I am trying to get the column letter.
takes_column(item) is a method that should return the letter. The reason of this is to write in my DB the rigth column.
for ($i=2;$i<=$filas;$i++){
$_DATOS_EXCEL[$i]['item'] = $objPHPExcel->getActiveSheet()->getCell(takes_column(item).$i)->getCalculatedValue();
$_DATOS_EXCEL[$i]['warehouse'] = $objPHPExcel->getActiveSheet()->getCell(takes_column(item).$i)->getCalculatedValue();
$_DATOS_EXCEL[$i]['item_description'] = $objPHPExcel->getActiveSheet()->getCell(takes_column(item).$i)->getCalculatedValue();
}
}
function takes_column($input)
{
$row = $this->objPHPExcel->getActiveSheet()->getRowIterator(0)->current();
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);
foreach ($cellIterator as $cell) {
if ($cell->getValue() = $input){
return $cell->getColumn();
}
}
Map your column names into a lookup array before your main loop:
$headingData = $objPHPExcel->getActiveSheet()
->rangeToArray(
'A1:A' . $objPHPExcel->getActiveSheet()->getHighestColumn(),
null, true, true, true
);
$headings = array_flip($headingData[1]);
This should give you an array something like:
[
'item' => 'A',
'warehouse' => 'B',
'item_description' => 'C',
]
And you can then do a lookup against that headers array in your loop:
for ($i=2;$i<=$filas;$i++){
$_DATOS_EXCEL[$i]['item'] = $objPHPExcel->getActiveSheet()->getCell($headings['item'].$i)->getCalculatedValue();
$_DATOS_EXCEL[$i]['warehouse'] = $objPHPExcel->getActiveSheet()->getCell($headings['warehouse'].$i)->getCalculatedValue();
$_DATOS_EXCEL[$i]['item_description'] = $objPHPExcel->getActiveSheet()->getCell($headings['item_description'].$i)->getCalculatedValue();
}

So I have multiples empty arrays that I want to fill, let's say
$a_tab = [];
$b_tab = [];
$c_tab = [];
I have an array containing some data, let's say
$data = ['a' => 'foo', 'b' => 'bar', 'c' => 'foobar'];
I wanted to be able to do something like this :
foreach($data as $key => $value) {
$tab_name = $key . '_tab'; // so we have a variable that have the same name as one of the array we declared before
$$tab_name[$value] = $value; // this should add 'foo' into $a_tab, 'bar' in $b_tab and 'foobar' in $c_tab
}
But no value is ever added to any array...
Could someone explain me what did I do wrong ?
PS : if you don't want pseudo-code, here is the code that I had when I faced the issue :
// $tab is a parameter of the current function
$done_courses = []; // the array where we are going to put every courses that already have been added in one bifurcation tab
$regex_wz = '/\_werkzoekende/';
$regex_bd = '/\_bediende/';
$regex_op = '/\_outplacement/';
$bifurcation_keys = ['wz_tab' => $regex_wz, 'bd_tab' => $regex_bd, 'op_tab' => $regex_op];
// create the 3 arrays
$wz_tab = [];
$bd_tab = [];
$op_tab = [];
foreach($tab as $key => $value) {
foreach($bifurcation_keys as $tab_name => $regex) {
if(preg_match($regex, $key)) {
$n_k = preg_replace($regex, '', $key);
$$tab_name[$n_k] = $value;
if(!isset($done_courses[$n_k])) {
$done_courses[$n_k] = $n_k;
}
}
}
}
Did you try..
foreach($data as $key => $value) {
${$key.'_tab'}[$value] = $value;
}
I have this general data structure:
$levels = array('country', 'state', 'city', 'location');
I have data that looks like this:
$locations = array(
1 => array('country'=>'USA', 'state'=>'New York', 'city'=>'NYC', 'location'=>'Central Park', 'count'=>123),
2 => array('country'=>'Germany', ... )
);
I want to create hierarchical arrays such as
$hierarchy = array(
'USA' => array(
'New York' => array(
'NYC' => array(
'Central Park' => 123,
),
),
),
'Germany' => array(...),
);
Generally I would just create it like this:
$final = array();
foreach ($locations as $L) {
$final[$L['country']][$L['state']][$L['city']][$L['location']] = $L['count'];
}
However, it turns out that the initial array $levels is dynamic and can change in values and length So I cannot hard-code the levels into that last line, and I do not know how many elements there are. So the $levels array might look like this:
$levels = array('country', 'state');
Or
$levels = array('country', 'state', 'location');
The values will always exist in the data to be processed, but there might be more elements in the processed data than in the levels array. I want the final array to only contain the values that are in the $levels array, no matter what additional values are in the original data.
