PHP XML why I can't read the first attribute with SimpleXML? - php

The XML file I want to read looks like this:
<issues aaa="444" exportTime="Tue Jul 28 23:54:39 CEST 2015">
<issue>
<name>Testing</name>
I use this code:
$simple = file_get_contents('/url/test3.xml');
$test = new SimpleXMLElement($simple);
I can read the issue name children:
echo $test->issue[1]->name;
How can I read issues ExportTime value?
echo $test->issues[exportTime]
doesn't do anything.


Try
<?php
$str = <<<XML
<issues aaa="444" exportTime="Tue Jul 28 23:54:39 CEST 2015">
<issue>
<name>Testing</name>
</issue>
</issues>
XML;
$xml = new SimpleXMLElement($str);
var_dump($xml['exportTime']);
?>
OUTPUT
object(SimpleXMLElement)[2]
public 0 => string 'Tue Jul 28 23:54:39 CEST 2015' (length=29)

Get category from wordpress rss [php]

Hi i need help to get all categories from rss.
This is ex. of my rss feed:
<item>
<title>Coca-Cola</title>
<link>https://www.tralaaa.com/coca-cola/</link>
<comments></comments>
<pubDate>Fri, 01 Dec 2017 11:36:40 +0000</pubDate>
<dc:creator><![CDATA[Admin]]></dc:creator>
<category><![CDATA[cat1]]></category>
<category><![CDATA[cat2]]></category>
<category><![CDATA[cat3]]></category>
<category><![CDATA[cat4]]></category>
<description><![CDATA[]]></description>
<content:encoded><![CDATA[]]></content:encoded>
</item>
I try with $cat = $item->category(0); but give me the error
Call to undefined method SimpleXMLElement::category()

You cant access category using () parenthesis, you need to use [], like this:
$xml = new SimpleXMLElement(
'<item>
<title>Coca-Cola</title>
<link>https://www.tralaaa.com/coca-cola/</link>
<comments></comments>
<pubDate>Fri, 01 Dec 2017 11:36:40 +0000</pubDate>
<dc:creator><![CDATA[Admin]]></dc:creator>
<category><![CDATA[cat1]]></category>
<category><![CDATA[cat2]]></category>
<category><![CDATA[cat3]]></category>
<category><![CDATA[cat4]]></category>
<description><![CDATA[]]></description>
<content:encoded><![CDATA[]]></content:encoded>
</item>');
$cat_name1 = $xml->category[0]->__toString();
$cat_name2 = $xml->category[1]->__toString();
$cat_name3 = $xml->category[2]->__toString();
$cat_name4 = $xml->category[3]->__toString();
echo "<pre>";
print_r($cat_name1);
echo "</pre>";
echo "<pre>";
print_r($cat_name2);
echo "</pre>";
echo "<pre>";
print_r($cat_name3);
echo "</pre>";
echo "<pre>";
print_r($cat_name4);
echo "</pre>";
this will output:
you can just:
$xml->category->__toString();
it will assume you want the first category.

how can I get the value by tagnames in php?

could you give a suggestion to my code , please ?
$string = "<li>CIs = Sep Console04, 42 49, Sep11, Sep Console04<br/>Sep Console05, 42 50, Sep11, Sep Console05<br/>Sep Engine CO04, 42 53, Sep11, Sep Engine CO04</li>";
$doc = new DOMDocument();
$doc->loadHtml($string);
$result_data = $doc->getElementsByTagName('li');
But, I couldn't get the correct result . thanks all of you !
Best regards,
Anwar

I think you're really close
The following will do the trick:
$string = '<li>CIs = Sep Console04, 42 49, Sep11, Sep Console04<br/>Sep Console05, 42 50, Sep11, Sep Console05<br/>Sep Engine CO04, 42 53, Sep11, Sep Engine CO04</li>';
$doc = new DOMDocument();
$doc->loadHtml($string);
$liList = $doc->getElementsByTagName('li');
$result_data = array();
foreach ($liList as $li) {
$result_data[] = $li->nodeValue;
}
see: Get ul li a string values and store them in a variable or array php

