(PHP) Generic code to get different structure of arrays (objects)

(PHP) Generic code to get different structure of arrays (objects) - php

I have 2 structures of arrays (objects) returned :
1) If only 1 data returned :
stdClass Object
(
[result] => stdClass Object
(
[recordData] => stdClass Object
(
[fieldNames] => Array
(
[0] => CUSTOMER_ID_
[1] => EMAIL_ADDRESS_
[2] => FIRST_NAME
[3] => LAST_NAME
[4] => SEX
[5] => DATE_OF_BIRTH
)
**[records] => stdClass Object
(
[fieldValues] => Array
(
[0] => CUSTOMER_ID_001
[1] => email001#test.com
[2] => FIRST_NAME_001
[3] => LAST_NAME_001
[4] => M
[5] => 01/01/1991
)
)**
)
)
)
2) If more than 1 data returned :
stdClass Object
(
[result] => stdClass Object
(
[recordData] => stdClass Object
(
[fieldNames] => Array
(
[0] => CUSTOMER_ID_
[1] => EMAIL_ADDRESS_
[2] => FIRST_NAME
[3] => LAST_NAME
[4] => SEX
[5] => DATE_OF_BIRTH
)
**[records] => Array
(
[0] => stdClass Object
(
[fieldValues] => Array
(
[0] => CUSTOMER_ID_001
[1] => email001#test.com
[2] => FIRST_NAME_001
[3] => LAST_NAME_001
[4] => M
[5] => 01/01/1991
)
)
[1] => stdClass Object
(
[fieldValues] => Array
(
[0] => CUSTOMER_ID_002
[1] => email002#test.com
[2] => FIRST_NAME_002
[3] => LAST_NAME_002
[4] => F
[5] => 02/02/1992
)
)
)**
)
)
)
Currently i am using this code :
foreach ($memberlist->result->recordData->records as $list)
{
$out .= "<tr>";
foreach ($list as $memberarray)
{
foreach ($memberarray as $member)
{
$out .= "<td>" . $member . "</td>";
}
}
$out .= "</tr>";
}
but it does not work when only 1 data returned.
How can I modify my code to get both structures?
Thank You.

I believe this should do the trick:
// If it is already an array, leave it as an array, if it's not, place it in an array
$member_records = ( is_array( $memberlist->result->recordData->records ) ? $memberlist->result->recordData->records : array( $memberlist->result->recordData->records ) );
foreach ($member_records as $list)
{
$out .= "<tr>";
foreach ($list as $memberarray)
{
foreach ($memberarray as $member)
{
$out .= "<td>" . $member . "</td>";
}
}
$out .= "</tr>";
}

Combine some php sub-arrays, with condition

Using your actual result $admin_routes, you could loop through them and rebuild the desired array:
$real_routes = []; // The new array
$singles_key = ''; // The key for combined sub-arrays
$singles_routes = []; // The routes for combined sub-arrays
foreach ($admin_routes as $name => $r) {
/* If this route array has a single entry,
add its name and value to our temp vars */
if (count($r) === 1) {
$singles_key .= $name . ' ';
$singles_routes = array_merge($singles_routes, $r);
} else {
/* If then a route array has multiple value,
save the combined singles and then save this one */
if (!empty($singles_key)) {
$real_routes[trim($singles_key)] = $singles_routes;
$singles_key = '';
$singles_routes = [];
}
$real_routes[$name] = $r;
}
}
/* If the loop ends but the temp vars aren't empty,
save the lasts combined singles */
if (!empty($singles_key)) {
$real_routes[trim($singles_key)] = $singles_routes;
}
// Then to output:
echo '<pre>' . print_r($real_routes, true) . '</pre>';

How can I access multi-dimensional array with php?

My array is like this. So how can I access the names,values with php?
Array(
[0] => Array
(
[name] => subject
[value] => คอมพิวเตอร์ ม.3
)
[1] => Array
(
[name] => subject_code
[value] => ง33101
)
[2] => Array
(
[name] => subject_hour
[value] => 2
)
[3] => Array
(
[name] => semester
[value] => 1
)
[4] => Array
(
[name] => level
[value] => 3
)
[5] => Array
(
[name] => classroom
[value] => 301
)
[6] => Array
(
[name] => classroom
[value] => 302
)
)
I have tried FOREACH to loop through the array and it does the job, but how can I get their names and values to be used later?
My FOREACH code:
foreach($objects AS $values){
foreach($values as $value){
echo $value.'<br/>';
}
}

assume your array is $array:
foreach($array as $item){
$name = $item['name']; //extract name
$value = $item['value']; //extract value
echo $name.' '.$value.'</br>';
}

To get the index/key, just name it:
foreach($collection as $key => $value)
print($key . ' = ' . $value . '\n');

Iteration over $objects to get values and names;
foreach($objects as $value){
echo "Name: ".$value['name'];
echo " - Value: ".$value['value'];
echo "<br/>";
}

