I am currently trying to display a RSS feed in a PHP page, but it seems to have a problem between the xslt_create() function and PHP5.
<?php
$xh = xslt_create();
$file=fopen(WEB_DIR . 'assets/_xml/rss.xml','r');
$xml=fread($file,16384);
fclose($file);
$file=fopen(WEB_DIR . 'assets/_xml/rss.xslt','r');
$xsl=fread($file,16384);
fclose($file);
$arguments = array(
'/_xml' => $xml,
'/_xsl' => $xsl
);
$result = xslt_process($xh, 'arg:/_xml', 'arg:/_xsl', NULL, $arguments);
xslt_free($xh);
print "$result";
?>
I get the error
Fatal error: Call to undefined
function xslt_create() in
What do I have to do to correct this issue ?
xslt_create only exists in PHP 4 - as this approach to parsing XML was removed in PHP 5.
As such, I'd recommend updating your code to use one of the current PHP 5 approaches as listed within the XML Manipulation section of the manual. (The XSL extension provides a XSLTProcessor class that is probably the nearest direct equivalent.)

I've started writing a scraper for one site that will also have a crawler, since I need to go through some links, but I'm getting this error :
PHP Fatal error: Uncaught Error: Call to a member function find() on
null in D:\Projekti\hemrank\simple_html_dom.php:1129 Stack trace:
0 D:\Projekti\hemrank\scrapeit.php(37): simple_html_dom->find('ul')
1 D:\Projekti\hemrank\scrapeit.php(19): ScrapeIt->getAllAddresses()
2 D:\Projekti\hemrank\scrapeit.php(55): ScrapeIt->run()
3 {main} thrown in D:\Projekti\hemrank\simple_html_dom.php on line 1129
When I var_dump the $html variable I get the full html with all the tags, etc, that's why it's strange to me that it says "Call to a member function find() on null", when there's actually value in the $html. Here's the part of the code that's not working :
$html = new simple_html_dom();
$html->load_file($baseurl);
if(empty($html)){echo "HTTP Response not received!<br/>\n";exit;}
$links = array();
foreach ($html->find('ul') as $ul) {
if(!empty($ul) && (count($ul)>0))
foreach ($ul->find('li') as $li) {
if(!empty($li) && (count($li)>0))
foreach ($li->find('a') as $a) {
$links[] = $a->href;
}
else
die("NOT AVAILABLE");
}
}
return $links;
}
Is this a common problem with PHP simple HTML DOM parser, is there a solution or should I switch to some other kind of scraping?
I just searched for the lib you are using, this is line 1129:
return $this->root->find($selector, $idx, $lowercase);
So your error message is telling you that $this->root inside the class is null, therefore no find() method exists!
I'm no expert on the lib, as I use the awesome DOMDocument for parsing HTML, but hopefully this should help you understand what has happened.
Also, $html will never be empty in that code of yours, you already populated it when you instantiated it!
I suggest the following change:
$html->load_file($baseurl); to $html = file_get_html($baseurl);
On my VPS server it works with $html->load_file($baseurl); but on my dedicated local server it only works with $html = file_get_html($baseurl);
This solved my problem:
- Call to a member function find() on null
- simple_html_dom.php on line 1129
I have a PHP extension that is in C++ and I used SWIG to wrap it. I am trying to create a class that is implemented in C++ as such:
Package(const std::map<std::string,std::string> &input_map, const std::queue<std::string> &dates_queue);
in PHP by using this script:
<?php
require "prq.php";
$input = array("dataset" => "a050119", "station" => "a050119", "flag" => "1");
$dates = array(1 => "read;chunk;2015-07-01 00:00;2015-07-02 00:00");
$package = new Package($input, $dates);
?>
but I get the error:
PHP Fatal error: Type error in argument 1 of new_Package. Expected SWIGTYPE_p_std__mapT_std__string_std__string_t in /home/jlahowetz2/development/package-request-queue/swig/prq.php on line 230
which makes sense... I have no clue how to implement a std::map in PHP. I looked at the C++ wrapper that was created by SWIG and found a type conversion for this:
static swig_type_info _swigt__p_std__mapT_std__string_std__string_t = {"_p_std__mapT_std__string_std__string_t", "std::map< std::string,std::string > *", 0, 0, (void*)0, 0};
My question is: how do I use this type conversion in PHP to pass a std::map to my constructor? Thank you much.
add
%template(mapStuff) std::map<std::string, std::string>;
to the interface file then in PHP treat it like a proxy class.