Use single quotes before <li> and after </li>
Also change all & to & in your string, they are special characters that need to be converted to HTML:
$string = str_replace('&','&', $string);

extracting field from twitter feed using json_decode

I am trying to grab my twitter feed using the following code:
// Make the request and get the response into the $json variable
$json = $twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest();
// It's json, so decode it into an array
$result = json_decode($json);
// Access the profile_image_url element in the array
echo $result->created_at;
?>
I get the result of:
Thu Oct 25 18:40:50 +0000 2012
If I try to get the text with:
echo $result->text;
I get this error:
Notice: Undefined property: stdClass::$text in /Library/WebServer/Documents/include/twitter_noformat/items.php on line 35
A partial var_dump of my data format includes this:
{"created_at":"Thu Aug 01 16:12:18 +0000 2013",
"id":362969042497175553,
"id_str":"362969042497175553",
"text":"A warm welcome to our new international students from China, Hong Kong and Germany! http:\/\/t.co\/GLvt3GynJV",
"source":"web",
"truncated":false,"in_reply_to_status_id":null,"in_reply_to_status_id_str":null,"in_reply_to_user_id":null,"in_reply_to_user_id_str":null,"in_reply_to_screen_name":null,"user":
My question is:
created_at gives me a value. id gives me a value. Why doesn't text? I know nothing about JSON btw. I'm not a very advanced programmer, but the pattern looks the same to me.
Edit: Well I found a cool snippet that converted my twitter array to something more readable. The function goes like this:
// It's json, so decode it into an array
$result = json_decode($json);
// Access the profile_image_url element in the array
$pretty = function($v='',$c=" ",$in=-1,$k=null)use(&$pretty){$r='';if(in_array(gettype($v),array('object','array'))){$r.=($in!=-1?str_repeat($c,$in):'').(is_null($k)?'':"$k: ").'<br>';foreach($v as $sk=>$vl){$r.=$pretty($vl,$c,$in+1,$sk).'<br>';}}else{$r.=($in!=-1?str_repeat($c,$in):'').(is_null($k)?'':"$k: ").(is_null($v)?'<NULL>':"<strong>$v</strong>");}return$r;};
echo $pretty($result);
The results now look like this:
statuses_count: 583
lang: en
status:
created_at: Thu Aug 01 21:10:10 +0000 2013
id: 363044004444651522
id_str: 363044004444651522
text: #CalStateEastBay AD Sara Lillevand Judd '86 honored for her work as an athletic adminstrator. http://t.co/WzOqjIDrBw
This is strange because that makes text look like it's part of an object?
I have determined that twitter kicks back an array of objects. Those objects can have a lot of items(?) As I mentioned previously though I can echo $result->created_at; but not text. They are both at the same level of the array.
thanks in advance for your help,
Donovan

Alright here was my solution after a day of research:
$result = json_decode( $json );
echo "Text:" . $result->status->text . "<br />";
Text was a child(?) of status. I could echo created_at because it was used at two levels of the array, which I hadn't seen before. Text was inside the status object I guess.
created_at: Thu Oct 25 18:40:50 +0000 2012
favourites_count: 1
utc_offset: -25200
time_zone: Pacific Time (US & Canada)
geo_enabled: 1
verified:
statuses_count: 583
lang: en
status:
created_at: Thu Aug 01 21:10:10 +0000 2013

