I have a function which gets me all students enrolled on a course on my local db. I need to cross check their usernames with usernames from a csv and output the ones who are NOT in the csv
Here's the output of the function:
Array (
[as.domingos] => stdClass Object ( [username] => as.domingos )
[m.menas] => stdClass Object ( [username] => m.menas )
[m.bexiga] => stdClass Object ( [username] => m.bexiga )
[spm] => stdClass Object ( [username] => spm ) )
And here's the csv format:
username;email;course1
userA;a#gmail.com;ABC
userB;b#gmail.com;ABC
m.menas;m.menas#gmail.com;ABC
m.bexiga;m.bexiga#gmail.com;ABC
spm;spm#gmail.com;ABC
My first thought was calling array_diff but it's not working. In this example above, the output would be as.domingos, because it's not in the csv.
$fp=fopen('sample.csv','r');
$numberofquitters=0;
$enrolinfo=' ';
fgetcsv($fp,1000,";");
while(($data=fgetcsv($fp,1000,";"))!==FALSE){
if(array_diff((array)$xpta->username,$data)){
//echo $xpto->username;
$enrolinfo=get_string('quitter','local_ecoclipaluno');
$numberofquitters++;
}
Any ideas?
Cheers.

Having real issues with this. I want to be able to get a value from this data which is returned via an API.
ie get value by
$CM_user_customfields['Organisation'],
$CM_user_customfields->Organisation.
is that even possible? I have tried loops and rebuilding the array but i always end up with a similar results and perhaps overthinking it.
I can't use the [int] => as the number of custom fields will be changing a lot.
$CM_user_customfields = $CM_details->response->CustomFields ;
echo '<pre>' . print_r( $CM_user_customfields, true ) . '</pre>';
// returns
Array
(
[0] => stdClass Object
(
[Key] => Job Title
[Value] => Designer / developer
)
[1] => stdClass Object
(
[Key] => Organisation
[Value] => Jynk
)
[2] => stdClass Object
(
[Key] => liasoncontact
[Value] => Yes
)
[3] => stdClass Object
...
many thanks, D.
I recommend convert to associative array first:
foreach($CM_user_customfields as $e) {
$arr[$e->Key] = $e->Value;
}
Now you can access it as:
echo $arr['Organisation'];
You can also achieve it by: (PHP 7 can convert stdClass and will do the trick)
$arr = array_combine(array_column($CM_user_customfields, "Key"), array_column($CM_user_customfields, "Value")));
I'm creating an array of objects (or trying to) that looks like this:
Array
(
[1] => stdClass Object
(
[date] => 2016-09-28
)
[5] => stdClass Object
(
[date] => 2016-09-28
)
[2] => stdClass Object
(
[date] => 2016-09-29
)
[0] => stdClass Object
(
[date] => 2016-09-30
)
[4] => stdClass Object
(
[date] => 2016-09-30
)
[3] => stdClass Object
(
[date] => 2016-09-30
)
)
The trouble that I'm having is that I need can't work out how to check if an object with date->$date already exists.
I need an array of 'days' that I can then go on to add workshops to the corresponding days, not to a new object each time.
Can anyone make a suggestion?
EDIT
To put this in context, I'm iterating through a bunch of wordpress posts (of type 'workshop' in this case) which all have a piece of date meta. On my way through the loop I want to
Get the date(day)
Check if that date exists in the array
If not, add the date to the array
Then add the workshop object to that date array
What I should therefor end up with is an array containing three or four unique dates, each with an array of workshop objects.
Array(
Date 1(
Workshop(
Title, etc
),
Workshop()
)
Date 2(
Workshop(
Title, etc
)
Workshop()
)
)
My apologies, I'm sure my structure is off - this is a little advanced for me. Thanks for looking.
What you need is something like this. You can have a function to group your result.
function groupWorkShopsByDate($first_array){
$result_arr = array();
foreach( $first_array as $workShop ){
$result_arr[ $workShop->date ][] = $workShop;
}
return $result_arr;
}
Hope this helps!
i wont to list a set of files in a directory and the files in its sub directory using a loop rather than the function
as im getting the information about the directory through an xml based webdav and php native functions are infertile so please understand the issue has not yet been lodged here
$urlloc is used to remove the same directory from being looped again
foreach ($xml as $key) {
if(empty($key->propstat->prop->resourcetype[0])){
echo $key->href."<br/>";//files are printed, for debugging perposes im printing it
}else{
$Nurlloc=$key->href;
if ($Nurlloc!=$urlloc){
echo "<b>".$Nurlloc."</b><br/>";//directorys printed in bold for debugging
$urlloc=$Nurlloc;
//gtndirdown()
above is the method im getting to know if its a directory or not
NOTE i want to be able to make this code loop through and get me all the files in the directory i will also post the array of files im getting

iv been stuck in this issue for 4 days and i have would like if some one could come up with a logic for this issue
maybe this is an idea that you can implement in your logic
// the name of directory
$dir='path_to_your_directory';
$files = array_slice(scandir($dir), 2);
print_r($files);
I have a SOAP Response from a Web Service and have extracted the XML data as a SimpleXMLElement. I have then iterated through this object to extract the various fields I need and save them into an array, which becomes an array of SimpleXMLElement objects.