I am trying to parse many HTML tables, with the URLs stored in the database. The current problem with my code is that it will fail on a different table every time. Here is the part of the code that gets the error:
while ($sqlrow = mysqli_fetch_row($res)) {
echo "Started Processing Table " . $tables . PHP_EOL;
$tables++;
$data = file_get_contents($sqlrow[1]);
$dom->loadHTML($data);
$dom->preserveWhiteSpace = false;
$teamtable = $dom->getElementById("reTeamTable");
$teamrows = $teamtable->getElementsByTagName('tr');
The lines that usually fails is either the "getElementById" command or the "getElementsByTagName" command. The error I am getting is: "PHP Fatal error: Call to a member function getElementsByTagName() on a non-object in /scouting/teamlist.php on line 20". I don't understand why this is getting an error on a different URL every time.
Its means that $dom doesnt find element with id="reTeamTable" ( $teamtable is null ). Before call getElementsByTagName , check $teamtable on empty.
For months I've been running the "Box Rest Client" lib by Angela R that employs the following code to parse curl responses from the box API:
$xml = simplexml_load_string($res);
Today, after the code loops through dozens of request/responses I generate this following error:
ErrorException [ Warning ]: simplexml_load_string(): Entity: line 9:
parser error : Comment not terminated
This happened in 2 straight attempts to run the code - and now seems to have gone away without any changes to anything.
Interested if anyone knows what is up with that?
I have put a catch for this case if its useful to anyone using this lib (for the next month or so before its deprecated by box api 2.0)
private function parse_result($res) {
try {
$xml = simplexml_load_string($res);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
return $array;
} catch (Exception $e){
$error = 'xml parsing error: '. $e->getMessage(). "<br>";
return array('status' => $error );
}
}
It's possible it is related to including two minus signs -- inside of an HTML comment. For example:
<!-- this is my comment--but not a very good one. -->
The two dashes in the middle of the comment causes problems with the parser.
First let me say sorry for the amount of code I'm posting below I'm going to try and keep it as short as possible but this is built on top of my MVC (lightweight-mvc)
Ok So my Problem is that for some reason php is throwing a fatal error on code that should not be being used in my current code,
So how this works I have my MVC witch used the first 2 parts of the url to know what its loading, the problem is I'm building a Moulder CMS into my MVC so it's boot strapping twice,
So here is my Problem,
http://{domain}/admin/control/addon/uploader/method/uploadCheck/
I'm using the above now let me explain a little into that the /admin/control are for the main MVC System it auto-loads the Admin controller then fires the controlAction method from the controller much the same as most MVC's,
The next part are URL paramters that build an array the same as GET or POST would
array('addon'=>'uploader', 'method'=>'uploadCheck')
So from that my control action will auto load as is the code below
public function controlAction(){
global $_URL;
if(cleanData::URL("addon")){
$addonName = "addon_".cleanData::URL("addon");
$methodName = (cleanData::URL("method"))? cleanData::URL("method")."Action" : "indexAction";
echo $methodName;
$addon = new $addonName();
$addon->$methodName();
return;
}else{
$this->loadView("CMS/controll");
}
}
cleanData::URL is an abstract method that just returns the value of the key provided though addSlashes()
So as you can see from the code below it will then use the autoloader to load the module(AKA addon)
Just so you can follow the auto loader works in a simpler version of the Zend Frame work autoloader _ so you have class name addon_admin that would be inside file admin.php that is in the folder addon so the autoloader will load addon/admin.php
So As above with my URL and controlAction it's loading addon/uploader.php and as such this is the contents
<?php
class addon_uploader extends Addons{
public function uploadCheckAction(){
echo 0;
}
public function uploaderAction(){
if (!empty($_FILES)) {
$tmpFile = $_FILES['Filedata']["tmp_name"];
$newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']);
move_uploaded_file($tmpFileName, $newLock);
$POSTback = array(
'name' => $_FILES['Filedata']['name'],
'type' => $_FILES['Filedata']['type'],
'tmp_name' => $newLock,
'error' => $_FILES['Filedata']['error'],
'size' => $_FILES['Filedata']['size']
);
echo json_enocde($POSTback);
}
}
}
?>
But as you can see from my URL its using the uploadCheckAction method witch for debugging i have set so it always says false (AKA 0),
But i seem to get this error:
Fatal error: Only variables can be passed by reference in C:\xampp\htdocs\FallenFate\addon\uploader.php on line 11
But line 11 is $newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']); witch should not be being used could any one provide any help into why this would occur and how i could fix it
end() PHP Manual needs an expression of a single variable (more precisely an array), but not a function return value or any other type of expression.
I think that's basically the cause of your error, more specifically with your code:
$newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']);
you're even driving this far beyond any level of treatment PHP can cope with:
you concatenate an array with a string (which results in a string).
you run end() on that string - not on a variable, not even an array.
I have no clue what you try to do with the code, but I can try:
$filename = $_FILES['Filedata']['name'];
$parts = explode('/', $tmpFile);
$last = end($parts);
$newLock = "../uploads/". $last . $filename;
Or probably even only this:
$filename = $_FILES['Filedata']['name'];
$newLock = "../uploads/". $filename;