fullCalendar "events: 'somepage.php'" JSON Results not displaying

I am trying to get the events for my fullCalendar implementation with the "events (as a JSON feed)" built in feature.
...
event: 'calendarFill.php',
...
The php file returns the following JSON data:
[{"id":"40","title":"test four","services":"Reflexology (40), foot-soak","start":"Tue Mar 26 2013 13:00:00","end":"Tue Mar 26 2013 13:40:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test two of update. this sentence added at update.","seat":"Side Couch 9","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"},{"id":"41","title":"test four","services":"Foot-Soak, ","start":"Wed Mar 27 2013 19:00:00","end":"Wed Mar 27 2013 19:15:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test of addslashes. what's going to happen?","seat":"Front Chair 2","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"}]
The above does not work - the events are not displayed on the calendar. I've cut and pasted the code directory in my Javascript code:
events: {"id":"40","title":"test four","services":"Reflexology (40), foot-soak","start":"Tue Mar 26 2013 13:00:00","end":"Tue Mar 26 2013 13:40:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test two of update. this sentence added at update.","seat":"Side Couch 9","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"},{"id":"41","title":"test four","services":"Foot-Soak, ","start":"Wed Mar 27 2013 19:00:00","end":"Wed Mar 27 2013 19:15:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test of addslashes. what's going to happen?","seat":"Front Chair 2","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"}],
And, it does not display. But, if I edit the above to remove all the quotes that are not surrounding text values (as below), IT WORKS.
events: [{id:40,title:"test four",services:"Reflexology (40), foot-soak",start:"Tue Mar 26 2013 13:00:00",end:"Tue Mar 26 2013 13:40:00",color:"#e56b15",customerId:21,phone:"555-0404",email:"test4",notes:"test two of update. this sentence added at update.",seat:"Side Couch 9",vip:"yes",confirmed:"yes",knows_policies:"yes",customer_here:0,allDay:false},{id:41,title:"test four",services:"Foot-Soak, ",start:"Wed Mar 27 2013 19:00:00",end:"Wed Mar 27 2013 19:15:00",color:"#e56b15",customerId:21,phone:"555-0404",email:"test4",notes:"test of addslashes. what's going to happen?",seat:"Front Chair 2",vip:"yes",confirmed:"yes",knows_policies:"yes",customer_here:0,allDay:false}],
I am using the documentation at this link: http://arshaw.com/fullcalendar/docs/event_data/events_json_feed/
What am I doing wrong? Should I remove the 'json_encode' from my php and just return a string formatted like the above? I'd like to do it the 'right' way and not some work-around.
Added the php as requested:
// for connection to db
include("../includes/config.php");
include("../includes/mysql_functions.php");
// connection with db
$linkID = db_connect();
$returnValue = array();
$getEventData = mysql_query("SELECT apt_num, services, apt_date_start, apt_date_end, therapist, customer_num, notes, seat, confirmed, knows_policies, here FROM appointments", $linkID);
if ($getEventData != FALSE && mysql_num_rows($getEventData) > 0)
{
while ($theEventData = mysql_fetch_array($getEventData))
{
$getCustomerString = "SELECT first_name, middle_name, last_name, phone, email, vip FROM customer WHERE customer_num = ".$theEventData['customer_num'];
$getCustomerData = mysql_query($getCustomerString, $linkID);
if ($getCustomerData != FALSE && mysql_num_rows($getCustomerData) > 0)
{
while($theCustomerData = mysql_fetch_array($getCustomerData))
{
$customerName = $theCustomerData['first_name']." ".$theCustomerData['middle_name']." ".$theCustomerData['last_name'];
$customerPhone = $theCustomerData['phone'];
$customerEmail = $theCustomerData['email'];
$customerVip = $theCustomerData['vip'];
}
}
else

$customerName = "error";
$customerPhone = "error";

}
print json_encode($returnValue);

Markus Vetter (from Google+) found the problem. In the original code returned from my php file there is an "'" that causes an issue. I needed to 'addslashes' to my php before returning it to the jQuery/Javascript. Once that was done, the jQuery / fullCalendar code was able to render my events as expected.
A second pair of eyes does wonders! Thank you Markus Vetter!
The original code returned:
[{"id":"40","title":"test four","services":"Reflexology (40), foot-soak","start":"Tue Mar 26 2013 13:00:00","end":"Tue Mar 26 2013 13:40:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test two of update. this sentence added at update.","seat":"Side Couch 9","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"},{"id":"41","title":"test four","services":"Foot-Soak, ","start":"Wed Mar 27 2013 19:00:00","end":"Wed Mar 27 2013 19:15:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test of addslashes. what's going to happen?","seat":"Front Chair 2","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"}]
After using 'addslashes' in my php for all text fields:
[{"id":"40","title":"test four","services":"Reflexology (40), foot-soak","start":"Tue Mar 26 2013 13:00:00","end":"Tue Mar 26 2013 13:40:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test two of update. this sentence added at update.","seat":"Side Couch 9","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"},{"id":"41","title":"test four","services":"Foot-Soak, ","start":"Wed Mar 27 2013 19:00:00","end":"Wed Mar 27 2013 19:15:00","color":"#e56b15","customerId":"21","phone":"555-0404","email":"test4","notes":"test of addslashes. what\'s going to happen?","seat":"Front Chair 2","vip":"yes","confirmed":"yes","knows_policies":"yes","customer_here":"0","allDay":"false"}]

Actually solved this time! In my php file, the last value added to the $rowArray is: $rowArray['allDay'] = "false". Instead of being a text value, it needs to be the actual boolean value. This "$rowArray['allDay'] = false" fixed the problem.

