I have an array ... Here is the structure / data:
array(1) {
[0]=> object(SimpleXMLElement)#1 (18)
{
["data_123"]=> object(SimpleXMLElement)#3 (29)
{
["field1"]=> string(7) "123"
["field2"]=> string(2) "10"
["field3"]=> string(19) "2013-03-05 17:00:00"
["field4"]=> string(19) "2013-03-05 18:00:00"
}
["data_234"]=> object(SimpleXMLElement)#4 (29)
{
["field1"]=> string(7) "234"
["field2"]=> string(2) "10"
["field3"]=> string(19) "2013-03-05 17:40:00"
["field4"]=> string(19) "2013-03-05 18:10:00"
}
}
}
I am trying to create a loop to display the data but nothing is showing up:
foreach ($result as $key => $list) {
echo "key.: " . $key . "\n";
echo "field1: " . $list['field1'] . "\n";
echo "field2: " . $list['field2'] . "\n";
}
It's just not returning any data.
I'm guessing that the loop might be wrong for this array structure?
How can I get the data echoed for this array?
$list is an array of objects so you need two loops and appropriate syntax. e.g.:
foreach($list as $objects) {
foreach($objects as $key => $obj) {
echo "key.: " . $key . "\n";
echo $obj->field1 . "\n";
echo $obj->field2 . "\n";
echo $obj->field3 . "\n";
echo $obj->field4 . "\n";
}
}

I got an array of coins with many details, that looks partially like that:
array(360) {
["VEN/USDT"]=>
array(15) {
["tierBased"]=>
bool(false)
}
["id"]=>
string(7) "VENUSDT"
["symbol"]=>
string(8) "VEN/USDT"
["base"]=>
string(3) "VEN"
["quote"]=>
string(4) "USDT"
["lot"]=>
float(0.01)
["active"]=>
bool(true)
}
All I need is this part:
["id"]=>
string(7) "VENUSDT"
["symbol"]=>
string(8) "VEN/USDT"
["base"]=>
string(3) "VEN"
["quote"]=>
string(4) "USDT"
if "base" is more often than once in the entire array.
The final code was:
$base_array = array();
foreach ($markets as $key=>$value) {
echo "1. Key = " . $key . "\n";
foreach ($value as $key => $value) {
if ($key == "base") {
echo "Base = " . $value . "\n";
array_push($base_array, $value);
}
}
}
// Duplicates we need only!
$unique = array_unique($base_array);
$duplicates1 = array_diff_assoc($base_array, $unique);
$duplicates = array_unique($duplicates1);
var_dump($duplicates);
I am working with an API which provides a result set in JSON, I transform that data into a PHP array to work with it on my interface.
The issue i'm having now is trying to filter the data based on a particular key having a certain value.
Here is the result set returned:
[
{
"id":5,
"firstname":"Joel ",
"lastname":"Abase",
"displayName":"Abase, Joel ",
"officeId":3,
"officeName":"Birmingham",
"isLoanOfficer":true,
"isActive":true
},
{
"id":1,
"firstname":"Precious ",
"lastname":"Love",
"displayName":"Love, Precious ",
"officeId":4,
"officeName":"Manchester",
"isLoanOfficer":true,
"isActive":true
},
{
"id":2,
"firstname":"Bernard ",
"lastname":"Aikins",
"displayName":"Aikins, Bernice ",
"officeId":2,
"officeName":"Manchester",
"isLoanOfficer":false,
"isActive":true
},
{
"id":8,
"firstname":"Kwame",
"lastname":"Joseph",
"displayName":"Joseph, Kwame",
"officeId":2,
"officeName":"Manchester",
"isLoanOfficer":true,
"isActive":true,
"joiningDate":[
2018,
5,
1
]
},
{
"id":4,
"firstname":"Janine ",
"lastname":"Hayden",
"displayName":"Hayden, Janine ",
"officeId":1,
"officeName":"Head Office",
"isLoanOfficer":false,
"isActive":true
},
{
"id":6,
"firstname":"Esther",
"lastname":"Monroe",
"displayName":"Monroe, Esther",
"officeId":2,
"officeName":"London",
"isLoanOfficer":true,
"isActive":true,
"joiningDate":[
2017,
11,
1
]
}
]
I would like to filter the results in a loop where the 'isLoanOfficer' is equal to true, essentially only showing those who are loan officers.
