch_assoc($result_a)){
$datas_a[$i] = array('s1' => $row['salle'],
'duree_resa' => $row['duree_resa']);
$i++;
}
$i=0;
while ($row = #pg_fetch_assoc($result_b)){
$datas_b[$i] = array('s1' => $row['salle'],
'duree_cours' => $row['duree_cours']);
$i++;
}
$i=0;
if($a>=$b){
foreach($datas_a as $dataa) {
$dataTmp[$i][0] = $dataa["s1"];
$dataTmp[$i][1] = $dataa["duree_resa"];
foreach($datas_b as $datab) {
if($dataa["s1"] == $datab["s1"] ){
$dataTmp[$i][2] = $datab["duree_cours"];
}
}
$i++;
}
}
elseif($a<$b){
foreach($datas_b as $datab) {
$dataTmp[$i][0] = $datab["s1"];
$dataTmp[$i][1] = $datab["duree_resa"];
foreach($datas_a as $dataa) {
if($datab["s1"] == $dataa["s1"] ){
$dataTmp[$i][2] = $dataa["duree_cours"];
}
}
$i++;
}
}
$nb_lig = $a>=$b ? $a : $b;
for ($row=0; $row<=$nb_lig; $row++) {
$dataComb[$row]["s1"] = $dataTmp[$row][0];
$dataComb[$row]["duree_resa"] = $dataTmp[$row][1];
$dataComb[$row]["duree_cours"] = $dataTmp[$row][2];
}
And there is $dataComb as an associative array that combines the data from previous arrays with matching records
foreach ($dataComb as $data){
echo '<tr>';
echo '<td>'.$data["s1"].'</td>';
echo '<td>'.$data["duree_resa"].'</td>';
echo '<td>'.$data["duree_cours"].'</td>';
echo '</tr>';
}

I want to match my array value to a column value from a table in php

date_default_timezone_set('Asia/Kolkata');
header('Access-Control-Allow-Origin: *');
include_once('conn.php');
$data2 = array();
$content = trim(file_get_contents("php://input"));
$data = json_decode($content);
$couplenumber = $data->contact_number;
$sql = "SELECT * from `users_table` where `phone` IN '$couplenumber'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
array_push($data2, $row);
}
echo json_encode($data2);
} else {
echo 0;
}
$conn->close();
$couplenumber is an array it has multiple contact numbers. I want to match my array value to the table column named the phone. The phone has a string value that means a single contact. How I can get data after match phone value to multiple contacts of $couplenumber value?
It will be better, if you show us your arrays content. But, if you have some things like one objects array and one array with ids only, let's try it:
//Arrays are like :
$tab1 = [3,4];
//Considering Object is a class which receive id in constrictor and has et getId method.
$obj1 = new Object(1);
$obj2 = new Object(2);
$items = [$obj1, $obj2];
$tab2 = [];
foreach ($items as $item) {
$tab2[] = $item->getId();
}
$diff = array_merge(array_diff($tab1, $tab2), array_diff($tab2, $tab1));
// True there are same, false there differents.
var_dump( empty($diff) && (count($tab1) === count($tab2)) );

How to create custom CSV files using PHP?