I had the same issue and it was a formatting thing for me as well.
This is how my json is returning now and it is finally working.
[{"title":"Coke Trade Show","start":"2014-12-03"},{"title":"Michigan Show","start":"2014-12-04"}]
Definitely a good idea to paste your json return straight into the JS to make sure it is working.

List files in dropbox folder

Im having problems with the dropbox API.
When i try to get the metadata for my folder, i get the data output like this:
{"hash":"10f86b5b7c9c9276501f67a71ecd41c9","thumb_exists":false,"bytes":0,"path":"\/","is_dir":true,"size":"0 bytes","root":"app_folder","contents":[{"revision":7,"rev":"7069e0896","thumb_exists":true,"bytes":19749,"modified":"Tue, 20 Mar 2012 05:06:43 +0000","client_mtime":"Mon, 26 Sep 2011 11:50:43 +0000","path":"\/1_sml.jpg","is_dir":false,"icon":"page_white_picture","root":"dropbox","mime_type":"image\/jpeg","size":"19.3 KB"},{"revision":6,"rev":"6069e0896","thumb_exists":true,"bytes":15797,"modified":"Tue, 20 Mar 2012 05:06:43 +0000","client_mtime":"Mon, 26 Sep 2011 11:51:09 +0000","path":"\/2_sml.jpg","is_dir":false,"icon":"page_white_picture","root":"dropbox","mime_type":"image\/jpeg","size":"15.4 KB"},{"revision":5,"rev":"5069e0896","thumb_exists":true,"bytes":13349,"modified":"Tue, 20 Mar 2012 05:06:43 +0000","client_mtime":"Mon, 26 Sep 2011 11:51:26 +0000","path":"\/3_sml.jpg","is_dir":false,"icon":"page_white_picture","root":"dropbox","mime_type":"image\/jpeg","size":"13 KB"},{"revision":4,"rev":"4069e0896","thumb_exists":true,"bytes":8838,"modified":"Tue, 20 Mar 2012 05:06:43 +0000","client_mtime":"Mon, 26 Sep 2011 11:51:46 +0000","path":"\/4_sml.jpg","is_dir":false,"icon":"page_white_picture","root":"dropbox","mime_type":"image\/jpeg","size":"8.6 KB"},{"revision":3,"rev":"3069e0896","thumb_exists":true,"bytes":99646,"modified":"Tue, 20 Mar 2012 04:57:58 +0000","client_mtime":"Tue, 20 Sep 2011 14:14:26 +0000","path":"\/bg.jpg","is_dir":false,"icon":"page_white_picture","root":"dropbox","mime_type":"image\/jpeg","size":"97.3 KB"}],"icon":"folder"}
My problem is that i would like get the output for each the image/file name only.. But i can find the right way to do it.. i through i could do it this way:
$info = json_encode($dropbox->getMetaData(''));
foreach($info->contents->path as $file){
echo $file;
}
But i get this error:
Warning: Invalid argument supplied for foreach() in /home/djrasmusp/rasmusp.com/db/index.php on line 16
But is there anyone that can give me a helping hand with my problem?

Try json_decode instead of json_encode (and maybe use second parameter to produce associated array instead of stdClass).

I had the same problem, here is my solution:
$metaData = $dropbox->metaData($path);
foreach($metaData['body']->contents as $file){
$f = str_replace("/", "", $file->path);
echo "<li>$f</li>";
}

tested by me :)
require_once('bootstrap.php');
$metaData = $dropbox->metaData();
foreach($metaData['body']->contents as $file)
{
echo "<pre>";
echo $file->path;
}