Here is what I have tried so far:
<div class="col-sm-5">
<label class="control-label" for="staffId">Loan Officer<span style="color:red;">*</span></label>
<?php
$s = 0;
$temp_staff = json_decode($staff_json, true);
$count_staff = count($temp_staff);
echo '<select class="form-control" type="text" name="staffId" required>';
echo "<option value=". ">" . " </option>";
while($s < $count_staff && $temp_staff[$s]['isLoanOfficer'] == true){
echo "<option value=" . $temp_staff[$s]['id'] . ">" . $temp_staff[$s]['displayName'] . " </option>";
$s++;
}
echo '</select>';
?>
<br>
</div>
I also tried adding this code inside the while loop:
if($temp_staff[$s]['isLoanOfficer'] == true) {
echo "<option value=" . $temp_staff[$s]['id'] . ">" . $temp_staff[$s]['displayName'] . " </option>";
$s++;
}
It seems that it only evaluates the first value and then exits. Any help?
You'll have to use the condition inside the loop. Try the below code :
while($s < $count_staff){
if ($temp_staff[$s]['isLoanOfficer'] == true) {
echo "<option value=" . $temp_staff[$s]['id'] . ">" . $temp_staff[$s]['displayName'] . " </option>";
}
$s++;
}
Due to that condition your $s++ is not being executed properly.
Hope this helps.
You do not need to loop.
You can use array_intersect, array_intersect_key and array_column to find the true values.
First filter out the loanofficer column and use array_intersect to only get the true values.
Now we have an array with true values and it's corresponding key.
Use array_intersect_key to match it with the original array and the return is your filtered array.
$arr = json_decode($str, true);
$loan = array_intersect(array_column($arr, "isLoanOfficer"), [true]);
var_dump(array_intersect_key($arr, $loan));
From here is't a simple foreach outputing every value or use implode to build the output string.

If you want to keep the arrays which only have "isLoanOfficer":true you could use array_filter:
$temp_staff = array_filter($temp_staff, function($x){
return $x["isLoanOfficer"] === true;
}
);
Demo
The easiest and most readable way, using a foreach:
$temp_staff = json_decode($staff_json, true);
foreach($temp_staff as $member) {
if($member['isLoanOfficer']) {
echo '<option value="' . $member['id'] . '">' . $member['displayName'] . '</option>';
}
}
I'm using Google's Natural Language API and it's working fine and returning data. I'm just not able to parse it correctly. I'd like to form a JSON object I can then use with AJAX or similar. What I need out of this are mainly the sentences and their sentiment. I'm struggling with this object that I get back:
object(Google\Cloud\NaturalLanguage\Annotation)#21 (1) {
["info":"Google\Cloud\NaturalLanguage\Annotation":private]=>
array(3) {
["documentSentiment"]=>
array(2) {
["magnitude"]=>
float(1.4)
["score"]=>
int(0)
}
["language"]=>
string(2) "en"
["sentences"]=>
array(2) {
[0]=>
array(2) {
["text"]=>
array(2) {
["content"]=>
string(19) "I love everything!\"
["beginOffset"]=>
int(0)
}
["sentiment"]=>
array(2) {
["magnitude"]=>
float(0.8)
["score"]=>
float(0.8)
}
}
[1]=>
array(2) {
["text"]=>
array(2) {
["content"]=>
string(18) "I hate everything!"