In the $csv_array_attributes[0] represents every column for my csv file. sku is the product id. In $csv_array_attributes[0] represents all of the product ids for my csv(which is the rows value form column sku). In the query below I extract all of the products ids, attributes names and attributes values. My problem is that I have to compute my $csv array in order to assign for each attribute name(columns) the attribute values. In $final_string somehow I want to memorize all of the attributes values for a products (see the commented part). Thx in advance for the help. Im really stuck with this :(
$csv_array_attributes[0] = "sku%%".$header;
//GETTING ATTRIBUTES VALUES
$i = 1;
foreach($xml->children() as $content){
$id_produs = $content->ProductCode;
$csv_array_attributes[$i] = $id_produs;
$i++;
}
$select = mysql_query("SELECT id_prod.id_produs, GROUP_CONCAT('^^',nume_attr) AS nume_at, GROUP_CONCAT('^^',val_attr) AS val_at FROM attributes
INNER JOIN id_prod
ON id_prod.id_id_produs = attributes.id_produs
GROUP BY id_prod.id_produs");
$i = 0; $id_prod = array();
while ($row = mysql_fetch_array($select)){
$id_produs = $row['id_produs'];
$nume_attr = explode(",^^",substr($row['nume_at'],2));
$val_attr = explode(",^^",substr($row['val_attr'],2));
$id_prod[$id_produs] = $nume_attr;
$i++;
}
// var_dump(count($id_prod));
$nume = explode("%%", $csv_array_attributes[0]);
$csv[0] = $csv_array_attributes[0];
$i = 1;
foreach ($id_prod as $key => $value) {
// comment part
//$final_string = "";
//if (attr_name has attribute_value for product i ){
// $final_string.= attribute_value."%%";
//}else{
// $final_string.= "%%";
//}
//end comment part
$csv[$i] = $csv_array_attributes[$i]."%%".$final_string;
$i++;
}
//var_dump($csv_array_attributes[0])
//CREARE CSV
$file = fopen("attributes.csv","w+");
foreach ($csv as $line){
fputcsv($file,explode('%%',$line),"^","`");
}

Actually I only can give you a hint how I would create a array for csv.
// header
$csv[0][0] = "one";
$csv[0][1] = "two";
$csv[0][2] = "three";
$csv[0][3] = "four";
$csv[0][4] = "five";
// body
$csv[1][0] = "some";
$csv[1][1] = "values";
$csv[1][2] = "that";
$csv[1][3] = "could";
$csv[1][4] = "be";
$csv[2][0] = "here";
$csv[2][1] = "in";
$csv[2][2] = "this";
$csv[2][3] = "little";
$csv[2][4] = "array";
This is only a sample to view the array setup.
If you have set up the header, lets say by a for you can fill the 2 demensional array.
If this is set up you can use a foreach to build your CSV
Sample
$seperator = ";";
$ln = "\r\n";
$csv_output = "";
foreach($csv as $c){
foreach($c as $value){
$csv_output .= $value . $seperator;
}
$csv_output . $ln;
}
csv output
one;two;three;four;five;
some;values;that;could;be;
here;in;this;little;array;
a row;with an;;empty;field;
empty fields are no problem since you seperate them all with a ;

Structure of php JSON output

this is continued from another question i asked:
Listing out JSON data?
my search only returns 1 item, im pretty sure the problem lies somewhere in my php, im not too sure if im adding to the array properly, or it could be the javascript wich you can see on the above link, but i doubt it.
my php code:
function mytheme_ajax_response() {
$search = $_GET["search_text"];
$result = db_query("SELECT nid FROM {node} WHERE title LIKE '%s%' AND type = 'product_collection'", $search);
$noder = array();
while ($record = db_fetch_object($result)) {
$noder[] = $record;
}
$matches = array();
$i = 0;
foreach ($noder as $row) {
$node = node_load($row->nid);
$termlink = db_fetch_object(db_query("SELECT tid FROM {term_node} WHERE nid = %d", $row->nid));
$matches[$i]['title'] = $node->title;
$matches[$i]['link'] = $termlink->tid;
}
++$i;
$hits = array();
$hits['matches'] = $matches;
print json_encode($hits);
exit();
}
You appear to be incrementing your $i variable AFTER the foreach loop. Therefore, $i is always 0 throughout your loop, so you are always setting the title and link values for $matches[0].
Try this:
function mytheme_ajax_response() {
$search = $_GET["search_text"];
$result = db_query("SELECT nid FROM {node} WHERE title LIKE '%s%' AND type = 'product_collection'", $search);
$noder = array();
while ($record = db_fetch_object($result)) {
$noder[] = $record;
}
$matches = array();
foreach ($noder as $row) {
$node = node_load($row->nid);
$termlink = db_fetch_object(db_query("SELECT tid FROM {term_node} WHERE nid = %d", $row->nid));
$matches[] = array('title' => $node->title, 'link' => $termlink->tid);
}
$hits = array();
$hits['matches'] = $matches;
print json_encode($hits);
exit();
}
The $i wasn't incrementing the code as it was outside the foreach loop. By making a second array as above you don't need it anyway... (hope this works)...

