Assign foreach variables - php

I've tried, believe me I've tried to figure this out but for the best part of the day it has beaten me so I have to ask this question:
I have a list ($list) of 100 words which I have put into an array:
foreach ($tag_array as $key => $names ) {
Each of these names I want to be a variable which I can use to assign some html for output within a html eg:
$arrayitem6 = 'whatever';
print $arrayitem6;
The reason I want to do this is because the 100 items in the list actually turns into 400 items in a html page which I would have to manually write out into a huge long repeating block of html. I want to create a single block of html/code using the array list and foreach.
I hope I've made myself understood. I'm sure it's a straight forward bit of coding but as a novice I cannot fathom.
thanks in advance for any help
I have searched the internet and googled but I can't locate an answer. I'll keep looking.
thanks

Try following
<?php
foreach ($tag_array as $key => $names ) {
${"arrayitem$key"} = $names;
}
echo $arrayitem0;
?>
You can access variable as $arrayitem0, $arrayitem0 and so on depending upon key ($key) of your $tag_array

I think this is what you are looking for.
<?php
foreach ($tag_array as $key => $names ) {
$."arrayitem".$key = $names;
}
echo $arrayitem6;
?>
you can access variable as $arrayitem0 ,$arrayitem1...till 99

How to put foreach in array

I have this
$homedata = $user->getbanks();
foreach ($homedata as $data)
echo json_encode(array("replies" => array(array("message" => $data->bankname))));
I have this put the result am getting is only one array from the list. I want to get all.
If I understand your requirement correctly, you need the banknames in an array replies within a key message. For that the below code will do the job. But you can optimize the query for better performance.
$homedata = $user->getbanks();
$banks['replies'] = [];
foreach ($homedata as $data) {
$banks['replies'][]['message'] = $data->bankname;
}
print_r(json_encode($banks)); exit;
Further, you were only getting the first content because you are overriding the previous content when you iterate using foreach.

Multidimensional array into POST call using foreach loop PHP

Looking for some advise with regards to multidimensional Arrays, pushing the vars into a POST call within a foreach loop.
I currently have a foreach loop containing an IF clause:
foreach ($responseData['data'] as $key => $value) {
if (strtotime($value['attributes']['created_time']) > $currentDateMinusThirtyMinutes) {
array_push($emails, $value['attributes']['email']);
}
}
This is supposed to fetch the Email for all arrays which meet the condition of being created in the last 30 minutes.
However, now i am stuck, I need to fetch multiple other variables and call on a POST call similar to the below:
https://developer.example.co.za/{$PAGE}/create?reference={$ID}&currency=ZAR&amount={$AMOUNT}&firstname={$FIRST}&lastname={$LAST}&email={$EMAIL}&sendmail=true
What i need to know is, is there a better way to treat the foreach loop?
Is foreach the right way to go?
In essence I would need to run through each of the $responseData['data'] returns and make a POST call to the above URL.
Any advise would be appreciated.
Fixed this by creating a Data_array which stored the values I required, then adding the POST call inside the foreach loop which then did the trick.
The foreach ended up looking like this:
foreach ($responseData['data'] as $key => $value) {
if (strtotime($value['attributes']['created_time']) > $currentDateMinusThirtyMinutes) {
$data_array[] = array(
"id" => $value['attributes']['id'],
***add rest of vars you want***
);
***Add POST call or whatever else you want to do***
}
}
Thanks #darklightcode for pointing me to the idea of splitting out just the variables I wanted.

PHP - Looping through an object keys, one cycle per key

I have this object containing one row and many keys/variables with numbered names.
I need to pass each of them one at a time to another function. How do I loop through the keys instead of the rows?
The code would look like this:
foreach ($object['id'] as $row):
$i++;
$data['myInfo'][$i] = $this->get_data->getInfo('data1', 'id', $row->{'info'.$i.'_id'});`
but this obviously won't work since it's looping through the rows/instances of an object, and I have only one row in my $object['id'] object (with info1_id, info2_id, info3_id, info4_id... etc keys), so the loop stops after just one cycle. And I really don't feel like typing all of that extra code by hand, there's gotta be solution for this. :)
You can just iterate through your object like an array :
foreach ($object['id'] as $row) {
foreach ($row as $k => $v) {
$id = substr($k, 4, strpos($k, '_')-4);
$data['myInfo'][$id] = $this->get_data->getInfo('data1', 'id', $v);`
}
}
Thanks for the directions Alfwed, I didn't know you could use foreach loop for anything other than instances of an object or arrays (only started learning php a week or so ago), but now it looks pretty straight forward. that's how I did it:
foreach ($object['id'] as $row):
foreach ($row as $k=>$v):
$i++;
if ($k == print_r ('info'.$i.'_id',true)){
$data['myinfo'][$i] = $this->get_db->getRow('products', 'id','info'.$i.'_id');
<...>
in my case, I knew how many and where were those values, so I didn't have to worry about index values too much.