["beginOffset"]=>
int(21)
}
["sentiment"]=>
array(2) {
["magnitude"]=>
float(0.6)
["score"]=>
float(-0.6)
}
}
}
}
}
ADDED:
The very last bit of my PHP code is:
$annotation = $language->analyzeSentiment($text);
$sentiment = $annotation->sentiment();
echo 'Text: ' . $text . '
Sentiment: ' . $sentiment['score'] . ', ' . $sentiment['magnitude'];
return $sentiment;
This successfully returns the score and magnitude for the overall "document" as shown in the part of the array under "documentSentiment". What I need (in addition to this), is the data under sentences. In particular, content, magnitude and score.
Since $sentiment['sentences'] is an array -
["sentences"]=>
array(2) {
...
}
you need to loop over the values, with foreach() for example -
....
echo 'Text: ' . $text . '
Sentiment: ' . $sentiment['score'] . ', ' . $sentiment['magnitude'];
foreach($sentiment['sentences'] as $sentence){
echo 'Text: ' .$sentence["text"]["content"] . '
Sentiment: ' . $sentence["sentiment"]["score"] . ', ' . $sentence["sentiment"]["magnitude"];
}

This is what I get when I call my API, now this is just one sample. If you see there is [0] which indicates entry 1 and than [1] which indicates entry two. There are more but I have shortened it. Right now I can do this
foreach ($null_check['value'] as $key => $data) {
// Get rid of '_' in Website Names
$new = str_replace('_', ' ', $data['PartitionKey']);
echo 'Website: '.$new.'<br>';
echo 'Email: '.$data['Email'].'<br>';
}
Which allows me to get ALL of the Email and such
But what I want is to be able to take [0] and format that so doing a loop. It has something to do with i++ but I don't really understand it.
Here is what I really want:
PartitionKey: AWT-GPI.com
Email: ginyoung30#gmail.com
First Name: Jennifer
Last Name: Young
Hash: d656d0c21b8f3c14fe03232bb68d1b53
As you can see I've taken out some of the things and rearranged it. I was wondering if this is possible by using foreach. However, each entry might be different, so [1] might not have 'email' or 'first_name'
Thank you in advanced.
Update:
After some coding I got until here
$count = count($null_check);
for ($i = 0; $data < $count; $i++) {
foreach ($null_check['value'][$i] as $key => $data) {
$parsed_key = str_replace('_', ' ', $key);
echo $parsed_key.': '.$data.'<br>';
}
echo '<br><br>';
}
This allows me to just echo all the details but I have no idea which data is which and how to organize it.

See if this helps:
foreach($jsonArray as $jsonObj)
{
foreach($jsonObj as $key => $value)
{
if ($key === "PartitionKey" ||
$key === "Email" ||
$key === "First_Name" ||
$key === "Last_Name" ||
$key === "Hash") {
echo $key . ": " . $value . "<br>";
}
}
}
Assuming you have json_decode($json) of JSON array of objects.
foreach ($null_check['value'] as $key => $data) {
if(isset($data['PartitionKey'])){
$parsed_website = str_replace('_', ' ', $data['PartitionKey']);
echo 'Website: '.$parsed_website.'<br>';
}
if(isset($data['Username'])){
echo 'Username: '.$data['Username'].'<br>';
}
if(isset($data['Email'])){
echo 'Email: '.$data['Email'].'<br>';
}
if(isset($data['Hash'])){
echo 'Hash: '.$data['Hash'].'<br>';
}
if(isset($data['Salt'])){
echo 'Salt: '.$data['Salt'].'<br>';
}
if(isset($data['First_name'])){
echo 'First Name: '.$data['First_Name'].'<br>';
}
if(isset($data['Last_Name'])){
echo 'Last Name: '.$data['Last_Name'].'<br>';
}
if(isset($data['IP_1'])){
$null_ip = array('0000-00-00', null);
if(!in_array($data['IP_1'], $null_ip)) {
echo 'Registered IP: '.$data['IP_1'].'<br>';
}
}
echo '<br><br>';
}
I just did a isset to chcek if there was a key. This will go through all the array. Thank you for helping but this worked for me.