How do I redistribute an array into another array of a certain "shape". PHP

I have an array of my inventory (ITEMS A & B)
Items A & B are sold as sets of 1 x A & 2 x B.
The items also have various properties which don't affect how they are distributed into sets.
For example:
$inventory=array(
array("A","PINK"),
array("A","MAUVE"),
array("A","ORANGE"),
array("A","GREY"),
array("B","RED"),
array("B","BLUE"),
array("B","YELLOW"),
array("B","GREEN"),
array("B","BLACK")
);
I want to redistribute the array $inventory to create $set(s) such that
$set[0] => Array
(
[0] => array(A,PINK)
[1] => array(B,RED)
[2] => array(B,BLUE)
)
$set[1] => Array
(
[0] => array(A,MAUVE)
[1] => array(B,YELLOW)
[2] => array(B,GREEN)
)
$set[2] => Array
(
[0] => array(A,ORANGE)
[1] => array(B,BLACK)
[2] => NULL
)
$set[3] => Array
(
[0] => array(A,GREY)
[1] => NULL
[2] => NULL
)
As you can see. The items are redistributed in the order in which they appear in the inventory to create a set of 1 x A & 2 x B. The colour doesn't matter when creating the set. But I need to be able to find out what colour went into which set after the $set array is created. Sets are created until all inventory is exhausted. Where an inventory item doesn't exist to go into a set, a NULL value is inserted.
Thanks in advance!
I've assumed that all A's come before all B's:
$inventory=array(
array("A","PINK"),
array("A","MAUVE"),
array("A","ORANGE"),
array("A","GREY"),
array("B","RED"),
array("B","BLUE"),
array("B","YELLOW"),
array("B","GREEN"),
array("B","BLACK")
);
for($b_start_index = 0;$b_start_index<count($inventory);$b_start_index++) {
if($inventory[$b_start_index][0] == 'B') {
break;
}
}
$set = array();
for($i=0,$j=$b_start_index;$i!=$b_start_index;$i++,$j+=2) {
isset($inventory[$j])?$temp1=$inventory[$j]:$temp1 = null;
isset($inventory[$j+1])?$temp2=$inventory[$j+1]:$temp2 = null;
$set[] = array( $inventory[$i], $temp1, $temp2);
}
To make it easier to use your array, you should make it something like this
$inv['A'] = array(
'PINK',
'MAUVE',
'ORANGE',
'GREY'
);
$inv['B'] = array(
'RED',
'BLUE',
'YELLOW',
'GREEN',
'BLACK'
);
This way you can loop through them separately.
$createdSets = $setsRecord = $bTemp = array();
$bMarker = 1;
$aIndex = $bIndex = 0;
foreach($inv['A'] as $singles){
$bTemp[] = $singles;
$setsRecord[$singles][] = $aIndex;
for($i=$bIndex; $i < ($bMarker*2); ++$i) {
//echo $bIndex.' - '.($bMarker*2).'<br/>';
if(empty($inv['B'][$i])) {
$bTemp[] = 'null';
} else {
$bTemp[] = $inv['B'][$i];
$setsRecord[$inv['B'][$i]][] = $aIndex;
}
}
$createdSets[] = $bTemp;
$bTemp = array();
++$bMarker;
++$aIndex;
$bIndex = $bIndex + 2;
}
echo '<pre>';
print_r($createdSets);
print_r($setsRecord);
echo '</pre>';
To turn your array into an associative array, something like this can be done
<?php
$inventory=array(
array("A","PINK"),
array("A","MAUVE"),
array("A","ORANGE"),
array("A","GREY"),
array("B","RED"),
array("B","BLUE"),
array("B","YELLOW"),
array("B","GREEN"),
array("B","BLACK")
);
$inv = array();
foreach($inventory as $item){
$inv[$item[0]][] = $item[1];
}
echo '<pre>';
print_r($inv);
echo '</pre>';
Maybe you can use this function, assuming that:
... $inventory is already sorted (all A come before B)
... $inventory is a numeric array staring at index zero
// $set is the collection to which the generated sets are appended
// $inventory is your inventory, see the assumptions above
// $aCount - the number of A elements in a set
// $bCount - the number of B elements in a set
function makeSets(array &$sets, array $inventory, $aCount, $bCount) {
// extract $aItems from $inventory and shorten $inventory by $aCount