Read array-node with foreach, doesn't work

I have this array in a foreach-loop with the 'as' $train
Now i want to read out the 'mat'-node.
I've tried this:
<?php
echo "<!-- ";
foreach ($train['mat'] as $mat) {
echo "Mat:" . $mat . "";
}
echo " -->";
?>
But it gives a empty foreach result in mijn HTML-source, between the comments.
Array
(
[status] => 0
[via] => Utrecht C., Houten, Geldermalsen
[bestemming] => Tiel
[vleugels] => Array
(
[0] => Array
(
[stopstations] => Array
(
[0] => Array
(
[naam] => Vleuten
[code] => VTN
)
[1] => Array
(
[naam] => Utrecht Terwijde
[code] => UTT
)
[2] => Array
(
[naam] => Utrecht Leidsche Rijn
[code] => UTLR
)
)
[bestemming] => Tiel
[mat] => Array
(
[0] => Array
(
[0] => SLT-4
[1] => Tiel
[2] => 2422
)
[1] => Array
(
[0] => SLT-4
[1] => Tiel
[2] => 2464
)
)
)
)
[vervoerder] => NS
[spoor] => 6
)

Hope this help.
But I think you need read more about PHP Array and Array index
echo "<!-- ";
foreach($train['vleugels'][0]['mat'] as $mat) {
echo "Mat:".$mat[2]."<br>";
}
echo " -->";
// <!-- 2422 2464 -->

Ranking array base on key php

I have an array of object "$arr" like this:
Array
(
[0] => stdClass Object
(
[1] => 1
)
[1] => stdClass Object
(
[0] => 1
)
[2] => stdClass Object
(
[4] => 2
)
[3] => stdClass Object
(
[3] => 2
)
[4] => stdClass Object
(
[2] => 3
)
)
What I want to do is rank the value based on the key. If key($arr[$idx+1]) < key($arr[$idx]) then increase value of $arr[idx] by 1. So the results would look like:
Array
(
[0] => stdClass Object
(
[1] => 2
)
[1] => stdClass Object
(
[0] => 1
)
[2] => stdClass Object
(
[4] => 5
)
[3] => stdClass Object
(
[3] => 4
)
[4] => stdClass Object
(
[2] => 3
)
)
this is what I have done so far:
$arrIdx2=[];
foreach($arrIdx as $key=>$value){
$newVal = new stdClass();
$newVal->$key = $value;
$arrIdx2[] = $newVal;
}
foreach($arrIdx2 as $key=>$value){
$i= key((array)$value);
$m = $value->$i; //get the first value
for($j = $key+1; $j< $len; $j++){
$i2 = key((array)$arrIdx2[$j]); //get the key of second value
$n = $arrIdx2[$j]->$i2;
if($n == $m){
if($i2 < $i){
$arrIdx2[$key]->$i += 1;
}
}
}
}
and this is the result I got:
Array
(
[0] => stdClass Object
(
[1] => 2
)
[1] => stdClass Object
(
[0] => 1
)
[2] => stdClass Object
(
[4] => 3
)
[3] => stdClass Object
(
[3] => 2
)
[4] => stdClass Object
(
[2] => 3
)
)
What's the best way to do this? Can anyone guide me? Thanks

Do this with associative array. I can't make an object array
right now. If you provide me the object array then i will update my answer.
Try this:
$arr = array(
array("1" => 1),
array("0" => 1),
array("4" => 2),
array("3" => 2),
array("2" => 3)
);
$out = array();
$first = key(current($arr));
$end = key(end($arr));
foreach($arr as $key => $val){
$comp = (key($val) == $end) ? $end : key($arr[$key+1]);
if($comp <= key($val))
$out[$key][key($val)] = key($val) + 1;
else
$out[$key][key($val)] = $val[key($val)];
}
echo '<pre>';
print_r($out);
Result
Array
(
[0] => Array
(
[1] => 2
)
[1] => Array
(
[0] => 1
)
[2] => Array
(
[4] => 5
)
[3] => Array
(
[3] => 4
)
[4] => Array
(
[2] => 3
)
)
I think you want this, let me know.

Getting data from SimpleDB using PHP

Using XPath is going to perform about 100x faster. I haven't tested this code, but the XPath expression should be pretty close:
$msgAddress = (string) $response->body->query('//Attribute[Name[text()="msgAddress"]]/Value')->first();

I figured it out using some old Tarzan code. This works for a 2 dimensional array (data similar to a standard database)
Here is the working code:
<?php
// Include the SDK
require_once 'sdk.class.php';
// Instantiate
$sdb = new AmazonSDB();
$select_expression = 'SELECT * FROM ' . $domain_name;
$next_token = null;
do {
if ($next_token) {
$response = $sdb->select($select_expression, array(
'NextToken' => $next_token,
));
} else {
$response = $sdb->select($select_expression);
}
// Get Data for row
foreach ($response->body->SelectResult->Item as $item)
{
$msgId = $item->Name;
foreach ($item->Attribute as $attr)
{
if ($attr->Name == 'msgAddress') {
$msgAddress = $attr->Value;
}
if ($attr->Name == 'msgType') {
$msgType = $attr->Value;
}
if ($attr->Name == 'msgSubmitDate') {
$msgSubmitDate = $attr->Value;
}
if ($attr->Name == 'msgText') {
$msgText = $attr->Value;
}
}
echo "<br>msgId: $msgId<br>";
echo "msgAddress: $msgAddress<br>";
echo "msgType: $msgType<br>";
echo "msgSubmitDate: $msgSubmitDate<br>";
echo "msgText: $msgText<br><br>";
}
$next_token = isset($response->body->SelectResult->NextToken)
? (string) $response->body->SelectResult->NextToken
: null;
}
while ($next_token);
echo "<br>";
?>

$body = $response->body->to_array()->getArrayCopy();
echo "ID: " . $msgId . "<br>";
//but $msgId is not set
