I am a little confused about the array_search function (or maybe I am trying to use the incorrect thing.) I have a bunch of transaction objects, (transactions about a customer) each is an array of values. After passing in an email address, I get an object that is one transaction where that email address was used. Example is below. I get it from the command print_r($results):
stdClass Object
(
[OverallStatus] => OK
[RequestID] => 4564564654-65465464565-4654654
[Results] => Array
(
[0] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 5555555555
[email_addy] => someaddy#something.com
)
[1] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 6666666666
[email_addy] => someaddy#something.com
)
[2] => stdClass Object
(
[thing1] =>
[thing2] =>
[Status] => Active
[ID] => 6666666666
[email_addy] => someaddy#something.com
)
)
)
I get this output with no trouble at all. My issue is that I need to identify when someone has a specific ID. I was trying to use a foreach but I am not getting back what I need. The code and output is below.
foreach ($results as $key => $value) {
echo "Key: $key; Value: $value<br />\n";
}
Output is
Key: OverallStatus; Value: OK
Key: RequestID; Value: 4564564654-65465464565-4654654
Key: Results; Value: Array
All I really need to know is if the customer has an ID of 5555555555. This number will always stay the same. Am I going in the wrong direction here?
You have array of object , so you should get first the array results , and then iterate over it,try this :
foreach ($results->Results as $key => $value) {
if($value->ID == 55555555) echo 'found at position'.$key;//if id is unique , add a break;
}
You need to iterate through $results->Results.
foreach ($results->Results as $key => $value) {
if($value->ID == 5555555555)
print "Match found";
}
You should loop again for results array. Try following foreach
foreach ($results as $key => $value) {
if($key == "Results") {
foreach($value as $v) {
if($v->ID == "5555555555") {
echo "I found you";
break;
}
}
} else {
echo "Key: $key; Value: $value<br />\n";
}
}
Loop through '$results->Results' and check in loop if the ID=5555555555 like this:
foreach ($results->Results as $value) {
if($value->ID == 5555555555) {
//do something
}
}
It would be something like the following:
$transactions = $results->Results; //get results array
foreach ($transactions as $transaction) { // loop through each transaction object.
echo $transaction->ID . '<br />'; // print out the id of each transaction.
}

I don't know how to say it in the title, but you'll understand with an example.
I've a database, where I store data in column named propriety and another column value. When I do my SQL request, I get this:
Array
(
[0] => Array
(
[propriety] => propriety1
[value] => value1
)
[1] => Array
(
[propriety] => propriety2
[value] => value2
)
[2] => Array
(
[propriety] => propriety3
[value] => value3
)
I would like to display it like this one:
Propriety : Value
But when I do my 2 foreach:
foreach ($array as $key => $value) {
foreach ($value as $k => $v) {
echo $k . ' : ' . $v . '<br>';
}
}
It returns:
Propriety : Propriety1
Value : Value1
etc ..
You don't need two foreach loops to do this, it can be done with one:
foreach ($array as $row) {
echo $row['propriety'].' : '.$row['value'].'<br>';
}
Assuming you actually want the values returned by the database.
Here's an alternative extracting value and re-indexing by propriety:
foreach(array_column($array, 'value', 'propriety') as $propriety => $value) {
echo "$propriety : $value<br>";
}
This assumes that each propriety will be unique.
Array
(
[edit] => true
[id] => 1
[type] => Array
(
[0] => LC
)
[userid] => 1
[norooms] => 1
[park] => Central
[start] => 09:00
[end] => 11:00
[length] => 2
[student] => 79
[status] => Rejected
)
<?php
$posted_data = array();
if (!empty($_POST['edit'])) {
$posted_data = json_decode($_POST['editVal'], true);
}
print_r ($posted_data);
foreach ($posted_data as $key => $value) {
echo '<p>'.$key.'</p>';
echo '<p>'.$value.'</p>';
}
?>
The array at the top is the jason_decode returned. However with my foreach function it does not display the first index of the array within the array. ie. ( [0] => LC ).
Where am I going wrong?
You need to build a recursive function, something like:
function print_recursively(array $array)
{
foreach ($array as $key => $value)
{
if(is_array($value))
{
print_recursively($value);
}
else
{
echo '<p>'.$key.'</p>';
echo '<p>'.$value.'</p>';
}
}
}
Tune it according to your needs.
If you know there is array hierarchy to one level only
Keep printing the values and if the value is an array using is_array.. Iterate again.
foreach($dataArray as $key =>$value){
if(is_array($value)){
foreach($value as $array2Data){
echo $array2Data; //you can use keys as well
}
}
else
echo $value;
}
I'm trying to print array. All code working fine with foreach loop. But I'm trying to print with associated keys. Is it possible?
Example: key['user_id'] this will print all user_id from array. is it possible? please help me thanks
Array
(
[Post1] => Array
(
[id] => 1
[title] => hi
)
[Post2] => Array
(
[0] => Array
(
[user_id] => 1
)
[1] => Array
(
[user_id] => 2
)
)
[Post3] => Array
(
[0] => Array
(
[user_name] => 1
)
)
)
Here is my PHP code:
foreach($post as $key => $value) {
foreach($value as $print => $key) {
if (is_array($key)){
foreach($key as $print2 => $key2) {
echo "<br>".$key2;
}
}else{
echo "<br>".$key;
}
}
}
You can print_r to achive the same results you want with your triple for each.