How can I use the array $levels as a guidance to dynamically create the $final array?
I thought I could just build the string $final[$L['country']][$L['state']][$L['city']][$L['location']] with implode() and then run eval() on it, but is there are a better way?
Here's my implementation. You can try it out here:
$locations = array(
1 => array('country'=>'USA', 'state'=>'New York', 'city'=>'NYC', 'location'=>'Central Park', 'count'=>123),
2 => array('country'=>'Germany', 'state'=>'Blah', 'city'=>'NY', 'location'=>'Testing', 'count'=>54),
);
$hierarchy = array();
$levels = array_reverse(
array('country', 'state', 'city', 'location')
);
$lastLevel = 'count';
foreach ( $locations as $L )
{
$array = $L[$lastLevel];
foreach ( $levels as $level )
{
$array = array($L[$level] => $array);
}
$hierarchy = array_merge_recursive($hierarchy, $array);
}
print_r($hierarchy);
Cool question. A simple approach:
$output = []; //will hold what you want
foreach($locations as $loc){
$str_to_eval='$output';
for($i=0;$i<count($levels);$i++) $str_to_eval .= "[\$loc[\$levels[$i]]]";
$str_to_eval .= "=\$loc['count'];";
eval($str_to_eval); //will build the array for this location
}

If your dataset always in fixed structure, you might just loop it
$data[] = [country=>usa, state=>ny, city=>...]
to
foreach ($data as $row) {
$result[][$row[country]][$row[state]][$row[city]] = ...
}
In case your data is dynamic and the levels of nested array is also dynamic, then the following is an idea:
/* convert from [a, b, c, d, ...] to [a][b][...] = ... */
function nested_array($rows, $level = 1) {
$data = array();
$keys = array_slice(array_keys($rows[0]), 0, $level);
foreach ($rows as $r) {
$ref = &$data[$r[$keys[0]]];
foreach ($keys as $j => $k) {
if ($j) {
$ref = &$ref[$r[$k]];
}
unset($r[$k]);
}
$ref = count($r) > 1 ? $r : reset($r);
}
return $data;
}
try this:
<?php
$locations = [
['country'=>'USA', 'state'=>'New York', 'city'=>'NYC', 'location'=>'Central Park', 'street'=>'7th Ave', 'count'=>123],
['country'=>'USA', 'state'=>'Maryland', 'city'=>'Baltimore', 'location'=>'Harbor', 'count'=>24],
['country'=>'USA', 'state'=>'Michigan', 'city'=>'Lansing', 'location'=>'Midtown', 'building'=>'H2B', 'count'=>7],
['country'=>'France', 'state'=>'Sud', 'city'=>'Marseille', 'location'=>'Centre Ville', 'count'=>12],
];
$nk = array();
foreach($locations as $l) {
$jsonstr = json_encode($l);
preg_match_all('/"[a-z]+?":/',$jsonstr,$e);
$narr = array();
foreach($e[0] as $k => $v) {
if($k == 0 ) {
$narr[] = '';
} else {
$narr[] = ":{";
}
}
$narr[count($e[0]) -1] = ":" ;
$narr[] = "";
$e[0][] = ",";
$jsonstr = str_replace($e[0],$narr,$jsonstr).str_repeat("}",count($narr)-3);
$nk [] = $ko =json_decode($jsonstr,TRUE);
}
print_r($nk);
Database have three field:
here Name conatin contry state and city name
id,name,parentid
Pass the contry result to array to below function:
$data['contry']=$this->db->get('contry')->result_array();
$return['result']=$this->ordered_menu( $data['contry'],0);
echo "<pre>";
print_r ($return['result']);
echo "</pre>";
Create Function as below:
function ordered_menu($array,$parent_id = 0)
{
$temp_array = array();
foreach($array as $element)
{
if($element['parent_id']==$parent_id)
{
$element['subs'] = $this->ordered_menu($array,$element['id']);
$temp_array[] = $element;
}
}
return $temp_array;
}
ok..I'm trying to re-map the keynames of a key-value array in php using a fieldmap array ie.
i want the $outRow array to hold $inRow['name1'] = 10 to $outRow['name_1'] = 10 for a large set of pre-mapped values..