I am now trying to export this data into a MySQL Database which, according to my research, means turning the array into a String and then using mysql_query("INSERT INTO (whatever) VALUES (whatever)");. I have tried implode and serialize but neither work and I get the error:
Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement' is not allowed'
This is what the array I have created from the SimpleXMLELement looks like:
Array
(
[0] => Array
(
[uid] => SimpleXMLElement Object
(
[0] => WOS:000238186400009
)
[journal] => SimpleXMLElement Object
(
[#attributes] => Array
(
[type] => source
)
)
[publication] => SimpleXMLElement Object
(
[#attributes] => Array
(
[type] => item
)
[0] => Abundance of hedgehogs (Erinaceus europaeus) in relation to the density and distribution of badgers (Meles meles)
)
[year] => 2006
[author1] => SimpleXMLElement Object
(
[0] => Young, RP
)
[address] => SimpleXMLElement Object
(
[0] => Cent Sci Lab, Sand Hutton, Yorks, England
)
[author2] => SimpleXMLElement Object
(
[0] => Davison, J
)
[author3] => SimpleXMLElement Object
(
[0] => Trewby, ID
)
[citations] => SimpleXMLElement Object
(
[#attributes] => Array
(
[local_count] => 15
[coll_id] => WOS
)
)
) ... etc ...
)
Can anyone help me with the method to get this data into my database, please? Do I need to change it into (yet) another format?
You have to iterate through your array to create a new array fulfilled with strings instead of SimpleXMLElement, such as :
<?php
// your array (already built)
$arraySimpleXml = array(
"example1" => new SimpleXMLElement("<test>value</test>"),
"example2" => new SimpleXMLElement("<test>value2</test>")
);
// output array, to store in database
$result = array();
foreach($arraySimpleXml as $key => $simpleXml) {
$result[$key] = $simpleXml->asXML();
}
// gets your result as a string => you can now insert it into mysql
$dbInsertion = serialize($result);
?>
So I worked out how to change the data into a standard array rather than an array of SimpleXMLElements so that I can successfully insert it into a MySQL database.
When iterating the SimpleXMLElement object to extract the data I needed I cast the type as String so that now my array has the format (as opposed to above):
Array
(
[0] => Array
(
[uid] => WOS:000238186400009
[journal] => JOURNAL OF ZOOLOGY
[publication] => Abundance of hedgehogs (Erinaceus europaeus) in relation to the density and distribution of badgers (Meles meles)
[year] => 2006
[author1] => Young, RP
[address] => Cent Sci Lab, Sand Hutton, Yorks, England
[author2] => Davison, J
[author3] => Trewby, ID
[citations] => 15
)
)
Thought I'd post this in case anyone has a similar problem in future. To do this, when iterating the data instead of:
$uid = $record->UID;
I did:
$uid = (string)$record->UID;
For each of the data fields I required. This ensures the data is stored as a String and so removes the SimpleXMLElement format.
I've seen similar questions on here but I can't seem to apply the solutions to my problem. I have a variable called $results which I got from an API. I'll change the proper nouns so as to protect my work's customers:
stdClass Object
(
[out] => stdClass Object
(
[count] => 2
[transactions] => stdClass Object
(
[RealTimeCommissionDataV2] => Array
(
[0] => stdClass Object
(
[adId] => 12345678
[advertiserId] => 123456789
[advertiserName] => Chuck E. Cheese, inc.
[commissionAmount] => 50
[country] => US
[details] => stdClass Object
(
)
[eventDate] => 2009-11-16T09:44:25-08:00
[orderId] => X-XXXXXXXXXX
[saleAmount] => 0
[sid] => 123456789
[websiteId] => 2211944
)
[1] => stdClass Object
(
[adId] => 987654321
[advertiserId] => 12345
[advertiserName] => Chorizon Wireless.
[commissionAmount] => 50
[country] => US
[details] => stdClass Object
(
)
[eventDate] => 2009-11-16T09:58:40-08:00
[orderId] => X-CXXXXXX
[saleAmount] => 0
[sid] => 61-122112
[websiteId] => 1111922
)
)
)
)
)
I shortened it to two entries here but the number of entries will vary, it's the result of a check for transactions in the past hour, there may sometimes be only one and sometimes as many as a dozen.
I want to assign these entries to variables like websiteId1 websiteId2 etc. I know I need to do a foreach loop but can't seem to figure it out. How can I write it so that I get the "[details]" as well?
foreach ($results->out->transactions->RealTimeCommissionDataV2 AS $commissionData) {
// you can access the commissionData objects now, i.e.:
$commissionData->adId;
$commissionData->details;
}
<?
foreach ($result->out->transactions->RealTimeCommissionDataV2 as $item)
{
// do somthing with each item.
print_r($item);
// or the details array
$num_details = sizeof($item->details)
}
I think this is what you want.
EDIT
Updated based on some notes in the documentation. Specifically, these two
a numerically indexed array will not
produce results unless you use
EXTR_PREFIX_ALL or
EXTR_PREFIX_INVALID.
Prefixes are automatically separated
from the array key by an underscore
character.
echo extract( $results->out->transactions->RealTimeCommissionDataV2, EXTR_PREFIX_ALL, 'websiteId' );
// test the extract
print_r( $websiteId_0 );