how to get the index of an array using the value in php

<?php
$interests[50] = array('fav_beverages' => "beer");
?>
now i need the index (i.e. 50 or whatever the index may be) from the value beer.
I tried array_search(), array_flip(), in_array(), extract(), list() to get the answer.
please do let me know if I have missed out any tricks for the above functions or any other function I`ve not listed. Answers will be greatly appreciated.
thanks for the replies. But for my disappointment it is still not working. btw I have a large pool of data like "beer");
$interests[50] = array('fav_cuisine' => "arabic");
$interests[50] = array('fav_food' => "hummus"); ?> . my approach was to get the other data like "arablic" and "hummus" from the user input "beer". So my only connection is via the index[50].Do let me know if my approach is wrong and I can access the data through other means.My senior just informed me that I`m not supposed to use loop.
This should work in your case.
$interests[50] = array('fav_beverages' => "beer");
function multi_array_search($needle, $interests){
foreach($interests as $interest){
if (array_search($needle, $interest)){
return array_search($interest, $interests);
break;
}
}
}
echo multi_array_search("beer", $interests);
If your array contains multiple sub-arrays and you don't know which one contains the value beer, then you can simply loop through the arrays, and then through the sub-arrays, to search for the value, and then return the index if it is found:
$needle = 'beer';
foreach ($interests as $index => $arr) {
foreach ($arr as $value) {
if ($value == $needle) {
echo $index;
break;
}
}
}

How do I loop through and change values in this PHP object?

Here is a fairly big object dumped using print_r.
https://docs.google.com/document/d/175RLhWlMQcyhGR6ffGSsoJGS3RyloEqo4EEHCL2H2vg/edit?usp=sharing
I am trying to change the values of the uploaded_files.
Towards the end of that object you'll see something like
[uploaded_files] => Array
(
[attachment] => /home2/magician/public_html/development/testing/wp-content/uploads/wpcf7_uploads/Central-Coast-Montessori-logo.jpg
[attachment2] => /home2/magician/public_html/development/testing/wp-content/uploads/wpcf7_uploads/Andrew.jpg )
My code
// move the attachments to wpcf7ev temp folder
foreach ($cf7ev_object['uploaded_files'] as $key => $uploaded_file_path) {
$new_filepath = WPCF7EV_UPLOADS_DIR . '/' . basename($uploaded_file_path);
wpcf7ev_debug("New file path is {$new_filepath}");
rename($uploaded_file_path, $new_filepath);
wpcf7ev_debug("'{$key}'is the KEY for {$uploaded_file_path}");
wpcf7ev_debug($cf7ev_object['uploaded_files']);
$cf7ev_object['uploaded_files'][$key] = $new_filepath; // this is not updating
}
To loop through it I have been using
foreach ($cf7ev_object->uploaded_files as $key => $uploaded_file_path) {
and this has worked.
But shouldn't it be
foreach ($cf7ev_object['uploaded_files'] as $key => $uploaded_file_path) {
? As '->' is for accessing methods?
And specifically I want to update the values of those uploaded_files, so to do that I need to do
$cf7ev_object['uploaded_files'][$key] = $new_filepath; // this is not updating
? But this doesn't seem to be working.
I think I need to be clear on how to access values in an object.
Thanks.
First of all, regarding the single arrow "->" that is how you reference an objects values. But I won't get into that. Since you say it works, $cf7ev_object is obviously an object.
You say you want to "access the values in the object".
var_dump($cf7ev_object);
This will spit out what is in that object. I gather you are a bit of a newbie, so I will try to help you out best I can with the limited data you provided (you may want to expand your question.
Looping is not a one-shot deal. You can have nested loops and nested loops inside of those. However, it is a resource hog if you're not careful. Here is an exercise that might help you.
$new_array = array();
foreach($cf7ev_object->uploaded_files as $key => $value) {
$new_value = $value;//do something to the $value here
$new_array[$key] = $new_value;
}
//take a look at your work now:
print_r($new_array);
I hope this helps. Note: your google doc is restricted, public can't see it.. And your question is too vague. Let me know if I can help more.
If you want to change the object array values instantly you just set it equal to the above loop result:
$cf7ev_object->uploaded_files = $new_array;