$fieldmap=array("name1"=>"name_1","name2"=>"name_2");
private function mapRow($inRow) {
$outRow = array();
foreach($inRow as $key => $value) {
$outRow[$this->fieldmap[$key]][] = $value;
}
return $outRow;
} // end mapRow
public function getListings($inSql) {
// get data from new table
$result = mysql_query($inSql);
if (!result) {
throw new exception("retsTranslate SQL Error: $inSql");
}
while ($row = mysql_fetch_assoc($result)) {
$outResult[] = $this->mapRow($row);
}
return $outResult;
} // end getListings
this is not working..I'm getting the array but its using $outResult[0][keyname]...I hope this is clear enough :)
$fieldmap=array("name1"=>"name_1","name2"=>"name_2");
private function mapRow($inRow) {
$outRow = array();
foreach($inRow as $key => $value) {
$outRow[$this->fieldmap[$key]][] = $value;
}
return $outRow;
} // end mapRow
while ($row = mysql_fetch_assoc($result)) {
//$outResult[] = $this->mapRow($row);
$outResult[= $this->mapRow($row);
}
I commented your line of code and added new one..it definitely got what you mentioned in question.
If you can structure your arrays to where the keys align with the values (see example below) you can use PHP array_combine(). Just know that you will need to make absolutely sure the array is ordered correctly.
<?php
$fieldmap = array( 'name_1', 'name_2', 'name_3' );
private function mapRow($inRow)
{
$outRow = array_combine( $this->fieldmap, $inRow );
return $outRow;
}
For example, if your array was:
array( 'name1' => 10, 'name2' => 20, 'name3' => 30 );
The new result would be:
array( 'name_1' => 10, 'name_2' => 20, 'name_3' => 30 );
Let me know if this helps.
Try this:
function mapRow($inRow) {
$outRow = array();
foreach($inRow as $key => $value) {
$outRow[preg_replace('/\d/', '_$0', $key,1)] = $value;
}
return $outRow;
}
Hi all' I have a page into PHP where I retrieve XML data from a server and I want to store this data into an array.
This is my code:
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string)$entry2->attributes()->HOTEL_CODE;
$hotel_array2 = array();
$hotel_array2['id'] = $entry2->ID;
$hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME);
$i=0;
foreach($entry2->ROOM_DATA as $room){
$room_array = array();
$room_array['id'] = (string)$room->attributes()->CCHARGES_CODE;
$hotel_array2['rooms'][$i] = array($room_array);
$i++;
}
array_push($hotel_array, $hotel_array2);
}
}
In this mode I have the array hotel_array which all hotel with rooms.
The problem is that: into my XML I can have multiple hotel with same ID (the same hotel) with same information but different rooms.
If I have an hotel that I have already inserted into my hotel_array I don't want to insert a new array inside it but I only want to take its rooms array and insert into the exisiting hotel.
Example now my situation is that:
hotel_array{
[0]{
id = 1,
name = 'test'
rooms{
id = 1
}
}
[0]{
id = 2,
name = 'test2'
rooms{
id = 100
}
}
[0]{
id = 1,
name = 'test'
rooms{
id = 30
}
}
}
I'd like to have this result instead:
hotel_array{
[0]{
id = 1,
name = 'test'
rooms{
[0]{
id = 1
}
[1]{
id = 30
}
}
}
[0]{
id = 2,
name = 'test2'
rooms{
id = 100
}
}
}
How to create an array like this?
Thanks
first thing is it helps to keep the hotel id as the index on hotel_array when your creating it.
