PHP for directory listing - php

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
[response] => Array

[0] => SimpleXMLElement Object

)
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);

Export Array of SimpleXMLElement objects to MySQL Database

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.

Why is my SimpleXMLElement data truncated?

I retrieve the following XML data:
<?xml version="1.0" encoding="UTF-8"?>
<JMF xmlns="http://www.CIP4.org/JDFSchema_1_1" MaxVersion="1.4" SenderID="HP Hybrid Elk JMF" TimeStamp="2014-02-19T07:42:11+00:00" Version="1.4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="JMFRootMessage">

<Response ID="Rgdhhhdfhd" ReturnCode="0" Type="KnownDevices" refID="gdhhhdfhd" xsi:type="ResponseKnownDevices">
<DeviceList>
<DeviceInfo DeviceCondition="OK" DeviceID="HPSSPP-SM" DeviceStatus="Running" StatusDetails="Running"/>
<DeviceInfo CounterUnit="Impressions" DeviceCondition="OK" DeviceID="192.168.1.101" DeviceStatus="Running" ProductionCounter="12345678" StatusDetails="Indigo: Printing" xmlns:jdf="http://www.CIP4.org/JDFSchema_1_1">
<GeneralID IDUsage="hpCustomerImpressionCounter" IDValue="12345678.0"/>
</DeviceInfo>
<DeviceInfo CounterUnit="Impressions" DeviceCondition="OK" DeviceID="192.168.1.102" DeviceStatus="Running" ProductionCounter="23456789" StatusDetails="Indigo: Printing" xmlns:jdf="http://www.CIP4.org/JDFSchema_1_1">
<GeneralID IDUsage="hpCustomerImpressionCounter" IDValue="23456789.0"/>
</DeviceInfo>
</DeviceList>
</Response>
</JMF>
I load it into a SimpleXMLElement:
<?php
$jdf_response = new SimpleXMLElement($xml_response);
And I can then display it like so:
<pre>
<?php print_r($jdf_response->Response->DeviceList); ?>
</pre>
Which gives the following output:
SimpleXMLElement Object
(
[DeviceInfo] => Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[DeviceCondition] => OK
[DeviceID] => HPSSPP-SM
[DeviceStatus] => Running
[StatusDetails] => Running
)
)
[1] => SimpleXMLElement Object
(
[#attributes] => Array
(
[CounterUnit] => Impressions
[DeviceCondition] => OK
[DeviceID] => 192.168.1.101
[DeviceStatus] => Running
[ProductionCounter] => 12345678
[StatusDetails] => Indigo: Printing
)
[GeneralID] => SimpleXMLElement Object
(
[#attributes] => Array
(
[IDUsage] => hpCustomerImpressionCounter
[IDValue] => 12345678.0
)
)
)
[2] => SimpleXMLElement Object
(
[#attributes] => Array
(
[CounterUnit] => Impressions
[DeviceCondition] => OK
[DeviceID] => 192.168.1.102
[DeviceStatus] => Running
[ProductionCounter] => 23456789
[StatusDetails] => Indigo: Printing
)
[GeneralID] => SimpleXMLElement Object
(
[#attributes] => Array
(
[IDUsage] => hpCustomerImpressionCounter
[IDValue] => 23456789.0
)
)
)
)
)
So far so good. But I need to get the data from the DeviceInfo array, so I modify the code:
<pre>
<?php print_r($jdf_response->Response->DeviceList->DeviceInfo); ?>
</pre>
But instead of three SimpleXMLElement objects, I get only the first.
SimpleXMLElement Object
(
[#attributes] => Array
(
[DeviceCondition] => OK
[DeviceID] => HPSSPP-SM
[DeviceStatus] => Running
[StatusDetails] => Running
)
)
What am I doing wrong?
Update:
The reason I was using print_r() in the first place because because I was getting no output from the following code:
<?php
$addresses = array();
foreach ($jdf_response->Response->DeviceList->DeviceInfo as $device) {
$addresses[] = $device->{'#attributes'}'DeviceID'];
}
print_r($addresses);
Example #4 Accessing non-unique elements in SimpleXML
When multiple instances of an element exist as children of a single parent element,
normal iteration techniques apply.
Data is still there, You just have to use an iterator like:
foreach($jdf_response->Response->DeviceList->DeviceInfo as $device)
{
print_r($device);
}