You can easily use recursion for such a problem. You can use something along the lines of:
function printValuesByKey($array, $key) {
if (!is_array($array)) return;
if (isset($array[$key]))
echo $key .': '. $array[$key] .'<br>';
else
foreach ($array as $v)
printValuesByKey($v, $key);
}
In your example:
printValuesByKey($array, 'user_id');
will print:
user_id: 1
user_id: 2
I'm trying to print array. All code working fine.But at last I'm getting `ArrayArray'. Can any one solve this problem. many many thanks
here is my array
Array

[Post1] => Array
(
[id] => 1
[title] => hi
)
[Post2] => Array
(
[0] => Array
(
[id] => 1
)
)
[Post3] => Array
(
[0] => Array
(
[id] => 1
)

Here is my PHP Code
foreach($post as $key => $value) {
foreach($value as $print => $key) {
echo "<br>".$key;
}
}
here is output

Array
Try this:
foreach($post as $key => $value) {
foreach($value as $print => $key) {
if (is_array($key)){
foreach($key as $print2 => $key2) {

}
}else{
echo "<br>".$key;
}
}
}
The to string method of an array is to return "Array".
It sounds like you want to view the array for debugging purposes. var_dump() is your friend :)
you are trying to print an array, resulting in Array.
If you want to print an array use print_r
I think the trouble for you is that you have $key in the outer loop and $key in the inner loop so its really confusing which $key you are talking about for starters.
You just want the stuff printed out to debug?
echo "<pre>" . print_r( $post , true ) . "</pre>\n";
foreach ($_GET as $field => $label) {
$datarray[]=$_GET[$field];
echo "$_GET[$field]";
echo "<br>";
This is the output I am getting. I see the data is there in datarray but when I echo $_GET[$field] I only get "Array"
But print_r($datarray) prints all the data. Any idea how I pull those values?
OUTPUT:
Array (
[0] => Array (
[0] => Grade1
[1] => ln
[2] => North America
[3] => yuiyyu
[4] => iuy
[5] => uiyui
[6] => yui
[7] => uiy
[8] => 0:0:5
)
)
foreach ($_GET as $key => $value)
{
if(is_array($value))
{
foreach($value as $childKey => $childValue)
{
echo $childKey." ".$childValue; // or assign them to an array
}
}
else
echo $key." ".$value; // or assign them to an array
}
Seems like $_GET[$field] is basically $_GET[0], which is an array:
You'll have to loop through $_GET[$field] with a forloop to get the content to echo out. By the way you can't echo array you'll have to use print_r
something like this:
foreach ($_GET as $field => $label) {
$datarray[]=$_GET[$field];
for($i=0; $i<$_GET[$field]; $i++){
echo $_GET[$field][$i];
}
echo "<br>";
}
EDIT: When I completed your test, here was the final URL:
http://hofstrateach.org/Roberto/process.php?keys=Grade1&keys=Nathan&keys=North%20America&keys=5&keys=3&keys=no&keys=foo&keys=blat&keys=0%3A0%3A24>
This is probably a malformed URL. When you pass duplicate keys in a query, PHP makes them an array. The above URL should probably be something like:
http://hofstrateach.org/Roberto/process.php?grade=Grade1&schoolname=Nathan®ion=North%20America&answer[]=5&answer[]=3&answer[]=no&answer[]=foo&answer[]=blat&time=0%3A0%3A24
This will create individual entries for most of the fields, and make $_GET['answer'] be an array of the answers provided by the user.
Bottom line: fix your Flash file.