$aItems = array_splice($inventory, 0, $aCount);
$bItems = array();
// iterate over $inventory until a B item is found
foreach($inventory as $index => $item) {
if($item[0] == 'B') {
// extract $bItems from $inventory and shorten $inventory by $bCount
// break out of foreach loop after that
$bItems = array_splice($inventory, $index, $bCount);
break;
}
}
// append $aItems and $bItems to $sets, padd this array with null if
// less then $aCount + $bCount added
$sets[] = array_pad(array_merge($aItems, $bItems), $aCount + $bCount, null);
// if there are still values left in $inventory, call 'makeSets' again
if(count($inventory) > 0) makeSets($sets, $inventory, $aCount, $bCount);
}
$sets = array();
makeSets($sets, $inventory, 1, 2);
print_r($sets);
Since you mentioned that you dont have that much experience with arrays, here are the links to the php documentation for the functions I used in the above code:
array_splice — Remove a portion of the array and replace it with something else
array_merge — Merge one or more arrays
array_pad — Pad array to the specified length with a value
This code sorts inventory without any assumption on inventory ordering. You can specify pattern (in $aPattern), and order is obeyed. It also fills lacking entries with given default value.
<?php
# config
$aInventory=array(
array("A","PINK"),
array("A","MAUVE"),
array("A","ORANGE"),
array("A","GREY"),
array("B","RED"),
array("B","BLUE"),
array("B","YELLOW"),
array("B","GREEN"),
array("B","BLACK"),
array("C","cRED"),
array("C","cBLUE"),
array("C","cYELLOW"),
array("C","cGREEN"),
array("C","cBLACK")
);
$aPattern = array('A','B','A','C');
$mDefault = null;
# preparation
$aCounter = array_count_values($aPattern);
$aCurrentCounter = $aCurrentIndex = array_fill_keys(array_unique($aPattern),0);
$aPositions = array();
$aFill = array();
foreach ($aPattern as $nPosition=>$sElement){
$aPositions[$sElement] = array_keys($aPattern, $sElement);
$aFill[$sElement] = array_fill_keys($aPositions[$sElement], $mDefault);
} // foreach
$nTotalLine = count ($aPattern);
$aResult = array();
# main loop
foreach ($aInventory as $aItem){
$sElement = $aItem[0];
$nNeed = $aCounter[$sElement];
$nHas = $aCurrentCounter[$sElement];
if ($nHas == $nNeed){
$aCurrentIndex[$sElement]++;
$aCurrentCounter[$sElement] = 1;
} else {
$aCurrentCounter[$sElement]++;
} // if
$nCurrentIndex = $aCurrentIndex[$sElement];
if (!isset($aResult[$nCurrentIndex])){
$aResult[$nCurrentIndex] = array();
} // if
$nCurrentPosition = $aPositions[$sElement][$aCurrentCounter[$sElement]-1];
$aResult[$nCurrentIndex][$nCurrentPosition] = $aItem;
} // foreach
foreach ($aResult as &$aLine){
if (count($aLine)<$nTotalLine){
foreach ($aPositions as $sElement=>$aElementPositions){
$nCurrentElements = count(array_keys($aLine,$sElement));
if ($aCounter[$sElement] != $nCurrentElements){
$aLine = $aLine + $aFill[$sElement];
} // if
} // foreach
} // if
ksort($aLine);
# add empty items here
} // foreach
# output
var_dump($aResult);
Generic solution that requires you to specify a pattern of the form
$pattern = array('A','B','B');
The output will be in
$result = array();
The code :
// Convert to associative array
$inv = array();
foreach($inventory as $item)
$inv[$item[0]][] = $item[1];
// Position counters : int -> int
$count = array_fill(0, count($pattern),0);
$out = 0; // Number of counters that are "out" == "too far"
// Progression
while($out < count($count))
{
$elem = array();
// Select and increment corresponding counter
foreach($pattern as $i => $pat)
{
$elem[] = $inv[ $pat ][ $count[$i]++ ];
if($count[$i] == count($inv[$pat]))
$out++;
}
$result[] = $elem;
}