Get Methods from REST call

I would like to get methods from REST XML file via PHP.
I have local REST file, which is in this format:
SimpleXMLElement Object
(
[doc] => SimpleXMLElement Object
(
)
[resources] => SimpleXMLElement Object
(
[#attributes] => Array
(
[base] => https://**url**
)
[resource] => Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[path] => xml/{accesskey}/project
)
[param] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => accesskey
[style] => template
[type] => xs:string
)
)
[method] => SimpleXMLElement Object
(
[#attributes] => Array
(
[id] => getAllProjects
[name] => GET
)
[response] => SimpleXMLElement Object
(
[representation] => SimpleXMLElement Object
(
[#attributes] => Array
(
[mediaType] => application/xml; charset=utf-8
)
)
)
)
... and so on
I have the following code, but it returns just the first method name:
$file="application.wadl";
$xml = simplexml_load_file($file);
foreach($xml->resources[0]->resource->method->attributes() as $a => $b) {
echo $b,"\n";
}
I would like to extract all of them, not just the first one. How to do that?
Rather than looping over the attributes of one element, you need to loop over all the elements with the same name. Due to the magic of SimpleXML, this is as simple as this:
foreach($xml->resources->resource->method as $method) {
echo $method['id'],"\n";
}
When followed immediately by another operator, as with ->resources, SimpleXML assumes you just want the first element with that name. But if you loop over, it will give you each of them, as a SimpleXML object.
EDIT : It looks like the nesting of your XML means you need some form of recursion (you need to look at $xml->resources->resource->resource->resource->method etc).
Something like this perhaps (untested example)?
function get_methods($base_url, $node)
{
$all_methods = array();
// Child resources: build up the path, and recursively fetch all methods
foreach ( $node->resource as $child_resource )
{
$child_url = $base_url . '/' . (string)$child_resource['path'];
$all_methods = array_merge(
$all_methods,
get_methods($child_url, $child_resource)
);
}
// Methods in this resource: add to array directly
foreach ( $node->method as $method )
{
$method_url = $base_url . '/' .(string)$method['id'];
$all_methods[$method_url] = (string)$method['id'];
}
return $all_methods;
}
print_r( get_methods('/', $xml->resources) );
Incidentally, print_r won't always give you the best view of a SimpleXML object, because they are actually wrappers around non-PHP code. Try this simplexml_dump() function instead.

how to get to a specific part of this nested array/object

This is driving me crazy, I am trying to get to a specific part of this object and it is driving me crazy, here is the object contents:
XMLHandler Object
(
[doc:XMLHandler:private] => SimpleXMLElement Object
(
[#attributes] => Array
(
[state] => Live
)
[newsListItem] => Array
(
[0] => SimpleXMLElement Object
(
[#attributes] => Array
(
[href] => http://api.contentplus.co.uk/6cb5ea15-d6b1-4c40-9db7-cb2a3315080b/news/800773226/
)
[id] => 800773226
[publishDate] => 2011-10-24T10:04:49
[lastModifiedDate] => 2011-10-24T11:20:40
[headline] => Relationships matter on social media
)
)
)
[format] => html
)
I want to get the value of [id] I am trying to access it like this:
echo $niList->doc->newsListItem[0]->id;
but this is giving me nothing, I know I am close (well I hope I am) but I just cant quite get it right, could anyone help please.
Thanks all.
Your object dump says
doc:XMLHandler:private
which means doc is a private property of XMLHandler. As such, you can only access it from within that object via $this. But you are trying to access it from outside the object when you do
echo $niList->newsListItem[0]->id;
This wont work. Add a method to that XMLHandler object that does what you want to do with that newslistitem id. Also see the chapter on Visibility in the PHP Manual:
http://docs.php.net/manual/en/language.oop5.visibility.php

How to load a simplexmlobject file into a variable

I am going crazy here...
I already have a SimpleXMLElement Object so it is not an XML file...
I got it stored in a file object.txt
Now i want to put this object into a variable, but i can't get it to work...?
the SimpleXMLElement Object looks like this:
SimpleXMLElement Object
(
[PubmedArticle] => Array
(
[0] => SimpleXMLElement Object
(
[MedlineCitation] => SimpleXMLElement Object
(
[#attributes] => Array
(
[Owner] => NLM
[Status] => In-Process
)
[PMID] => 20538400
[DateCreated] => SimpleXMLElement Object
(
[Year] => 2010
[Month] => 07
[Day] => 08
)
[Article] => SimpleXMLElement Object
(
[#attributes] => Array
(
[PubModel] => Print-Electronic
)
.....etc etc....
how do i put this into a variable??
i tried this:
$simplexml = file_get_contents('object.xml');
$simplexml should be an array
Loading simplexml from file: simplexml_load_file: $a = simplexml_load_file('object.xml');
If you need something else, please explain.
If your 'object.xml' file contains the above example and not actual XML, it looks a lot like you are using the results of a vardump, and you possibly wish to load that into a (or several) SimpleXMLElementObject(s)...
So, really, you have a string inside of a text file, and you want to parse out the contents. I found this: converting text file into xml using php? and thought it would be a good starting point.