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string)$entry2->attributes()->HOTEL_CODE;
$hotel_array2 = array();
$hotel_array2['id'] = $entry2->ID;
$hotel_array2['name'] = utf8_decode($entry2->HOTEL_NAME);
$i=0;
foreach($entry2->ROOM_DATA as $room){
$room_array = array();
$room_array['id'] = (string)$room->attributes()->CCHARGES_CODE;
$hotel_array2['rooms'][$i] = array($room_array);
$i++;
}
if (!isset($hotel_array[$hotel_array2['id']])) {
$hotel_array[$hotel_array2['id']] = $hotel_array2;
} else {
$hotel_array[$hotel_array2['id']]['rooms'] = array_merge($hotel_array[$hotel_array2['id']]['rooms'], $hotel_array2['rooms']);
}
}
}
Whilst this is the similar answer to DevZer0 (+1), there is also quite a bit that can be done to simplify your workings... there is no need to use array_merge for one, or be specific about $i within your rooms array.
$hotels = array();
foreach ($xml->DATA as $entry){
foreach ($entry->HOTEL_DATA as $entry2){
$id = (string) $entry2->attributes()->HOTEL_CODE;
if ( empty($hotels[$id]) ) {
$hotels[$id] = array(
'id' => $id,
'name' => utf8_decode($entry2->HOTEL_NAME),
'rooms' => array(),
);
}
foreach($entry2->ROOM_DATA as $room){
$hotels[$id]['rooms'][] = array(
'id' => (string) $room->attributes()->CCHARGES_CODE;
);
}
}
}
Just in case it helps...
And this :)
$hotel_array = array();
foreach ($xml->DATA as $entry)
{
foreach ($entry->HOTEL_DATA as $entry2)
{
$hotel_code = (string) $entry2->attributes()->HOTEL_CODE;
if (false === isset($hotel_array[$hotel_code]))
{
$hotel = array(
'id' => $entry2->ID,
'code' => $hotel_code,
'name' => utf8_decode($entry2->HOTEL_NAME)
);
foreach($entry2->ROOM_DATA as $room)
{
$hotel['rooms'][] = array(
'id' => (string)$room->attributes()->CCHARGES_CODE,
);
}
$hotel_array[$hotel_code] = $hotel;
}
}
}
I have the following code
while($row = $usafisRSP->fetch_assoc()) {
$id = $row['id'];
$Applicantid = $row['Applicantid'];
$unique_num = $row['unique_num'];
// .................
$hidden_fields = array($Applicantid, $unique_num, $regs_t ....);
$hidden_values = array();
foreach ($hidden_fields as $key => $value) {
$hidden_values[$value] = "$key = ".base64_decode($value)."<br>";
echo $hidden_values[$value];
}
}
and the result is something like this
0 = 116153840
1 = 136676636
2 = 2010-12-17T04:12:37.077
3 = XQ376
4 = MUKANTABANA
I would like to replace 0, 1, 2, 3 etc with some custom values like "Id", "application name" to make the result like
id = 116153840
application name = 136676636
etc ..
how can I do that ?
Replace the $hidden_fields = array(... line with the following:
$hidden_keys = array('id', 'Applicantid', 'unique_num');
$hidden_fields = array_intersect_key($row, array_fill_keys($hidden_keys, NULL));
If you want to suppress all fields with value 0, either use
$hidden_fields = array_filter($hidden_fields, function($v) {return $v != 0;});
(this will completely omit the 0-entries) or
$hidden_fields = array_map($hidden_fields, function($v) {return ($v==0?'':$v);});
(this will leave them blank). If you're using an older version than 5.3, you'll have to replace the anonymous functions with calls to create_function.
I assume not every field in your row should be a hidden field. Otherwise you could just do $hidden_fields = $row.
I would create an array that specifies the hidden fields:
$HIDDEN = array(
'id' => 'Id',
'Applicantid' => 'application name',
'unique_num' => 'whatever'
);
And then in your while loop:
while(($row = $usafisRSP->fetch_assoc())){
$hidden_fields = array();
foreach$($HIDDEN as $field=>$name) {
$hidden_fields[$name] = $row[$field];
}
//...
foreach($hidden_fields as $name => $value) {
$hidden_fields[$name] = $name . ' = ' . base64_decode($value);
echo $hidden_values[$name];
// or just echo $name, ' = ',$hidden_fields[$value];
}
}
foreach ($row as $key => $value) {
$hidden_values[$value] = "$key = ".base64_decode($value)."<br>";
echo $hidden_values[$value];
}
This could give you something relevant. Through accessing the string keys from the row array which contains the string keys