I have the following query:
$sth = $this->db->prepare("SELECT * FROM comment WHERE status = 1");
$sth->setFetchMode(PDO::FETCH_ASSOC);
$sth->execute();
$reviews = array();
while($row = $sth->fetch()){
$reviews[]['name'] = $row['name'];
$reviews[]['comment'] = $row['comment'];
$reviews[]['star'] = $row['star'];
}
return $reviews;
}
Which returns the following for var_dump($this->reviews):
array(9) {
[0]=> array(1) { ["name"]=> string(5) "name1" }
[1]=> array(1) { ["comment"]=> string(8) "comment1" }
[2]=> array(1) { ["star"]=> string(1) "4" }
[3]=> array(1) { ["name"]=> string(5) "name2" }
[4]=> array(1) { ["comment"]=> string(8) "comment2" }
[5]=> array(1) { ["star"]=> string(1) "4" }
[6]=> array(1) { ["name"]=> string(5) "name3" }
[7]=> array(1) { ["comment"]=> string(8) "comment3" }
[8]=> array(1) { ["star"]=> string(1) "4" }
}
How can I use foreach to display name, comment, star by row?
I.e.:
name1, email1#email.com, comment1
name2, email2#email.com, comment2
name3, email3#email.com, comment3
I know it should be something like:
foreach( $this->reviews as $key){
echo "Name:". $this->reviews['name'] . "Email:" . $this->reviews['email'] . "Comment:" . $this->reviews['comment'];
}
But this gives me Notice: Undefined index: name. How do I define the index?
You are setting up the insert into the array incorrectly:
while($row = $sth->fetch()){
$reviews[]['name'] = $row['name'];
$reviews[]['comment'] = $row['comment'];
$reviews[]['star'] = $row['star'];
}
The shorthand [] inserts a new element each and every single time, you want to actually insert an array AS the element.
while($row = $sth->fetch()){
$revArr=array('name' => $row['name'], 'comment' => $row['comment'], 'star' => $row['star']);
$reviews[]=$revArr;
}
Edit: Now change your second foreach to this:
foreach( $this->reviews as $key){
echo "Name:". $key['name'] . "Email:" . $key['email'] . "Comment:" . $key['comment'];
}
You need to generate an array of arrays. Something like
while($row = $sth->fetch()){
$reviews[] = array('name' => $row['name'], 'comment' => $row['comment'], 'star'=> $row['star']);
}
Now your $reviews object will have just as many elements as there were rows in the query result, and you can print it any way you want.
As for printing (which I think is where your error message is coming from):
foreach($reviews as $thisValue) {
echo "Name: ". $value['name'];
}
should work.
You should use your foreach loop like this:
foreach( $this->reviews as $value){
echo "Name:". $value['name'] . "Email:" . $value['email'] . "Comment:" . $value['comment'];
}
Notice how i use $value instead of $this->reviews inside the loop.
foreach( $this->reviews as $key){
echo "Name:". $this->reviews['name'] . "Email:" . $this->reviews['email'] . "Comment:" . $this->reviews['comment'];
}
this is not the right way, because now you are working on $key so write -
foreach( $this->reviews as $key){
echo "Name:". $key['name'] . "Email:" . $key['email'] . "Comment:" . $key['comment'];
}
you can do it as follow:
$reviews = array();
while($row = $sth->fetch()){
$reviews[] = array($row['name'], $row['comment'], $row['email'], $row['star']);
}
and then you can do a heredoc:
$str = '';
foreach( $this->reviews as $review ){
$str .=<<<html
name: {$review['name']}
email: {$review['email']}
comment: {$review['comment']}
start: {$review['star']}
html;
}
finally i echo everything:
echo $str;
I think this is much cleaner, and you can add any html.
